The book in his hands was not opening, it was not bulging either. No matter how much strength he applied, it was just not opening.
Ryan had similar experiences with the VIP doors. They were not something you could open with pure strength; but with Ryan's skill Vision, it would tell him the passcode- or at least tell him how to open the door.
Ryan related that same logic to this book. If he can't open the book with pure strength then maybe he can open it with the help of his System?
"Vision"
< A vampire diary: Diaries specially made for strong vampires who have lived for more than fifty years. These diaries are made from King-tier beasts. >
< You can not open these diaries with pure strength. You need the owner's blood to open up these diaries. These are very important for vampires. >
Ryan was impressed by his System but more than that, he was stunned by what he was holding in his hands.
