The Grand Ending of the Wasteland World

"Either merge with the mecha, or be assimilated by pollution." This is the iron law of the wasteland era. Contaminated food, crowded homes, and the institute's mechas are the only tools that can defeat pollution. Everyone is implanted with a growth chip when they are born. During a scavenging trip, the orphan Lin Xia accidentally awakened a rare "swallowing" biochip. It can not only repair damaged mecha parts, but also absorb the core of pollution monsters, turn its abilities to his own use, and create a unique flesh-and-blood mecha for himself. From being able to assemble simple armor at the beginning, to gradually swallowing up the corrosive force field of the "arsenic sand worm" and the energy shield of the "crystal monster", Lin Xia's mecha continued to evolve in blood and fire. When the giant pollutant "Rust Brood" approaches the last ark of mankind, Lin Xia will initiate the final fusion process and use this body of steel and flesh to carve a way out for mankind. Is she alive? I don't know, maybe. The unrecognizable old man limped into the desert.
