She is Mu Bingxuan, the daughter of General Mu of Jiang Yuguo. She replaced Jiang Zhixin, the princess of Jiang Yuguo, and married Xuanyuan Lingfeng, the prince of Fenglingguo who was famous for his cruelty. She was a princess, but she was used by the prince as bait to lure the enemy; she was married into the palace as a princess of a country, but she was treated with the lowest dignity by the prince; she was a princess who was married on behalf of the prince, and she was charged with the mission of assassinating the emperor of the enemy country.
Therefore, it's okay to serve the prince's concubine as a princess; it's okay to be bullied by the servants, but don't think that she, Mu Bingxuan, is a sick cat. Since giving in blindly will only make people push forward, she doesn't mind showing off her power and letting everyone know who she is, Mu Bingxuan!
