A global nuclear explosion turns humans into wild dogs in the wasteland. Ye Wan was kicked out of the survivor team because of his weakness and was thrown into the radiation dead city to fend for himself. He looked down at his useless hands that could only twist screws and smiled. Three days later, when the sixth-level mechanical beasts that killed through the North District leveled the camp and everyone fled, an abandoned and broken mecha suddenly stood up - the hatch was opened, Ye Xuan was holding a cigarette in his mouth, and a mechanical heart was beating hotly in the palm of his hand. Waste? I am the last mechanic on earth. Everything is a mecha and can be disassembled and reassembled! From today on, I will rewrite the rules of this wasteland. What's cool: rub the light speed engine with your hands, challenge a natural disaster-level mechanical beast, and make the old tyrant kneel down and call him daddy.
