I, the Demoted Prince, Became the Supreme Emperor.

Thousands of years ago, a generation of demon lord led the demon clan to stir up trouble in the three realms. The human race and the demon race colluded with each other and used their conspiracy to chop off my head and tear my body apart. Fortunately, Heaven has not deceived me and allowed me to step into reincarnation... The ways of heaven are impermanent, but the ways of devils are eternal. We, the devils, should not be afraid of a battle!
