The Foolish Emperor of Great Yu

I transmigrated into the Great Yu dynasty as its Crown Prince, and everyone calls me a tyrant? Fine, I’ll change. Change my foot! I’ll show you just how tyrannical I can be! The Great Yu dynasty is beset by troubles at home and abroad. What should we do when foreign enemies invade? Yu Ning has no choice but to show them what a tyrannical crown prince, and an unparalleled tyrant, really looks like! Decisive and ruthless, armed with knowledge that crushes all opposition, he becomes invincible!
