In the last years of the Qian Dynasty, monsters were rampant, and the court was full of evil spirits dressed in human skin. Tantai Jing, who was originally an unknown copyist in Dali Temple, accidentally obtained a "Book of Judgment of Sins on the Underworld" that can see through other people's "karma" and "death disaster" while sorting out the abandoned files of the previous dynasty. Just by turning the pages of the book, he could see the innocent souls behind corrupt officials and the lurking shadow of demons. In this troubled world where human life is at stake, Tantai Jing relies on poor information to wander between the powerful and the evil. He is not trying to save the world, he just wants to seek real justice for himself and those who have no way out in this world of cannibalism.
