I, the Strongest Demon, Have Regained My Youth?!

Xin Sheng, the eternal demon king who ruled the world, ventures deep into the demon realm in search of the highest and strongest power. His purpose is to maintain his rule, but the quest consumes thousands of years. When he finally emerges, he has become vastly stronger and, unexpectedly, younger.

The world he left behind, however, has changed beyond recognition. Everything he once knew is different, and his former dominion is no longer the same. Now a youthful demon king with immense power, Xin Sheng must face a realm that has moved on in his absence.

As he navigates this unfamiliar era, he must find a way to assert his authority and adapt to a world that no longer operates as it did. His regained youth brings its own complications, and the challenge of ruling again proves far more complex than he ever anticipated.
