During the Celestial Empire, Japanese envoys bewitched the emperor and intended to release the demon Chi You, who had been sealed for a thousand years, to bring disaster to the world. The Qimen Sect was besieged to protect the seal. The wandering elder Dongguo met the gifted Liu Zimo and designed to take him as his apprentice. As the pursuit of the Japanese evildoers gradually tightened, Liu Zimo and his party resisted several times. Dongguo sacrificed himself to protect Liu Zimo's safety and entrusted him with the pupil arm that opened the seal. Liu Zimo, who was forced to shoulder the heavy burden, embarked on a journey of cultivation and fell into a sadomasochistic love. The Japanese enchantress Yuan Huizi took the opportunity to release Chi You. The sky and the earth changed color, the wind and the clouds surged, and a desperate battle was ready to go.
