In 1938, southern Shandong fell.
Lin Yue, a former military ordnance support soldier, transmigrates behind enemy lines. From the start, he has only eleven survivors and three battered rifles, while outside waits a Japanese search squad with excellent equipment.
Fortunately, he awakens the "Battlefield Military Engineering Compendium."
Any weapon he gets his hands on can be analyzed for its structure, diagnosed for faults, and assessed for possible modifications. But the compendium doesn't give him rifles or cannons, and it certainly can't conjure bullets out of thin air.
What can he do without weapons?
Steal them from the Japanese!
Repair rifles, build mortars, capture mountain guns, seize tanks, and commandeer an armored train. Then haul the captured machine tools aboard and build a mobile arsenal behind enemy lines!
While the Japanese still think they're encircling nothing more than a guerrilla force in the mountains, the armored train Black Dragon rolls out of a tunnel, and cannon barrels rise all across the hills.
Lin Yue: "Other people rely on supplies from the rear to fight. Every gun and cannon I have was delivered by the Japanese themselves."
From eleven survivors to an army of ten thousand, from three battered rifles to a flood of steel.
Every scrap of iron on this land will eventually become a bullet fired at the invaders!
