In the Wasteland Era, the last starship crashed, and humanity became prey. Cheng Tingyun’s enemies broke all four of his limbs and threw him into a junkyard. Just as mechanical vultures were about to devour his brain, he grinned and flicked out a nano-welding torch. He was the wanted “Forbidden Mechanic,” capable of turning discarded prosthetics into S-rank gear with his bare hands. Three days later, when his enemies arrived with a mechanical army to raze the junkyard, Cheng Tingyun had already repaired the entire crashed starship into a mobile fortress. The cockpit was piled high with enemy captains’ heads. “You scrap my parts, I scrap your base.”
