After My Sister Died, I Became a Female Doctor in the General's Mansion.

My sister is a maid in the General's Mansion. Birthday day. I didn't wait for my sister. What was waiting was my sister's body. They said that the sister's fiancé, who coveted the lady, was beaten to death. Later, I became a disciple of Poison Doctor Valley. Five years later, I became a female doctor in the general's mansion.
