The world is upside down, the world is in chaos, and the three realms of humans, gods, and demons are constantly at war. After five hundred years of war, the demon realm basically rules the three realms. Those who obey survive, and only a small number of people and gods who are unwilling to obey the destiny are left to resist. Legend has it that a pure spirit will appear in five hundred years. He can become a human, a god, or a demon. He will win or lose, depending on whether he is good or evil.
