During the war between humans and demons, Lu Yuan borrowed the power of his divine wife to seal the Demon God. However, his sect falsely accused him of colluding with the demonic path, forcing him to sacrifice his life for the righteous path. His son, Lu Chenzhou, had his cultivation crippled and endured endless contempt. Fortunately, Elder Cangwu taught him the Reverse Immortal Art. After his dragon-scale bloodline awakened, he joined forces with the healer Su Qingyin and his former sworn enemy Xuan Yeming to break through the Nether Abyss and venture into the ruins of the divine race. Ultimately, they united the various sects to slay the Demon God, clear his father's name, and become the leader of the Immortal Alliance.
