The Crown Princess Is Naturally Pregnant

I was born pregnant, but my whole family regarded me as a freak because of my plump figure. My twin sister bullied me like a beast because of my slender figure, and my biological parents even treated me like a slave. Later, my sister and I entered the palace at the same time and married two princes. The prince my sister married was not congenitally gifted and could not conceive her. But the second prince I married turned out to be very handsome. After three years of having two children, the father ascended the throne and became the emperor based on the son's superiority. My sister was jealous and burned me alive on the day I was crowned queen. When I opened my eyes again, I went back to the day before I entered the palace. This time, my sister wanted to marry the second prince first and wanted to marry my mother to the world. I laughed. The second prince has a truly incompetent constitution. Not only will his sister not be able to have any more children after she marries him, but she will also be treated as a plaything of eunuchs...
