In the interstellar era, the legendary strategy master Ye Tianqi was forced to remain anonymous due to a failed mission, and ended up working as an ordinary administrator of a scrap recycling station in the "Rust Belt", a garbage planet on the border of the empire. He originally wanted to stay away from the whirlpool of power and live a pure life, but unexpectedly found that all kinds of little people on this dilapidated planet were struggling to survive. The robot repairman next door dreams of opening a cafe, the vendors in the market are oppressed by evil forces, and even the scrapped mecha AI in the recycling bin longs to be treated gently. Ye Tianqi decided not to hide anymore, and used his unparalleled strategic mind to rebuild the living order for the people here from scratch. He uses waste products as raw materials to create civilian products that are astounding across the galaxy; he uses economic games that can be called art to force monopoly groups to retreat; he even sets up a series of schemes to make the interstellar dudes who come to provoke him, especially the mama boy commander who comes from a well-born family and always asks "What does my mother say" about everything, stage a farce of "pretending to be a pig and eating a tiger" in front of the public, but is eventually crushed. When a peaceful life was ignited, and old glory intertwined with new bonds, Ye Tianqi discovered that he was no longer guarding only this piece of stardust, but also the light in the hearts of countless ordinary people.
