Bailian Fake Daughter Wants to Replace Me

I worked as a traveling doctor in remote areas for ten years, living in a village and sleeping in a coffin. I thought I would only be able to deal with the corpses of patients for the rest of my life, but unexpectedly, a carriage took me back to the Prime Minister's Mansion. Only then did I realize that I was the biological daughter of the then Prime Minister who had been betrayed. The fake daughter who took over my identity blamed herself and cried: "If it weren't for me, my sister wouldn't be like this. It was me who stole my parents' favor. I'd better leave the prime minister's house!" But I knew that she wanted me to leave her and worry too much. I have no interest in the favor of my parents and brothers. There are countless rare medicinal materials in the capital, no one would be a fool not to use them!
