Thousands of years ago, heaven and the devil fought a fierce battle that lasted forever. It is said that the war lasted for seven days and seven nights, with mourning everywhere in heaven and countless casualties, just like purgatory on earth. Originally, the victory ticket of the Demon Realm was in hand, but for some unknown reason, the Lord of the Demon Realm, the Black Devil, was willing to surrender, and his whereabouts are still unknown. Thousands of years later, an immortal predicted: "The disaster is coming, and the goddess will come to the world. If you get the goddess, you will rule the three realms." As soon as this statement came out, a group of demons immediately came out.
