I'm Building a Mecha in the Last Days!

After the cataclysm, "rust disease" eroded the world and all things gradually disappeared. Only mechas were the last hope of mankind. Flesh and blood are in pain, and machines are soaring! While other mecha warriors were still struggling to survive in the wasteland, resisting the invasion of mutated creatures. However, Xia Ming had already assembled a perfect mecha and started hunting everything in the world. [Sharp magnetic storm blade] + [Sturdy alloy blade] + [Armor-breaking chain blade] = [Ultimate perfect blade]! [Electromagnetic Detection Radar] + [Infrared Detection Radar] + [Ultrasonic Detection Radar] = [Full Picture Perspective Radar]! Many years later—— A certain warrior: "God of mechas, am I strong enough now?" Mecha God: "Yes, you are already the strongest mecha warrior, my child." Soldier: "What about Xia Ming?" Mecha God: "Xia Ming? It's been a long time since anyone called me that."
