The Most Pampered Demon Concubine: Demon Lord?

She was a demon who transformed into a human by chance, but her body was shattered by a sneeze. She borrowed a corpse and was reborn as a sickly girl in the Prince Regent's palace. However, she found that the palace was filled with murderous plots and dangers. Everyone wanted her to die. However, she had invincible charm, superb medical skills, and superb swordsmanship. With her millennium of IQ and cruel methods, she made life miserable and embarked on a counterattack. The only fly in the ointment is that she accidentally provokes a demon king who pursues her relentlessly. Feng Jiuli: "I am a demon who feeds on blood and kills people like hemp." A certain demon king immediately opened his collar and put his fair neck to her mouth... Feng Jiuli: "You are good at everything, but you are more than beautiful, but not heroic enough." A certain demon king quickly developed eight-pack abs and showed them in front of her... Feng Jiuli was speechless and said with disgust on his face: "I don't like being clingy." A certain demon king finally said with a playful smile: "Madam, please calm down. For the sake of my husband, it is difficult for me to obey my orders."
