When he was eight years old, Lu Chen witnessed his father being devoured by fire and no body was found in the ruins. This became his obsession. He is obsessed with ancient books about strange things. Because of the inexplicable intimacy in the ancient books, he firmly believes that there is another hidden reason for his father's death, so he is admitted to the Xijing Police Academy. After graduation, he and his girlfriend Su Wan, a reporter, take root in Shangjiang City and become a criminal police officer.
In the first month of his rotation, he encountered a bizarre murder. The deceased had no external injuries but his face was black and blue. The smell of the scene was consistent with that of the fire scene. Subsequent murders occurred frequently, and Lu Chen was able to see the monsters in "Journey to the West" and "The Classic of Mountains and Seas", and then he realized that he had the ability to recognize monsters. The old files discovered by his girlfriend overlapped with the demon case, and the cause of his father's death gradually emerged. He has since been involved in the dispute between humans and demons, and he is the key to this dispute.
