I Open an Underworld Office in the Human World

Yu Fan stayed in Qingshan Mental Hospital for three years. The doctor said that he had severe delusions and could always see things that ordinary people could not see. But only Yu Fan knew that those things really existed. That day, a mysterious visitor who called himself "The Night Watchman" broke the tranquility of the hospital. "Yu Fan, number 0017, the organization needs your abilities." Yu Fan looked at the black shadow eating the moonlight outside the window, pushed up his non-existent glasses, and showed his signature crazy smile: "Want me to help? Yes. But you have to pay more, and I want to be the captain." From then on, a crazy figure appeared in the shadow of the city. He is a taboo in urban legends, a nightmare in the eyes of strange creatures, and an eternal "logical genius" in the hearts of all patients. In this era where madmen are more terrifying than ghosts, Yu Fan decided to use the most outrageous method to protect this boring world.
