From Brave Man to Devil King

Mu Xiao, who came to this world with the Brave System and the Demon King System, always told himself that maybe this world was not as bad as he imagined. He traveled through this magical world as if he had just woken up from a dream. He thought he could accomplish a lot, but unexpectedly the reality was still so cruel. To become a brave man in an era when there was no need for brave men, what he had to face was not the world-destroying demon king, but the sarcastic adventurers. The devil and the hero, when the two are combined into one, is he a devil who does the things of a hero, or a hero who does the things of a devil.
