Counterattack: I Engage in Industry in the Magical World

This is a world where magic reigns supreme. Those with magic power are at the top, while those without magic power are reduced to livestock. Linn came from time to time, happened to have no magic power at all, and was waiting to die on death row at the beginning. But in despair, he met the equally desperate Ella - the daughter of the Blackstone Lord, a magic genius but suffering from a terminal illness. The two make a deal: she gets him out, and he gives her power. From then on, in the abandoned tunnels of the Blackstone Mine, the fire of the steel-making furnace illuminated the darkness. Lin En used his knowledge of materials from his previous life to ignite the industrial revolution step by step, starting with steelmaking. Gunpowder, muskets, cement, telegraph... Technologies that have never been seen in the magical world are born. For the first time, the coolies had the power to fight against the magicians, and the farmers saw the hope of changing their destiny for the first time. When the army of magicians presses forward, what awaits them is volleys of musketry, coverage with rocket launchers, and penetration by magic-breaking bullets.
