Rebirth: My Alpha Drank His Own Poison

In my past life, my Alpha fiancé and his mistress poisoned me to death, stealing my status, ruining my fertility and using my family’s power to seize the throne. Reborn at our mating ceremony, I tricked him into drinking the sterilizing wolfsbane by swapping cups. I tore off the mistress’s mask, broke the engagement, and married the border war god. I exposed his baby-stealing and dark magic plot, having him imprisoned for life. This life, I protect my family and take revenge!
