Jueshi Shenyi: Fuhei Daxiaojie

A young medical prodigy was imprisoned by her grandfather and later escaped, only to be transported to another world. There, she becomes the Duke's family's dominant yet useless eldest daughter, mocked for lacking a spirit familiar and tormented by her fiancé. Despite her circumstances, she wields acupuncture needles and refuses to aid those on the brink of death simply because they ask. She also rejects advances from those she has saved, even if they attempt to repay her with their bodies.
