A fully equipped team of survivors from a modern-day underground apocalypse ark, including engineers, agronomists, tactical commanders, and psychologists, transmigrates at the very moment the ark runs out of power. They arrive in a low-magic cultivation world where spiritual energy has only just begun to revive and civilization remains in a feudal age. What awaits them is no advanced immortal realm, but a chaotic world little better than the ruins of the apocalypse, teeming with savage demon beasts and ignorant sects. The team’s mission is to use the last remnants of their “flame of civilization” and “scientific methodology” to rebuild humanity’s glory in this new world, and uncover the ultimate secret behind the connection between the two worlds.
