Sign-In in the Underworld: My System Can Contain Vengeful Ghosts

The supernatural has returned, and a hundred ghosts roam the night. Taboos that lay dormant for a thousand years are beginning to awaken. Lin Ye, the night-shift attendant at a funeral home, accidentally binds himself to the All-Heavens Ghost-Subduing System during a bizarre incident involving Route 444. From then on, he sets out to subdue ghosts and grow stronger. He signs in at forbidden grounds, captures evil spirits, commands ghost domains, and trains an army of ghosts. The evil spirits everyone else avoids are his greatest weapons. As he solves one supernatural case after another, Lin Ye gradually discovers that his parents’ disappearance, the collapse of the underworld, the Netherworld Society’s schemes, and the truth behind the gods’ disappearance are all intertwined. When the taboos descend and the human world becomes a ghost domain, he has no choice but to take command of the underworld, summon every ghost, and use his mortal body to suppress the evil beings across the heavens and rebuild order in the underworld.
