[Mutual devotion + transmigrate into a book + mental powers + medical skills + revenge on scumbags]
Chi Yun unexpectedly transmigrates into the doomed villainess of The Wife Is Not as Good as the Concubine. As the neglected legitimate daughter of a marquis's household, she faces an absent, despicable father, a vicious stepmother, and a sister bent on competing with other women. She decides to seize the leading role and overturn the everyone-is-evil setup and the bad ending. Armed with modern medical skills and her mental-power golden finger, Chi Yun goes on a rampage: she empties the marquis's estate and beats the hell out of the crown prince.
When making her case: “Rounding up, I saved your life from the King of Hell. If that isn't meritorious service, what is?”
When stabbing the crown prince: “Don't mess with someone who studied medicine. I can give you 360 cuts, and not one will be fatal.”
When dealing with people who don't matter: “Sorry, my mother died young. Nobody taught me any manners.”

Entirely fictional setting, no logic required
1. The male lead is blind and no good person. He puts on an act and keeps his head down in the early chapters.
2. The female lead is her own golden finger, with mental powers as support.
