Everyone in the world is afraid of the cold-blooded and powerful regent Song Mobai, but only the princess of Zhaoyang, Lin Zhi, has been indulged by him for twenty-one years, enjoying the most extreme favor in the world, running rampant and worry-free every year. No one knows that this immortal and powerful minister who is in charge of the world is actually a fox demon who has been waiting for thousands of years. He changed his destiny to protect her soul, abandoned his thousand-year journey to immortality and entered the troubled world, covered in blood and sin, just to protect her innocence and stability for the rest of her life. But rumors abound, traitors stir up trouble, and suspicions take root. In order to save his critically ill father and stabilize the country, Lin Zhi firmly believed that human beings and demons had different paths, so she personally laid a dragnet to take his fox pill and cut off his obsession, causing him to lose his soul and never return. When the wind and snow fall from the sky, the truth finally comes. She won a prosperous world and a stable family, but she personally killed the person who loved her most. From then on, the mountains and rivers were safe, and there was wind and snow every year. She was left alone for the rest of her life, and she was responsible for her whole life, with no solution to her regrets.
