"The Phoenix Flies in the Forest: The Rebirth of the Fire Phoenix Concubine" met the requirements of the title. The first chapter was about the female protagonist giving birth to a child in the palace, but the child was premature. Because she poisoned the traitor during her short pregnancy, the child had no chance of survival. In order to force the female protagonist to hand over the Flying Arts, the prince ordered the child to be killed. After the female protagonist learned about it, she was filled with grief and indignation and decided to take revenge. I hope you like this fairy's recommendation. Muah ~😗
