In the Wasteland Era, the last starship crashed and the human race became a hunting ground. Cheng Tingyun had his limbs broken off by his enemies and was thrown into the garbage dump, just as a mechanical vulture was about to eat his brain. But he grinned and popped out a nano-welding gun from his fingertips - it turned out that he was a wanted "forbidden repairman" who could transform scrapped prosthetics into S-class divine armor with his bare hands. Three days later, when the enemy led the mechanical army to destroy the garbage dump, Cheng Tingyun had repaired the entire crashed starship into a mobile fortress, and the cockpit was filled with the heads of the enemy captains: "You dismantle my parts, and I will dismantle your base."
