The only daughter of a generalissimo who was born through pregnancy was forced to join the palace as a queen. She fought with the sinister new emperor from the bridal chamber to the court, vowing to fight with your daughter. She has superb martial arts skills and a strong personality. In order to withdraw his military power, the new emperor Xiao Yexun set up a dead end situation of "if you are canonized as a queen, you will die if you enter the capital". Xia Yunxiu went against all opinions and decided to go to Beijing alone, with the idea of "getting a male to give birth to an heir, leaving the father to keep the son". On the way to Beijing, Xiao Yexun disguised himself to intercept and kill him, but was beaten by Xia Yunxiu until his nose was bruised and his face was swollen. The emperor and the empress were at odds with each other. On the wedding night, instead of being charming at all, the two got into a fight. The next day, they both went to court with their wounds, claiming to be "experiencing martial arts" and "playing". Since then, the harem has become a different kind of "battlefield" for the two of them. On the surface, the emperor and empress are deeply affectionate, but behind the scenes, there are swords and poisons, cold arrows, martial arts, and verbal abuse taking turns. The heroine relied on modern thinking and military wisdom to stir up chaos in the harem, and manipulated the concubines and court ministers at her fingertips. Concubine Rong and other cannon fodder who are trying to compete for favor are either frightened away by the heroine's straight shots and force value, or are driven to mental breakdown by her strange brain circuitry. Just when the two were fighting inseparably, a sudden assassination caused each other to accidentally block the fatal blow for the other. Only then did the two realize that there was a more sinister hand behind the scenes. The emperor and the empress quickly reached an agreement: to suspend the civil war and unanimously deal with the outside world, vowing to find and eradicate the people behind it. In the process of joining forces to fight against the enemy, they gradually developed different feelings from mortal enemies. They disliked each other and admired each other. In the end, the relationship between the emperor and the empress gradually deepened, and they worked together to stabilize the court, staging a sweet and hilarious daily life between enemies.
