Reborn in the womb as the only daughter of a grand marshal, she is forced into the palace to become empress. With the scheming new emperor, she goes from a brawl in the bridal chamber to a fight at court, determined to see which of them will win. She is a peerless martial artist with a fierce, unruly nature. To seize military power, the new emperor Xiao Yexun sets a deadly trap: “Accept the empress’s title and enter the capital, and you will die.” Xia Yunxiu overrules everyone’s objections and decides to enter the capital alone, planning to “bear a son, then leave the father and keep the child.” On the way, Xiao Yexun disguises himself and ambushes her, only to be beaten black and blue. The emperor and empress become sworn adversaries. On their wedding night, there is no romance whatsoever: they get into a full-on fight. The next day, both appear at court covered in bruises, claiming they were “practicing martial arts” and “just horsing around.” From then on, the harem becomes their unusual battlefield. In public, they seem deeply devoted; behind closed doors, they trade poisoned food, hidden arrows, martial challenges, and verbal volleys. Using her modern outlook and military know-how, the heroine turns the harem upside down and keeps the troublemaking consorts and court officials dancing in the palm of her hand. Consorts like Noble Consort Rong, who try to compete for the emperor’s favor, are either frightened off by the heroine’s bluntness and martial prowess or driven to a breakdown by her bizarre way of thinking. Just as the two are locked in an evenly matched struggle, a sudden assassination attempt leads them to take a fatal blow meant for the other. Only then do they realize a more dangerous enemy is lurking behind the scenes. The emperor and empress quickly reach an agreement: pause their internal war and unite against their common foe, vowing to find and eliminate the mastermind. As they join forces against their enemies, their mutual hatred gradually gives way to unexpected affection. They still annoy each other, but they also come to admire one another. In the end, their bond deepens, they stabilize the court together, and their life as bickering partners becomes both sweet and hilarious.
