I, the Demon King, Am Invincible, so I Am Reborn.

I, Barbatos, am a notorious demon king, in the eyes of the world, but the demons still respect me. Because it is too boring and there is no opponent, so I choose to be reborn in the world 1000 years later. But this is different from what I thought. The people here are actually weaker? But there is nothing that can be done, even if the devil chooses to be reborn, it cannot be reversed. At the same time, due to the rebirth of the Demon King, a group of demons that had been suppressed for a long time began to move around, preparing to occupy the empire after a thousand years. Since then, Barbatos has embarked on a thrilling fantasy story. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
