The Abandoned Daughter Reborn as the Crown Prince's Divine Physician

(This novel is complete, so feel free to dive in.) A medical doctor is reborn in the body of the Prime Minister's legitimate daughter, now an unwanted girl. It doesn't matter that her father doesn't care for her and her mother doesn't love her: with a silver needle, she saves the dying again and again. What's so special about injections and IVs? With a scalpel in hand, she can go anywhere. She cuts throats and opens bellies, performs brain surgery and mends bones. With astonishing medical skill and ethics, she wins over the court, earns the Emperor's favor, and gains the people's support. The Crown Prince takes a liking to her, and her influence becomes unrivaled. When her cheap father comes to claim her, she faces him coldly. She refuses to acknowledge her ancestors or return to the family clan.

You were the one who abandoned me. So be it. Now you want to use family ties to coax me back? A daughter isn't someone you can claim whenever you feel like it. My heart has gone cold. I'm leaving. Get lost, Dad!!
