This is a world where immortality is prosperous but extremely involution - the Xuanhuang Realm. The traditional world of immortality adheres to the principle of "the weak eats the strong and repays karma", and our protagonist will be bound to the "Heaven-Defying Villain System" and obtain rewards by completing villain tasks (destroying opportunities, seizing human beings, creating inner demons, etc.), And embarking on a unique "path to the ascension of villains"!
