When Shen Yan, a modern forensic doctor, was dissecting an ancient corpse, he discovered a poor man who was possessed by a bronze dagger and was poisoned and killed after traveling to the Southern Chu of the Five Dynasties and Ten Kingdoms. A series of corpse dumping cases by the "Guide to Hell" suddenly appeared in Hengzhou City. The corpses of seven women were arranged in strange ghost marriage poses. On the surface, it was caused by witchcraft, but he smelled the conspiracy of the powerful from the residue of datura venom and Persian saffron dye. They form an alliance with the mute apprentice A Zhu through the "language of corpses", and then join forces with the cold-faced female head catcher Xiao Yanchu from suspicion to alliance. In the troubled times where witchcraft is rampant and the feudal kings are divided, the three of them use "modern forensic techniques" such as vinegar and charcoal to test for occult blood and gray honey for fingerprints to solve the mysteries of living poisons and human figurines.
However, every time the bronze dagger is used, his modern memory will be extracted. A Zhu's golden pupils hide the bloodline of the previous imperial physician, and Xiao Yanchu's Broken Rainbow Sword is actually related to the treasure map of the previous dynasty. When the thousand-year-old conspiracy of the Corpse Analysis Pavilion surfaced, Shen Yan had to choose between "using modern knowledge to subvert the troubled times" or "being swallowed by ancient memories" - what he left behind was not only the autopsy grid and the Penicillium antidote, but also the truth written scientifically on each corpse.
