Xuan Qing, a nineteen-year-old Taoist junior sister, was ordered by her master to go down the mountain to practice, but was involved in the "Hundred Ghosts Night Walk" murder case eighteen years ago. The paper door god is resurrected, the faceless Nuo seizes the face, the river lantern flows against the current, the ghost sedan welcomes the bride, the mother soul sings on the bone stage... Every time a case is solved, the cinnabar of the "reverse birth formation" on her arm increases by an inch, but the memory disappears. The truth is revealed: he is actually the "eye of the formation" that the head of the family uses to exchange for his daughter's immortality. With only one year left to live, she used her remaining soul to save hundreds of ghosts, causing her enemies to fall to the bottom of the river forever, and the world could no longer remember who "Azhi" was.
