Mecha Zhengdao Galaxy Cavalry

Wang Zhuo, a seventeen-year-old federation boy, makes a living by scavenging on the garbage planet "Ash Star". He relies on his gifted "metal resonance" ability to dig through metal garbage dumps. He pieced together a patchwork stitched mecha "Rusty Iron", and later accidentally discovered a self-aware alien liquid metal "Source Heart" in an abandoned mine. This strange piece of metal "Source Heart" from the destroyed planet is integrated into the Rusty Iron, giving the tattered mecha a real "soul". Wang Zhuo named it "Gold", and they established a strange bond in the interstellar garbage dump. At the same time, mankind's old enemy "The Void Devourer" quietly invaded the Ash Star. When the military was defeated, Wang Zhuo was forced to fight for his life in this seemingly ridiculous assembled mecha. The story of scrap metal and miracle, boy and living mecha begins in this seemingly impossible battle to win.
