As a Demon King, You Should Do Whatever You Want.

The Demon King, who has been imprisoned in the Demon Realm Tower for 100,000 years, clearly did not want to start a war, so why does he always come to be punished! Weak monsters keep dying, even if there are unlimited resurrections in the tower, it's too much! It was another boring day, and this brave man who didn't know who was the strongest brave man appeared and took out a disgusting artifact? After a burst of blinding light, I was transported to a new world. There seemed to be a superficial peace here? The sudden system locked the two of them. What's the secret to everything? The Demon King's system allows him to rule the world. If the Demon King just has this idea, then he reluctantly agrees. The brave man was forcibly bound to the god-level Saint Hunting System. Why would he do such a thing again? I just want to lie down. Is it so difficult? Although the hero was very reluctant, he was forced to embark on the road to rule the world with the Demon King.
