In the war between the demons and the elves fifteen years ago, the entire elves were wiped out. Bu Dian saw the handsome man in blue shirt using his body to block the fatal sword for the woman, saw the tears welling up in the eyes of the beautiful woman, and heard her sad and desperate cry. She knew that those were her father and mother, the king and queen of the elves, and she was not Bu Dian at all, but the princess of the elves - Lan Shan.
