During the rebellion of the Yankang Kingdom, Qin Mu attracted the demon god, which set off a great storm. Later, he followed Wu Khan into the Golden Palace of Loulan and fought all the opponents in the Holy Palace alone. He returned to Yankang, assisted the national teacher in suppressing the rebellion and building the Sun-shooting Divine Cannon. Later, he inherited the legacy of the Human Emperor and became the new generation of the Human Emperor. By chance, Qin Mu learned about his life experience. With the help of Kao Yujing and others from the Taoist sect, he started a great era of reforming Taoism and magical powers.
