Iron Blood Journey 1937

War flames blaze across the land, the nation shattered. An ordinary computer science graduate student unexpectedly obtains a mysterious military-industrial support system. Starting from reverse-engineering the first heavy machine gun, to building heavy artillery, armored fighting vehicles, and fighter squadrons—he uses steel and gunpowder to carve out a path to survival beneath the enemy's iron heel. Others fight wars by throwing lives away; he fights wars by crushing with equipment. Enemies think they face only a ragtag force, unaware that behind every battle stands an endless supply system. From a single automatic rifle to an iron torrent that strikes terror into the enemy. In this life, not an inch of land yielded, not a single step retreated. — Description from novelcodex.orgFull novel: Iron Blood Journey 1937 — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
