I recommend the Book of Life and Death to you. Similar to the Inferno Inheritance System, this novel also told the story of a transmigrator who took control of the Inferno after obtaining the Life and Death Book. The protagonist could even deal with the officials of the King of Hell's Mansion, such as Ox-Head and Horse-Face, Black and White Impermanence, and deal with the disputes between humans and ghosts. I hope you like this fairy's recommendation. Muah ~😗
