Ancient China setting. MC most likely female, possible transmigrator or rebirth, not sure of parents situation, but within her family (either her own or other branches) there’s struggle for the wife/concubines to give birth to sons. May or may not completely translated. Gory and spoiler alert: One cannon fodder stepsister/cousin who was desperate/anxious for her mother to give birth to a son so that her place in the family can be secured (and she was sick of her mother priotizing the unborn son), when her mother had difficulties giving birth, decided to yank the baby of her mother’s womb and pulled off the baby’s hand. The baby (definitely) and mother (most likely) survived but baby boy is forever disfigured. Thanks in advance.
Yay, I've read Chu Wang Fei before. I'll reread this story within this week and put the title as solved if it's the one.
