Sand Table of Crime and Punishment

Lin Yan has an almost cursed talent: criminal profiling. He can get into the murderer's mind within a few minutes and restore the logic behind each stab. The price is a severe migraine. Thirty years ago, my parents died in an unsolved case on the edge of a cliff. The place was so clean, it looked like it had been cleaned. Twenty years later, he became an independent profiler, but found that every case he took over had hidden connections - the second generation of rich men killed their fathers, serial disappearances, and fake suicides. Each case was more sophisticated than the last one, like someone teaching a class. What's even more bizarre is that all the crime sites form a precise pentagon, with the center of the circle falling on the apartment where he lives. Some people use the entire city as a sand table, and he is the coordinates of the center of the sand table. The deeper the investigation, the colder the truth becomes. The instructor handed him a course schedule from twenty years ago, which listed "Crime Scene Cleanup" and "Counter-Interrogation Strategies"... The real funder had been watching him in the dark. In the past ten years, at least one-third of the major cases he has participated in were deliberately arranged teaching materials. Someone used real murder cases to train his profiling skills. He is that person's most proud work. He faked his death thirty years ago and planted an obsession in his mind. Thirty years later, that man will use the criminal system he established with his own hands to kill the son he raised with his own hands. On the rooftop of the abandoned factory, the middleman conveyed the last words. Lin Yan said—— I am not a student in this class, I am the one who is here to put this class on hold.
