I Am a Ruthless Character

Guan Ronghua was originally the eldest daughter of the Zhenguo Duke's palace, but because her biological mother died of illness when she was two years old, her father married her stepmother and was sent to the countryside to be raised in Zhuangzi. Fourteen years later, Guan Ronghua was brought back to the Imperial Capital because of her engagement to Prince Jing's son, but instead of getting married, she wanted to give up the engagement to her half-sister! As a result, Guan Ronghua became the target of humiliation and ridicule by everyone in the imperial capital. However, I never thought that not only would she remain calm and disgrace her fiancé and sister, but she would also turn around and hook up with the Sixth Prince, the most feared evil god in the capital! "What's the use? She's just a maid who treats patients and takes medicine. There are so many imperial doctors in the capital, but they haven't removed the poison from the Sixth Prince. Could it be that she still has the ability to reach heaven?" Haha, unfortunately, she has this ghost hand, which can detoxify and cure all diseases. My fiancé is regretful, the Sixth Prince is constantly doting on me, and countless knights and knights from all walks of life are coming...
