Among the beings of the Three Realms, anyone who possesses divine power can cultivate. Divine power comes in many varieties, each with its own level of strength. The most common is the divine power of the Demon Soul Realm. The strongest kinds are the divine powers of the Chaos Realm, the God-Eater Realm, the Spacetime Realm, the Six Paths of Reincarnation Realm, the Vajra Realm, and the Qi Refining Realm. There are also many rare varieties, such as ghost-witch arts, psychic powers, and nature-based powers.
A destitute prince of a fallen kingdom, with all his meridians damaged, was tricked by a villain and castrated. By chance, he encountered the remnant soul of the ancient immortal god, the God-Eater Emperor. The two merged, and he embarked on a quest to restore his manhood, kill his enemies, and reclaim his kingdom. Leading billions of mortals, he resisted the invasion of the Heavenly and Earthly Realms, fighting from the mortal world to the Netherworld and then on to the Heavenly Realm. In the great war of the Three Realms, across this boundless land, I alone shall reign supreme.
