Detective

Lu Chen, the former leader of the criminal investigation team, was dismissed from his post because of the "7.19 Serial Murders" three years ago. His master committed suicide mysteriously. He has since become a private detective in the old city. While making a living by accepting difficult commissions that the police are unwilling to accept, he secretly investigates the truth of the year. He was born with senses far beyond those of ordinary people and could detect even the smallest traces, but he also suffered from sensory overload. Genius forensic doctor Su Xiaotang, the master's daughter, firmly believes in the innocence of her father and Lu Chen, and becomes his most solid partner, using official resources to help him break the situation; his former apprentice Zhao Lei, struggling between the system and friendship, secretly provides convenience. A series of unit cases that are closely related to social hot topics, from disappearance cases, domestic violence killings to workplace silences, there are hidden clues behind each case, pointing to the "ghost" of the real culprit of the unjust case. The ghost is highly intelligent and anti-social, and regards Lu Chen as his only opponent. He leaves crow marks in every case to provoke him, and guides him step by step into a carefully laid out chess game. While cracking the unit case and exposing the darkness of human nature, Lu Chen gradually pieced together the full picture of the "7.19 Case" and the old grudges from more than ten years ago. A three-year showdown between good and evil began.
