I Guarded the Border for Three Years, Only to Be Scorned Upon My Return

(Historical romance + face-slapping + punishing scum + political machinations + the fate of the nation) Yun Xi is the second young lady of the General's household. She took her sick father's place and went to guard the frontier for three years in place of him and her injured older brother! When she returned home to the capital, her father, mother, and brother all began to look down on her! Everyone doted on the newly arrived youngest daughter, Yun Jiao, and even her fiancé wanted to break off their engagement! The clan leader expelled her from the family clan! Fine! If that's how you want it, don't regret your decision today! Yun Xi knew that crying wouldn't help, so she turned and left at once! Repeated assassinations and frame-ups left Yun Xi with no choice but to question her origins and the cause of her grandfather's death. Whenever danger arose, the young duke, Xie Chang'an, would appear at her side to fight alongside her. He did so at the frontier, and he did so again when she returned to the capital. Together, they would eliminate treacherous ministers and pacify the four borderlands... Xie Chang'an: "Yun Xi, keep moving forward. I'll always be by your side!"
