Once the ruler of demons, Lord Shitian, was betrayed by his closest allies while attempting to ascend to demon sainthood. Joined together, the powers of the Five Benevolent Sects defeated the demon lord. However, Lord Shitian reincarnated into the body of Mo Fan, his disciple. Without much strength or power, the demon lord must wait to recover. This time, he will combine both human and demonic energy to become stronger than before. Under the watchful eyes of the Five Benevolent Sects, Lord Shitian seeks revenge, bloody retribution, and the elimination of all evil, ultimately regaining his rightful place as the dominant demon lord.
Through an official translation, it is revealed that the demon lord was killed and later reincarnated as Mo Fan, a failing Taoist cultivator. While human and demon relations have humbled demonkind in the present, "Mo Fan" discovers a mysterious connection between demonic cultivation and Taoist cultivation.
