The story revolves around Hu Bayi and Wang Kaixuan leading an archaeological team organized by Shirley Yang, venturing into the heart of the desert in search of the lost ancient city. Hu Bayi, who had previously gone through rural experiences and climbed mountains, arrives at Ganggangyingzi, a border area between China and Mongolia, carrying the only remaining book from his family, "The Sixteen-Character Yin Yang Feng Shui Secret Technique." In his free time, he diligently memorizes the words from the book. Later, he joins the military and ends up in Tibet, where he survives a massive avalanche by using his acquired secret techniques. After being discharged, Hu Bayi and his friend, Fatty, join an archaeological team heading to Xinjiang. After enduring numerous perils, they finally reach the ruins of the lost ancient city in the Taklamakan Desert and enter an underground "Ghost Cave." The cave is filled with intricate mechanisms and traps, seemingly under the control of a mysterious prophet.
