By chance, he contracted a bad-mouthed "salted fish beast", and later met Fu Yuqing and Zhang Sandao. Lin Xiao accidentally obtained a lost mystical skill, which triggered a competition among the major immortal sects. The three of them had adventures along the way, joining sects, getting involved in sect battles and family conspiracies, and constantly turning danger into safety. As a hidden villain, Bai Yunhe affects the direction of the entire world's struggle, and eventually joins forces with Lin Xiao to fight against foreign enemies. The book is full of ups and downs and has a humorous plot, completing the growth and transformation from a small person to becoming a fairy.
