What you touch with your fingertips is not ink stains, but the blood flowing through history.
Mu Mu, a top restorer of ancient books, was caught up in the roar of Suzhou looms in the Ming Dynasty when she touched the remaining pages of "Tiangong Kaiwu".
She was shocked to realize that the ancient books in the world are a living door to the past history.
A mysterious force is frantically tampering with the pages of the book.
Farming, a vital skill for the people, was deleted, and thousands of acres of fertile farmland dried up overnight.
The tea book and tea ceremony were torn apart, and thousands of years of tea culture disappeared from everyone's memory.
She traveled between the lines in order to restore intangible cultural heritage and correct history. However, while tracing the truth behind her father's disappearance, she fell into a thousand-year struggle between the secret keeper and the tamperer.
Until a bloody line of annotations suddenly appeared at the footer of "Xu Xiake's Travels": "Those who travel through time will stop."
Only then did Mu Mu realize that what she risked her life to protect was not only the civilization in the pile of old papers, but also the last line of defense for the survival of the real world.
