MTL - Book of Technology - Chapter 321 agree

As a kind of punishment, the wings of a demon king were cut, and he eventually lost all of his power. To get back his power, he made a deal with the angel. He will go to the realm of humans to find a special girl with a special skill who is meant to be her queen. If the woman got pregnant, all of his sins would be forgiven, and he will regain all his powers. But he didn’t think that knowing her would be an adventure for him as the king of demons in the human realm.

He doesn’t want to be wanted for bounty, or be a pirate, but if there’s no other choice, he can only become a pirate…..

Let the world turn upside down!
