Wasteland Synthesizer

After the end of the "Second Age", the earth became the largest technological cemetery in the galaxy. Scavenger Cheng Qi awakened a unique "synthesis" system in the garbage mountain, which can turn scrap copper and iron into life-saving artifacts. At the beginning, he had just synthesized a bunch of nanny robot remains into a loyal assistant when a mysterious voice sounded in his mind - it was an AI that called itself "Zero". It had no entity, but claimed to be the real source and manager of Cheng Qi's "synthetic" ability.
