The extremely cold apocalypse is coming, Fang Xiaoyu died and was reborn, returning to the day when the beasts were assigned! I originally wanted to take back my white bear partner from my previous life, but the green tea squad leader forcibly gave me the "trash" white fox, and was also forced to conclude a blood contract of life and death. What's even weirder is that both the squad leader and White Bear were reborn! She thought that by snatching the white bear, she would be able to control the cold-resistant talent, but she didn't know that the white bear was a vengeful Shirogiri Kuro, and the seemingly useless white fox also hid a surprising secret. The fight for supplies, reversal of contracts, survival in the apocalypse, and the chess game of revenge has already begun, but why does the mysterious power awakened by the white fox make the entire apocalypse tremble?
