In 2242, this is a cyberpunk world where technology is highly developed and social classes are solidified to the extreme. The upper-class "cloud citizens" live in the "Sky Dome", a ring-shaped city suspended 10,000 meters above the sky, enjoying the perfect services provided by the AI "Tianshu", and their lives are almost eternal. The "earth hive residents" of the lower class live in surface cities shrouded in industrial waste gas and acid rain. They are like ants under rust and neon lights, making a living by relying on the technological garbage thrown from the "sky".
