I Rule the Underworld, Imprisoning Gods and Buddhas Across the Heavens

[No System + No Female Lead + No Cliches] I was born dead! But I was holding the Book of Life and Death! I found myself in a bizarre place: the Eighteen Levels of Hell. To stay alive, I invited an evil ghost to live inside my body. Armed with a book that gave eerie instructions, a rusty soul-catching chain, and a hell tower with eighteen levels and endless cells, I returned to the human world after vanishing for three months. Hell is empty. Evil ghosts roam the human world. I’m going ghost hunting. As I grew stronger step by step, the figures from mythology began appearing one by one. Black and White Impermanence, Ox-Head and Horse-Face, Granny Meng, Zhong Kui, the Ten Kings of Hell... I command the Eighteen Levels of Hell and imprison the ghosts, gods, immortals, and Buddhas of all the heavens!
