Episode 2

Before Guan Hongyu was about to meet with forensic doctor Gao Junran, Zhou Xun repeatedly reminded him to be careful in his words and deeds and not to analyze the case without authorization, so as not to be spotted by a highly intelligent person like Gao Junran.However, Guan Hongyu didn't take it to heart. He used the simplest logic to speculate on the facts of the case. He even called the deceased a victim without authorization before the case was concluded.

Zhou Xun was with him the whole time, feeling uneasy and interrupting Guan Hongyu's speech from time to time, or adding details to his reasoning, trying to guide him back on track.Zhou Shutong was simple-minded and did not notice anything strange, but Gao Junran had doubts about the “Guan Hongfeng” in front of him, feeling that he was not as sharp as the rumors.Guan Hongyu's sophistry made Gao Junran waver in his judgment, and mistakenly thought that he deliberately called the deceased a victim as a test for him.

At the same time, the Yinsu Bar welcomed a mysterious man, and Liu Yin keenly noticed the blood stains on his hands and threatening words.When Liu Yin turned around, the man took out the steel string from his sleeve and tried to commit murder. Fortunately, Han Bin appeared in time to resolve the crisis and confronted the man head-on, so that he did not dare to act rashly.

The police have made no progress in investigating the tunnel. No case has been reported so far, and the identity of the deceased remains a mystery.The emergence of a subway ticket with the deceased's fingerprints brought a turning point to the case, and the search scope was locked around Fangqiao Station.Zhou Xun took the initiative to ask Ying to be responsible for the vehicle inspection work, while Guan Hongyu was responsible for the difficult task of monitoring and investigating.

Everyone worked separately and worked all night but achieved nothing.Zhou Xun knew that Guan Hongfeng was the key to solving the case, so he persuaded Guan Hongyu to contact Guan Hongfeng for help.Guan Hongyu accidentally discovered the pattern of traffic police tow trucks while buying breakfast, and thought that the deceased might have left clues due to illegal parking.Zhou Xun was overjoyed after hearing this and praised Guan Hongyu for being like an elder brother.

Following this clue, the police confirmed the identity of the deceased and learned about his family and work background.At the case analysis meeting, Guan Hongyu was in a state of confusion due to staying up late and was still in a state of confusion when he was called by the police for questioning. Fortunately, Zhou Xun rescued him.

Subsequently, the Municipal Bureau officially appointed Zhou Xun as the deputy captain of the detachment, and decided that Shi Bureau would continue to serve until the captain was appointed.Zhou Xun was grateful for Shi Ju and promised to solve the case as soon as possible.

Han Bin made an appointment with Guan Hongfeng and told him that someone had attacked him. The Liu Yin incident was just the tip of the iceberg, and the real threat was yet to come.Han Bin provided the portrait and characteristics of the Steel String Man and suggested temporarily closing the Phoneme Bar to avoid the limelight.Guan Hongfeng became extremely anxious after hearing this. He called Zhou Xun and asked him to return to the detachment, and asked him to persuade Guan Hongyu to give up.

Guan Hongyu stayed in the control room for several days, exhausted, and decided to let Guan Hongfeng come back to replace him.On the other side, Zhou Shutong and others visited and investigated the deceased's family and colleagues, and found a series of suspicious clues related to the deceased.Based on these clues, Guan Hongyu speculated that the deceased might have an interest dispute with someone, which led to two deaths.Although Zhou Xun was worried that Guan Hongyu's reckless behavior would cause trouble, he secretly cooperated with him to cover up his fingerprints.
