It's 2XXX year now, after World War III, there are no more countries on EarthThis concept has disappeared, and human scientific and technological civilization has gradually returned to the level of the early 21st century before the war. The world has formed metropolitan circles. These metropolitan circles are ruled by large chambers of chaebol groups, forming a system with the interests of the big bourgeoisie as the core. Due to the loss of necessary intervention by the national government, the power of the chaebol groups is extremely arrogant and monopolized the lifeline of the global economy and most of the resources. It also has its own private armed forces. Most citizens of various metropolitan areas are the lower-level working class, working for chaebols with low remuneration, enduring the deep exploitation of trade unions and other organizations that safeguard workers' rights and interests were banned, and strikes and other activities were suppressed by private armed forces of chaebols. As for Shanghai, this city was a world-famous international metropolis before World War III, and was not seriously damaged in the war. After the war, it became the economic and trade center favored by global chaebols and was renamed New Shanghai Beach.
