Bai Luoyan, a reckless little butterfly, flew to the human world when she was a child. A child saw her and had her wings pulled off. So Bai Luoyan kept remembering her childhood hatred. Finally, her hundreds of years of practice finally bore fruit: she became the leader of the Butterfly Clan, Han Zun, one of the ancient demon lords. With her current skills, could she still be unable to beat that child back then? Bai Luoyan proudly imagined that she went down to earth and chatted happily with a young lady named Su, and asked Miss Su to take her back and pretend to be her missing sister. Miss Su readily agreed to Bai Luoyan's request. They were indeed best friends! Then it happened that the sister of the Miss Su family was about to marry a prince, but the real eldest daughter of the Su family disappeared. This made Bai Luoyan particularly distressed. If she had known about it, she would not have let her best friend bring her back. However, on the wedding night, Bai Luoyan discovered that the prince was the reincarnation of that child!
