This is a story that happened to several young people on a university campus. They are students majoring in unpopular archeology and came to the mysterious and beautiful Xinjiang for a summer report. During the investigation, they encountered incredible things one after another, including thousand-year-old ancient murals, the last tombkeeper in the desert, and huge mountain walls carved with various Buddha statues. All kinds of clues were like invisible hands leading several young people towards the unknown world. What do the ancient Western characters on the stone door foretell? Who carved it? What is the connection between what happened in the underground palace a thousand years ago and a few young people? Can they come back?
