Three hundred years ago, Xu Xing guarded the sect's holy land by cultivating gods, killed countless demon cultivators, and helped Lu Mengqin break through the Mahayana and become the Supreme. However, he himself was seriously injured and fell into silence for a hundred years. After waking up, he saw that his master was mean and his junior sister was scheming, and his younger junior brother took his place, reducing him to a wedding dress. Xu Xing tore up the oath of heaven in public and was sentenced to leave the sect, and devoted himself to pursuing immortality. Later, he aspired to become an immortal and become the supreme demon. Facing his master and junior sister who were crying for help, he only said coldly: "Your Xu Xing is dead. Good and evil cannot coexist. He will die!"
