You Blame Me for Climbing the Social Ladder? My Lord, I Did It All for You

[The heroine is reborn to torment her enemies + the hero steals her from another man + the second male lead chases his wife to the crematorium] There isn't a single decent person in the Duke of Luo's household! Her father-in-law treats human lives as nothing and takes bribes; her mother-in-law is sharp-tongued and greedy; her sister-in-law is spoiled, domineering, and cruel. Her husband, Luo Linyan, married her as part of a scheme for the woman he loved, even sending her to the Regent's bed to clear his path to power. Reborn, Chu Xizhi finally sees the truth: a woman can rely on no one but herself. This time, she won't be a virtuous wife or a dutiful daughter-in-law. She'll be a vengeful demon who claims lives! Her scumbag husband wants to elope with his true love? She brings every noblewoman in the city to catch them in the act. Her wicked mother-in-law wants to swallow her dowry? She produces five years of account books and empties the Duke's household, down to the last coin, with interest. Her sister-in-law resents her for stealing the spotlight? She destroys her reputation, making her the laughingstock of the capital. Retribution descends on the Duke of Luo's household. Some die, others go mad, and the whole family kneels and begs for forgiveness: "Xizhi, we were blind back then!" But Chu Xizhi never looks back, because someone already cherishes her like a treasure. The Regent, once powerful enough to command the court, now sits on the Dragon Throne and pulls her into his arms: "Anyone who hurts her dies!"
