In order to protect the country of Dayu, Su Lanxin sacrificed herself and fell off a cliff. Her soul was damaged and she lost her memory and lived in Dayin. Emperor Yu Shinan of Dayu lost his true love and left his harem empty for three years to find his wife. Zheng Hao, the prince of Dayin, met her wandering by chance and guarded her silently for three years, pursuing his wife tenderly every step of the way.
Su Lanxin, who had lost her memory, was adopted as an adopted daughter by the King of Zhenbei and became the favorite of the royal family. With her medical skills and talents, she counterattacked and became the first-grade princess of Dayin. Yu Shinan came across the border, willing to hire Yu the country, and the two kings seized their wives and swept across the two countries.
The ancient temple was in crisis, and Zheng Hao risked his life to protect it, but no one knew about it. The heroine's memory gradually recovered, she faked death and retired, and returned to the world as the young leader of the Wanxian Alliance. When the whole truth was revealed, she broke through the old dreams and chose Zheng Hao to stay with her for three years. Together, they calmed down the world and achieved a happy life.
