Fu Xiaocheng's death was full of doubts. After receiving a report about Fu Xiaocheng's murder, the Provincial Public Security Department sent the criminal investigation team leader Wu Jianliang to Heyang to conduct an investigation. During the investigation, it was discovered that evil forces were behind the murder. At the same time, the Shannan Provincial Party Committee and the Provincial Commission for Discipline Inspection received a letter of report stating that Li Zhongzhang, the deputy director of the Provincial Public Security Department in charge of criminal investigation, colluded with the gang leaders Wu Guanglin and Yuan Minghai, acted as an aide, and acted as a protective umbrella for the gang. In the process of investigating and collecting evidence, Wu Jianliang also discovered clues that his former mentor Li Zhongzhang acted as a protective umbrella for the evil forces. A game of wits started between the master and the apprentice, who is the winner?
