Return to Tibet

Zhong Hao, an ancient book restorer at the Provincial Library, discovered that the pages were spinning in the absence of wind the night he finished repairing a Ming Dynasty manuscript. The rhythm of the paper's rise and fall is like breathing. Following the direction of the book spine, he found the dark green notebook left by his grandfather. There is a line written on the title page: "July 14, 1998. I saw a crack." Grandpa worked in the library for nearly thirty years, and finally disappeared quietly at the end of an abandoned old passage. The notebook contains observation data that lasted for five years - about the pulsation frequency, pressure value and crack width of a certain "pillar". Behind the data is a secret that has been deliberately concealed. On Monday, new colleague Bai Wenqing joined the company. There was an awkward quietness about her, and her way of turning pages was exactly the same as her grandfather's. Deep underground in the library, an ancient passage dug hundreds of years ago is being reactivated by unknown people. At the end of the passage, something pulsed rhythmically—the same rhythm as the book's breathing. Zhong Hao began to follow the clues left by his grandfather. He thought he was tracing a dusty past, but he didn't know that he was walking into a dilemma that had lasted for hundreds of years. Some secrets are locked underground not to hide them, but to wait for someone to open them.
