Su Muqing, a former daughter of a wealthy family whose family went bankrupt and became an abandoned daughter, became an embalmer in order to make a living. She was born with yin and yang eyes and can see the "dirty things" that ordinary people cannot see. During one job, she came into contact with a corpse that had died in a strange shape, and discovered that its soul was not separated from the body normally, but was twisted and torn apart by a malicious force, turning it into a "lost soul" causing trouble in the city. From then on, her life was involved in a series of bizarre supernatural events.
During the investigation, she met Lin Yuan, a programmer who ran a night market stall near the funeral home. He looks cold and dull, but he always appears at critical moments, using his mysterious hacking skills and knowledge that doesn't seem to belong to this era to help her track down clues. Su Muqing gradually discovered that her family's downfall was not an accident, but a conspiracy targeting her "soul-crossing person" bloodline. She also discovered a forgotten "space spring", a holy place for soul purification, but it was on the verge of drying up.
