At the end of the morning's lesson, Montoya and Claire were the first to leave, and Owen thanked him for staying here and serving as an assistant to the old mage.

Unexpectedly, the old mage refused: "You don't have to stay here, go back and practice magic." Leo, this kid is good, I'm very easy to call. ”

Owen had no choice but to say goodbye and leave, and before he went out, he glared at Leo with resentment.

Near noon, the old mage was not in a hurry to start the crystal seed, and he couldn't bear the hard work of more than ten consecutive days, so he let Leo move freely, and he went back to the room for a lunch break.

Such a rare opportunity, how could Leo miss it, he immediately walked around the real room. I don't dare to steal anything, but with the permission of the old mage, I can find a few books to read, and there is absolutely no problem.

First, he checked all kinds of magic materials and magic tools, and finally Leo stopped in front of a bookshelf, picked up a copy of "Introduction to the Mathematical Theory of Magic", and flipped through it.

However, this book, which seems to be quite high-grade in name, does not have much content that excites him, basically some mathematics knowledge from elementary and middle schools in his previous life, which should be one of the textbooks taught by the old master.

After reading a few pages, he found that although there was no change in the principles of mathematics, the level of teaching in this world was not so developed, and the book was a bit messy in terms of exposition and examples, and it was no wonder that the old master gave such a bad lecture.

"If I compile textbooks from elementary school to high school here, I don't know if I can sell them at a good price. But I don't seem to remember much of those contents, alas, I really learned a little and forgot a little. ”

Thinking of this, Leo simply asked the professor to make a copy of the book, so that he could read it when he had time, and it should be reviewed.

As soon as he finished copying "Introduction to the Theory of Magical Mathematics", the door of the real yàn room was pushed open, and Leo hurriedly turned back, but he didn't expect it to be Montoya, who had gone and returned.

Bowing down, he greeted softly, "Good afternoon, Young Master Montoya." ”

Montoya didn't have much to say when she arrived, waved her hand disappreciatively, and asked, "Where is the teacher?"

"The master has gone for a lunch break. Leo replied in the lowest voice, he didn't dare to disturb the old mage.

"Oh, forget it. Montoya was a little disappointed, and noticed that Leo was reading, and he was curious, "What book are you reading?"

Listening to the other party's question, Leo raised the book in his hand and let Montoya see the cover, "It's "Introduction to the Theory of Magical Mathematics". ”

"Can you read it?" asked Montoya, with some confusion.

Leo didn't know how to answer for a while, but he couldn't lie nonsense, so he said, "I probably understand." ”

Montoya was immediately surprised, "Have you studied math before?"

Leo pondered his words for a moment, and replied, "Well, my father was a businessman, and I learned a little from him. ”

"Oh, oh, what have you learned?" Montoya's eyes almost lit up, full of anticipation.

Leo felt that something seemed wrong, and hurriedly whispered: "Some fur will just count." ”

"Fur, that's better than nothing. Montoya took a piece of paper from his pocket and handed it to Leo, "Look at this problem, can you solve it?"

Leo took it and couldn't help but be stunned, isn't this just an application problem?

"Ibisian has a Khadgar meadow that grows at a uniform rate every week. This meadow can feed 27 Kodo beasts for 6 weeks, or 23 Kodo beasts for 9 weeks. So, how many weeks can this meadow feed 21 Kodods?"

After thinking about it for a while, I can use this to establish some intersections with Montoya, and there should be no adverse reactions. Leo smiled, "Young Master Montoya, can you give me a pen?"

Montoya said with some surprise and some disbelief: "Do you have a way to calculate it?"

"I can give it a try. Leo's humble response, in fact, has a way to solve the problem in his heart.

Montoya hurriedly took out a pencil from his pocket, "Then tell me quickly, it's okay, just write it on it." ”

Seeing Montoya's anxious roar, Leo pointed to the old mage's room, "The master is resting inside, or let's go out." ”

"Okay!" Montoya almost trotted out of the room, and Leo shook his head.

Outside, Leo explained to Montoya while calculating.

I have to admit that Montoya really has no talent in mathematics, and Leo has a lot of effort, and he doesn't understand how to solve the problem.

"The original grass ...... The new grass ......" Montoya muttered in confusion, and suddenly exclaimed, "Isn't this a multivariate equation?

"Is it awesome to know how to do multiple equations?" Leo felt a little amused, but he could, "My father taught me some." ”

Montoya didn't continue to ask, straightened out his thoughts, and said hatefully: "Damn Owen, he actually bluffed me with the multivariate equation problem that he didn't learn!"

As soon as he heard that the boy's tone was wrong, Leo immediately remembered the experience of going to the real yàn room at the beginning, and said tentatively, "I found that you and Miss Claire don't seem to like Master Owen very much. ”

"That's right, that guy, relying on his own little cleverness, went to our Joseph's house to go wild, and sooner or later I will give him some color to see!" Montoya's face was full of unhappiness, and continued: "Leo, you tell me a good talk about it again, after you calculate it, I will go to Owen, hum, a hundred gold coins, this will definitely make him hurt for a long time!"

Leo could have guessed without asking that it must have been two teenagers who had made a bet with this math problem.

Owen's attitude towards himself is not friendly, and even vaguely targeted. Judging from the current situation, this young master Montoya has a pure temperament, and Leo doesn't mind helping him. After sorting out my thoughts, I simply abandoned the equation solving method and explained it in the most simple and easy-to-understand way.

Seeing Montoya nodding in understanding, Leo continued: "The amount of grass in this meadow changes every day, and the key to solving the problem should be to find the constant amount, that is, the amount of grass in the original. This is because the total amount of grass can be divided into two parts: the original grass and the new grass. Although the newly grown grass is changing, it should be noted that it is growing at a uniform rate. Therefore, the amount of new grass in this meadow every day is also constant.

............

After half an hour, Montoya finally learned how to solve the math problem completely.

He recalculated it again and asked, "Sure enough, it's 12 weeks, I just calculated right?"

"Yes, Master Montoya is so smart. Leo praised against his will.

Montoya was still a little self-aware, and waved his hand again and again, "I'm not smart, it's you, you can solve such a difficult problem, how did you come to our house to be a servant?"

There is nothing to hide about this kind of thing, Leo said honestly: "My parents died due to accidents, and I have no source of livelihood, so in order to survive, I have to come here to be a servant." ”

"Oh, that's pathetic. Montoya looked at Leo sympathetically and said, "That's it, since you helped me calculate the problem, the hundred gold coins you won will be rewarded to you." ”

As soon as he heard that the other party really wanted to reward himself, Leo had an idea and said: "Young Master Montoya, the reward is not needed, and I don't need the money now, can you give me some magic crystals?"

"You're not a mage apprentice, what do you want that thing for?" asked Montoya, puzzled.

Leo smiled, "You know, I work in the real yàn room, and the magic array in the storm wolf room needs to be driven by magic crystals, although there are rations in the real yàn room, but some are reserved on my body, it will always be safer." ”

Montoya realized that according to the market price, a hundred gold coins should be able to buy a few lowest-grade magic crystals, and it was not difficult for him to get this thing, so he said, "Okay, then I will use this hundred gold coins to help you exchange them for magic crystals." ”

Without waiting for Leo to thank him, he patted his head again and continued, "Oops, how did I forget this. The real yàn room is not very good, and people often die, so I'll go find someone to talk to you, and transfer you to my full-time servant, so it will be safer. ”

After so many days of hard work, Leo was physically and mentally exhausted, but he didn't want to leave the real room. After all, it is worth taking some risks to give a level 6 mage a hand and what he can see.

Take the Bloodline Essence as an example, Leo already has a basic understanding of the previous steps, this extremely important knowledge, you can't learn it with any money.

Therefore, he politely replied, "Young Master Montoya, thank you for your kindness, but once I change jobs, I am afraid that Master Byron will not continue to allow me to read in the Shiyàn room and here...... I don't want to pass up this opportunity. ”

"That's okay, anyway, the teacher seems to like you a lot, I guess I can't open my mouth, it may not be possible, you pay attention to your own safety. Feeling the seriousness of the other party, Montoya is not easy to force. Then he stopped talking a little and stopped for a while before he said: "Leo, I have not been able to learn math well, and the teacher has very little time, can you teach me when you have time?"

"Of course there is no problem, but I only know a little bit, I don't know how much I can teach you. Leo replied cautiously. In fact, he didn't have the slightest worry in his heart, with his level, teaching high school students may be a little difficult, but teaching elementary and junior high school is quite sure.

Montoya laughed cheerfully, "You just said it well, there must be no problem." Then it's decided, as a reward, if anyone dares to bully you in the future, come to me directly, and I will cover you. ”

Although he is not the son of the count, as a very close nephew, Montoya still has some status in the castle, and it is definitely not a problem to at least pack up a few servants, so he dares to make this kind of guarantee.

"Thank you so much. Leo said respectfully. It seemed that he had already gained Montoya's favor, but he was not prepared to ask about the Plane Meditation Method immediately, it would be too abrupt and likely to backfire.

The reason why Montoya came to the library was just to try his luck and see if he could find the answer to the math problem, but with Leo's explanation and promise, he didn't have the heart to stay here, so he said: "Hey, hey, now I'm going to settle accounts with Owen, do you want to continue reading here?"

"Yes, I'd like to read a little more here for a while. Leo nodded.

"I really envy you, to be able to read books, alas, why can't I. Montoya sighed, and then bounced away, without any sadness.
