Cui Yunshu, a modern doctoral student of traditional Chinese medicine, wakes up as the legitimate daughter of the Qinghe Cui clan, the foremost of the Five Great Surnames and Seven Noble Houses.
The north and south are locked in a standoff, while powerful clans vie for dominance. She had hoped to use her medical skills to protect her family and help the people, living a quiet life. But during a chance encounter in Jingkou, Xie An, the legitimate son of the Xie clan, sets his sights on her. With a face like jade and a figure like a green bamboo, he is hailed as the most elegant gentleman south of the Yangtze. Beneath his gentle exterior, he advances at every turn, offering her a jade pendant and making a thousand miles feel like mere steps.
She offers free medical care, and he secures medicine. When she falls ill in an epidemic, he vows to stay by her side unto death. He pursues her from Dongshan to the imperial court, from refined philosophical debates to a land engulfed in war. He offers her an empire in exchange for her promise to stand by him in life and death.
During the Battle of Fei River, he directs the campaign while she saves lives behind the scenes. When victory is won, he takes her into seclusion on Dongshan, fulfilling their promise to grow old together among the green hills. Here you will find the spirit of the Wei and Jin dynasties, and a devotion deeper than any other.
