Modern industrial designer Lin Yuan transmigrates into the body of Lin Yuan, a down-and-out scholar from a humble family in a border town. With nothing but the clothes on his back, he sets out to master the art of engineering. Starting by organizing the villagers to defend themselves, he uses modern knowledge to transform agriculture, build waterworks, revolutionize weaponry, and train a powerful army. Amid the chaos of the Five Dynasties, he carves out a path to revival through science and technology, ultimately ending a century of warfare and restoring the backbone of Han civilization.
