I'm the Boss of the Underworld: From the Start, I Led Ghost Soldiers into the Human World

[Ghost Taming + System + Sign-In + Female Lead (or Multiple Female Leads)] After transmigrating, Li Zhi becomes the priest of a temple and immediately clashes with the monks halfway up the mountain! What? Sign-in rewards include a ghost compendium and a ghost-suppressing hammer? And there's a beginner's gift pack too? Wait... what did you say? I'm actually the Son of Heaven of the Underworld after transmigrating? I'm the one in charge down there?
