In the Last Days, I Rely on Books to Save the World

Lin Yuan was originally a librarian at a remote shelter. During an attack by looters, in order to protect the collection of ancient books, he accidentally activated an ancient armor under the Bookstore that had been dusty for hundreds of years - "Shou Zang". The driving core of this armor was actually his own belief in knowledge. In order to pursue the "Echo Formula" that can convert the "Silent Field" into new energy and purify the world from its roots, Lin Yuan drove an armor to protect a young scientist who had mastered the key fragments of the formula, and stepped into the wasteland where all forces competed. What he faced was not only mutated giant beasts and powerful enemies, but also the ultimate torture of the existence of human civilization.
