In the year 2500, archaeologist Lin Fan uncovers a chilling truth: human technology and intelligence are irreversibly declining according to some cosmic law. The once-glorious “technological explosion” is now like the last glow of dusk, replaced by worldwide cognitive decline and withering creativity. Faced with this quiet death sentence for civilization, humanity is forced to pass the Continuity Act, hoping to preserve its last sparks through the long night. Lin Fan becomes an observer at the “Beacon of Civilization,” crossing ten thousand years through successive iterations of consciousness. He witnesses steel jungles give way to farmland, and hymns to reason turn into myths of ignorance... until humanity returns to its ape-like state and the last traces of civilization are forgotten beneath the rainforest soil. This is an epic tale of the shackles of intelligence, the cycle of life, and how humanity strives to preserve its dignity and memories in the face of an inevitable end.
