The daughter of the Xu family, named Xu Fei, has been frail and sick since she was a child. She has been taking soups and medicines all day long. Except for one day when she accidentally entered the study of her third brother Xu Jun and saw books about martial arts and swordsmanship, she became addicted to them. This made her boring life a little fun. After reading many books, she admired the Huashan School's swordsmanship the most. The swordsmanship of the lightning-fast and powerful swordsmanship moved her heart, and she came up with the idea of learning swordsmanship. When she thought she could finally realize her dream of being a hero when she arrived at the foot of Mount Hua, unexpectedly, contrary to her expectations, she came to the blessed land of immortality - Changbai Mountain. In her subsequent life, there were many more arrogant masters - Yunmo, senior brother Bingkuan - Yuanyuan, a playful and naughty senior sister - Mutong, and a charming shark - Xuanmeng.
