Reborn as the Legitimate Daughter, and a Huge Grudge? Thanks for Asking

[Rebirth + revenge + punishing scumbags + satisfying read] She was the legitimate daughter of a marquis's household, but she was separated from her parents as a child. Her own family abandoned her in the countryside, where servants beat and humiliated her, until her reputation was ruined and she was married off to a scumbag. Her family and husband leached off her until she had nothing left, then tortured her to death... Reborn, she returns with a pocket dimension and a System! Keep providing for the relatives who abused her? Not a chance! Her white-lotus half-sister schemes to ruin her virtue? Let her own trap be her undoing, even if she has to cry about it! The scumbag begs to get back together and share the empire with her? Thanks, but no thanks! May you and your white-lotus half-sister be bound together forever, childless but blessed with a houseful of descendants! As long as the legitimate daughter stays focused on punishing scumbags and slapping faces, the little villains will soon be left with nothing but a broken family! Everything is going according to plan! Except that the sickly prince, who died young in her previous life, seems a little different! She chops people up, and he hands her the knife! She kills, and he buries the bodies! Weren't you supposed to be dying soon?!
