In 2500 AD, civilized archaeologist Lin Fan discovered a breathtaking truth: human technology and intelligence are irreversibly declining following certain cosmic rules. The glorious "technological explosion" of the past is like the afterglow of dusk, replaced by global cognitive degradation and the exhaustion of creativity. Faced with this quietly coming death sentence for civilization, mankind was forced to enact the "Survival Act" in an attempt to preserve the last fire in the long night. Lin Fan became an observer of the "Lighthouse of Civilization", spanning tens of thousands of years with the iterative method of consciousness, witnessing with his own eyes the steel jungle fading into farming fields, and the hymns of rationality finally turning into myths of ignorance... Until humans returned to apes, and the last vestiges of civilization were forgotten under the soil of the rainforest. This is a grand epic about the shackles of wisdom, the cycle of life, and how humans stick to their dignity and memory before the destined end.
