City of Rusted Bones

Global neural depletion has made synthetic nutrients a monopoly, with real food becoming the ultimate hard currency. The upper district's tycoons build a paradise in the clouds with genetically optimized humans, while the lower district's scavengers chew despair amidst rust and oil. Chen Mo, a bottom-tier cleaner in the lower district who survives by recycling old mechanical prosthetics, has no system, no superpowers—only a rusty spring knife and a set of survival rules that exploit the system to its fullest. To find his sister who disappeared three years ago in the 'Purification Operation,' he accidentally gets entangled in a shocking conspiracy about 'real food' and 'human evolution.' Starting with three bullets at the Red Mill, he tears apart the hypocritical rules of the lower district and saves a mysterious girl treated as 'cargo.' When the upper district's elite regard the lower-class humans as 'living resources' to be bought and sold at will, and when the price of evolution is depriving countless people of their right to survive, Chen Mo decides to use his mud-stained hands to completely overturn this lofty, hypocritical order. This is a wasteland world filled with the smell of oil, rust, and the struggle of the bottom class. Here, there are no saviors, only the grit to clench one's teeth and endure in desperate situations, and the ordinary person who dares to poke a hole in the sky to protect the faint light in their heart.
