Paradox War Criminal? Chosen of Tzeentch!

You successfully transmigrate to another world with a distinctly anime aesthetic, where you become a dominant force in a country with a massive cultural export industry. You have thousands of black guys working your fields. You also have a System. She says she can summon historical figures from your past life, but... Zhang Xianzhong... Li Chengliang... Those names mean nothing to you?

In the first month, you're staring at the military budget with a worried frown when Old Li walks into your tent. He suggests borrowing a few heads from the locals and trading them to the royal family for some funding. You agree, since you can't risk a mutiny.

In the third month, insect plagues and famine strike, and you're at your wit's end. The people in the city are starving when Old Zhang pushes into your tent. "Chief, do you think goblin meat is edible?"

In the third year, while you're reading a book about social relations of production, Old Zhang happens to see it and asks you to explain it.

In the eighth year, you hold the emperor hostage to control the nobles, earning yourself the nickname Little Cao Mengde. You call a deer a horse, wreak havoc in the imperial harem, and humiliate the emperor. Everyone wants you dead.

In the tenth year, you discover that Old Zhang has suddenly led his army off to slaughter the emperor's entire family.

In the twentieth year, you strike east against the elves, campaign north against the orcs, and march west beyond the Heavenly Pass to subjugate the dwarves and the human kingdoms. The continent calls you the Demon King and brands you a war criminal. You reply: "Only the losers who get caught are war criminals."
