When the "forbidden zone map" left by ancient civilization appeared, Chen Mo, a down-and-out restorer of ancient books, discovered that what he wanted to explore was not a tomb, but a prehistoric relic that humans could not understand; what he had to fight was not just his peers, but doomsday maniacs who tried to steal miracles and reshape the world.
Chen Mo, an ancient book restorer, is responsible for the incomplete inheritance of the long-lost "Guanshan Taibao". He wanted to live a stable life, but was involved in a shocking whirlpool because of a mysterious star map left by his grandfather. In order to seize the secrets in the map, the overseas mysterious organization "Netherworld Society" kidnapped his close relative and forced him to lead the way.
In order to save his relatives, Chen Mo had to team up with Wang Ke, a genius geologist who was convicted of a crime, and Zhang Qingcang, a descendant of the Baobao Man whose life experience is a mystery, to form an expedition team that seemed incompatible but had complementary abilities.
According to the guidance of the star map, their target is the Jiuyou Xuan Palace, which is said to be located at the "junction of Yin and Yang". However, they soon discovered that Xuan Palace was not the mausoleum of past dynasties, but a prehistoric city suspended upside down in a huge earth vein cavity - an ecological ark and observation station left by the "Hidden Yao Civilization". The palace is suspended, and the dragon skeleton is the core. What is buried here is not gold and silver jewelry, but the truth of the "civilization filter" that can rewrite human history.
But the danger goes far beyond that. Situ Tian, the leader of the "Netherworld Society", does not seek wealth, but attempts to activate ancient devices to achieve his crazy private wishes. This move will trigger a global earth-line disaster. At the same time, various forces such as the International Archaeological Union and the mysterious Tomb Keeper Organization also intervened, turning this expedition into a cruel battlefield of multi-party games.
