Therefore, the paper restorer Huai Shu has a pair of ears that can hear the breathing of the pages.
Her new mission is an unknown ancient book from the Ming Dynasty. This book is extremely strange: it is immortal and immortal, but it is completely cold. No matter what method you use, you cannot open even a corner of it. Everyone who has touched this book begins to dream of the same scene - the back of a woman standing in front of a door that is about to be knocked open, over and over again.
With the master's permission, Huaishu used the blood on his fingertips as a guide to forcefully enter the "paper tomb". She transformed into the daughter of a criminal whose house was about to be confiscated in the book, but she discovered that there was a paradox hidden in the book: everyone said that the secret behind the door would destroy her family, but the book spirit itself was trying its best to prevent anyone from opening that door.
What is behind the door? Is it the shocking injustice that the wordless book is about to expose, or is it the most private love of girlhood that the book spirit has spent three hundred years guarding and does not want to be seen?
As the restoration progressed, Huaishu realized to her surprise that the obsession of this book was not directed to the past, but to the present - the person who had been waiting for three hundred years by the book spirit was herself.
