The First Master Craftsman of the Border Army

When he opened his eyes, Xu Chong, a doctor of materials processing, traveled through time and became a blacksmith in troubled times. Xu Chong originally wanted to make a living by his craftsmanship, but he encountered an uprising and was forcibly recruited into the rebel army. The rebel army's equipment was backward and its troops were weak. They thought they would be quickly put down by the imperial court. But I never thought that Xu Chong would be drafted into the army and join the forging camp. While others were still making swords, he made hundreds of steel and made the Mo Dao that was ahead of several dynasties! While others were still using bows and arrows, charging up and firing, he had already made a crossbow and could fire several arrows in an instant! While others were still riding blindly, he had already made stirrups and assembled heavy cavalry! The leader of the Huns: "What's going on! Aren't we the nomads? Why can they free their hands and shoot with bows?" General Zhenguo: "What do you mean by millions of iron hooves, wearing armor, holding crossbows, and leveling the palace? Aren't we the regular army?!" The contemporary emperor: "Oh... Isn't this my good brother-in-law, coming to see the court again today? I will show you to your seat."
