Demons Run Amok: I Returned Invincible

Eighteen hundred years ago, after pacifying the realm, he refused a noble title and retreated to the mountains.

Eighteen hundred years later, demons roam everywhere and strange beings run rampant. The imperial court establishes the Demon-Slaying Bureau.

Ten years after the bureau's founding, he returns from the mountains, determined to restore peace to the realm.

Demon King: "I tried to reason with you. Why did you have to start hitting me? Forget it, I surrender!"

Lord of the Strange: "I already agreed to stop my underlings from harassing the Central Plains. Why are you still picking on me?"

The male lead spreads his hands. "I just want a peaceful, prosperous age, so I can retreat to the mountains without a worry. Is that really too much to ask?"

The powerful figures from every faction before him tremble in fear.
