Shocking! I Inherited a Haunted House

A down-and-out young man runs a haunted house that nobody visits. By chance, he activates the Great Yama System, which lets him summon all the evil ghosts and asuras of the underworld to work for him. From then on, he reaches the pinnacle of life! What? The haunted house is boring, not scary enough, not thrilling enough? Li Bai laughs. Black and White Impermanence greet the guests, Ox-Head and Horse-Face work for him, and hanged ghosts, starving ghosts, and rakshasas roam the night. So tell me, is it scary? Is it thrilling?
