After Giving Birth to an Heir to the Childless Emperor

On the day my engagement was canceled by the No. 1 Scholar, I took my parents back to my hometown, but I met the princess on the way. Relying on the fact that she was the only flesh and blood of the emperor, she not only whipped my parents to death on the spot, but also threw me into a brothel. The princess smiled innocently: Dare you compete with me for a man? Because of the princess's words, I soon contracted a disease and was burned alive in a mass grave. When I opened my eyes again, a strange voice sounded in my ears: Congratulations to the host for binding the pregnancy system. Later I changed my appearance and entered the palace as a concubine. When the princess pointed the whip at me again, the emperor, who always doted on the princess, protected my belly: evil beast! Don't be rude to your aunt!
