Shen Yan never follows the rules when arresting people, but his crime detection rate is the highest in the city. Cheng Zhen stopped her in court: "Illegal evidence collection will make innocent people wronged." They had been tit-for-tat for many years until a series of medical malpractice cases broke out. Shen Yan's mother died on the operating table, and Cheng Zhen's father was shot for this. When jointly investigating the case, Cheng Zhen discovered that Shen Yan always avoided the topic of his father.

Cheng Zhen spent the night at Shen Yan's house and saw her mother's medical records - the death date was three full days later than the official record.
