Twenty years into the wasteland era, top mecha engineer Lin Feng is betrayed by his closest family and comrades. His personal mecha is dismantled, its core technology stolen, and he dies amid a tide of exotic beasts. When he opens his eyes, he's reborn thirty days before the disaster! Armed with twenty years of mecha research experience and memories of surviving the apocalypse, while others scramble for instant noodles and supplies, he spends every last coin on rare metals and melts scrap into alloys. While others cling to life with melee weapons, he is already carving a path to survival in a first-generation mecha. From a first-generation mecha cobbled together from junk to an ultimate war machine fused with exotic beast cores; from a lone mecha engineer to an iron overlord commanding a hundred mechas. In this life, he wields mechas as blades and artillery as shields, tears traitors apart with his bare hands, stands firm against waves of exotic beasts, and crushes every apocalyptic faction! Anyone who bullies, betrays, or harms him will be ground to dust beneath the iron tide! But his goal is not merely to survive. With the steel body of his mecha, he will protect everyone he cares about and build a human stronghold amid the wasteland!
