A survival game throws everyone into a glacial wasteland. The heroine was feeding two stray cats before traveling through time, and accidentally brought the little black cat "Coal Ball" and the golden cat "Juejue" into the game. At the beginning, there was only a dilapidated cabin and the core of a dying bonfire. She refused to join a group or accept teammates, and just wanted to live peacefully with her two cats. As survival progresses, Coal Ball awakens to "adventure and treasure hunt", and goes out every day to bring back random supplies; awakens to "sleeping to attract wealth", the more comfortable the residence, the more generous the rewards. The heroine constantly upgrades wooden houses, fireplaces, underground warehouses and greenhouses through collection, hoarding, trading and system production, and expands her own warm little home amidst blizzards, polar nights and beast tides. While others were struggling to survive, she took her two cats and turned the ice and snow into a leisurely and prosperous solitary life.
