I created my own system - Chapter 28 - : Duel to enter

A weary historian dies and finds himself in a different world awakened in a life as the notorious young Duke of a southern state. His nation is weakened, his army underfed, and his neighbors revolve around his lands menacingly. No one believes his land is going to hold out until winter.But this newfound duke is no naive simpleton his enemies recollect. He carries with him the experience of centuries of war and empire, of starting and ending monarchies. From Caesar to Napoleon, from the Mongols to world wars, he has learned from each of them—and his strategy is to make history his very own arms.He organizes his smashed levies into well-trained formations, rebuilds his castles, and turns his villages into supply centers. Where others see defeat, he senses opportunity. As he triumphs, rumors spread: of a pennant red as winter snow that shall not go to ground, of a bloody duke who writes his name in gore and flame.Is he a savior who's constructing a new empire, or a tyrant who's going to bring the world to endless war?

He learned that in this other world, there is magic and witchcraft, and depending on how you train them, you can become as strong as you want to be, so he decided to become the strongest demon king in order to recreate the story of justice and evil he once dreamed of.
