The Book Is Not a Book

When he was 10 years old, Yang Letian came across a mysterious white-haired old man while herding cattle. The old man handed him an old book without words and said with a smile: "Little boy, this book can contain everything in the world." Yang Letian took it half-heartedly, and that night small golden letters appeared in the book: A drop of blood will reveal the master. He bit his finger and the blood dripped. For a moment, his whole body was sucked into the world of the book—— In front of us are fairy mountains, spiritual springs, vast tracts of spiritual fields, and even a library that contains secret books of martial arts that have been lost for thousands of years... Yang Letian's heart beat like a drum. What kind of miraculous path will this wordless book take him to?
