Five hundred years ago, the Demon God appeared out of nowhere, sweeping across the Eight Wastelands and defeating every race. Unmatched in his time, he brought the six realms under the demon race's rule, subdued all living beings, and became the world's overlord.
But the Demon God was arrogant, cruel, and bent on slaughtering all life, determined to wipe out nine thousand races.
Humanity's strongest fighters entered the Secret Realm of Heaven's Gate and obtained the arts of demon refining and demon taming. Working with the strongest fighters of the other races, they attacked from within and without, and finally struck the Demon God down atop Heaven's Palm Peak.
Five hundred years later, the Demon God is reborn and returns.
