The snow is falling in Yujing, and the fragrance of medicine is floating in the air. She is the sickly princess Yunzhao who was forgotten in the deep valley. Her medical skills can kill people, but she cannot cure her own premature death. He is Xie Lin, the powerful and ruthless king of Zhenbei in the northern border. His armor is soaked in the frost outside the Great Wall, but his heart is filled with a fatal love poison that no one can solve.
A snowstorm brought him, seriously injured and on the verge of death, to the door of her medicine house. She applied acupuncture to save her life, but she didn't realize that the person in front of her was her fiancé who had married someone else by mistake when she was young. He drank the decoction she had cooked with her own hands, not knowing that this pale woman was actually his unmarried wife who had been imprinted on his heart for many years.
When she entered the palace to cure the disease, in the wedding hall hung with red silk, the concubine smiled sweetly despite her status. She lay dormant in the body of a medical girl, visited the imperial mausoleum at night, and conveyed love at the beacon fire. In the whirlpool of conspiracy and lust for power, she and he were startled every step of the way, and their love secretly arose.
When the plague turned into a butcher's knife for her concubine and foreign enemies, she cut out her heart's blood and dyed her black hair with frost and snow in exchange for a cure for the world. He was so angry for her that the sky was on fire, his iron cavalry trampled through the city, and he only wanted her to survive in the sea of blood.
Her life experience came to light and she turned out to be the pearl left behind by the enemy country. The family and country are at odds, and there is a dilemma between love and hate. He abandoned the king's title, threw the military talisman, took her bloody hand, and went to the vast wind and sand outside the wall together. From then on, thousands of miles of rivers and mountains were conquered, and only one peach garden was built for them.
