After My Rebirth, My Sister Took Away My Pregnancy System

In the last life, my sister chose to be bound to the beauty system, while I chose the good pregnancy system. My sister took advantage of her beauty to marry the General God of War whom she had long admired. But within a month, the general died in battle, and she became a widow of a widow with no beauty. In the end, she was kidnapped and tortured to death by lustful men. And I was selected by the emperor because of my natural pregnancy. I gave birth to eight children within three years of entering the palace, and successfully ascended to the throne of the queen. My sister was so jealous that she regretted choosing the wrong system. After her death, she used her remaining soul to drag me into the water, causing me to drown. When I opened my eyes again, I was back to the day I chose to bind the system. This time, my sister chose the Good Pregnancy System without hesitation and said to me with a smile: "Sister, I've given this beauty to you, but you have no other choice but to enjoy it." I knew at that moment that she too was reborn.
