My Family Stole My Military Achievements, So the Reborn Legitimate Daughter Slaughtered Them All

[Revenge After Being Reborn] [General's Daughter] [The Whole Family Pays, But She Won't Forgive Them] [Fake and Real Heiresses] I disguised myself as a man and joined the army in my father's place for ten years, earning glorious military honors. After the war was over, afraid that my disguise would be exposed, I had no choice but to fake my death, resume my identity as a woman, and return to the capital to reunite with my family. Who could have guessed that my family, afraid I would bring them trouble, had already raised a new daughter? My father said, "You disguised yourself as a man to enlist. That's a crime of deceiving the Emperor. If it comes to light, it'll get the whole family killed." My mother said, "As the eldest daughter, you must endure what you can. That's your fate."

He said I don't look like my brother at all. Mother, I'm scared. What if Prince Ning sees Elder Sister...?" My mother's face immediately went deathly pale with fright. That day, my mother broke from her usual coldness and gently offered me a cup of wine to celebrate my birthday. Moved, I drank it in one gulp. When I woke, I had been poisoned mute, all ten fingers broken, and my martial arts cultivation destroyed. They had gone to such lengths to steal my military achievements, all to pave the way for their adopted daughter. The glory I had won by risking my life had become my death warrant! When I opened my eyes again, I had been reborn on the very first day I returned to the capital after faking my death...
