In the final years of the Great Xia dynasty, spiritual qi revival brings martial arts and immortal techniques into a world of warring factions and political strife. Chen Yan, a young man from the modern era, transmigrates into the body of a lowborn borderland heir, only to find his family destroyed. By chance, he acquires a Civilization Simulation System that can turn modern technology into ancient inventions. With the System, he improves pills, powers puppets, and redesigns cities, building a power base of his own while others remain trapped in traditional cultivation and political scheming. In the end, he fuses martial arts with cultivation, breaks through the barriers between them, determines the course of civilization, and saves it, or restarts its cycle.
