In the winter of the 26th year of the Republic of China, the Battle of Songhu came to an end, and Shanghai became an isolated island.
Shen Yanqing, a professor at Jinan University, is a genius in edition catalogues. He can judge the authenticity of ancient books based on half a page of scraps. He resigned from his teaching position and stayed on an isolated island, just to pick up Chinese classics scattered in the market amid gunfire.
Osamu Sato, the head of the Japanese Army Documentation Section, has a doctorate in Sinology, but in the name of "cultural co-prosperity", he came with the "East China Document Collection Outline" and vowed to systematically search for the thousand-year cultural context of Jiangnan.
Chen's library was burned to the ground, and the old man died in the fire holding his books. Shen Yanqing finally understood - giving in can't bring peace, and hiding can't protect one's roots.
He took the Qingtian stone seals to "guard the collection" and formed a secret society with second-hand bookseller Wei Erye, Commercial Press executive Meng Jingzhi and others. Using his expertise in identifying forgeries, his connections in the world, and the cover of the business community, he launched a silent cultural secret war with the Japanese army in the cracks of the concession.
He cheated the counterfeiting bureau, intercepted the auction house, hid thousands of scrolls in the cellar, and transported the only copies out of the city.
One person keeps the book, and everyone keeps the treasure. As long as the book remains, the cultural context will not be broken.
