I Have Ruled the Continent Since the Demon King

As the king of the demons, Louis successfully defeated the brave coalition forces of the four countries in the final battle. I originally thought that if all the brave men turned into ashes, I could unify the continent. As a result, Louis found that he was obviously overthinking. "Please stop the Holy Sword from choosing a new hero." "Please investigate the relationship between the four kingdoms" "Please ask the devil to unify the continent as soon as possible" In desperation, Demon King Louis had to set off to other racial societies besides the demons to look for clues. The mixed conflicts of races, the mysterious lost race, the mysterious holy sword, and the relationship between demons and humans. Could it be that the war that lasted for thousands of years was just a hoax? This is a story about a demon king searching for the historical truth and gradually unifying the continent.
