Rebirth of the Black Princess

In his previous life, just because he said that we would grow old together in this life, he helped him ascend to the throne at all costs, and even threatened his grandfather with death to use military power to protect him. In the end, his entire family was executed. In her next life, she would never let what happened in her previous life happen again. She wants to use her medical skills and lessons from her previous life to change everything, protect her grandparents who love her, and kill the scumbag Green Tea with her own hands. Little did she know that in this life she was entangled with the current Ninth Prince... This novel and its characters are purely fictitious.
