wooo...what an antique book! 无字天书...will only appear in the world of martial art^^ but I found it in reality! haha...looks cool huh! when I open the book, it's empty! all pages NO word, NO graffiti, thought it really was a 'book without words' which have to apply special tactic to read the book with words. In fact, it's just a notebook..haha....
