In 2050, a supernova explosion triggered a global Cambrian storm, freezing civilization at an extremely cold temperature of minus 100 degrees Celsius. After returning from rebirth, Zhang Yi awakened to another dimension, emptied out tens of billions of supplies from Wal-Mart, and built a steel fortress. Faced with his neighbor, White Lotus Fang Yuqing, who once betrayed him, and the bully Chen Zhenghao, he put aside his kindness and fought back with ruthless means. With abundant supplies, he became a paradise on an isolated island in the apocalypse. Some people fawned and begged, while others brazenly robbed him. Zhang Yi, armed with weapons and massive resources, lived alone in the frozen apocalypse, watching the ups and downs of human nature with a smile, and living as the legend of the only survivor.
