On the day of the avalanche in the north, Shen Zhao recognized Su Yanqiu among the corpses - the witch who had saved his life in his previous life. He didn't know that she was the 'Son of the White Wolf' who was prophesied to kill him, and she didn't know that he was the source of her bloodline. Huo Jin, the commander of the cavalry, hid secret documents, Pei Yuan, the secret envoy of the Ministry of Household Affairs, forged account books, Bai Wujiu, the shaman priest, controlled the destiny, and Red Wolf, the young master of the prairie, vowed revenge. When the seal of the Snowfield Temple gradually opened, Shen Zhao's bloodline, Su Yanqiu's curse, Huo Jin's military power, and Pei Yuan's secret letter were four forces tearing at the dynasty's lifeline in the snow. The avalanche is not a natural disaster, but the beginning of a thousand-year ritual.
