My Half-Sister Stole My Top Scholar, So I Happily Take Her Fate as Empress

In my past life, my third sister poisoned me to death. My husband watched with cold indifference, while my mother-in-law personally forced poisoned wine down my throat. Reborn on my wedding night, I tied the jade pendant that had once pledged our love around my third sister's waist with my own hands. "Dear sister, you can have all this fortune and glory. Your elder sister is giving it to you." Later, screams rang out night after night from the Number One Scholar's manor, and people began saying that its mistress had gone mad. My third sister smiled as she handed me a secret letter. "Elder sister, I've been giving my husband medicine for days. I'm afraid he doesn't have long to live." "I also ‘broke’ my mother-in-law's leg. Who should be next?" Next should be... you. Later, the whole court cursed me as a heartless, venomous woman. Leaning against the new emperor, I toyed with his jade seal and smiled. "This is only the beginning. My revenge... goes far beyond this." The new emperor smiled. "Next time you kill someone, my dear, remember to let your husband hand you the knife."
