Deep in the corner of the National Museum of Culture and History, there is a fringe department called the "Miscellaneous Information Collection Office." There are only three employees here: a taciturn deputy director, a file administrator who never smiles, and a history master who has just taken the public examination.
Chen Yibai thought that his job in this life was to drink tea, read newspapers and sort out folklore. It wasn't until his third day on the job that he was taken into the secret door of the archives room. From then on, he knew two things: first, the real name of this organization is "Guanshi Division", and its duty is to send people to travel through time and space and visit historical sites to observe the truth of unsolved mysteries; second, the Guanshi Division has only one iron rule - only see, don't tell, and never interfere.
The first mission: Mawei Station, the 14th day of June in the 15th year of Tianbao, the death of Concubine Yang.
Chen Yibai stood under the moonlight a thousand years ago, watching history happening in front of his eyes, but could do nothing. And there seems to be an unspeakable secret hidden between the taciturn boss Lu Guan and Ma Weiyi. The archivist Su Mu, who never smiles, has the aura of the prosperous Tang Dynasty and an ancient silver hairpin of unknown origin.
About history, they say nothing.
But some truths don't need to be spoken, they just need to be seen.
