Story
The Almighty Demon Lord, Resurrected!: The once-reigning demon lord, Lord Shitian, was betrayed by his confidantes during his critical ascension to become a demon saint. With the combined powers of the Five Benevolent Sects, the demon lord was vanquished. Just when the world thought it was rid of the demon lord, he reincarnates into the body of the disciple Mo Fan. With his body weakened and power lost, the demon lord can only wait patiently as he recuperates. This time, combining both demonic and human energy, he will rise again stronger than ever!
