I'm Working as a Yin in the Human World

An ordinary high school student accidentally becomes a sinister agent, catching people, ghosts, or unknown horrors in the underworld. What is the so-called ghost? Is it a spirit body or spiritual energy? What dangers will he face and what path will he choose? Let's see how the protagonist overcomes all the difficulties. Ghosts hit the wall, yin and yang corpses, wandering souls, demons and monsters, hundreds of ghosts walking at night. This novel and its characters are purely fictitious.
