The male protagonist Shen Mo, who is also a librarian, accidentally obtained the "archaeological/treasure hunting system" while sorting out old books. Not only can he see the age and authenticity of antiques, but he can also hear the "original echo" of history by touching the objects.
The story begins when he accidentally identifies a piece of "Ming Dynasty Heaven-Sacrifice Jade" that was used as an ashtray. He discovers that the jade contains an unrecorded truth about the "Renyin Palace Incident" in the Ming Dynasty - that the palace maid strangled Emperor Jiajing was not an accident, but to seal some kind of horrific inheritance.
Silent's discovery attracted the attention of Su Qingci, a female curator in the capital, and the two were forced to bind. As the investigation deepened, Shen Mo discovered that the underground of the library he managed actually contained the ruins of the Ming Dynasty's secret prison.
In the tight rhythm of just 60 chapters, Shen Mo uses the system to pick up leaks in Panjiayuan, survive in ancient tombs, and piece together seemingly unrelated cultural relics (a broken comb, a fake painting, a copper coin) into clues, and finally finds the missing pieces of the legendary "Jade Seal of the Country", and reveals the betrayal and conspiracy of a tomb-keeper family that has lasted for six hundred years.
