Luffy's Devil Fruit Possesses Me: I Run Wild in Ancient Times

The State of Jin has a rigid, harsh hierarchy of slaves, commoners, aristocrats, and royals. King Ye Shang's mother was a commoner, so he was doomed to face prejudice from birth. In six years, he was engaged four times. Three fiancées fled, took their own lives, or threatened to die rather than marry him. Then Xu Yihuan, a modern-day slacker who stayed up all night binge-watching dramas, suddenly died and transmigrated. The moment she woke up, Xu Yihuan found herself with Luffy's rubber Devil Fruit powers from One Piece, as if the door to her destiny had opened once more. Ye Shang thought he was no longer cursed to bring death to his wives. Xu Yihuan thought she had hit the jackpot: a battle god for a fiancé, won for free. She picked a fight and became a commandant; she threatened a county magistrate during a war and ended up with a “great treasure” worth more than a kingdom... In the end, the two discovered that their birthright was a curse and their very existence a sin. Even their own fathers were ashamed to have fathered them and wanted to purge their bloodlines. Rebel? Kill their fathers? If they didn't like it, they could fight back!
