This [Library of Heaven's Path] is a fantasy novel with the MC being a modern bookworm or librarian named Zhang Xuan that is transported into different world and becomes an honorable teacher. A mysterious library appears in his mind. As long as it is something he has seen, regardless of whether it is a human or an object, a book on its weakness would be automatically compiled. Thus, he became formidable. Currently at chapter 5, but it already is very hilarious to read. What are your review?
