Hai Lanchi, the direct princess of the grassland, was good at riding horses and martial arts, and was knowledgeable in medicine. However, she unexpectedly embarked on a marriage journey and married into the Northern Wei Dynasty and became the princess of Xiao Yiheng, the third prince. She didn't know that this marriage was just a pawn used by Xiao Yiheng to seize the legitimate heir. On the surface, he loved "White Moonlight" concubine Su Qianran, but in fact, he was taking advantage of her. Su Qianran repeatedly made things difficult for Hailanchi because she was superior to her, but she didn't know that this prairie princess was never a soft persimmon and fought back forcefully every time.
During the confrontation, Xiao Yiheng was gradually attracted by Hailanchi's fierceness. Hailanchi also developed a secret love after saving his life. The sweetness in the early stage hid the crisis. However, under the temptation of the imperial power, in order to seize the crown prince's position, Xiao Yiheng used the emperor's order to conquer Rouran (Hailanchi's mother clan) and lured her to go with him by "returning to his hometown for fun", but she was allowed to witness the tragic death of her loved ones.
The hatred of the country and the family completely tore apart love, and Hailanchi turned from love to hatred. After Xiao Yiheng became the crown prince, he imprisoned her for eight years in an attempt to save her, but he didn't know that Rouran's old army had been reorganized in the hands of Hailanchi's brother Hailanba. Ten years later, when Rouran's army came to the Northern Wei Dynasty, Hailanchi broke free from prison and rushed to the battlefield. In front of the two armies, he committed suicide in the dilemma of love and family and country. Xiao Yiheng finally ascended to the throne, but he was left with a lifetime of regret and loneliness.
