Under the neon lights of the city, there is an ancient existence called the "Ink Beast" lurking, which makes a living by devouring human civilization. 17-Year-old Lu Li suddenly discovered that he could understand the long-lost writing in the world - the language of the ink beast.
In a disaster disguised as a gas explosion, a burning parchment chooses him and draws him into a secret war that lasts for thousands of years. In this world, books are weapons, knowledge is a curse, and words themselves are double-edged swords.
The "Library" and the "Book Burners", two opposing organizations, both extended an olive branch to him. The former protects knowledge, the latter destroys danger. When Lu Li discovers that he may be the most dangerous "living library" in history, he must choose: become a guardian of knowledge, or become a book-burning monster?
The boundaries between civilization and barbarism begin to blur. Every turn of the page may awaken a sleeping demon or ignite a spark of hope.
