When civilization is formatted with one click, guarding the last line of ink becomes mankind's greatest war.
An unknown disaster called "data annihilation" has completely pushed human civilization back to the primitive era. The hard drive turned into nothingness, the network was permanently disconnected, and even the memory of modern technology in human brains disappeared with the wind. The world has fallen into cognitive darkness, and chaos and despair have become the main themes.
Among these ruins, a century-old National Library has become the last beacon. Lin Shoumo, a paper book restorer who was once forgotten by the times, has now become the most important guardian of human civilization. He and a small team composed of retired soldiers, erudite professors and genius girls stick to this isolated island of knowledge.
They hold the blueprint to rekindle civilization, but they also possess forbidden knowledge that could destroy the new world. Outside, powerful warlords are eyeing this "treasury of truth"; inside, the authority of knowledge collides fiercely with the belief in sharing. Should they monopolize knowledge and become the gods of the new era? Or spread it out, risking another disaster?
When the last page of the ancient book is opened, mankind will usher in a future written by their own hands - will they repeat the mistakes of the past, or will they move towards a new life?
