On the first day of school, the school distributes spirit beasts according to their grades. The monitor who was number one in the grade chose the SSS-level Sky Demon Silver Snake without hesitation, while I, who was ranked last, only got an F-level black bear. But the extremely cold apocalypse suddenly came. Having formed a contract with the black bear, I share the talent of being able to withstand the cold. The squad leader's silver snake, which was of noble blood but had no time to grow, froze to death on the first day. Out of jealousy, the squad leader and his classmates attacked us and even cooked bear meat hot pot in front of me. I fell into the wind and snow with hatred - and when I opened my eyes again, I was back to the day I chose the spiritual beast. This time, the monitor took the lead and said, "I'll give you the white snake, I want the black bear."
