From the Start, I Had a Dilapidated Prince’s Mansion, and I Built a Technological Dynasty

His soul transmigrates to the Great Wind Dynasty, where he becomes a disgraced, useless prince. From the start, he is exiled to the bitterly cold far north. The treasury is empty, and all he has is an elderly steward. Bandits lurk outside, while the county magistrate eyes him from within. The crown prince in the capital has already laid a vast trap, just waiting for him to die! Cornered, he activates the 【Empire Rising System】, which gifts him a 【Basic Chemistry Knowledge Pack】 from the start! No money? He makes soap and refined salt, stunning the Northern Wilderness and earning his first fortune! No soldiers? He smelts steel using primitive methods, then fields repeating crossbows, flintlock guns, and tiger-crouching cannons to build a modern army of iron! The nobles at court give him trouble? One enormous glass mirror is enough to leave the entire court speechless! Barbarians invade, and the border is in danger. The crown prince issues a forged imperial decree and plots rebellion? Xiao Xuan sneers. “You’re still playing at court intrigues, while my steam engine is already roaring! The day my steel tide marches south will be the day this dynasty falls and a new one rises!”
