After Being Forced to Become a Hostage in an Enemy Nation

(This novel's stats are too poor, and updating has become a frantic struggle. I'll update whenever I feel like it from now on~) Yue Suining is the unloved third princess of Yunqin. Well-behaved and dutiful, she does whatever the Emperor and Empress tell her. She only hopes that when she comes of age, they'll remember her good behavior and arrange a good marriage for her. But after Yunqin loses a war, the people of Yanchu, who have a blood feud with Yunqin, insist that the Crown Prince be sent as a hostage before they'll agree to peace talks. So the Emperor and Empress bind Yue Suining's hands and feet, dress her in men's clothes, and stuff her into a carriage bound for Yanchu. She looks seven or eight parts like the Crown Prince, after all. Three thousand li from home, danger lurks everywhere. The Empress has hated her for years and would be glad if she died along the way. The generals who favor war hope she'll die so they can use the chance to fight another bloody battle. The royal houses of Yanchu and Yunqin have a long history of bloodshed, with countless national and personal vendettas. They look at her the way wolves look at their prey. To protect herself, she swallows her pride and begs shamelessly for help, seeking shelter with Yanchu's powerful Crown Prince. She moves into his room and shares his meals and bed. Everyone says Yue Suining is incredibly lucky. Yanchu's Crown Prince, Xie Zhiyu, is as refined and bright as the moon, noble and virtuous, with the compassion of a god or Buddha. Everyone praises him as a gentleman. With his protection, her days in Yanchu are smooth sailing. Later, when the two nations go to war, someone sees Yue Suining sneaking out of Yanjing on a rainy night. The usually gentle and refined Crown Prince's eyes turn red with rage. He personally leads elite troops to block her way and grits out, "Where do you think you're going?" As soon as the news spreads, everyone assumes that with the two nations at war and the hostage having fled, the Crown Prince will surely cut off her head to offer as a sacrifice and raise his troops' morale. Those who hate Yunqin's Crown Prince wait to see her make a fool of herself. They wait and wait, until Xie Zhiyu beheads the Qin Emperor, until he unifies the thirty-six nations of the Western Regions. They wait until Yue Suining rises to the most honored position in the world, and the godlike new Emperor is right beside her, lifting the hem of her heavy skirt for her.
