Introduction
On a stormy night, a horrific murder occurred at a grand birthday party in a luxury hotel, and the doctor Zhou Min was killed in the bathroom. The hope of solving the case fell on the only eyewitness of the night, Chen Zihan. In the Public Security Bureau, Zihan identified the suspect on the CCTV - An Yun. At the same time, I was surprised to learn that this woman I had never met was having an affair with her boyfriend --- doctor Xu Keqin; Based on the personal relationship between the witness and the suspect, the captain Li Longbiao decided to find another clue to solve the case. Zihan was attacked, but fortunately was rescued by An Yun and picked up his life, and the relationship between An Yun and Zihan became increasingly close, which made Xu Keqin feel terrified. Xu Keqin was beaten into the cold palace by Zihan, he thought that An Yun was making a hindrance, and came to An Yun's house angrily. The next day, Xu Keqin, the chief physician of the hospital, attempted suicide by falling from a building and became a vegetative state. A suicide note was found next to the injured person, confessing to the crime of stealing narcotic drugs from the hospital and supplying them to drug production organizations because of huge gambling debts...... Li Longbiao flipped through Xu Keqin's file and resume...... He felt that Xu Keqin must still be hiding important clues, these cases seem simple, but there are many suspicions behind them! An's mother died of illness, An Yun was grief-stricken, but fortunately the dean Huang Sanquan rescued him in time. Huang Sanquan told her that Zhang Xiao was used by him to kill Zhou Min and Li Hong. And Xu Keqin was also pushed downstairs by him, because these people found evidence that he was stealing and selling medicines. Now it's Anyun's turn...... An Yun was not surprised! She said that she had already discovered Huang Sanquan's abnormality. And the people Huang Sanquan killed were all hated by himself! An Yun just borrowed Huang Sanquan's knife and killed the people he wanted to kill, including Xu Keqin and Lan Xin...... Including the sub-Han who followed at this time! And the reason for An Yun to do this is not as simple as jealousy, but a past incident and a family feud......
