The Mystic Void Realm.
The realm was divided into the Thirteen Realms, which carried all living things. Excluding the lower three, the other nine realms bathed in the same sun, rain, and dew, enjoying the spiritual energy of the heavens and earth. Anyone with the will to cultivate could ascend step by step from being a mortal. They could enter the realms above the Nine Realms, attain a lifespan as long as the heavens and earth, witness the splendor of the Nine Realms, and ensure the endless prosperity of all life.
The lower three realms were: The Purgatory Realm, the Asuran Realm, and the Nether Realm.
The Purgatory Realm imprisoned the evil spirits of the world. In the Asuran Realm, these spirits could re-cultivate their Spirit Roots. The Nether Realm governed the reincarnation of mortals and reformed spirits throughout the middle three realms.
The middle three realms were: The Mortal Realm, the Demon Realm, and the Elven Realm.
