> 1935, Dunhuang.
> Shen Qingyan, a female archaeologist who studied in the UK, stepped into the Mogao Grottoes for the first time after returning to China, and found half of an ancient Tibetan scroll that had been deliberately burned in the ashes of the Buddhist Scripture Cave. The next day, the old Taoist priest guarding the cave unexpectedly fell off the cliff, leaving only an ancient saying on his body: "The man with the ocher face wakes up on the night of the full moon."

> In order to trace the truth behind the murder of his mentor, Shen Qingyan was forced to join forces with Chen Keming, an antiquities dealer who was both good and evil, but found himself involved in a deadly game across Europe and Asia - the special envoys of the Nazi "Ancestral Heritage Society" were pressing forward step by step with the Aryan Root-Searching Order; Dao Tashi possesses the unique skills of guarding mausoleums, but his eyes hide the curse and loyalty of his tribe for thousands of years; and the "Land Without Sun and Moon" recorded in the ancient scrolls may not only contain sacred objects and wealth from the era when the Buddha was exterminated, but also an original document that could overturn the history of world religions.

> From the Yadan Labyrinth in the Devil City, to the singing whistle in the sand dunes, to the astronomical mechanism in the Xixia Beacon - every step of solving the puzzle is a gamble with death. And when the ultimate truth emerges from the murals in the underground grottoes, Shen Qingyan must make a choice: let history be used as a weapon by looters, or rebury thousands of years of secrets into the yellow sand with his own hands?
