In the ancient times of Honghuang, a great war broke out between witches and wizards. Gonggong, a powerful witch, battled with Donghuang Taiyi, breaking the Buzhou Mountain in the process. This caused the celestial river to flood, stars to shift positions, Honghuang to shatter, and floods to rise high enough to reach the heavens. Nüwa, the saintly mother of humanity, unwilling to see her creations suffer, smelted a thousand colorful stones to mend the sky. However, Gonggong, having been defeated and still harboring resentment, stole the colorful stones and disappeared without a trace. Gonggong hid in the Blood Sea and fell into the way of demons. In order to find a carrier in the human world that could unleash the enormous energy of the colorful stones, his demon army clashed annually with the heavenly soldiers of the Immortal Realm.
