The story takes place in an imaginary ancient dynasty - the Dayin Dynasty, where humans and ghosts coexist, and imperial power and supernatural powers are intertwined. Among the people, there is a "tombkeeper" who is responsible for guarding the tombs of princes and ministers of past dynasties to prevent corpse transformation and tomb robbery. The imperial court had a Spiritual Control Department that specialized in dealing with supernatural incidents, but ordinary people kept it secret.
