Episode 10

When he learned that the murderer might be an expert with knives, a figure immediately appeared in Zhou Xun's mind - Ding Chuan, the head chef of the roast duck restaurant.When Ding Chuan was serving as the sous chef, he had many conflicts with the head chef Pang Cheng over attendance issues and became dissatisfied.

Guan Hongyu, Zhou Xun and Qu Xian met at a hot pot restaurant, but Guan Hongyu's words and deeds often had flaws. Either the questions he asked were not rigorous enough, or his eating habits were inconsistent with normal.Both Zhou Xun and Qu Xian discovered Guan Hongyu's anomaly, but they did not dare to reveal it to each other, so they could only use their acting skills to cover for him.Guan Hongyu was sitting in the middle, holding back his smile and enjoying the “performance”.

After Ding Chuan was brought back to the police station, Guan Hongyu and Guan Hongfeng exchanged identities and told Guan Hongfeng interesting stories about the hot pot trip.However, Guan Hongfeng did not find it funny. He criticized Guan Hongyu for saying nonsense and reminded him that when he has time, he should reflect on how to avoid making stupid mistakes again and how to hide himself better. This is the best way to treat each other, the case and those who trust him.Their people are responsible.

After a night of interrogation and investigation, Ding Chuan's suspicion was basically eliminated.Although he had conflicts with Pang Cheng, they did not reach the point of life and death.Moreover, he only came to Tianjin Port to work at the end of the year before last. He lacked specific motives and had a big discrepancy in time.

Guan Hongyu guessed that the rigorous baby face would return to the scene, so he asked Cui Hu to monitor Xinyuan Real Estate.Soon, the baby-faced figure appeared.Guan Hongyu acted quickly, but lost track of his target halfway.At the same time, Guan Hongfeng took Zhou Shutong to re-investigate the crime scene, speculate on the incident, and notified the Xiangyang detachment to investigate the surveillance video.

At the bus stop, Guan Hongfeng received a photo of a baby face from Guan Hongyu, and happened to pass by the baby face.After he ended the call, he and Zhou Shutong analyzed the commonalities of the three victims and tried to find the connection between them and the murderer.

Baby Face realized that he might be exposed, so he secretly contacted Mr. Pei and wanted to know the other party's arrangements for him.Mr. Pei told him to keep doing things and praised him for setting his position clearly and not being self-righteous.Babyface also asked about Guan Hongyu's situation and learned that Guan Hongyu was staring at him.

Guan Hongfeng and others went to Gong Xin's unit to learn about Gong Xin's situation from Director Qian.After learning that Gong Xin came home late on the day of the incident because the unit purchased grain and oil items, they followed this clue to investigate and believed that the agricultural trade exhibition might be the key point.Especially when investigating the third victim, they became more convinced that the murderer might be a self-employed person who comes to participate in the trade fair every April.Soon, each detachment led teams to blockade the scene and investigate one by one. The scene was chaotic.

Just when Guan Hongfeng was confused about the direction of agricultural products, a call from forensic doctor Gao Junran provided him with important clues.The plant dyes collected at the time of the crime were neutral compounds, which greatly shortened the scope of the investigation.Guan Hongfeng found the dye in a warehouse and gradually solved the mystery.However, just as he was about to reveal the truth, the murderer rushed over with a machete.At the critical moment, Zhou Shutong arrived in time and subdued the murderer, and Guan Hongfeng survived.
