In the cave of the apocalypse, Xiao Heng was treated as an unawakened waste and sacrificed to the mutated star beast. Monsters were surrounding him, but he stared at the S-class wreckage and murmured to himself: "This engine can still be used if it is modified." Everyone thought he was crazy - until the starship industrial machine that had been dusted for hundreds of years rekindled in his eyes. He removed parts from scrapped mechas and pieced together blueprints from ancient wreckage. While others were still jealous of an energy gun, Xiao Heng had quietly repaired an interstellar battleship. On the wasteland, he raised it casually, scrapped the mecha and knelt down to restart it. On the day when the starship reappears, all races must understand one truth: mechas are a man's romance, and he is the only genius in the universe who holds a starship maintenance qualification certificate!
