The ancestral founder of the Gu family, who has been sleeping for more than nine hundred years, is dug awake by a rebellious descendant with a hoe, and gets dragged into infinite horror instances. While others struggle to survive, she seeks death; with anomalies running rampant, she self-proclaims as the principal and changes the rules. Supernatural entities back down and bosses admit defeat—until she discovers that the ultimate boss looks exactly like that charlatan professor. And this professor, who knows everything about her reincarnation secrets, is precisely the master she apprenticed under in her past life. For what reason is the person who personally taught her nine hundred years ago waiting for her at the end of the instances?
