I! Ghost Missions from the Underworld Sign in the Underworld for Nine Thousand Years!

When the underworld was first opened, the realm was small and there were no ghosts in the underworld. Li Changsheng traveled through time and became the only ghost servant. After obtaining the god-level sign-in system, he began to develop obscenely. During the day, he signed in to the underworld and received rewards; at night, he arrested ghosts and maintained order in the Yin and Yang realms. In this way, with his efforts, the underworld has thirteen stations and eighteen levels of hell, and the realm has expanded infinitely. He conferred the title of Emperor Yin and appointed the Ten Palaces of Yama, and he himself grew from a small ghost servant to the supreme master of the underworld. Nine thousand years later, an old monk named Ksitigarbha led three million Buddhist soldiers to the Netherworld, proclaimed himself the leader of the Netherworld, and under the banner of vowing not to become a Buddha until hell is empty, he wanted to establish a dojo in the underworld and enjoy the merits of yin and yang reincarnation. King Ksitigarbha occupied the magpie's nest and stole the merits from Li Changsheng. Is this okay? This novel and its characters are purely fictitious.
