Transformed into a Female-Centric Novel’s Cannon Fodder: From Death Row to Sword Goddess

[Transformation + Strong Female Lead + Ruthless + Satisfying Read + No Gender-Swap Marriage + A Hint of Yuri + Overpowered + No Hidden Power Suppression + Not a Do-Gooder] Ye Xuan transmigrates into a high-martial world as the neglected, bullied legitimate daughter of the Ye family. Her father ignores her, her mother is gravely ill and bedridden, and her stepmother mercilessly torments the mother and her three daughters. Their status is even lower than the servants'. The original Ye Xuan thought that if she worked hard and gave everything for the Ye family, her father would finally notice her. Instead, on the day of the martial arts exam, her wicked half-sister, Ye Xue, drugs her. Ye Xue intends to offer her up to the wastrel heir of the Liu family, making her a sacrificial pawn so the Ye family can curry favor with them. Ye Xuan, who has just transmigrated into her body, promptly castrates and kills him with a single strike! She thinks she is doomed, but unexpectedly receives the status of a death-row prisoner. If she goes to the front lines, kills ferocious beasts, and earns military merit, her crimes will be offset and she can regain her freedom. Ye Xuan immediately cuts ties with the Ye family and takes her frail mother and younger sister to seek refuge with the military! On the way to enlist, she awakens the God of Slaughter System. On her very first day in the army, she faces a beast tide alone! At the military district tournament, she carves through the entire district with a greatsword, thrashes the Liu family's prodigy, and stuns the military bigwigs, who scramble to take her on as a personal disciple! Beyond Shanhai Pass, she defends the nation's gates alone with her sword against a beast tide of hundreds of millions, striking fear into every direction! When seven kingdoms invade, she races thousands of miles with her sword to wipe out a hundred thousand rebels! Gradually... Why are the people who once looked down on her starting to act so strange? The God of War's son confesses his love in public? The peerless God of War is writing her love letters? No, thanks! What? The Liu and Ye families have been exposed for plotting rebellion and defecting to the enemy? Leave that to me! When Ye Xuan's father realizes there is no way out and disaster is at hand, he looks up at her, standing in the void like a god of slaughter, and begins to weep and beg for mercy? “Sorry, what does the death of your Ye family have to do with me?”
