The granddaughter of Lord Yonglin, He Lan Mingyu, has been intelligent since childhood. As a teenager, she unexpectedly met the Ninth Prince of Shengzhou, Xiao Chengxu, and the two connected deeply, developing feelings for each other. News of Xiao Chengxu's "death in battle" was mistakenly reported, and to save Chengxu's younger brother, Xiao Chengxuan, Mingyu was forced to marry Chengxu's older brother, King Xiao Chengrui of Shengzhou, becoming trapped in the palace. Xiao Chengxu achieved numerous military victories to help Xiao Chengrui ascend the throne, establishing the Great Sheng Kingdom, but due to his remarkable achievements, he aroused suspicion from Chengrui. Additionally, after learning the truth about his mother's death and his father's abdication, Chengxu resolved to usurp power and seek revenge. Before he could act, however, Xiao Chengrui unexpectedly succumbed to a long-standing illness and decreed that Mingyu's son, Xiao Qiyuan, should succeed him to restrain Chengxu and stabilize the court. Chengxu was forced to support Xiao Qiyuan but remained determined to marry He Lan Mingyu. Meanwhile, as Qiyuan grew up, he became dissatisfied with Chengxu's control and, incited by others, learned of his mother's affair with Chengxu, harboring resentment toward them both. He Lan Mingyu, valuing the stability of the Great Sheng, strove to find a balance between Qiyuan and Xiao Chengxu. Unexpectedly, Chengxu eventually died in battle, and Qiyuan also fell victim to unrequited love, passing away alongside his favored concubine, Dong Ruoxuan. For the future of the Great Sheng, Mingyu once again stood strong beside the newly crowned young emperor.
