At the end of the Qing Dynasty and the beginning of the Republic of China, warlords were raging in southern Xinjiang. In order to avenge his family's blood feud, Qin Mu, the captain of the Mojin School who became a monk on the way, broke into the Miao territory of Leigong Mountain and formed an alliance with Aman, the last descendant of witchcraft in Miao territory. In mysterious places such as the Bo people's hanging coffins, abandoned Gu palaces, and ancient salt passages, they encountered the Gu woman's pursuit and the mandrill's curse, and solved millennium mysteries such as the female ghost in the Luohua Cave and the code of the Classic of Mountains and Seas. With the emergence of the underground palace of Yelang Prince's Tomb, the Gu mother and the mandrill mutated, which also led to the conspiracy of the Japanese forces. When the secrets of the fragments of the Book of Gu and the Black Water Styx Map were revealed, a legend of the Southern Barbarian civilization that spanned thousands of years was thrillingly staged in the dangerous secret realm of the Miao border.
