In the modern city around 2025, there is a hidden wealthy class: these families control 70% of the world's hidden economic lifelines (such as energy, rare minerals, cutting-edge technology patents), and maintain balance with each other through marriages and interest chains. Ordinary people know nothing about them. The social structure is a "double pyramid": on the bright side, it is the workplace, housing prices, and 996 pressures of ordinary people; on the dark side, it is the competition for resources and inheritance rights among wealthy families. The power system does not involve the supernatural, and the core is the "game between capital and connections" - each wealthy family has its own "dark resource network" (such as black card authority, industry monopoly data, political and business protection umbrellas), and Lin Wanqiu's family happens to be one of the top five families.
