A map of human skin points to Yelang, a mysterious ancient country in the southwest that "claimed to be greater than the Han Dynasty" in "Historical Records". The famous archeology professor Qin Baichuan gathered four seemingly unrelated partners, but in fact they had their own unique skills, to form a "stargazing" expedition team and go deep into the Shiwan Mountains in Guizhou.
What they are pursuing is not gold, but a terrifying truth that is covered up by "foreign objects from the sky" and "ancient witchcraft". The bone altar deep in the cave, the ghostly fire that lasts for thousands of years, the strange miasma that allows people to "see the past", and the indescribable "things" guarding the royal tombs...
As the exploration deepened, they discovered that the demise of Yelang Kingdom was not because of "Yelang's arrogance", but because they violated some taboo that should not be disturbed. Professor Qin Baichuan's true purpose and the intricate and secret connections between the five members gradually surfaced in the reflection of the underground river.
Friends, have you heard the sound of Gu bell? That voice was designed to lead the way, and also to ask for one's life.
Purpose: Through an archaeological exploration of a lost civilization, we explore the boundary between the "known" and the "unknown", showing the insignificance and unyieldingness of human beings in the face of the grand and strange historical truth, as well as the struggle and glory of human nature in extreme environments.
