Evil spirits are based on self-cultivation, benefiting and accumulating rewards throughout their lives, but evil demons long for themselves as immortals, deliberately controlling the entire demon world, and blaming one side. Bai Tongyi led judge Lu Zhidao to overcome difficult obstacles, avoid killing long-life henchmen, and go to the demon world to regain control of the six Dao Tianshu. In the end, Lu Zhidao eliminated demons for life, defeated the forces of evil for long life, and returned peace and beauty to the demon world.
