Shen Zhiwei, an ancient book restorer at the National Library, was pulled into a mysterious bookstore by a piece of ancestral jade while repairing a letter from the battlefield in 1937.
There are thousands of books and thousands of volumes of obsessive books. Each book is sealed with an unfinished regret - the unsent home letter of a war correspondent, the tampered application form of a rural candidate, the burned playbook of a famous Kunqu opera actress, the lost wedding stitch of an embroiderer...
Holding the pen as a blade, weaving dreams to make up for regrets. Shen Zhiwei uses ancient book restoration skills to rewrite the meaning in the book world, but discovers that the truth about his sister's mysterious disappearance ten years ago is hidden in the deepest part of the bookstore——
In the source book of "The Classic of Mountains and Seas", her sister is waiting for her.
And as she gets closer to the truth, a more cruel choice lies before her: rescue her sister, or protect the destination of thousands of people with obsessions?
"Sister, see you in the next book realm."
