Feng Huanchao: the Good-For-Nothing Eldest Lady

A female killer in the 21st century actually traveled through time and became what everyone calls a good-for-nothing lady. When she woke up, she was completely changed? She tore apart evil girls with her own hands, brutally tortured scumbag men, harvested ancient mythical beasts, and instantly became the most elusive genius girl in the capital, with a cold-faced prince protecting her. "My lord, the princess beat the princess!" A certain prince put down his tea cup and suddenly panicked. "Is the princess okay? Does your hand hurt from the beating?" "Your Majesty, the Crown Princess said that the Princess is too arrogant and asked you to take charge of her!" A certain prince roared angrily instantly. "My princess can do whatever she wants. If she dares to speak arrogantly again, I don't mind letting her be deposed together with the prince!"
