It is an idea that I got by chance: in the late Qing Dynasty, a Han girl named Nian Xinyao died with resentment. She was too resentful and could not enter reincarnation, so she had a new life. In this life, she is the non-existent Zhao Fei, a woman sent by the Mongolian tribe. She has a golden finger, and her goal is to protect the Eighth Princess and change her fate of premature death.
