"There are only 346,120 books," answered Charlotte.
"And you have read all of them?"
"Of course not. Even two hundred years is hard to actually read all these books by myself, let alone if I have to add more knowledge about the recent understanding. I have only read around half of them."
"Almost a thousand books a year is impressive, you know." Nathan shook his head helplessly. "Then, do you know the content of all those books?"
"What do you think? I don't have a photographic memory. Even if I can record all this book, there will be some losses once I'm integrated back into my main body." She sighed. "However, I understand the general knowledge of those books. If I don't know something, I will simply open those books again."
"That's amazing." Nathan looked down, falling into deep thought. "What kind of books do you have here?"
"All kinds of things, from basic knowledge to advanced stuff like engineering or unique techniques."
