Chaos and order, love, hate, gods and demons - in the time of chaos, the Lord of the World, Emperor Apocalypse, sealed his two souls of gods and demons in the World Spirit Stone. This World Spirit Stone attracted the chords of dark spiritual matter and light spirit of chaos every day, shrinking thousands of years. Finally, after tens of millions of years, the divine soul and the devil soul collided and exploded. The World Spirit Stone was divided into two, and the two realms of gods and demons were born. Gods are born from divine souls and earth spirit stones coupled with the Apocalypse Spiritual Contract, and demons are born from demon souls and flame spirit stones coupled with the Apocalypse Spiritual Contract. For thousands of years, the two realms of gods and demons have been living in peace and harmony, and each realm has flourished and thrived. However, Yuanshi Tianzun, the leader of the generals of the God Clan, refused to accept the emperor's rule.

The human race also gained the power to open up wasteland and fight with the demon race against the gods... After the Ragnarok War, each group established a spiritual contract, and the three realms returned to peace and unity. However, one hundred thousand years later...
