The three realms of gods, humans and demons.
In the battle between gods and demons, the god king desperately sealed the demon king, but was seriously injured and died, and the demon king fell into reincarnation. The two worlds were left without a master and fell into a state of truce.
Unlike the parliament of the God Realm, the Demon Realm has introduced a new leader, the third master of the Demon Realm, Bi Canglan.
In addition, the second master in the demon world escaped into the human world and disappeared.
