The Crown Prince Betrayed Me? I Turned Around and Married the Emperor’s Uncle!

[Household intrigue + scumbag’s agonizing regret + twists + second male lead takes the crown + transmigration into a book] Meng Wantang, a military doctor from the 21st century, transmigrated into a book. She became the marquis’s disfigured legitimate daughter, believed to be cursed and destined to bring disaster to the whole family. The Crown Prince, who had been her lover for years, wanted to break their engagement while keeping his good name, so he arranged for someone to rape me? I’ll tear apart that scumbag’s hypocritical facade and ruin his reputation! My scumbag father favors his concubine over his wife and lets his illegitimate daughter walk all over me? I’ll expose him in public: he can only perform in bed because his concubine drugs him! My treacherous maid thinks I’m helping her marry a general? I’m not that kind. A traitor deserves an abusive, twisted husband! The Crown Prince and my half sister mock me as an ugly spinster who’ll never marry? I’ll use my medical skills to heal my scars, dazzle the whole capital, and marry the God of War, my uncle by marriage, in a grand public wedding! After we marry, I kill people, the prince hands me the knife, I wipe out entire families, depose the Crown Prince, and reach the pinnacle of power!
