In the Tianyuan region of this world, there are nine heavens in the sky and hells in the ten directions on the earth. Together they are nineteen heavens and earth. Those who live in the sky are called gods, those who are in the hells of the ten directions are demons, and those between heaven and earth are called the human world. Gods and demons often fight in the human world because they cannot adapt to the laws of the other world. Leading to the destruction of human beings. Gods are among humans, and demons are among animals and birds, but their essence is not human. Although gods and demons are naturally powerful, they do not have the understanding and learning ability of humans. And there is such a human boy who walked out of the human world, ascended to the ninth heaven, and integrated the hells in all directions. Since then, heaven and earth have been unified, and there has been no more war in the world.
