Three hundred years after the Collapse Night, Earth has been reduced to a wasteland of garbage. Ning Zhuo, a boy from the Gray Port, possesses hands that can see through machinery and can predict every part malfunction. Relying on extraordinary precision, he creates miracles time and again, yet he believes that "precision can replace trust," and is isolated by the whole city for being too outstanding. When he builds a machine that requires multi-person coordination to start, he suddenly realizes that no matter how perfect the parts are, they cannot mesh and operate alone. He lets go of his pride, shares his technology with everyone, casts the magnificence of civilization with the fineness of microdust, and knocks open the path to the starry sea for surviving humanity under the siege crisis of the Constant Steel Society.
