The Fiercest Man of Great Liang

Lu Chen, a modern military engineering PhD, transmigrates into the most miserable ninth prince of Great Liang. His mother, a palace maid, died early. His father despises him, and the crown prince spits in his bowl. Right from the start, he is framed for treason and sent in chains to a barbaric wasteland. The escorting imperial guards discuss selling him to the barbarians—a thousand taels of silver, alive is worth more than dead. Everyone thinks this useless prince is doomed. But they don't know that inside this shell is the soul of a retired special forces soldier. He smelts steel, makes gunpowder, builds strong walls, and trains iron cavalry. In a ruined barbaric city, he creates an iron fortress that terrifies the world. The barbarians send 200,000 cavalry south? He leads 3,000 light cavalry on a thousand-mile raid, beheading 30,000 in one battle. The crown prince and six ministries want to depose him? He sneers: 'The military tallies in your hands are forged from the steel blades I made.' From a useless prince to the guardian of the nation—this world doesn't follow reason. It follows fists. Whoever has the stronger fist calls the shots. — Description from novelcodex.org
