She, the legitimate daughter of the general, was sent to the border due to the prophecy of a "disaster star" since she was a child. He, the seventh prince of Chao Dynasty, is known as the "idle prince", but he is actually very secretive. Two people who have nothing in common are bound together by an imperial edict. From a contracted couple who tested each other to an alliance of life and death, they faced the secret arrows in the court and the war on the border together. - "I don't want to besiege you in the deep palace and fight for your favor and jealousy." - "I promise you that I will only have you as my wife in this life, and we will be together for the rest of my life. I will never break my oath." —"What if I don't want to?" Yun Zhao did not want to be trapped in the deep palace, but Xiao Heng understood and supported her. The courtiers were in an uproar, and despite their secular vision, they made her the first female prince in the history of the Chao Dynasty and the governor of the northern border, taking charge of the world's troops. Before leaving, he held hands and made a covenant: "If you think clearly, I am willing to use the country as my betrothal and welcome you as my queen." Decades later, the meticulous history books recorded that Emperor Jing kept his harem empty all his life, and only stayed with the female prince from the north to keep the mountains and rivers safe.
