Su Qingyuan, a graduate student in the Department of History, traveled through the Prime Minister's Mansion and was humiliated as a concubine. Her mother died young and she was bullied by her aunt and sister. When she was trying to survive in Hanyuan, she awakened her memory and the secret of the lotus jade pendant, and vowed to change her destiny against the will of heaven. At the Lantern Festival Palace Banquet, she stunned the audience with a poem "Lanxiao" and was awarded the title of County Lord, breaking the fate of a concubine.
During the disaster relief in the south, she offered three strategies to resolve the crisis; when the prince seized the throne, she and the seventh prince Xiao Yu knew each other and cherished each other, and worked together to defeat political opponents and help Xiao Yu ascend to the top. After becoming the Crown Princess, she resolved the harem's plot; when Xiao Yu ascended the throne, she used her dignity as a queen to assist her husband in creating the "Yongxi Prosperity", promoting reforms and stabilizing the country, and was known as the "Eternal Wise Queen". From being an abandoned daughter in the Hanyuan to being the mother of the world, Su Qingyuan relied on her wisdom and tenacity to play step by step in the game of deep house and court. Not only did she complete a personal counterattack, but she also joined hands with Xiao Yu to protect the prosperity of Dajing, and wrote an eternal story of love and responsibility.
