Deep Black: the Autobiography of a Public Security Bureau Chief

The work created a completely different image of the public security chief, and Yan Zhongxin faced an unprecedentedly complex situation: in broad daylight, as the public security chief, he witnessed the police being beaten by gangsters but could do nothing; the evil forces that he had been fighting for many years had grown stronger and actually came to the public security bureau to inspect his work; the murder and corpse mutilation case had obviously been solved, but the murderer was at large... When he was fighting against all this, corrupt elements colluded with the evil forces to expel him from the post of public security director.
