His Majesty the Demon King

An innocent and lively little squirrel demon has been trapped for thousands of years. Once released, I looked up to the sky with tears in my eyes. I want to become an immortal, I want to counterattack, I want revenge, and I want a beautiful husband. Nani? Is my husband the reincarnation of a bad master? Well, let's let it go first, and then we can get revenge. This is the story of a ten-thousand-year-old demon king who counterattacks and takes revenge. No matter you are a god or an immortal, you always have to pay back what you owe.
