Yinsi Signs in and Inherits the Position of Judge at the Beginning

The underworld collapsed, yin and yang were in chaos, and evil spirits invaded the human world. Lin Fan, an ordinary urban youth, accidentally inherited a mysterious notebook and became the last heir to the crumbling underworld order. By signing in every day, you can unlock a "ghost employee" - from a weak wandering ghost who can only explore through walls to a vicious ghost with deep obsessions. He controls all ghosts, restores order, and reestablishes reincarnation step by step in this modern city where ghosts are as dangerous as people's hearts. But why did the sign-in system select him? What secrets are hidden in the collapsed underworld? When ancient conspiracies intertwined with real-life suffering, Lin Fan discovered that he had to face not only the evil ghosts causing trouble, but also the darkness and obsession deep in the human heart. This is the story of a man growing up in despair and establishing a new order on the ruins. He uses ghosts as blades and hearts as scales to redefine what is yin and what is yang in this era where humans and ghosts are indistinguishable and good and evil are blurred.
