The Noble Daughter's Alluring Beauty: Poisoning the World

In her previous life, she was foolish and naive, taken in by a scoundrel's sweet words until she was completely under his thumb. Only as she lay dying did she learn that her so-called husband had married her solely for her status as the legitimate daughter. It was only when she watched him smash their swaddled baby to death that she realized all his so-called affection had been a lie. She had thought her half-sister was the one who treated her best. She never imagined that the woman was actually the wicked one, with a heart as venomous as a snake's. She thought she would never be able to avenge herself, but Heaven took pity on her and gave her a chance to live this life again! In this life, she will make that vile man and woman pay for their crimes. She will repay them many times over for all the pain they caused her! But why does the mysterious prince, that devilishly handsome man who was always at odds with her in her previous life, now dote on her so completely? He stands above everyone else, yet gives her his whole heart, cherishing and loving her in exchange for her wholehearted love. They will join hands for a lifetime, their devotion never changing.
