After Rebirth, My Sister Replaced Me with Affinity and Became the Imperial Princess.

My affinity level is as high as ninety-nine, the highest in interstellar history. The higher the affinity factor, the higher the mental power of the child born. In this interstellar world where the strong are respected, everyone wants to marry me. In my previous life, I married the prince of the Interstellar Empire, and all the boys I gave birth to had S-level mental abilities. I am also known as the "First Lady of the Stars." However, my compatriot sister finally married an old man because of her low agreeableness and no one cared about her. I took pity on her and took her away from the old man, but I didn't expect that she would be jealous and kill me with a gun. After rebirth, my sister exchanged our avidin with ancient magic. She said proudly: "Sister, this time it's my turn to be the first lady of the interstellar world." And when I saw the number on the monitor showing zero, I cried with joy. I no longer have to be a sow in this life.
