At the beginning of all things, Pangu created the world and gave birth to the world of gods, humans, demons, devils, ghosts and immortals, which are called the six realms. The five races include gods, demons, ghosts, monsters and humans. Among them, Gongsun Xuan, the Emperor of the God Realm, unified all realms and became the Lord of Heaven and Earth. The human race Fuxi and Nuwa created human beings, and the human world began to flourish. The White Emperor Jiang Hao was unwilling to be controlled by others and united with the demon world. Everyone in the demon world tried to overthrow the divine world. He was finally defeated by the Emperor Gongsun Xuan and was imprisoned in purgatory forever. After that, Gongsun Xuan needed experience, so he descended to the human world and incarnated as King Mu of Zhou. After experiencing the pain of love with the Queen Mother of the West, he had an epiphany, a golden light flashed, returned to the fairy world, and became the master of the fairy world. He transformed from a mortal to a heavenly emperor. After thousands of years of suffering and dozens of reincarnations, he became the master of the fairy world, the demon world and the human world, maintaining peace and stability in the human world and all walks of life.
