The red mist descends, the world becomes distorted, mutated monsters run rampant, and human civilization falls into ruins. Gu Chen, a precision instrument engineer, was trapped in a hardware warehouse and awakened the evolutionary power of all things in the thin line between life and death - any item can be upgraded and strengthened, and evolution points can be obtained by killing mutant creatures and superpowers, unlocking a new evolutionary path.
From a low-quality wrench to a sharp warhammer, to a rusty iron door upgraded to an automatic defense gate, Gu Chen used the meticulous thinking of an engineer to transform scraps into a doomsday fortress, using extreme rationality to lay out the defense line for survival. He rescued medical student Su Wanqing, and the two divided their labors and cooperated. While hunting monsters to accumulate evolutionary points, they also built greenhouses, water purification devices, and hot forging furnaces to build a complete survival system.
With his special powers, Gu Chen crushed greedy thugs, cracked deadly traps, and built the scrap station into an impregnable safe base. But the crisis has not stopped. Mysterious high-altitude behemoths are attacking, unknown energy sources are approaching, and the truth behind the military refuge lurks murderous intent... Faced with increasingly terrifying mutated behemoths, sinister human nature, and unknown threats, Gu Chen continues to evolve weapons, upgrade defenses, and unlock stronger abilities. Using all things as soldiers, he uses evolution to break the situation. He protects his companions in the apocalyptic wasteland, explores the truth about the red mist, and embarks on an ultimate survival path unique to engineers.
