The Crimson Swordsmith

In the late autumn of 1927, Chen Yuanshan, a modern military-industry technician, transmigrates to the foot of Jinggang Mountain and finds himself in the body of an unemployed apprentice from an arms factory. Faced with the Red Army’s desperate shortage of weapons and equipment, he takes on the responsibility of building up military industry behind the lines.

Starting by repairing old rifles, he designs grenades, develops land mines, reloads bullets, and copies mortars. He uses primitive methods to smelt tungsten steel, make smokeless powder, and build water-powered machine tools. He never goes to the front, yet turns every weapon into a formidable tool on the battlefield.
