Lu Chen, a top survival expert in the aftermath of Earth's apocalypse, is drawn into another world by the bizarre rules of the "Fourth Calamity" and becomes a "spark carrier" caught in a clash of civilizations. Drawing on his knowledge of Earth's civilizations and his instinct for surviving adversity, he transmigrates through seven different worlds, including a primordial magical continent, a mechanical wasteland star region, and a star-spirit symbiotic domain. He faces major villains such as hypocritical priests, technocratic governors, and space-time mages. While waiting across time and space, he unravels the crises threatening these worlds, ultimately conquering multiple worlds as the "spark of civilization" and uncovering the truth behind the Fourth Calamity: a test to select civilizations across the universe.
