Lu Chen, the top scorer in the Criminal Investigation Department of the top police academy in the parallel world, was maliciously suppressed and assigned to the "Suburban Community Police Office" at the edge of Qingzhou City because he refused to allow the second generation of top officers to use the "back door". He looks like an ordinary community police officer, but in fact he is proficient in criminal psychology, trace science, and fighting skills. During his time at the police academy, he solved 37 simulated cold cases and was known as the "Criminal Investigation Genius."
