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.
