When the sun becomes a memory, the underground becomes eternity. A sudden earthquake tore apart the Primitive Mountains, and the "Light Eater" virus swept across the world. The infected person is transformed into a living corpse that retains intelligence within seventy-two hours, and civilization collapses within seventy-three hours. Three million "tinders" escaped through the fifty-ton lead door into the bottomless underground city, starting a century-long self-imprisonment. Here, construction worker Chen Jianguo used his stumps to carve the names of three million dead friends on titanium plates, only to find that even his memories were corroded by radon gas; virologist Lin Xiufen spent her whole life looking for an antidote, and finally committed suicide in the laboratory by taking poison, leaving behind the last words "We are the invaders"; their daughter Chen Meng was exiled for hiding a weed, and eventually turned into an eternal "vapor rose" in high-temperature steam, becoming a strange icon connecting two civilizations. Their descendants continue here: the youngest consul Chen Xiaoming surrendered to AI in order to preserve humanity, but carved the final command "Humanity stops evolving" on the wall; the iron-blooded general Chen Liang used a torrent of tanks to crush the tide of corpses, and finally screamed "they evolve faster than us" in the EMP explosion; and the last pure-blood baby "finally" wrote the history of civilization with his nails in an eternal cage until his nails broke, his teeth collapsed, and his blood ran out. When the underground civilization devoured itself in the chip era and ecological collapse, the "reversers" on the surface have established a new country. They blow open fifty tons of lead doors and issue an ultimatum to the underground people: "Accept evolution, or get off the planet with your humanity." This is an epitaph for a civilization that spans a hundred years.
