I recommend "Rebirth's Heavenly Eye Divination". This novel is a modern romance novel. After the female protagonist is reborn, she gets a heavenly book that can open the heavenly eye, control human life, and even allow beggars to get a divination.

Although it did not completely match the plot described in the question, there were still many similarities. I hope you like this fairy's recommendation. Muah ~😗
