The Dayong Dynasty was founded thirty-seven years ago. Empress Dowager Wu lowered the curtain, her relatives controlled the affairs of the court, and the young emperor was trapped in the palace. Folk murder cases continue one after another, with puppets claiming lives, ancient jade eating people, mountain gods exchanging souls, and water ghosts sinking corpses. The piles are dressed in the clothes of ghosts and gods, and the piles point to the old witchcraft case that was burned twenty years ago.
Shen Yanci, the head of the Qing Dynasty Prosecution Department, is an anonymous orphan of an aristocratic family. He met Su Lingwei, a private widower in Yizhuang. The half piece of old jade around her neck matched the half piece of Shen's family order in his hand. The two went from being uncomfortable with each other to walking into the abyss together carrying each other's secrets.
Some people are building bones as walls underground, while others are using living people to form formations. Shen Yanci solved the mystery, and Su Lingwei listened to the dead souls from the wreckage. Along the way, he was not investigating the case alone. It was she who accompanied him through the old mountains and rivers burned by the fire, and pieced together the truth piece by piece. The answer to the mystery twenty years ago was really revealed in the last case. And when the door opened, what he saw was more than just an unjust case.
