Wu Xie's five years of peaceful life were interrupted by Jin Wantang's sudden visit. Jin Wantang actually knew that the scorpion pattern on the moonstone brought out from the Zhang family's ancient building was related to the childhood stuffy oil bottle.
In order to pursue clues, Wu Xie went to Nepal and then to Medog, Tibet. In Medog, various clues related to the oil bottle are pouring in! Things got out of hand. Wu Xie got Menyou Ping's notes from the lama of Jila Temple and learned the causes and consequences of Men You Ping's entry into the snow-capped mountains. What shocked Wu Xie was that he saw "The Limit of the World" in another notebook - there was another giant bronze door in the hinterland of the vast snow-capped mountains!
People from all walks of life gather at Jila Temple. Is this a coincidence or is it deliberately arranged? What does the mysterious scorpion mean? What exactly are "the limits of the world"?
Why is Wu Xie the only person who can save the Zhang family? Are the Hong Kong Zhang family trustworthy? Are they plotting evil or completing their mission?
This is a brand new journey. Wu Xie and Fatty follow the footsteps of Menyou Ping into the hinterland of the snowy mountains. This time, can Wu Xie solve all the mysteries?
