At the beginning of school, spiritual beasts are assigned based on grades. The school belle takes away the three-tailed civet that belongs to the male protagonist and replaces it with the sky-swallowing python that no one is optimistic about. The end of the world is coming, and the school belle plots against the male protagonist, who unexpectedly enters into a life-and-death contract with Tun Tian. Lingyue secretly helps the male protagonist convey spiritual power and inform the story, but the school beauty spends all her wealth and fails to raise the spiritual beast. In the later stage, Tuntian awakens and transforms, and joins forces with Lingyue to expose the conspiracy of the school beauty and end the extreme cold apocalypse. The male protagonist lives in seclusion with two spiritual beasts.
