The Era of Iron: I Rely on Military Technology to Conquer All Things

Gu Xun, a doctor in military industry, travels through the world of spirits. Here magic is supreme, fighting spirit is supreme, strange beasts are rampant, and gods overlook all living beings. And he has no system, no plug-ins, and only a brain of earth science and technology knowledge. Use ordinary iron as bones to cast barrels and barrels; Use the crystal core as blood to drive the nuclear energy engine; With fighting spirit as the tendon and magic as the pulse, you can cultivate both magic and martial arts! Start with a flintlock gun, build tanks, build an air force, develop nuclear cannons, and build starships! Orcs? Just a mining slave. Magic? It's just unresolved energy. Gods? They are just energy creatures of higher dimensions! When the torrent of millions of steel roars into the sea of stars, and when the nuclear magnetic cannon tears apart the sky—— Gu Xun stood on the Nine Heavens and said calmly: "If God stops me, I will kill God. If the sky presses down on me, I will lift it up. Today, I use ordinary iron to forge an immortal era! "
