Story background: Cangnan City, a fictional coastal prefecture-level city in the south, governs four core areas: the old city, Binhai New Area, Xiling Mountain area, and the abandoned military industrial port. The city hides four hidden histories of the third-line construction after the founding of the People's Republic of China, the smuggling craze in the 1990s, the real estate crash in 2000, and the fraud in the new energy industry in 2025.
