Shameless Female General

Short story, first person. My sister is delicate, soft, and extremely beautiful. My father is always law-abiding, honest and simple, and has no defensiveness. But in these troubled times, such people cannot protect themselves or their families. That man gained his father's trust, won his sister's heart, and became his father's son-in-law and his sister's ideal husband. But one day he raised a butcher's knife and killed everyone in my family. My sister died of guilt and anger. I came from hell and only wanted revenge in this life. The female general who is bent on revenge kills her enemies with her own hands and travels around the world happily.
