My family has only passed down the secret technique of male transformation for generations. It can transform a female fetus into a male, but the price is that it will not survive until thirty. And I am the only exception. To save my mother, I used forbidden magic for the first time. However, she was imprisoned by the emperor and became a royal reproductive tool. In the palace of conspiracy, only the Third Highness can give me warmth. We save each other and work together to avenge each other. On the day I ascended the throne, I wore the wooden hairpin he carved with his own hands and abolished the evil spell that killed him and trapped countless women.
