In the modern city where supernatural beings have revived, Lu Chen is a cleaner responsible for cleaning up crematoriums and haunted houses. He is regarded as a "waste" because of his frail constitution. While cleaning out an S-class forbidden haunted house, he accidentally awakened Gold Finger. All supernatural attacks and life-threatening curses directed at him will be 100% rebounded and doubled on the ghost. From then on, when other exorcists were still struggling to support themselves, Lu Chen walked into the ghost domain with a mop. Amid the desperate screams of the evil spirits, he forcibly cleaned the scary restricted area into a five-star model house, becoming the strongest legend in the city.
