After Pangu created the world, it was divided into six realms: the divine realm, the fairy realm, the devil realm, the demon realm, the human realm and the void. The divine world is a place guarded by the dragon clan for generations, the fairy world has the phoenix clan, the demon world has powerful demon kings, the demon world is dominated by the Banshee Queen from generation to generation, the human world has the hereditary descendants of Pangu, and the purest place in the six realms - the void, is guarded by the fox clan. It is said that people are born in nine levels, and there is no shortage of people who cultivate immortality in the world. Some of those who cultivate immortality enter the demon world by mistake, and some ascend to become immortals. All those who cultivate immortality enter the demon world, the demon world, the fairy world, the emptiness, and the divine world based on their qualifications. The human world is the lowest level of the six realms, followed by the demon world, the demon world, the fairy world, the void, and the divine world.
