Lu Mingxuan, an emergency doctor, was transformed into a small prison doctor of the Ministry of Punishment of the Qing Dynasty. His first case was his own "murder". With the incomplete modern medical system in hand, he was forced to use a scalpel and scientific thinking to cut through the layers of pretense in an era of rampant superstition. From the ghosts in prison to the corpses in the canal, from the plague in Jinmen to the snow traces outside the pass, every corpse tells the story of a conspiracy covered up by "ghosts and gods". When the shadow of the "Xuanming Sect" shrouded the government and the public, he stood on the Golden Palace and used an unprecedented autopsy experiment to declare to the entire era: the biggest "ghost" in the world is the human heart.
