The acid rain in Folding City couldn't wash away the smell of engine oil in the lower city. Lu Chen, wearing faded yellow and blue takeout clothes, stopped his motorcycle in a dark alley where the neon lights couldn't shine. Others relied on mechanical prosthetic eyes to scan for scraps, but the residual jade at his collarbone oozed warmth, and a green light lit up under his retina, illuminating the old dream of cultivation buried by cybertechnology. A silver needle snatched a dying life from the hands of the plutocrats; a piece of waste stone cut out the remaining monument that suppressed the fate of the old empire. When genetic modifiers and mechanical poisoners tried to monopolize the relics of the old era, this low-level deliveryman who would nod his thanks when receiving tips and eat cold box lunches on the street corner all year round stepped on the remains of mechas on the ground and rekindled the incense of cultivation civilization in the steel jungle.
