Confusing☁️Deep in it

Silent testimony? Revealing the mystery

Episode 1

At night, Qi Sizhe, wearing a black hooded jacket, silently observed a man who behaved strangely and stared at the street lights. Later, the man appeared in a nightclub partying. He soon had a fantasy, and then stabbed a girl with a knife.

A murder occurred at 788 Nightclub. Wan Guoxin, Zhu Qingyue and others rushed to the scene of the crime immediately.Han Feng arrived at the scene first. The nightclub was in chaos and everyone ran out for their lives.Han Feng saw the suspect in the parking lot on the top floor. He was still hallucinating, shouting why don't you let me go, and then started to climb the railing. Han Feng temporarily stabilized him, but the flashlight suddenly went out, and the man rushed to the fence again as if he had seen a ghost. Fortunately, Han Feng grabbed the man's hand in time to prevent him from falling.

The man said he didn't want to die yet and begged Han Feng not to let go. Han Feng held him tightly.The man suddenly had another hallucination and struggled to break free from Han Feng's hand. The situation was very urgent. Seeing that the situation was not good, Wan Guoxin quickly pushed a cart filled with waste. The man fell off, was blocked by a billboard, and then fell onto the cart. He was unconscious, but still breathing.

Qi Sizhe reported to the Chengguan Branch of the Hecheng City Public Security Bureau as the director of the forensic office. Director Bai Nian asked him if there was any other reason for his return this time. Qi Sizhe did not tell the truth and only said that he wanted to change his environment.In the corridor, Qi Sizhe met two subordinate forensic doctors, Gao Yuan and intern forensic doctor Qiu Lanzi. After learning that the blood sample of the man who fell from the building had been sent to the forensic room, Qi Sizhe immediately went to the forensic room.

The man who fell was named Li Yiqi. Surveillance footage obtained from Han Feng showed that Li Yiqi had been in contact with drug dealer Jiang Fei at the nightclub.Qi Sizhe asked him to take a blood sample. When he came out of the forensic room, he ran into Han Feng and Zhu Qingyue. Han Feng was surprised that he was here. Qi Sizhe did not answer him, but went around him to say hello to Zhu Qingyue.The police station arrested Wang Qiang, a drug addict. Han Feng showed him Jiang Fei's photo, and he recognized him.Li Yiqi's drug inspection report came out, and even the drug rough diamonds that Qi Sizhe was concerned about were not detected.Zhu Qingyue asked Dr. Zhao what things can cause hallucinations. Dr. Zhao mentioned rough diamonds. Uncut diamonds can damage the brain and cause serious hallucinogenic and harmful behaviors. The last case a few years ago was a 16-year-old girl who suffered brain damage after taking it and became a vegetative state.

Qi Sizhe posted the photo of Jiang Fei on the whiteboard. It turned out that he was secretly investigating Jiang Fei and tracked him all the way to Jiang Fei's residence.Han Feng took people to Jiang Fei's residence to search and found Jiang Fei's body curled up in the bathtub. Zhu Qingyue told him that no known drugs were detected in Li Yiqi's body.Jiang Fei had no external injuries, and Qi Sizhe initially determined that his death was accidental.Han Feng asked Qi Sizhe the purpose of his transfer. Qi Sizhe asked Han Feng the reason why he switched from a police detective to a criminal investigation. Han Feng did not answer, so Qi Sizhe turned and went downstairs.

Han Feng always felt that Jiang Fei and Li Yiqi's cases were related. Zhu Qingyue reminded him that if he was involved in drug trafficking, he should hand over the investigation notebook to the anti-drug brigade.Han Feng asked Qi Sizhe again about his motives for transferring here, and Qi Sizhe asked him again.Surveillance video showed that a man in black appeared downstairs at Jiang Fei's house, and this man also appeared in the nightclub.When Qiu Lanzi died in the forensic room, Han Feng thought of Qi Sizhe first.Director Bai Nian ordered Han Feng and Zhu Qingyue to solve the case as soon as possible. Zhu Qingyue said that Qi Sizhe appeared at the crime scene many times in the surveillance footage, and the last person Qiu Lanzi saw was also Qi Sizhe. Han Feng agreed with Zhu Qingyue's judgment that Qiu Lanzi should have found something on Jiang Fei's body before his death.

After Qi Sizhe learned that Qiu Lanzi died of acute potassium cyanide poisoning, he recalled his last meeting with Qiu Lanzi. The two collided at the corner of the stairs, and Qiu Lanzi helped him pick up bottled water.Han Feng and Zhu Qingyue took notes for Qi Sizhe, but Qi Sizhe insisted on waiting for the autopsy report and water test results to come out before discussing.The results came out. Qiu Lanzi died of potassium cyanide, but there was no potassium cyanide in the water, including Qi Sizhe's personal belongings.

Episode 2

Qi Sizhe concluded that potassium cyanide may have been in Qiu Lanzi's body for a long time, which was consistent with the conclusion of Gao Yuan's autopsy report.Han Feng asked Qi Sizhe if his special transfer had something to do with the past. Qi Sizhe refused to confess. Although Han Feng did not believe that Qi Sizhe would kill Qiu Lanzi, in his heart, it didn't matter whether he believed it or not. What mattered was the truth.

Gao Yuan also tested Qi Sizhe's water. Qiu Lanzi and Qi Sizhe gave each other the wrong water, but there was nothing wrong with the water.Zhu Qingyue followed Director Bai's instructions and disclosed some case information to Qi Sizhe. Qi Sizhe deduced the cause of Qiu Lanzi's poisoning. The murderer drugged Qiu Lanzi through stomach medicine. The attack would not have happened so quickly. Unfortunately, Qiu Lanzi took the wrong soda water from Qi Sizhe, which accelerated the dissolution of the stomach medicine.Dr. Zhao tested the last pill left in Qiu Lanzi's medicine bottle, which contained potassium cyanide. Like Qi Sizhe's inference, Zhu Qingyue told Qi Sizhe that he was temporarily free of suspicion. Qi Sizhe wanted to participate in the case, but Han Feng asked him to avoid it.

Zhu Qingyue asked Director Bai about Qi Sizhe's past. Director Bai said that Qi Sizhe had been in a serious car accident, but it only took one year to achieve the rehabilitation effect that others could achieve in three to five years.Although he is very outstanding, he is also very stubborn. Like Han Feng, Director Bai hopes that Zhu Qingyue can bring Qi Sizhe and Han Feng together to handle the case properly.

At night, Qi Sizhe left the police station, and Han Feng followed him all the way, because from the surveillance footage, Qi Sizhe would appear wherever Jiang Fei appeared.Zhu Qingyue asked someone to check Qi Sizhe's information. Qi Sizhe had a serious car accident two years ago, and the woman in the car died on the spot.Qi Sizhe went to Jiang Fei's house alone. Han Feng asked the reason again. Qi Sizhe said that he was following Li Yiqi and Jiang Fei because they were related to Yu Fei's death, and tacitly admitted that he was investigating the rough diamond case.Based on the on-site investigation and autopsy, Qi Sizhe concluded that Jiang Fei committed suicide and probably froze to death in the bathtub at home. Zhu Qingyue led people to re-inspect the scene and agreed with Qi Sizhe's judgment.

Qi Sizhe wanted to participate in the case, but Zhu Qingyue asked him to first explain the coincidences that appeared in the Jiang Fei case and the Li Yiqi case. She made it clear that she would not answer any of his questions about the case before trusting him.Qi Sizhe only said that he was fulfilling his duties as a forensic doctor and he must find out the truth.Zhu Qingyue brought Qi Sizhe to the office to participate in the discussion. There was a cut red sausage but no knife, and Jiang Fei did not have any external injuries. Judging from the luminol at the scene, Han Feng and Qi Sizhe speculated that the knife might have stabbed the murderer, so the murderer took the knife away.

There was a drop of blood left at the scene, but there was no matching record in the database.Everyone sorted out the case at the meeting. Han Fengbing was divided into two teams. One team went to check Jiang Fei's movements before drinking, and the other team went to check who Qiu Lanzi met after leaving the branch.Han Feng took Wan Guoxin to the nightclub, asked the boss to check the surveillance, and found that Zhang Lu, a girl wearing Lolita, had been in contact with Jiang Fei.Zhu Qingyue found out that Qiu Lanzi had made frequent calls to a chemical factory laboratory. In her mobile phone, there were several photos of Jiang Fei's arms.

Gao Yuan recalled that when Qiu Lanzi saw Jiang Fei's arm, he could tell at a glance that there was a fluorescent tattoo on his arm.Zhang Lu is an intern researcher at the Institute of Inorganic Chemistry, and she and Qiu Lanzi are high school classmates. Qiu Lanzi's last call was to Zhang Lu's workplace.After visiting Zhang Lu's colleagues, Han Feng learned that Zhang Lu and Qiu Lanzi had quarreled, and Qiu Lanzi took medicine because she felt unwell.Zhang Lu was taken to the police station and Han Feng interrogated her. Zhang Lu seemed shocked by Qiu Lanzi's death. She said that Qiu Lanzi told her that Jiang Fei was dead, and that Qiu Lanzi saw her name on the body.The results of Dr. Zhao's comparison came out. Han Feng asked someone to arrest Zhang Lu. Qi Sizhe looked at Zhang Lu and said that the murderer was not her and that he had arrested the wrong person.

Episode 3

Qi Sizhe stopped Han Feng. He suspected that someone had tampered with Jiang Fei's autopsy report. This person was very familiar with medical autopsy and the internal case-handling procedures of the Public Security Bureau. He even had access to case information. The only people who met these characteristics were people within the Public Security Bureau. Han Feng listened to his analysis and followed his words and said that the murderer might be one of his own.While they were talking, Zhu Qingyue listened attentively.

Qi Sizhe stood in the autopsy room, recalling the behavioral characteristics of all the forensic doctors involved in the case. When he was about to get close to the truth, the shadow of the car accident suddenly hit him and he had to give up thinking.Qi Sizhe told Zhu Qingyue and Han Feng that Jiang Fei's body showed signs of being tampered with, and Jiang Fei wrote the murderer's name on himself with invisible ink before he died, but it was erased. The black light photo taken by Qiu Lanzi was also deleted. Han Feng looked at Jiang Fei's arm, and the traces on it showed that it was Eva.Eva is the English name given to Zhang Lu by Jiang Fei. Zhang Lu said that Jiang Fei gave her money and clothes and she had no reason to kill anyone.The police found the box of cephalosporins where Zhang Lu worked, and found no problems after testing.

Monitoring from the nightclub showed that the cephalosporin in Zhang Lu's hand was the box found in the laboratory. Han Feng speculated that the murderer made Jiang Fei eat another box of cephalosporin.Gao Yuan showed Qi Sizhe the unfinished test report on the isolated drug formula, and Qi Sizhe asked about Li Yiqi's blood sample.When Han Feng and Zhu Qingyue compared the nightclub surveillance, they found someone pretending to be Zhang Lu. They learned from Gao Yuan that all the tests such as blood comparison and urine tests brought back by Jiang Fei's family were done by Dr. Zhao.

When Dr. Zhao was transferring his daughter Zhao Yiwa to another hospital, Han Feng and Zhu Qingyue arrived.After re-comparing the blood stains found in Jiang Fei's home, it was found that Dr. Zhao's blood was consistent with the blood stains found in Jiang Fei's home.Jiang Fei used to sell rough diamonds. Dr. Zhao's daughter committed suicide in the bathtub after taking it. Although she was rescued, she became a vegetative state.After Dr. Zhao heard the name Jiang Fei at the police station, he pretended to be Zhang Lu and approached Jiang Fei, drugged him, and then used his position to frame Zhang Lu.Jiang Fei stabbed Dr. Zhao, and before he died, he wrote the name Eva on his wrist with an invisible ink pen. Qiu Lanzi discovered the name, and Dr. Zhao simply killed Qiu Lanzi as well.Zhu Qingyue showed Dr. Zhao the last update in Zhao Yiwa’s space: She is a good doctor but she has no time to save me.Zhao Ewa committed suicide in the bathtub, and now Jiang Fei froze to death in the bathtub. She thought she was avenging her daughter, but Jiang Fei was not the only one who killed her daughter.

Although he had a good relationship with Qi Sizhe before, Han Feng told Zhu Qingyue that now his relationship with Qi Sizhe was that of the criminal police captain and the forensic director.Back then, Han Feng shot and killed drug master Li Ming, but Qi Sizhe insisted that the person who died was not Li Ming at all. The Yu Fei case was not investigated at all. Li Yiqi and Jiang Fei were the clues to the case that year, so he came to the branch.

At night, a girl covered in injuries knocked on the door of a house, and then, a man in black came.At the scene of the crime, Huang Hao, the owner of the pork shop, died. He had called the police to report that an injured girl ran to his house. When the police arrived, the person was already dead and there was no trace of the girl.During the investigation, there was a situation outside. Han Feng asked Qi Sizhe to stay and chased him out.

Qi Sizhe found blood stains outside and searched for them based on the traces.Han Feng chased the man in black in the woods behind the mountain. The man in black was injured. The two fought and the other said he saw the murderer.Zhu Qingyue found a cave entrance along Qi Sizhe's route and led people to follow him in. After learning about it, Han Feng also chased after him.Qi Sizhe found many hanging doll-like cocoons in the cave, but there was no cell phone signal.

The puppets were removed one by one, and Qi Sizhe cut open the cocoon, revealing what looked like animal carcasses inside.Going further inside, everyone found a huge altar-like spider web with more dolls hanging on it, including corpses.

Episode 4

A few long hairs were picked up at the pork shop and have been sent for inspection.Zhu Qingyue told Han Feng that nearby villagers said that an unregistered wild theater crew had filmed here, and the puppets were all props that were not taken away. Based on the photos sent by the crew, Qi Sizhe discovered that the crew used ordinary spider webs, but the murderer changed them into the unique funnel-shaped spider webs of the funnel spider in the drama. He suspected that the murderer was imitating the funnel spider to hunt and kill.Although the victim was injected with spider poison and strong hydrochloric acid, the real cause of death was that the murderer injected an air injection behind the victim's ear.

At the case analysis meeting, based on all known clues, the police speculated that the kidnapped girl and the doll were not the same person. The kidnapped girl should have been imprisoned in the cave first, then broke the rope and ran out to the pork shop to seek help. Later, she was discovered by the murderer, who killed the boss and abducted the girl.As for the deceased, her name is Ye Yingying, 25 years old, a public relations officer for a marketing company. She has been missing for almost a month. During this period, there were no blackmail calls and no money was lost.Qi Sizhe determined that the internal organs inside the doll were from cattle, and the murderer most likely had a medical background.Zhu Qingyue profiled the murderer as having psychological problems and a certain sense of ritual, and the puppet should be the murderer's practice.

Based on the traces of the body being tied up and the calendar found in the cave, Qi Sizhe speculated that if the murderer was really imitating spiders to kill, then his imprisonment logic and crime cycle should have a fixed pattern.There are less than three days left and time is very tight.Han Feng ordered to go down, Li Xiaoxi went to investigate nearby surveillance videos, Wan Guoxin went to visit witnesses, and Su Huaining went to investigate Ye Yingying's colleagues and family members.There were no clues in the surveillance. Su Huaining found out that Ye Yingying liked medical beauty. Qi Sizhe determined that the internal organs in the doll were the internal organs of a sick cow suspected of bovine tuberculosis.Wan Guoxin received news that someone had reported missing, and according to the description, he matched the victim in the case.

Han Feng and Su Huaining went to the police station, and the reporter provided the WeChat records of them and their daughter Xie Yaoqi.According to the investigation, only the Agricultural University was doing research on bovine tuberculosis, so Qi Sizhe and Zhu Qingyue went to the school.Professor Wang told them that they had indeed conducted an experiment a month and a half ago, but the samples had been treated harmlessly. Qi Sizhe took tissue slices to Professor Wang, and Zhu Qingyue asked him to provide a list of students who participated in the experiment.

The reporter said that Xie Yaoqi was afraid of spiders. Han Feng met Xie Yaoqi's colleague Li Shuting in the courtyard of the police station. Li Shuting said that Xie Yaoqi had been fired. She worked part-time in a medical aesthetics clinic and used all the money she earned to do medical aesthetics.Professor Wang's comparison results showed that the internal organs inside the doll came from their experiment. Li Xiaoxi gathered all the students who participated in the experiment to the police station, and everyone conducted inquiries one by one.

Han Feng and Su Huaining went to the black clinic that Xie Yaoqi mentioned. The clinic was a masseur but secretly did medical beauty.Han Feng took out a photo of Xie Yaoqi. The boss, Liao Dong, said that she worked part-time as a nurse here. Han Feng also took out a photo of Ye Yingying. Liao Dong said that she was allergic to drugs when she came for medical beauty treatment, so he called his nephew, who was studying veterinary medicine at the Agricultural University, to help.Zhu Qingyue checked that there was indeed a student named Liao, and Han Feng asked her to arrest him immediately.There is a funnel-shaped spider web in Liao Yunsheng's residence, with many spiders hanging there, but no funnel spiders.

There were many portraits at the scene, including those of Ye Yingying, Xie Yaoqi, and one of an unknown girl. Han Feng saw that it looked like Li Shuting, so he called Li Shuting, and Li Shuting's phone rang on the spider web.

Episode 5

After identification by the identification department, the pattern of the soles and the soil on the shoes found at Liao Yunsheng's home were consistent with what the police found in the Bat Cave. In addition, Liao Yunsheng had participated in the bovine tuberculosis experiment, and the police determined that he had been to the crime scene. Now Liao Yunsheng is the biggest suspect.The hair found in the pork shop belonged to Xie Yaoqi, and the phone that rang at Liao Yunsheng's residence belonged to Li Shuting. Han Feng initially suspected that Liao Yunsheng had tied up Xie Yaoqi and Li Shuting after killing Ye Yingying.Qi Sizhe identified the residue in the syringe found at Liao Yunsheng's home as funnelweed, which was the same as that found in Ye Yingying's body.

Han Feng and the others went to look for clues separately. Qi Sizhe went to see his senior fellow psychiatrist Chen Chuchuan. Chen Chuchuan told Qi Sizhe that there is a mental illness called lycanthropy. When the disease occurs, one will imagine oneself as an animal or insect. The cause of the disease is very complicated, and it may be the family of origin, excessive medication or drugs.Qi Sizhe looked through the books and information in Liao Yunsheng's greenhouse, which talked about the habits of funnel spiders. Judging from the 13 days on the desk calendar, it should be the time from mating to laying eggs for funnel spiders, so he tied the victim into the shape of an egg.

I learned from pet dealers that if the funnel spider’s original living environment is destroyed, it will find a new place to weave its web.Based on the suspect's behavioral logic, Han Feng told Zhu Qingyue that Qi Sizhe once said that female spiders kill male spiders after mating, so the victim is not prey but an egg.The alarm platform once received a call, probably from Li Shuting. Han Feng went to listen to the recording. When he was at a loss, Qi Sizhe came. He proposed to search the cave and the vicinity of Liao Yunsheng's home. Han Feng made arrangements, asked the regional police stations for assistance, and then drove out with Qi Sizhe.Li Xiaoxi found a suspicious person from the surveillance camera, located near the abandoned factory that Qi Sizhe and others judged, so Han Feng drove over.

After arriving at the abandoned factory, Han Feng and Zhu Qingyue split up, while Su Huaining and Qi Sizhe searched separately.Qi Sizhe was attacked by a man in black. Han Feng rushed over and the man in black escaped. After chasing him, Han Feng found Li Shuting who was about to suffocate with her head wrapped in plastic wrap.Li Shuting confessed to the police that Xie Yaoqi was in a relationship with Liao Yunsheng. She wanted to go to Liao Yunsheng's house to find Xie Yaoqi, but she was knocked unconscious and moved to an abandoned factory.Li Shuting said that she didn't see the other person's face clearly, but she knew that the other person thought she was a spider, so she wrapped the plastic wrap around her.Qi Sizhe always felt that something was wrong. According to the current clues, it was unreasonable for the murderer to change his behavior and arrest Li Shuting, or there might be some special reason.After hearing this, Han Feng took Qi Sizhe back to the abandoned factory again.

There were funnel spider webs specially made by the murderer in the first two scenes, but not in the abandoned factory. Qi Sizhe couldn't figure it out, and Han Feng also thought it was unreasonable.If the murderer changed his behavioral logic, he would kill Xie Yaoqi early, and the time left would be getting less and less.Chen Chuchuan was driving and encountered a check-in. When he returned, he heard from the front desk that a patient had imagined that he was a spider, but he left before registering. He told Qi Sizhe about this.The surveillance video was not clear, and the front desk could not clearly see what the other person looked like.

After checking all the surveillance cameras where the suspect passed by, the police targeted the community near the elevated highway.The police station in the area contacted the neighborhood committee, and together with the water and electricity bill collected from the greenhouse, Han Feng and the others quickly found the suspect's residence. There was no one inside. There were cow pathology books on the coffee table. There was a human cocoon in the back room, which was Liao Yunsheng.

Episode 6

Now that Liao Yunsheng is dead, Liao Dong has become the only person who has interacted with the characters in the case.Although Liao Dong's alibi had been verified on the day of the incident at the pork shop, Han Feng still suggested calling him over for questioning.Liao Dong reported that Xie Yaoqi met Ye Yingying after working part-time at his place, and Li Shuting was brought here by Xie Yaoqi. After they met, they had a good relationship and talked and laughed. However, Liao Yunsheng only went to the clinic during holidays and when he received calls from him. Later, Liao Dong discovered that Liao Yunsheng secretly liked Xie Yaoqi, but he had hardly spoken to the other two girls.One time when all three girls were in the clinic, Liao Yunsheng came suddenly. He and Xie Yaoqi and Ye Yingying both smiled and greeted each other, but when they faced Li Shuting, their expressions were very unnatural. After that, Li Shuting never went to the clinic again.

Qi Sizhe told Han Feng and Zhu Qingyue that Liao Yunsheng was the first victim.The cause of death of Liao Yunsheng and Ye Yingying was the same, and they had been dead for at least four weeks.It was discovered that the house where Liao Yunsheng lived belonged to Chen Hua, Liao Yunsheng's classmate. Chen Hua had been abroad for a long time.The vegetable shed belonged to Zhao Si, a nearby villager. He had been injured in a fall and had been lying at home for more than a month and had no idea about the vegetable shed.The murderer's behavior pattern has changed since the Li Shuting case, and the crime cycle has also been shortened. Qi Sizhe is very surprised.Han Feng gave another idea. When Xie Yaoqi was kidnapped, the police station received a call to report the crime, but the pork shop owner died and no one could prove that Xie Yaoqi was kidnapped. If Xie Yaoqi was the murderer, then everything would make sense. After she committed the murder, she led all the clues to Liao Yunsheng.Gao Yuan told everyone that Xie Yaoqi's DNA was detected at the scene of Liao Yunsheng's death.

If Xie Yaoqi is the murderer, then there is something wrong with Li Shuting's words.Han Feng took people to find Li Shuting, but found that the accommodation provided by Li Shuting was wrong.Qi Sizhe told Han Feng and Zhu Qingyue that Li Shuting had been misleading them.Han Feng recalled that when he first came into contact with Li Shuting, Li Shuting was guiding them, and the clinic was also the clue provided by Li Shuting.Wan Guoxin once again investigated the school and found that Li Shuting used Wang Qilong's fake identity to participate in the school's bovine tuberculosis experiment. During this period, Li Shuting went to the men's room and was met by Liao Yunsheng, so Liao Yunsheng reacted greatly when he saw Li Shuting dressed as a woman in the clinic.Zhu Qingyue found the real Wang Qilong, and Wang Qilong said that Li Shuting took the class for him.Han Feng saw that Wang Qilong cared about Li Shuting, so he showed Wang Qilong the photo of the victim. Wang Qilong became emotional and said he didn't know anything.

Li Shuting pushed the tied Xie Yaoqi to the ground and loudly said that no one liked her, no matter how beautiful she became, no one liked her.It turned out that when Xie Yaoqi, Ye Yingying and Li Shuting were in the clinic together, a spider crawled on Ye Yingying's body. She was so frightened that she trampled it to the ground and died. She said that she couldn't eat after seeing this ugly and fluffy monster. Xie Yaoqi also agreed that spiders should not exist in this world.Li Shuting took her place.

Wang Qilong still refused to speak, and his family found nothing. Now the clues to the case have been lost again.Qi Sizhe was inspired by Han Feng's words. He speculated that Li Shuting's killing of Liao Yunsheng was imitating a female spider killing a male spider. The failure to lay eggs may be because she was unable to do so. Judging from the destruction of the victim's uterus, the murderer should have a tendency to vendetta against women.Han Feng recalled that when he first met Li Shuting, Li Shuting's bag was full of medicines, one of which was to maintain the ovaries and treat irregular menstruation. Han Feng boldly guessed that maybe Li Shuting was not a woman at all.

Wang Qilong finally spoke. Li Shuting's real name is Li Shujun. She is a hermaphrodite. They have known each other since they were children and they were both orphans.When he was eight years old, Li Shujun changed his name to Li Shuting and started his life again. Wang Qilong wanted Li Shujun to be happy, so he kept helping him hide his identity.Li Shuting once heard Liao Yunsheng tell Xie Yaoqi and Ye Yingying about meeting him in the men's room, which made him completely emotionally collapsed. Just when he was about to cut his wrists and commit suicide, he saw a spider crawling over. He felt that he was saved by the spider.Li Shuting told Xie Yaoqi that anyone who laughed at him should die.

Episode 7

According to the clues provided by Wang Qilong, Zhu Qingyue, Han Feng and the others found Xie Yaoqi in time. Xie Yaoqi had been put into a drug habit and needed to be released immediately.Qi Sizhe urgently injected Xie Yaoqi with medicine. After Han Feng heard the noise, he chased Li Shuting. Li Shuting had hallucinations and ran with the shadow of a spider. Finally, she stopped on a road, raised her palms and looked at the street lights and cried and laughed. In the end, she was hit by a speeding car and died on the spot. Everyone stood there in shock at the sudden accident.

Xie Yaoqi was out of danger. Wang Qilong was taken to the morgue. The moment he saw Li Shuting's face, Wang Qilong's breathing almost stopped.Qi Sizhe asked Han Feng whether Li Yiqi had a phototactic reaction when he was on the rooftop. Han Feng told him not to guess. Qi Sizhe said that Yu Fei also had a phototactic reaction in the car. Han Feng yelled that the case was closed and Li Ming had been killed. He did not want to mention Yu Fei again. Qi Sizhe told him that although he was the adopted son of the Yu family, Yu Fei had always regarded him as her brother.

Li Shuting's blood test report came out, and common drugs were still not detected.Qi Sizhe wanted to retest the drugs found in Li Shuting's home. He wanted to know whether Li Shuting's hallucinations were caused by the drugs. Gao Yuan showed the drug test report to Qi Sizhe and said that nothing special was found, and that generally anti-manic depression drugs do not cause hallucinations.Qi Sizhe found a mark on a medicine bottle that Gao Yuan had not seen before.

Han Feng came to Qi Sizhe. He felt that Li Shuting and Li Yiqi were in a similar state of hallucinations, but even if the same new drug could be found in their bodies, it could not be compared with the Uncut Diamond case.Qi Sizhe made it clear that even if there was only a glimmer of hope, he would not give up on tracing the truth about Yu Fei's death.

Han Feng asked Team Guan, who had been banned together with him, to inquire about the rough diamonds. He told Team Guan that Qi Sizhe guessed that someone was researching new drugs based on rough diamonds, or conducting secret experiments on a specific group of people. These victims all showed the same phototaxis as Yu Fei before she died.

The case of Liu Yuanyuan's disappearance was transferred to the Criminal Police Team. Liu Yuanyuan once insisted that her mother was murdered. Later, Liu Yuanyuan also disappeared mysteriously, and her friend called the police.According to interviews, Liu Yuanyuan studied very well in high school. She could have gone to medical university but did not continue due to some reasons. She has been living with her seriously ill mother. At work, Liu Yuanyuan is good and serious.The police station transferred the case because Liu Yuanyuan bought a knife before she disappeared.

Human bones were found near the railway, and the police were dispatched. The railway police said they found a figure who seemed to be a woman during their patrol.Test results of the unknown powder on the bones showed that it was phenolic resin, which is resistant to high temperatures and is often used to stick emery to grinding wheels.An expanded search found no other bones.Zhu Qingyue and Han Feng proposed to follow up the two cases together.Li Xiaoxi discovered that Liu Yuanyuan had bought oxalic acid and hydrochloric acid, and Gao Yuan and the others had smelled a pungent smell on the bones.

Qi Sizhe told everyone the test results. The pelvis came from a woman over forty-five years old. Unlike an old corpse, no valid DNA could be extracted from the bones. This requires further investigation.Wan Guoxin also synchronized the case of Liu Yuanyuan’s disappearance.

New bones were found, hands and feet.Witnesses said they saw the person throwing the bones, but it was too dark to see what he looked like.The pieces of clothing at the scene were very similar to Liu Yuanyuan's clothes in the surveillance camera and needed to be taken back for testing.Then, bags of human bones were found in many places.Qi Sizhe and Gao Yuan pieced the bones together bit by bit, and found that they didn't look like the bones of one person, but seemed to belong to multiple victims.

Episode 8

Qi Sizhe asked Chen Chuchuan why he came to Hecheng to open a clinic. Chen Chuchuan asked him in return. Qi Sizhe did not hide it. Chen Chuchuan said that he was our friend after all.At that time, the scene of the three drinking together was still vivid in his mind. Qi Sizhe could not forgive Li Ming. If he really regarded them as friends, he would not do such a thing.Chen Chuchuan said that it was all personal choice, and Qi Sizhe couldn't live with it. After all, Li Ming killed Yu Fei.

Gao Yuan showed Qi Sizhe the results of the comparison of the drug ingredients in Li Yiqi and Li Shuting's bodies. The comparison of the drug ingredients in the two people's bodies did not match.Han Feng looked at Li Yiqi, who was still unconscious, with mixed emotions. Qi Sizhe told him the result.Chen Chuchuan and Qi Sizhe went to celebrate the birthday of their teacher Wu Yongchang. There was a photo of the three of them in Wu Yongchang's home. Qi Sizhe asked Wu Yongchang if the drug formula prepared by Li Ming had been leaked. Wu Yongchang strongly supported Qi Sizhe to investigate and find out the matter.

Qi Sizhe took Han Feng to the forensic autopsy room. The bones collected so far came from at least ten people, but DNA could not be extracted. The DNA found on the clothing fibers found at the scene was Liu Yuanyuan's.

The identity of the deceased cannot be confirmed without extracting DNA. Although Liu Yuanyuan purchased powerful solvents and knives, Qi Sizhe analyzed the bones and the murderer's method of disposing of the corpse was very advanced. Liu Yuanyuan did not have any relevant knowledge. It was impossible for Liu Yuanyuan to decompose ten people by herself in four or five days.Zhu Qingyue and Han Feng also felt that Liu Yuanyuan was not the murderer at all.Judging from the locations where the bodies were dumped, they were all surveillance blind spots. Wan Guoxin believes that the murderer chose them after careful thinking and judgment.The top priority now is to find Liu Yuanyuan. The surveillance shows that Liu Yuanyuan was last seen four days ago wearing a red coat and carrying a satchel. At the end of the surveillance is an alley. There is a night market behind the alley. There are no surveillance cameras and there are many exits to the night market. It is too difficult to find Liu Yuanyuan's last image information. Zhu Qingyue put forward a point of view, maybe Liu Yuanyuan did not leave the night market at all.

Director Bai Nian set up a task force and asked Qi Sizhe to join in to assist.Han Feng and Su Huaining found out that a Sanbengzi had pulled Liu Yuanyuan, so they asked the Sanbengzi to take them to the place where Liu Yuanyuan went at that time, Hecheng Medical University.

According to the school surveillance, Liu Yuanyuan's last traces were found. She went to the direction of several buildings that were being renovated that the school did not monitor.While Qi Sizhe and Gao Yuan were eating, Han Feng and Su Huaining also came.Qi Sizhe was inspired by Gao Yuan's words. He believed that the bones collected might not be human bones at all, but specimens soaked in formalin, so no DNA could be extracted.

Han Feng and the others went to the Medical University together. The security office received them and said they had never seen Liu Yuanyuan after seeing her photo.Han Feng and Qi Sizhe went to the specimen building, while Zhu Qingyue and the others were exploring the surrounding area.All specimens in the herbarium, including all five specimens, are present, match the records, and were most recently returned a year ago.Qi Sizhe found signs that the specimen jar had been moved, so Han Feng called someone from the technical room.The man from the security office usually lies on the bed in the security room. Because there are usually no people around, and students usually have professor approval when borrowing, he is a little lazy.

Qi Sizhe confirmed that the murderer first killed and dismembered the body and then replaced it with the body parts and specimens in the herbarium. After disposing of the specimens and body parts, the remains were left and discarded in various places. The incisions on the body parts were very smooth, and all the cuts were made at the bone seams. Qi Sizhe deduced that the murderer had a good understanding of the human body structure.There was no match between the DNA of the missing person and the body parts. Gao Yuan found that the deceased had arthritis. Qi Sizhe thought of Liu Yuanyuan, so after comparison, he found that the body parts belonged to Liu Yuanyuan.

Episode 9

Qi Sizhe speculated that the specimen room was probably the first scene. According to this idea, the opened iron mesh Zhu Qingyue found in the back mountain was most likely the place where the murderer fled the scene.Wan Guoxin led people to search for heads in the back mountains.Qi Sizhe and the others went to the specimen room.A lot of blood stains were detected on the floor of the specimen room, extending to the specimen shelf. Han Feng and the others moved the shelf and discovered that there was a secret room behind the specimen shelf.

In the room, in addition to the brain specimen, there was also a notebook. Zhu Qingyue flipped through it and found that the preparation of the head specimen was recorded in it. Huang Zhengming's name was written on the lower right corner of the title page.Qi Sizhe checked the mop and bucket. There was a reaction after the luminol reagent was sprayed. Qi Sizhe told Han Feng that this was probably the first scene of dismemberment.The school leader told Han Feng and the others that the two rooms used to be connected, but later they became empty, and the room on the left was turned into a specimen room. He didn't know anyone else was using that laboratory. Maybe Professor Huang Zhengming was assigned a key when he moved to the new building, so he was using it secretly. Professor Huang Zhengming, an old expert in brain nerves and anatomy, was known as Huang Yidao.

Han Feng and Zhu Qingyue went to check Huang Zhengming's office. Han Feng found a takeaway. The name of the restaurant on it was Spring Restaurant, which was where Liu Yuanyuan worked.After testing, Qi Sizhe found that what was found in the room was not Liu Yuanyuan's head.Huang Zhengming was taken back to the police station. He admitted to using school resources to conduct experiments, but firmly denied murder and dismemberment. He said that the laboratory next to the specimen room was not his, and he only used it for his experiments.

Han Feng took out the takeout order, and Huang Zhengming said that he didn't want it to be troublesome, so he chose a restaurant to deliver the food. Since he always asked the clerk to leave it outside the door, he still has no idea who delivered it.Qi Sizhe sent a message to Zhu Qingyue and explained in detail that the research Huang Zhengming was doing required a large amount of experimental data. Huang Zhengming said without hesitation that as long as his experiment could succeed, he was willing to kill people, but asked the police to provide evidence.

After Han Feng and the others left the interrogation room, Huang Zhengming looked at the lamp above his head, his hands still shaking. Qi Sizhe looked at Huang Zhengming's watch and remembered that he had seen Li Ming wear it before. He told Han Feng the situation, but Han Feng still didn't believe it.

The police found six heads in the woods behind the mountain. Huang Zhengming gave an explanation. Some were obtained through the donation center through personal relationships, and some were removed from unwanted human specimens at the Medical University.Li Xiaoxi made a new discovery. Gao Yuan confirmed that the hammer wound on Liu Yuanyuan's head was a fatal injury. Qi Sizhe concluded that the time of death was between 2 and 6 pm five days ago. He said that judging from the skull, Huang Zhengming did not use Liu Yuanyuan's head for brain research.The handwriting of the donor list provided by Huang Zhengming is very close to the handwriting in the second half of the notebook, but completely different from the handwriting in the first half of the notebook. Qi Sizhe said that both handwritings are Huang Zhengming's because he has Parkinson's disease, and Liu Yuanyuan's head incision is very smooth, which is not what Huang Zhengming can do.Wan Guoxin checked Huang Zhengming's social connections and ruled out the possibility of someone helping him kill.

Qi Sizhe stopped Huang Zhengming and asked him if the watch belonged to Li Ming. Huang Zhengming was very irritable and refused to answer his questions at all.According to interviews and investigations, the three suspected professors all have alibis.After reorganizing the case, everyone found that after Liu Yuanyuan brought so many things to the Medical University, they disappeared. Moreover, Liu Yuanyuan's friends once said that she could have attended the Medical University.

Li Xiaoxi told Han Feng that Gao Huilan and the students pushed a corpse bed and left the specimen building. The students were very afraid of corpses. He and Li Xiaoxi went to investigate what happened.On the other hand, Zhu Qingyue and Wan Guoxin went to visit Liu Yuanyuan’s school and the invigilator.The invigilator was very impressed and said that Liu Yuanyuan looked very much like one of her students, Ding Youmei.After checking, it was discovered that Ding Youmei worked as an assistant professor at the Medical University and was Gao Huilan's daughter.

Back then, Yu Fei became a forensic doctor with the help of Qi Sizhe. He had always felt guilty. He swore in front of Yu Fei's grave that he would find out the truth and give her an explanation.

Episode 10

Liu Yuanyuan and Ding Youmei looked almost exactly the same. Zhu Qingyue suspected that Liu Yuanyuan took the exam for Ding Youmei.Judging from the school's surveillance, Liu Yuanyuan left fifteen minutes after entering Gao Huilan's laboratory. She deliberately covered her face when leaving and had a plastic bag in her hand.Wan Guoxin found Gao Huilan's remittance records to Liu Yuanyuan. Because the passbook was registered in her mother's name, it had not been found before. The earliest one was eleven years ago, and Liu Yuanyuan's college entrance examination and Ding Youmei's TOEFL exam were at the same time. In addition, Gao Huilan also sent a large sum of money to Luan Fang, a classmate in the same examination room as Ding Youmei.

Ding Youmei admitted that Liu Yuanyuan took the exam for her and said it was all arranged by Gao Huilan.Gao Huilan said that she performed a free operation on Liu Yuanyuan's mother, but Liu Yuanyuan kept threatening her with taking a substitute exam. After her mother died, Liu Yuanyuan came to the laboratory to find her, and the two had a quarrel.Liu Yuanyuan took a knife to kill Gao Huilan. Ding Youmei heard this and pulled away from Liu Yuanyuan. Liu Yuanyuan broke down and cried. Gao Huilan comforted Liu Yuanyuan for a while, and then Liu Yuanyuan left on her own.Zhu Qingyue showed Ding Youmei the surveillance photos, and Ding Youmei said it was Liu Yuanyuan without thinking.

There is currently no evidence that Liu Yuanyuan's death is related to Gao Huilan Ding Yumei. Liu Yuanyuan left the building and left the school. The video was very blurry and it was not clear who it was.Han Feng boldly speculated that if Ding Youmei pretended to be Liu Yuanyuan and left the building and lost her head, and then returned to the experimental building through the iron fence, she could avoid the surveillance at the school gate and return to the school. However, it is still unclear how she avoided the surveillance in the building.

Qi Sizhe found a little fiber and human tissue in the cracks of the bulk freezer in the specimen room, which were not bulk specimens.When discussing the case, Qi Sizhe told Han Feng and Zhu Qingyue that generally when schools need to use cadavers, they will hold classes in the anatomy room and will not move the cadavers around. Moreover, the cadavers are packed in body bags when transporting them, which is the best cover.Gao Yuan tested the fibers and human tissue and found that the fibers came from Liu Yuanyuan's coat, and the human tissue belonged to Ding Youmei, indicating that Ding Youmei wore Liu Yuanyuan's coat. Gao Huilan was lying, and Liu Yuanyuan did not walk out of her laboratory alive at all.

The police went to extract Ding Youmei's blood for comparison. Qi Sizhe and the others went to inspect Gao Huilan's laboratory, which contained a large amount of Liu Yuanyuan's blood. In the corpse cabinet, Ding Youmei's DNA was found, and Gao Huilan admitted that she had done everything.That year, when Gao Huilan saw Liu Yuanyuan for the first time in the hospital, she thought it was her daughter Ding Youmei.Ding Youmei's academic performance was very poor, and her father was very dissatisfied. Gao Huilan approached Liu Yuanyuan and offered to take the exam for her mother in exchange for surgery.

Gao Huilan thought Liu Yuanyuan was a good child. When she learned that her mother's illness had recurred, she went to Liu Yuanyuan's mother and bluntly stated that she was Liu Yuanyuan's burden and a bottomless pit. Originally, Liu Yuanyuan could have been admitted to a medical university and live a better life, but now she has been dragging her down and has to pay off the huge debt she owed.Liu Yuanyuan's mother was ill. She grabbed Gao Huilan's clothes and pointed at the medicine on the cabinet. Gao Huilan threw the medicine away and watched her move little by little.Later, Liu Yuanyuan came to Gao Huilan and took out the buttons that her mother had torn off Gao Huilan. Gao Huilan was dumbfounded when she saw it, so Liu Yuanyuan stabbed Ding Youmei with a knife. Gao Huilan picked up a hammer and knocked Liu Yuanyuan. After that, Gao Huilan asked Ding Youmei to put on Liu Yuanyuan's clothes.

There are fingerprints of Liu Yuanyuan's mother, Liu Yuanyuan and Gao Huilan on the button.Zhu Qingyue told Ding Youmei that Gao Huilan had confessed everything and admitted to killing Liu Yuanyuan. Ding Youmei cried and asked what would happen to her mother. Zhu Qingyue said that Gao Huilan would be handed over to the judiciary for prosecution for intentional homicide. Ding Youmei blamed herself after hearing this. It was all her fault. Zhu Qingyue told her that she was suspected of harboring but would be sentenced, and then left the interrogation room. Ding Youmei actually cried and laughed after Zhu Qingyue went out.

Episode 11

Qi Sizhe secretly went to Huang Zhengming's office and found a research paper on the pupillary light reflex area and the pretectal area of the midbrain. He took the paper to find Huang Zhengming. Huang Zhengming got emotional and yelled that he wanted to accuse him of breaking into a private house. Before Qi Sizhe could ask about his relationship with Li Ming, Huang Zhengming fainted.Director Bai Nian received Huang Zhengming's report and the neighbor's evidence, so he could only suspend Qi Sizhe.

Zhu Qingyue and Wan Guoxin interrogated Ding Youmei again. Ding Youmei's private life was so explosive that her disguise as a good girl was torn apart, and she simply stopped pretending.Wan Guoxin showed her a photo of herself and a boy, and pointed out that the buttons Liu Yuanyuan's mother pulled off came from her coat. Ding Youmei was a little panicked, stressing that there were so many clothes on the market, and her mother had already confessed.Zhu Qingyue looked at her and refused to recognize her, so he went out and took a mobile phone, saying that Liu Yuanyuan's mother had bought Liu Yuanyuan a doll with a pinhole camera inside, and showed the mobile phone to Ding Youmei. Ding Youmei's psychological defense suddenlyShe collapsed. She couldn't stand that Gao Huilan kept giving money to Liu Yuanyuan and her daughter. She felt that all the money in the family should belong to her after her father died, so she went to find Liu Yuanyuan's mother and watched her die in front of her.

Later, Liu Yuanyuan took the button to Ding Youmei. Ding Youmei said that she was helping her get rid of her and her mother's life, and threatened her not to ask Gao Huilan for money again.Seeing that Ding Youmei was so frantic, Liu Yuanyuan took a knife to kill her, but Ding Youmei pointed the knife at herself. Gao Huilan came in and saw Ding Youmei and pushed Ding Youmei aside, only to learn that her daughter had killed someone.Gao Huilan knelt down in front of Liu Yuanyuan and begged her not to tell the story, and promised to use all his money to make up for her and take care of her. Ding Youmei became even more angry after hearing this. She picked up a hammer nearby and hit Liu Yuanyuan's head, then opened Liu Yuanyuan's hand and took away the button. After that, she looked at Gao Huilan, you will protect me, right?

Everyone had dinner together, and Zhu Qingyue told Qi Sizhe that Han Feng had begged Bai Ju and wanted to be punished together with Qi Sizhe.When going to see Yu Fei, Qi Sizhe found a few bags of nuts on the tombstone. After a while, Han Feng appeared. Qi Sizhe talked about begging for mercy. Han Feng told him that Huang Zhengming had been eliminated when solving the rough diamond case, and Huang Zhengming's watch was indeed given by Li Ming.

At night, a fire alarm broke out in the hospital and everyone ran out. A man in a white coat sneaked into Li Yiqi's ward and injected him with medicine.Despite the doctors' best efforts to rescue him, Li Yiqi died.The suspect's whereabouts were traced, and a falling case coincidentally occurred in the community he entered.The suspect's car was found at a construction site near the community, but it was completely burned.

The girl who fell from the building was named Zhai Xixi, and she was mute. Her father, Zhai Shanjun, said that there was no one at home when he returned home. Later, he ran downstairs with his neighbor and found that his daughter had fallen to her death.As soon as Zhai Xixi's younger brother Xiaoshan returned home, he rushed to Zhai Shanjun and yelled that he had killed his sister. As a result, he suffered a heart attack and fainted due to excessive emotion.

Judging from the situation at the scene, Zhai Xixi probably did not jump off the building on his own initiative.When checking the house downstairs, Qi Sizhe found that the clothes drying rod on the balcony was bent, and Zhai Xixi had bruises on his left ankle, so he concluded that Zhai Xixi committed suicide.

Episode 12

Xiaoshan's condition is very complicated. Although it is not life-threatening for the time being, it will be difficult to survive if he does not undergo surgery quickly. The doctor told Zhu Qingyue that his family members also knew about this situation.Li Xiaoxi investigated that Zhai Shanjun's financial situation was not good and he had been relying on the insurance compensation of his wife Jiang Meiqi who died in an accident. Just three months ago, Zhai Xixi took out an accident insurance of 3 million, and the beneficiary was Zhai Xiaoshan.

Zhai Shanjun told Zhu Qingyue that a few years ago, when he was playing outside with his family, he was attacked by a group of desperadoes. Jiang Meiqi was stabbed to death and he was injured. Zhai Xixi lost his voice and never spoke again. Zhai Xiaoshan resented him and thought it was all his fault.Regarding accident insurance, Zhai Shanjun said he did not know anything about it.

Qi Sizhe was certain that Zhai Xixi did not commit suicide. The on-site investigation could prove that there were other people present when Zhai Xixi fell from the building, and that the body may have been touched.The house downstairs of Zhai Xixi's house had been opened recently, but the agent confirmed that he had not been to that house recently.According to reasoning, Zhai Xixi's left shoe was taken away by the murderer, and then he went to Zhai Xixi's house, took the right shoe of the same model, and left the left shoe of the same model on the balcony of Zhai Xixi's house.In this way, it is very likely that the door was open when Zhai Shanjun went downstairs, giving the murderer a chance to change his shoes.

Han Feng and Wan Guoxin went to the real estate agency. The real estate agency confirmed that no one had visited the house recently, the keys had never been touched, and the store was monitored.Qi Sizhe told Han Feng that when Zhai Xixi fell from the building, witnesses said there were constant flashes of light downstairs opposite. Although Zhai Xixi did not have any drug reaction in his body, Qi Sizhe also believed that it could not be concluded that there was no connection between the two.Qi Sizhe conducted a simulation experiment: If the two were connected, the flash of light downstairs opposite also became a signal to guide Zhai Xixi to jump off the building. However, after Zhai Xixi jumped, she was accidentally hung on the clothes drying pole in 601, the sixth floor, downstairs of her home. In order to ensure that she would succeed in committing suicide, the murderer had to run upstairs to help, using the stairs to avoid surveillance.

After Zhai Xixi fell, the news spread immediately. The murderer took his left shoe and went to Zhai Xixi's home to change the shoes. Then when he ran down, he met the troubled teenagers. Because he was afraid of being seen, he turned to escape upstairs. But by chance, a neighbor came out of the elevator to Zhai Xixi's house, so he was trapped between the stairs on the seventh and sixth floors. According to this inference, everyone found Zhai Xixi's lost shoes in the refrigerator in room 1006 upstairs.

Now the real estate agent was under serious suspicion. In order not to alert the snake, Li Xiaoxi pretended to be a tenant and wanted to see house 1006. Sure enough, Zhang Chunmin from the real estate agent went to the house to pack things in advance and was caught by Wan Guoxin.Zhang Chunmin strongly denied that he was related to Zhai Xixi's case. He secretly assigned the key and now lives in 1006.Qi Sizhe compared the fingerprints, but Zhang Chunmin's did not match the fingerprints on the shoes.

Zhang Chunmin said that he once lent 1006 to fellow villager Wang Chen, who was the broker of Zhai Xixi Insurance Company.Han Feng interrogated Wang Chen. Wang Chen said that he and Zhai Xixi became friends during business exchanges. Entering 1006 was purely a coincidence. When he went to return Zhang Chunmin's key on the day of the incident, he saw Zhai Xixi jumping down. HeAfraid of irritating Zhai Xixi by shouting, he hurriedly ran upstairs. As a result, Zhai Xixi still fell down and got stuck on the clothes drying pole in 601, so he entered the room to save Zhai Xixi, but Zhai Xixi untied his left shoe by himself.In order to prevent Zhai Xixi's death from being in vain and to get rid of his own suspicion, Wang Chen changed his shoes and hid them in House 1006.

Wang Chen's fingerprints were compared with the fingerprints on the shoes, but the blood stains on the shoelaces only belonged to Zhai Xixi.Han Feng felt that Wang Chen was lying. Wang Chen only admitted that there were flaws in his business and helped Zhai Xixi to defraud insurance companies.Gao Yuan conducted a pharmacological analysis on the medicine in a medicine bottle at Zhai Xixi's home. It was the same as Li Shuting's anti-manic depression medicine, and the bottle had similar imprints.

Episode 13

Qi Sizhe showed the imprint of the medicine bottle to Chen Chuchuan and said that he suspected that someone was developing drugs to make poison.Chen Chuchuan advised Qi Sizhe not to dwell on the past. Now that the result has been achieved, let it pass and don't keep it stuck in his heart.

Li Xiaoxi checked Zhai Xixi's chat software and restored a deleted QQ group chat record.The insurance company told Han Feng that Wang Chen had been suspended for investigation.Zhu Qingyue went to Zhu Xiaoshan and made it clear that Zhai Shanjun was not the murderer.Zhu Xiaoshan knew about that QQ group and said that it was full of people who had thoughts of committing suicide. He had also joined it before. Zhai Xixi was introduced to it because of his introduction. There was an elder sister Liu Qing who was a volunteer in the hospital who was responsible for educating them.Following this clue, Zhu Qingyue and Han Feng visited Liu Qing in the coffee shop and experienced the exchange meeting organized by Liu Qing. Shop assistant Xiao Lin was also in the group. She said that today was the last time she came here because she had found the light in despair.Han Feng found a picture album, which was full of photos of Mandala, and there were signatures underneath.

Su Huaining found out that Wang Chen had a customer a year ago, Song Qian, the daughter of Song Weimin, the owner of the restaurant where they often went to eat.Han Feng went to Song Weimin's hotel, which was closed. At the same time, Song Weimin drove Wang Chen to the lake in a taxi.

Early the next morning, a taxi was found sunk in the lake. After it was salvaged, Wang Chen was sitting in the driver's seat and Song Weimin was in the back seat.

Qi Sizhe performed an autopsy and found that Song Weimin had bruises on his neck, which were consistent with the safety belt. It was speculated that he had died before falling into the water. It was judged that he was strangled to death by Wang Chen with a safety belt. In this case, Song Weimin was probably strangled in the driver's seat and put in the back seat before the car sank into the lake.The owner of the car was a friend of Song Weimin and had an alibi at the time of the crime.Song Weimin had terminal kidney cancer, and Song Qian also died accidentally after falling from a building a year ago. The amount of the claim was also three million, and the person in charge was Wang Chen.

Han Feng found tire marks artificially covered up by the lake. He told Qi Sizhe that there was a third person at the scene and Wang Chen's death was not an accident.Qi Sizhe and Li Xiaoxi checked Wang Chen's phone records and found that a phone number called Wang Chen after Li Yiqi died. Wang Chen also called a phone number before his death. Now the two numbers match and have been canceled.

Wang Chen found a three million insurance policy in the box, and the policy holder was Xiao Lin.At night, Xiao Lin went up to the rooftop alone and looked at the lights opposite.After Qi Sizhe arrived, he followed Xiao Lin's gaze and saw lights flickering in the building opposite.Han Feng hugged Xiao Lin in time and saw that Xiao Lin was safe. Qi Sizhe went to the building opposite and saw someone.That person was quickly caught by Zhu Qingyue, it was Liu Qing.

Xiao Lin insisted that Liu Qing really cared about them and wanted to find a way out of despair for them.Liu Qing also told the police that Zhai Xixi and Xiao Lin paid because they loved their families and loved them enough to sacrifice themselves and use their own lives to relieve their family's pain, so she cooperated with Wang Chen.

The medicine bottle at Xiao Lin's house also had an imprint, just like the one at Li Shuting's house. Xiao Lin said that Wang Chen gave it to her, and that everyone in their group had such medicine, and she had taken it before jumping off the building.When Zhu Qingyue was visiting Xiaoshan in the hospital, he accidentally discovered the man who injected drugs and tattoos into Li Yiqi, so he quickly chased him out.

Episode 14

Based on the fact that the taxi's gear lever was not in the gear position and the tire marks at the scene, Han Feng speculated that the murderer pushed the car into the lake after killing the people.Zhu Qingyue said that she saw the suspect in Li Yiqi's case, so she insisted on returning to the station despite her injured hand. Fortunately, she avoided the other party's car in time, otherwise the consequences would be disastrous.According to Zhu Qingyue's description, the suspect's portrait came out, but the suspect was wearing a mask.

Sanitation workers found a body in the trash can. There were no cameras near the scene. The deceased was a young woman. In addition to her face being destroyed, all the fingerprints on her hands were also destroyed.Qi Sizhe conducted an autopsy and found that the cause of death was massive hemorrhage from the right carotid artery. The wound was very special. There are currently no missing persons that fit the criteria.Zhu Qingyue remembered an unsolved case fourteen years ago. The wounds in the two cases were very similar.Qi Sizhe needed more information to determine whether the murderers' methods in the two cases were consistent, so Han Feng took Qi Sizhe to visit the police who handled the case.

The deceased in the unsolved case is named Fan Jiangxue. He likes painting and often goes to the back mountain to sketch.Because a murder of such a heinous nature had never occurred in the small town, and the investigation conditions were limited more than ten years ago, the case remained unsolved.Fan Jiangxue's good friend Hu Jie often went to the back mountain with Fan Jiangxue to sketch, but on the day of the accident, Hu Jie did not go. After the accident, Hu Jie was arranged by her family to study abroad.

Su Huaining found a girl on the Internet who had the same tattoos as the victim. This girl had been studying abroad and had just returned to China recently. After sending the photo to Han Feng, Qi Sizhe recognized it as Hu Jie at a glance.There is an abandoned hut in the back mountain with overgrown trees and weeds. This is the scene of the first unsolved case. At that time, the forensic doctor determined that the cause of Fan Xiangxue's death was that he died of excessive bleeding due to a stabbing of the carotid artery. The murder weapon was a pen, but it was not found at the scene. The reason why it was determined that the murder weapon was a pen was because the wounds matched each other and pen water was found in the wound.There was an easel at the scene, and there was a pen beside Fan Jianxue, but she only had her fingerprints, and there was no blood on them.The scene was swept and only one hair was found.At that time, the police determined that the murderer was left-handed and his hair was broken and had no hair follicles, so it could not be used to determine his identity.There was no painting on the easel, and the paintings Fan Jiangxue had painted at that time were missing.

The police went to Hu Jie's home to collect evidence. Hu Jie returned to China a few months ago, and her parents are still abroad.Hu Jie's home is filled with paintings, all of which are signed by H, except for the one she is copying on the table.A large amount of blood was found in Hu Jie's room, and a large amount of wiped blood was also found in the bathroom. It was determined that her home was the scene of the first crime.

The unsettled case was transferred to the bureau. In addition to Fan Jiangxue and Hu Jie's fingerprints, the unsigned painting had a third person's fingerprints on it.After expert appraisal, the unsigned painting was painted by a third person besides Hu Jie and Fan Jiangxue. He should be a left-handed person. Experts pointed out that Fan Jiangxue’s painting skills are relatively immature, and Hu Jie’s painting feels like a copy of the unsigned painting.

Qi Sizhe believes that although the murder weapons are both pens, the murderers' methods are different.Han Feng judged that the murderer probably targeted the carotid artery. Fourteen years later, the murderer was even more clean and crisp when killing people.Su Huaining told Han Feng and Qi Sizhe that Fan Jiangxue's hair at the scene was inconsistent with Hu Jie's.

Zhu Qingyue went to investigate the restaurant where Hu Jie had dined before he was killed. Judging from the surveillance, Hu Jie had a big fight with the man who was dining with him.The man is Ruan Mingyu, Hu Jie's agent, who is responsible for selling paintings to Hu Jie.Ruan Mingyu said that the reason for the dispute was that Hu Jie reneged on a painting that had been negotiated for a deal. Zhu Qingyue showed him a photo of Fan Jiangxue, but Ruan Mingyu said he did not recognize it.

Han Feng found a painting that was exactly the same as the unsigned painting at Ruan Mingyu's house. The name on it was Ruan. Han Feng asked him if he had ever been to Lijia Town. Ruan Mingyu ran away after hearing this. Han Feng hurriedly chased him out.
