I Just Want to Slouch Around in This Strange World

The protagonist, Zhang Sanyi, is driven down the mountain by his master to undergo trials in the mortal world. Along the way, he encounters all kinds of supernatural beings and ghosts. Subduing each one earns him a piece of an ancient immortal's remains. In the end, he collects the entire skeleton, only to discover that supernatural forces have seeped into it and turned it into a ferocious corpse. The antagonist, Xu Yinluo, plans to possess the corpse and unleash every supernatural entity, plunging the entire modern world into terror and attaining immortality through bloody means. Zhang Sanyi enters the trap of his own accord and claims the entire corpse, foiling Xu Yinluo's plan. But he loses all memory of the world, and the world forgets him in turn.
