The chaotic world has six realms: demons, demons, Yuanxian, Buddha, and human realms. The human realm is the weakest, the Yuan realm is hidden from the world, and the other four realms each have their own strengths. There are forty-nine great roads and three thousand six small roads. Since the ancient war, the way of heaven has been revealed and the way of heaven has been hidden. Cultivators in all realms do not hesitate to go into and out of the realm of death in pursuit of the great road, and there is not even one living person left in ten. The old monarch of the Yuan Dynasty found a great avenue called reincarnation. He sought it, but failed, and died. He left a magic weapon to the two sons. The second son inherited his father's ambition, abandoned his cultivation and followed the heaven to reincarnate in all realms in order to pursue the great road.
