Xu Mu carried two crystal cards and searched for them on the nearby bookshelf.

At first, Xu Mu thought that the bookshelf would be based on seven series of magic, and then divided into several bookshelves, and then found that it was not.

The seven types of magic are not only destroying one, such as the alchemy of earth magic, the levitation of wind magic, and the shadow cloud of dark magic... It's all magic that has other important roles.

These spells are difficult to learn, and if you don't understand them enough, even if you have enough magic and know the spells, you won't have a high success rate in using them.

Fortunately, Xu Mu originally regarded magic as a discipline, and he didn't find it difficult to understand.

He went to a bookshelf and pulled out a book.

The ebony-framed book is very heavy, and there are no words outside the texture of the engraved patterns on it, Xu Muzheng was strange, and suddenly magic appeared on the surface of the book.

The magic emanates from the inside of the book, and then the magic slowly solidifies into words on the cover of the book.

"The Theory of the Evolution of the Light Element?What is the historical process and significance of the light element from its initial birth to the present day?Watch 40 magic points, and rent 100 magic points a day?"

Xu Mu couldn't help but raise his head tactically, this writing thing was really too disciplined, but I have to say that he was actually very interested.

After all, he had never been exposed to these things, and Xu Mu had studied things from other disciplines, which could be described as smelly and long, which was very unpleasant.

But now, although these magical theories seem to be messy and long, the yearning for magic in his heart does not make him disgusted in his heart.

"It's a pity that I'm too early to learn these theoretical knowledge, and I don't even know the first level of light magic, so forget it. Xu Mu shook his head with a smile and stuffed the books back onto the shelves.

Then Xu Mu began to shuttle back and forth between the various bookshelves, mainly trying to find some books that suited him.

Of course, he was mainly looking for books on fire magic.

It didn't take long for Xu Mu to have two fiery red cover books in his hands, one was "Practical Spells for Fire Magic" and the other was "Analysis of Fire Magic Spells".

Although the fire-based magic Ailu has taught Xu Mu a lot, this thick fire-type spell book is obviously more complete and complete, anyway, it should be supplemented and reviewed, it doesn't matter.

However, it stands to reason that the first book is more practical, and usually requires more magic points than theoretical books.

But it's not.

For example, the second book in Xu Mu's hand about the analysis of fire-based magic spells costs 80 magic points to watch, and 200 magic points to rent a day!, while the first book only needs 20 magic points to watch, and only 60 magic points to rent a day.

The difference in the number of magic points required for these two books was too big, and Xu Mu was a little stunned.

But because of this, Xu Mu was even more interested in this second book, what kind of theoretical knowledge could make it cost so many magic points to watch?

However, the cost of this book is too large, which makes Xu Mu, who is not rich in magic points, feel a little cowardly in his heart.

After thinking about it for a while, Xu Mu put the second book back on the shelf, although he was very interested, but the cost was too great, and he was a little ruthless.

Xu Mu was holding the "Practical Spell of Fire Magic", he tried to open the book with the fiery red cover, but found that he couldn't break it no matter how hard he tried, it seemed that there were other ways to open it, but Xu Mu didn't understand.

Just as Xu Mu was scratching his head and thinking about how to open it, a familiar gentle and sweet voice sounded next to him.

"You have to take out the crystal card, and then enter the magic into the crystal card, and then pass the points of the crystal card into the book, and then if you want to watch it for a day, enter 20 magic points. ”

Xu Mu turned his head and looked, but he didn't expect it to be Betina.

Bettina's beautiful black long drape spread out, her blue eyes made Xu Mu a little distracted, and her delicate face had a faint smile, and the quiet girl could be described as beautiful and delicious.

Xu Mu coughed: "Betina, why are you here?"

"What? Is the Magic Academy library still owned by you? Why can't I come? ”

Xu Mu realized that he had said something stupid, and quickly changed his words: "No, I mean... There are a few bookshelves around here that are dedicated to fire-based magic, and I think you only seem to be adapted to the wind, thunder, and earth, right?"

"You even know this?" Bettina turned around and picked up the second book that Xu Mu had just put back, she looked at the "Fire Magic Spell Analysis" in her hand, and didn't know what she was thinking.

"The Queen has told me something about you... However, the three systems of magic that the Bei Ti family have awakened for generations, it seems that they are all these three systems, and I don't think it is particularly difficult to know these. ”

"But the Queen has never told me anything about you, and she has never told me anything about your identity. ”

"Huh?" Xu Mu was also a little strange, "Didn't the queen's letter say anything about me?"

"I said a little, but I didn't go into details. ”

Xu Mu couldn't help but get nervous when he heard this, could he be too self-righteous? Thinking that Bettina and Xenia were childhood friends, coupled with Hea's words, he subconsciously thought that Bettina and Xenia still had a good relationship.

Isn't their relationship as good as she thought it would be? That's why Xenia didn't tell Bettina about my identity in the letter?

Did I do something wrong and be passionate?

But if Bettina and Xenia have a bad relationship, what should Xenia do with me to have a good relationship with her?

The more Xu Mu thought about it, the more strange it became, and the more he thought about it, the more scared he became, if he really thought he had made a mistake, which would affect Xenia's follow-up plan, then it would not be an exaggeration for him to lose his head...

Xu Mu soothed the tension in his heart, changed the topic, looked at the book in Betina's hand and said, "This book is about fire magic, it's useless to you." ”

"It's okay, it's better to know more than less, what do you think?" Bettina smiled lightly, "But Xu Mu, you don't think I'm following you, right?"

Xu Mu was stunned: "How could it be..."

"You just looked at me strangely. Bettina shook her head, "It's rare for a knight to appear in the library, you don't know how eye-catching you are in the library? I remember that the new cadets of the knight alternate only gave 100 magic points each, and you dared to come to the library to use it for only a few days, are you too anxious? ”

"It's okay, Ai Lu's 100 points are used for me, and 200 magic points are not much, and they are not as good as your noble students, but for me they are about the same. Xu Mu narrowed his eyes and looked at the book in his hand that had not yet been opened: "Let's experience it first." ”

Xu Mu took out the crystal card from his uniform, and urged the magic power in the magic seal to be transported into the crystal card, and the crystal card trembled for a while, and the number 100 was displayed on it.

He then pressed the crystal card on the cover of the book, and input the energy of the crystal card into the book.

The number 100 on the crystal card gradually decreases until it becomes 80.

Xu Mu put the crystal card back into his uniform, this time he opened the book again, only to see that he opened it with a slight lift, the corners of his mouth couldn't help but pick slightly, he was very happy, and said to Betina: "Thank you." ”

Bettina didn't speak, and was silent for a while: "You seem to have a good relationship with Ailu, and she is willing to use her 100 magic points for you." ”

"There is no distinction between her and me. Xu Mu couldn't help but laugh when he talked about Ai Lu, "Anyway, thank you for teaching me how to read in the library." ”

Bettina saw Xu Mu's happy smile, her brows couldn't help frowning slightly, I don't know why, she felt a kind of loneliness in her heart.

I never had it, but I felt like I had lost it.

Xu Mu was about to find a place to sit down in the library with the book, when suddenly Bettina grabbed him again, which seemed a little intimate in the eyes of others.

Bettina waved the "Analysis of Fire Magic Spells" in her hand and asked Xu Mu: "You actually want to read this book too, why don't you read it?"

Xu Mu nodded: "Although I really want to see it, it's too expensive, so let's talk about it later." ”

"I can pay you magic points for reading this book, but it's a deal. ”

When Xu Mu heard that he could read this book, he became interested in the transaction in Betina's mouth: "Oh?

"I'll pay you for reading points, and you'll have to answer me a few questions!"

Xu Mu blinked and looked Bettina up and down.

Bettina's face was a little red when Xu Mu's unscrupulous gaze was seen.

"A few questions?" Xu Mu asked.

"Three. ”

"Let me state first, if I am embarrassed by your three questions, I can choose not to answer them, but you still have to pay me magic points for this book to read. ”

Bettina was incredulous, it was the first time she had seen someone make such a rogue request in front of her. In Xu Mu's words, you can ask three questions, but he can not answer, and he still has to read the book, and the points Bettina still have to pay, this Xu Mu is too shameless!

Bettina gritted her teeth: "No problem!"

"Yo, that's it, you can help me undo the limitations of this book first. Xu Mu had the face of a villain.

Seeing this, Bettina was not angry and took out the crystal card from her body, and when her magic power was transmitted into the crystal card, the four-digit number displayed on it frightened Xu Mu.

Rich woman!

Bettina untied the restrictions of the book and stuffed it into Xu Mu's hand: "Okay, can I ask questions?"

Xu Mu was holding two books in his hands, very happy, and kept looking at Bettina slyly, not knowing what he was thinking: "Don't be in a hurry, let's find a place to sit down first." ”

After the two of them found a place to sit down in the library, Xu Mu saw that there was no one around, so he asked with a smile: "Miss Betina, you ask~ But I declare again, if I feel that the question is difficult or I don't know, I can choose not to answer." ”

"I know. Bettina took a deep breath, hesitated for a long time, and asked slowly, "Did Her Majesty have any other orders when you asked you to come to me?"

Xu Mu also thought deeply, he had casually mentioned these things to Bettina yesterday, and now he knew that it didn't seem to have anything to do with her again: "The Queen, he asked me to send a letter to you, so that I can be friendly with you, saying that if my relationship with you becomes friendly, it will be good for Her Majesty the Queen and for me." ”

Bettina hurriedly asked, "Then Her Majesty said that this friendship means that we have become friends... Or?"
