Liangjian: The Human Arsenal Factory

Materials Science and Engineering master's student Ning Haitao never expected his expertise to become a weapon of war—until he woke up in the world of Liangjian. To his trained eyes, the grassroots, gravel, and sand scattered across the revolutionary base were not mere debris, but unlit blueprints waiting to be forged. He extracts saltpeter from common vegetation, refines iron sand into deadly shrapnel, and even brings down enemy aircraft with modified kites. What the invaders dismiss as worthless scrap, he transforms into game-changing armaments. In this relentless conflict, science becomes the sharpest blade. As every inch of the land roars in resistance and the humble "millet and rifles" doctrine evolves into "all materials are weapons," the aggressors finally come to understand the true meaning of terror—when every bush and tree hides a soldier, nowhere is safe.
