Modern forensic doctor Lin Mo opened his eyes and became a death row prisoner in the Northern Song Dynasty. Based on the flaws of the wound angle and arsenic poisoning, he reversed the verdict in court, jumped from the guillotine into the autopsy room of Kaifeng Prefecture, held a bone knife, measured twine, and used anatomy to solve the strange case of Bianjing.
There was no soot in the mouth of the charred corpse, indicating that the corpse was burned after death; the rice in the stomach of the floating corpse contained a mystery, pointing to collusion between officials and businessmen; even the deceased who seemed to have committed suicide had a second strangulation mark hidden on the back of his neck. But in every case, there is a shadow - the "man in black robe" who taught the murderer to hide drugs and fake the scene.
When the bone knife cut open the twenty-seventh corpse, he finally saw clearly: this was not a simple murder, but a game using ancient laws as a chessboard and human lives as pawns. And his scalpel from modern times is not only to cut open the lies of the corpse, but also to cut through the conspiracy that travels through time and space.
