Yes, this novel was called "Imperial Beast Empress, Her Highness is Demonized Again". In the plot, Empress Youying was demonized and killed everyone after she suffered a blow. If you like fantasy novels, I recommend you to read Rebirth: The Ultimate Beast Trainer. It tells the story of a female protagonist who rewrote her name as a good-for-nothing after her rebirth. It also has unique elements of an animal trainer. It's very attractive. I hope you like this fairy's recommendation. Muah ~😗
