Legend has it that in the depths of the desert near a small town in the northwest, there is a group of ancient tombs that have disappeared for a thousand years. The tombs contain not only rare treasures, but also the legendary treasure "Soul-Calming Mirror". This "Soul-Calming Mirror" is the only key to open the "Soul-Calming Coffin", but it is extremely dangerous and people always die in vain because of it. In order to find clues about the tombs, Wang Qingnian, a tomb raider, and his partner Li Erdan disguised themselves as oil workers and mixed into a group of college students' inspection team. A gust of wind blew, and while avoiding the storm, everyone fell into a dangerous underground palace and was forced to start a thrilling journey of breaking the mechanism and breaking into the tomb.
