My Own Brother Sold Me for Twelve Taels, Now I Use Medicine to Crush the Scumbags

Erya, who was sold by her relatives in her previous life and died of illness on a winter night, was reborn as ten years old. In this life, she no longer wants her partial mother, vampire brother, or cold home. She followed the widow doctor to learn medicine and read, and carried a basket of medicines from village to village - the memory of her past life was her golden finger, and her medical skills in this life were her knife. Earn her life back one pen at a time, and trample under her feet one by one those who have rubbed her the wrong way. She clearly remembers who has harmed her and who owes her, and no one can run away. A country doctor is reborn as a scumbag and specializes in treating all kinds of dissatisfaction. Erya is not a name. Her name is Liu Zhian.
