My Aunt Replaced My Mother's Son with a Freak

My mother and aunt gave birth on the same day. My mother gave birth to a freak, but my aunt gave birth to a lively and healthy fat boy. My father threw the baby to death in a rage, my mother was abandoned and went crazy and ended up on the street. I also changed from the legitimate daughter of the Marquis to a virgin in the Virgin Hall. When my mother died, my aunt held the child and stepped on her mother's bones with great joy. "This is your child, but he will only recognize me as his mother." Only then did I know that my aunt, who was a royal concubine, took Xiji Pills to fight for favor, which caused the fetus in her belly to be deformed. In order to help her retain her favor, my father and grandmother did not hesitate to kill her mother. My aunt was successful in giving birth to the emperor's eldest son, and was named queen, enjoying great fame. My father also married another aunt, and the whole family was happy. When I opened my eyes again, I went back to the day when my mother gave birth.
