The Hidden Dragon of Great Qin

I transmigrate into the body of a disgraced prince sent into exile, and from the start, my entire village consists of nothing but the old, the weak, the sick, and the disabled. I bind myself to the National Destiny System and turn wasteland into farmland, growing sweet potatoes that yield three thousand jin per mu. Bandits show up? I dig a pit and bury them! The prefect makes trouble for me? I blast his place flat with gunpowder! Assassins from the Web? Perfect, I need someone to guard the door. When Zhao Gao’s army of a hundred thousand comes to lay siege to my city, I already have three thousand peasant soldiers behind me, trained and arrayed in battle formation. It’s time for the world to be ruled by someone surnamed Ying.
