In her previous life, Su Yunwan was humiliated by her husband, Chen Silin. After they both drowned, they were reborn at a time before their betrothal. This time, she resolutely heads to the northern frontier, honing her swordsmanship in the Gobi Desert until she becomes an exceptionally skilled female general. There, she meets Chu Jingzhou, the deeply devoted and persistent Crown Prince of Chu. Meanwhile, Chen Silin marries the Chancellor's daughter to curry favor with the powerful, seemingly climbing to great heights. In reality, he becomes trapped in a web of lies involving his inability to father a child and the truth that his son is not biologically his. When they meet again nine years later, he publicly mocks her as a 'beggar riding a donkey,' only to be utterly crushed when Chu Jingzhou declares, 'She is my Crown Princess.' In the end, Chen Silin kills his wife's family out of revenge and dies a gruesome death by the blade himself. With true love and her son by her side, Su Yunwan finally finds genuine happiness.
