Early the next morning, Ryan rushed to the library alone. After handing Professor Dumbledore's signed note to Mrs. Pince, he was surprised to learn that he couldn't take the books out.

"You can't take it out, you can only see it from the designated location. Why is that?" Ryan asked, puzzled. "I've borrowed books from the forbidden area before, but I don't have so many rules. ”

"Because Professor Dumbledore's permission to read books is beyond the scope of the student, some of these books are a source of danger in their own right, and some of them have defects of one kind or another, such as the fact that the carrier of the book has become very fragile for too long. In this case, it can only be read in a designated place to ensure safety, and safety here refers not only to the book, but also to the person reading the book. ”

After speaking, Mrs. Pince looked Ryan up and down, "Since Professor Dumbledore has allowed you to enter the storage place of the books, then he should believe that you are qualified enough to look at the precious books stored inside. But I still need to warn you, if you destroy any of the books inside, I'll kick you out immediately. Even if Professor Dumbledore came. ”

"Alright, come with me. After warning and making sure that Ryan was listening, Mrs. Pince led Ryan in the direction of the forbidden book section. Surprisingly, they didn't stop at the shelves in the forbidden section. Instead, he walked down the hallway in the bookshelf to the depths of the forbidden section until he stopped in front of a wall.

"This is?" "This is the real place where the important books are stored, and you wouldn't think that there would be any danger or important books in the so-called forbidden book area where the younger students can sneak in at night." ”

Ryan finally knew why Harry was able to enter the forbidden book zone when he was in his first year, because it wasn't a particularly important place at all. This also explains why Hogwarts, a thousand-year-old school, would be so low-alert in places where important books are placed in the wizarding world, when knowledge is so important.

On this wall is a realistic relief of a baboon holding a crescent moon, which in traditional occultism is a symbol of Thoth, the ancient Egyptian god of wisdom. And I don't know if it's an illusion, Ryan felt that the baboon's fur was slightly bent, and the area above his head seemed a little more refreshing.

Ryan suddenly had a strange thought, and he began to worry a little about his hairline. Mrs. Pince, however, did not notice that Ryan was thinking nonsense. She placed the note on the baboon's empty hand, and as soon as the note was placed on her hand, the relief moved.

The baboon held up the note in his hand and pointed it to the moon in his other hand. At this time, Ryan found out that the moon was carved separately from a piece of moonstone and placed on it.

The moonstone carved moon suddenly emitted a silver moonlight, which could be seen clearly even in daytime. In the moonlight, Professor Dumbledore's signature on the parchment also glowed with golden light and silver moonlight.

After the examination, the baboon was back in its original form. Mrs. Pince took the note, handed it to Ryan, and then grabbed a branch from the relief and pulled it hard.

The branch made of stone was pulled like an eraser. When Mrs. Pince let go, the branches returned to their original state. Then there was a click, and a wall on the side of the relief began to move upwards. Finally, a hole the size of a normal door was revealed.

"Okay, follow me and don't touch anything. Mrs. Pince gave a note and walked straight to the gaping hole in the wall, while Ryan followed closely.

It is a very tall room, the main body is a gray, very rough stone, and it looks unremarkable. But Ryan immediately recognized that it was a very good magic stone, which could withstand the attacks of magic, and it was extremely expensive outside. Listen to Fred, in the wizarding world, only the top families can build their own treasure rooms out of various materials. And here, the whole house is such a large space, and at a glance, it is all made of this material.

Entering through that small doorway, Ryan, with his feet on the rough stone floor, had the feeling that he had entered the land of giants by himself. A large number of one- and two-story bookshelves stand there like hills, and there are beautifully crafted bronze escalators and platforms next to them.

"Herbs, magical creatures, enchantments, history—" A variety of books are arranged in different areas according to their categories. There were not only paper books on the shelves, but also on wooden chips, papyrus rolls, and even large stone slabs carved with various characters at the bottom of several bookshelves.

"What a grandiose thing!" Ryan whispered in exclamation, he had never known there was such a place in Hogwarts.

"This has been around since the school was founded. There was a hint of excitement and pride in Mrs. Pince's voice. "The Big Four kept their books and materials here, and for the next millennium, Hogwarts would receive very important or very dangerous materials that the school had collected that were not suitable for the outside, and only open them to students or professors who had been approved by the Headmaster. And anyone who enters this house will have a magical contract with Hogwarts itself, and cannot divulge anything inside to anyone else. ”

Ryan nodded, which would explain why he hadn't heard of this before.

"Alright, put your hands on it. You need to do a magic certification here, and if you feel that the magic in your body is stimulated, don't resist. The two men were now in the middle of the house. In the center of the library is an open space with a stone platform carved out of white marble.

After placing his hand on the top of the stone platform, which was inlaid with a whole sunstone slab larger than the palm of his hand, Ryan felt as if something had swept through his palm, and he felt like he was numb. And this kind of thing also carries magic when it is scanned, so that the magic in Ryan's body reacts like a reflex.

"Maybe magic and science will end up in the same place. Ryan thought, because this stone platform reminded him of the kind of palmprint recognition system he saw in science fiction movies.

"You can put your hand down, your mana fluctuations have been recorded, and the next time you come over, just put your hand in the hand of that baboon relief and you will be able to open the door. Also, your license is limited to alchemy. Therefore, you can only operate in these areas in the future, and if you move in other areas, there will be a magic barrier to block you, and if you force your way through, it will induce a warning. At the same time, no one can spend more than six hours a day in this house, after which the magic inside will be ejected. Finally, I wish you the knowledge you want in it. With that, Mrs. Pince simply departed neatly. Leave Ryan alone here.

"It's time to get started. Ryan muttered to himself and walked towards the alchemy area, even if the alchemy he had mastered before was very profound, but the rules would vary from world to world.

Therefore, if you want to exert full power in this world, then learning the alchemy of this world is a good way. At least it's much better than groping around alone through various attempts.
