Everyone’s Fleeing, but I Repair Things and Fight My Way Through the Apocalypse

Lu Qingzhou gave his life for his country. When he opens his eyes, he finds himself in a world beset by constant natural disasters and relentlessly pursued by ferocious beasts, where the military is leading the entire population in a desperate escape. Someone has even stripped off his padded coat and thrown him into the freezing wilderness, and he's about to freeze to death. Fortunately, there's always a way out. Not only does he awaken the ability to repair things, but an extraterrestrial visitor takes an interest in him as well. Even more surprisingly, every item he repairs can be upgraded! Matches become waterproof and long-burning, wheelchairs gain intelligent controls, and bolts fired from a crossbow hit with the force of a rocket launcher! Even an ordinary-looking snakeskin bag can become a storage bag with an enormous interior! As Lu Qingzhou thrives in the apocalypse with the things he's repaired, he suddenly realizes that his extraterrestrial employer, the one who found him in the snowstorm... seems to be looking at him a little strangely?
