The Seventy-Two Transformations of Earthly Fiends, each transformation granting a unique supernatural ability. A mysterious yellow book sends Li Chang'an back to the ancient world, where he gains a new ability with each demon he slays. Skin-changing ghosts, zombie kings, spider demons... countless monsters fall beneath his sword. He acquires abilities like 'Ghostly Perception', 'Swordsmanship', and 'Demon-Slaying' from the book. As he exterminates hundreds of ghosts and looks around, he realizes that all of this is just a small wave before a massive tide.
