Lu Chen, one of Earth's top survival experts after the apocalypse, is swept into another world by the bizarre rules of the "Fourth Calamity" and becomes a "carrier of civilization's spark" amid the clash of multiple civilizations. Drawing on his knowledge of Earth's civilizations and his instinct for surviving adversity, he transmigrates through seven otherworlds in succession, including a primitive magical continent, a mechanical wasteland sector, and a star domain where spirits and humans coexist. He confronts major villains such as hypocritical priests, technocratic governors, and mages who manipulate space and time. As he waits across time and space, he solves the crises threatening each world, ultimately conquering multiple worlds as the "spark of civilization" and uncovering the truth behind the cosmic civilization selection process that lies at the heart of the Fourth Calamity.
