Civilization Exchange

About 3,000 years ago, the "Siyuan Plague" broke out: the "nihilism" theory proposed by a philosopher could physically infect the brain through language transmission, causing large-scale mental collapse and death. Civilization Fault: All philosophy, art, and purely theoretical research are urgently suspended. About 2,800 years ago, the "Civilization Covenant" was signed, the Knowledge Censorship Agency was established, and the ideological control system that continues to this day was formed. Three thousand years later, technology continued to develop, but culture stagnated. Architecture is functional (no decoration), language is instrumental (no poetry), interpersonal relationships are utilitarian (no abstract emotional expression), a civilization that "has the ability to navigate the stars but cannot write a decent lyric." About 50 years ago, a small number of "thought smugglers" were operating underground, but censorship technology has been upgraded and the survival rate is extremely low. On the black market, a collection of poems can be exchanged for a city.
