The entire universe is divided into inner and outer universes. The two universes are enemies of each other. The outer space is ruled by demons, and the inner space is divided into the divine realm, the eternal realm, and the human realm. There are countless mortal worlds like Heavenly Continent in the universe, collectively called the Nine Heavens New Regions. In the Field of Nine Heavensin, nine immortal emperors commanded all nine layers of starfields. Above the Nine Heavens is the Purification Realm of the Immortal Gods.
