Fengtian Snow Palm Blade

When military engineer Shen Yan opened his eyes, he was transformed into a refugee in Fengtian in 1908. He only had an ordnance notebook in his pocket and was bound to a system that was not invincible. It happened that Zhang Zuolin was testing the gun and the barrel exploded. The old Japanese gun injured someone. He clutched his notes and shouted "I can repair it" - he used horseshoes to make the firing pin and copper coins as gaskets, and he just changed the broken gun into a good one. From then on, he followed Zhang Zuolin, repairing guns, modifying machine tools, tinkering with gunpowder, and working undercover in Tsarist Russia's fake guns, Japanese spies, and the Ordnance Department. The snow in the Northeast is cold, but he wants the gun in his hand and the brothers in the camp to become the strong bones to protect the soil.
