The night in the city is cold and ruthless, like a sleepless steel maze, and the lights shine coldly on the earth. This is the city of the future, a giant city with distinct layers, where light and darkness coexist. The colorful advertising screens in the sky interweave into a bright light curtain, constantly projecting desire and vanity to the upper class people. To them, this is a wonderful and perfect city where technology brings comfort and security. But in the lowest neighborhoods, those lights seemed out of reach, like a mirage. This is the "grey area", located at the lowest level of the city. Daylight can hardly penetrate the dense layers of buildings, and only some sparse lights slightly dispel the darkness and cold. The streets in the Gray Zone are narrow, sewage flows across them, and the air is filled with the smell of dampness and decay. The residents here are called "grey people", the lowest social beings. They are responsible for maintaining the city's infrastructure but have no status. Lin Yu is a member of the gray area. He is 27 years old and has a thin build, dark complexion, and eyes that have been patiently silent for many years. Every day, he shuttles among the old equipment and decaying facilities at the bottom of the city to perform equipment maintenance. Almost no one knows his name. To the higher-ups, he is just an insignificant screw.
