Time background: 2045, a near future where technology is advancing rapidly but social classes are solidified. Artificial intelligence is popularized and neural interface technology is mature, but the gap between rich and poor has reached a historical peak.
Geographic environment: The story mainly takes place in "New Shanghai" - a vertical smart city rebuilt on the banks of the Huangpu River. The city is divided into three layers: the cloud area (suspended buildings, where elites live), the surface area (civilian living areas), and the underground city (the forgotten bottom society). A "rift zone" is formed on the edge of the city due to spatiotemporal anomalies.
