In the afternoon of the next day, Aaron put aside his possession for the time being, and then rode alone in a carriage to Persein's lodgings, which were not far apart, only two small blocks apart, and arrived at their destination in less than five minutes.

The place where Persein lived was twice as large as Aaron's, and Aaron was led by a servant to wait in the hall, drinking tea and looking around at the decorations.

"This Persein seems to be very particular about decoration!" The interior of the hall is richly decorated, and the furnishings are also symmetrical, and it is clear at a glance that it is carefully arranged, and the magnificent appearance of Persein's carriage, it can be seen from these details that he has high requirements for decoration.

In this regard, Aaron is completely different, he personally does not have a lot of interest in these things, he can just see it, and he is not particularly particular, as long as it is not particularly ugly.

After waiting in the hall for a short time, Persein hurried over from the garden, and said with a smile: "I just heard from a servant that you came to visit, I wonder if Brother Aaron needs help this time?"

"Won't it bother Mr. Persein when he comes suddenly?" said Aaron, standing up and nodding slightly.

"Don't bother, don't bother, I'm very idle today, I've just been in the back garden to breathe. However, if you want to visit in the future, you can send someone to inform me in advance, so that I don't happen to be busy, or I have to go out, so you can run for nothing. Persein smiled and shook his head.

"Next time, I'll definitely have someone come over and let me know, this time it's a shame. After a few polite words, Aaron then said the purpose of his visit: "Mr. Persein, I am not here to ask you for any help, but to enrich your knowledge and have some exchanges with you. Of course, if you have the knowledge you need, you might as well exchange it. ”

"I can't see that your thirst for knowledge is quite strong, brother, and I like that. With an admiring look on his face, he gently patted Aaron on the shoulder and said, "Let's go, I'll take you to my library to have a look, it shouldn't disappoint you!"

"Thank you very much!" With that, Aaron walked side by side with Persein, and walked slowly down the stairs to the second floor.

After half a circle on the second floor, the two came to a large door, only to see that Persein cast a simple little spell, and then the door opened automatically.

The space in the room is almost cylindrical, with a circle of bookshelves clinging to the walls, filled with all kinds of books, large and small, new and old, and some even looking very dilapidated.

There are also two triangular ladders in the library that can be pushed, mainly under the shelves, to help the book picker get the books that are taller, which is very convenient.

"There are so many books, it seems that the database can be replenished a lot this time!" Looking at the dazzling array of books around, not to mention two or three thousand, Aaron was overjoyed, feeling that this time would definitely not be in vain.

Since it is a mage's library, the books in it are definitely not useless biographies or the like, they must be materials related to the mage profession, and they all have a certain value for Aaron.

"Brother Aaron, how is it? The books here have taken me most of my life to collect, and they should be of help to you. Looking at Aaron's slightly surprised expression, Persein couldn't help but smile a little proudly.

"It's really amazing!" Aaron nodded with satisfaction, "Can I read all these books?"

"Of course, in fact, these are ordinary materials and notes, and there is no particularly valuable knowledge, you can watch it at will. Persein nodded in agreement. Although there are a lot of books here, those more precious books are hidden in other places by him, and they are not kept here, so Aaron is allowed to consult them at will.

"It seems that the really good books should not be placed here, but these are also not a small gains!" Aaron saw that Persein was so generous that he could actually watch them all, and then he knew very well the reason, the really important materials could not be viewed for free.

"Then thank you, sir!" Aaron expressed his gratitude, and continued, "By the way, I don't know if these books are classified, I have to pick a few books that I am interested in and consult, so many books I don't know where to start." ”

Hearing this, Persein walked over to one of the bookshelves, took a thick hardcover book from the middle, and handed it to Aaron. "This is a general catalogue of books in the library, which records the classification of all the books here and the location of the shelves, so you can pick the right books from it and take them down. ”

"Oh, it's really convenient to have this general catalogue. Aaron took the thick table of contents and lifted the cover to look at it.

Actually, Aaron was going to look at all the books here, but that would definitely attract Persein's attention, and unless he wasn't there, he had to take his time.

After checking the catalog, Aaron picked out a dozen useful books from the shelves, stacked them on the table, and then said to Persein: "Mr. Persein, I'll look at it here for a while, and if you have something to do, just go and get busy." ”

Aaron said this as if he had broken away from Persein, but he said, "Brother Aaron, don't worry, you can take these books back and read them, and then return them to me when you have finished reading them." Didn't you say you were going to exchange knowledge, I have something here that you should be interested in. ”

"Oh, what is it?" Aaron's eyes lit up when he heard this, his main purpose here was to exchange those precious materials, anyway, the large amount of spell knowledge he had obtained from the evil dryad was completely enough to exchange capital.

"I'll show you a little bit more intuitive than I said. Persein said lightly.

With that, Persein ordered one of his servants to bring a crosssword.

Seeing that the servant brought a cross sword, Aaron was very puzzled, he couldn't see what he wanted to do, and after analyzing the chip, the cross sword was very ordinary and nothing special.

"What I'm going to demonstrate now is a method of enchantment. As soon as he finished speaking, Persein's eyes were fixed on the cross sword in his hand.

"Chip, analyze what the hell he's doing!" Aaron instructed Chip, then closely watching Persein's every move.

"Found the Elemental Stand, there are a large number of elements gathered on the Cross Sword, the reason is unknown. After a few seconds, the chip fed back information, and Aaron learned about it and immediately focused on the sword.
