Before the renovation of the new home was over, Lin was about to usher in his first class.

The reason why it is so fast is because the first batch of students has already been decided. All the magicians in the academy signed up, including the Grand Magicians Kabanbay and his wife, as well as certain well-informed people. The latter may be a student in the academy themselves, or a particular person who is interested in someone's movements. Some of these people are sincere in seeking advice, and of course there are also those who are ready to provoke.

Someone is not afraid of this. Behind him stood Liu Hui, Zhao Shuang, Zu Chongzhi, Gauss, Newton, Archimedes and other Chinese and foreign bulls, if they were still tested by the aborigines of this mathematical desert, then they could only sigh that they were not good at learning and embarrassed.

Because it was the first time to teach, and I was busy with my new home, I didn't have time to visit the dock at the college to familiarize myself with the environment. Therefore, for Lin's first lecture, the great magician Kabanbai cautiously sent a carriage to greet him.

For such a battle, someone has to admire, he really deserves to be a master-level figure, and the pomp is really complete. It's different from the kind of wild mage who rolls in the mud and has no meal. Thinking of myself when I first crossed over, squatting in a dung pit waiting for the life of uncivilized goblins, it was like another world.

Because the new home is not far from the college, I gritted my teeth and endured the uncomfortable feeling of this carriage for the second ride. The last time I sat down, I went all the way to the house of the great magician Kaban, not to mention that Fen was complaining, and even he regretted it. On the return trip, he refused with various excuses, and ran away with flashing techniques when he got out of the gate.

This time I sat again, it was really because I was not familiar with the place, and then things had to be arranged by the great magician Kabanbai, so I directly asked the other party to arrange a full set. Save yourself from making demands everywhere, and in turn hope that the other party will cooperate, making you feel as if you are very uncooperative. Leaving a bad impression is not good for the future.

As soon as you enter the gate, which is guarded by the Iron Puppet, the style of Kabambai Academy is strongly noticed. Similar to the oldest universities in Europe on Earth, it feels like a palace complex. Marble columns and cornices carved with various decorations are used as the main tone, giving people a heavy and solemn sense of sacredness.

Considering the current state of the Lost World, nature is still stronger than civilization. Therefore, people who are fascinated by the land will not be obsessed with the construction of parks and landscaping like the earth. However, there are a lot of green landscaping in the college, and it is carefully organized and planned, with a strong European style. It's as if the magicians are preaching the words that I will conquer nature.

There is a considerable distance between the buildings, as if the king cannot be compared to others, and each building stands alone. But according to the driver, this is actually to avoid students or magicians studying inside, and when they are conducting magical experiments and unfortunately lose control, the magic that gets out of control will not spread to other places.

It was also under the introduction of the driver waiter who felt that he should be very powerful, and Lin also had some ideas about the vast academy. Of course, the action of secretly opening the map is indispensable.

At the same time, I understand why Kabam chose to build an academy on the outskirts of Estali. Because in the old town, that is, near the inn where I used to live, it is impossible to build such a large area of open space.

The carriage travels in front of a smaller, less inconspicuous building than the others. According to the waiter, each building in the academy is named after the courses taught in it. In addition to the lectures, the magicians who are the teachers are also provided with a rest room, and the interior is freely arranged. There are similar courses in one place, which is also convenient for teachers to communicate with each other.

When someone heard this, they couldn't help but complain in their hearts, this department was not only established, but also the territory, which really looked more and more like a university.

The place where the driver brought Lin here is one of the few vacant buildings in the academy, temporarily allocated to 'mathematics'. If there is a need for a larger place in the future, it will naturally move to a larger building. As for the lines that were not spoken, it is estimated that if no one reads them in the future, then get out of the academy.

In short, the system of the academy is not completely clear, and many things will change. And the small building in front of me in Kabambai College is the starting point of Mathematics in the Lost Land.

This 'small' building is small, but it is exaggerated compared to the houses where ordinary people live,—— there are three classrooms in total, and there are two classrooms on the first floor on the right-hand side after entering through the main entrance; On the second floor, there is a rest room for teaching magicians, which is divided into four rooms that can be adjusted at any time.

On the left-hand side, there is only one large lecture theatre. The design, of course, came from the Southwest Peninsula, the original defunct academy — I heard that someone took it over, but Lin Ke didn't care,—someone's handiwork.

Generally speaking, only buildings that provide enlightenment education have this kind of classroom, because they can accommodate a large number of students at a time. But today is more special, there are a lot of magicians and non-magicians who apply to audit, and there are not so many people sitting in ordinary classrooms, so I found this building with lecture halls.

The system of auditing is to choose to only take one class, which is different from those who pay more fees and are scheduled to study for a long time. To put it simply, these people may become customers as soon as they hear it, or they may turn around and leave.

Entering the lecture hall, there was no applause, no flowers, and of course no music. Someone is greeted with a pair of eagle-eyed sharp gazes, as if they are about to pierce the person. As for the number of people, maybe the small classrooms can't fit in, but they are not so many that the lecture halls are full.

Lin was not hypocritical, he went directly to the podium and did not introduce himself. Because today's protagonist should not be himself.

As soon as he spoke, Lin asked everyone present: "Why do you want to learn mathematics?" ”

It seems that this question is a question in the minds of many people, and even a question they are preparing to ask. But someone asked first, looked around the crowd, and could see that he had a good effect of taking the lead. Among them was the Grand Magician Kabanbai, who sat in the middle of the front row, who did not think with a provocative thought, but seriously pondered the question: Why?

Lin continued, "Many of you here are my seniors, and they are far superior to me in terms of magical attainments. So I'm going to use magic to try to explain why I want to study math. ”

Look at those who were originally ready to settle down, and want to see what they have to say. Lin was also unambiguous, using his self-created magic whiteboard pen technique, to draw a three-dimensional, molecular structure geometric model in the air of the lecture hall. And explained: "What you see in front of you is a spell model architecture, and the specific appearance is presented. I believe everyone can see that this is the standard structure of the three-ring apprentice-level magic, the fireball technique. ”

At the same time, Lin used the water mirror screen in the lecture hall to display all the pages of the fireball technique in the association's standard textbooks. Most of the above is written description, and if the apprentice wants to learn magic, he must rely on the teacher's explanation and imagination, as well as countless attempts and efforts, to try to construct a spell model that is difficult to concretely present, and it is possible to successfully perform the fireball technique.

If you can show this three-dimensional picture directly to the apprentice, I don't know how much effort it will save. So regardless of the math, just the magic used for the structure and display in front of them makes many magicians feel that it is worth the ticket price.

But Lin Ke didn't end there, but explained one by one how the description of the fireball technique in the association's public textbook was transformed into that three-dimensional picture. And how much power should be poured into each node in order to exert the maximum power mentioned in the textbook.

After the apprentice-level fireball technique was completed, Lin said, "Apprentice-level magic is recognized as the most stable spell model, the easiest to cast, and the most powerful. Most people agree that there is no room for improvement in apprentice-level magic. Is that really the case? ”

Most of the magicians present sneered at such a rhetorical question, and no one answered the lecturer on the stage. Waiting to see the other party make a bigger mess, and then he will be angry, so that he can't turn over.

Lin changed his words at this time, and said, "Before discussing the improvement of the fireball technique, I would like to introduce you to a number series that I think is the most beautiful. As we all know, power is actually eight unspeakable things that pervade the deluded land and are omnipresent. Knowledge, power, authority, faith, wealth, dexterity, perception, mystery. Have you ever thought about the relationship between the eight powers? ──”

As he spoke, Lin took out a magic stone of the lowest level, the Red Yao level, and dangled it in front of everyone.

"Is there anything special about it when power is in balance?"

As he spoke, Lin used a trick that wasn't even apprentice-level magic, forcing the power out of the magic stone and turning it into a mist of light of eight colors. This is a demonstration that every magician will do when teaching his apprentices. The intention is to let the apprentice more intuitively 'see' the existence of power, and then understand the basis of meditation and feel the 'power'.

But this time, Lin forced out all the power contained in the Hongyao-level magic stone until the magic stone turned into a white crystal. However, it is not to allow power to overflow, but to restrain it. And the familiar way of separating the eight clouds of light and mist with different colors and staggered kneading,

When he saw the smallest black light mist, Lin reached out and grabbed it out and kneaded it into a small cube. At the same time, he said: "Everyone's perception of power is that some are more and some are less. And the black mass represents mystery, and it is also the rarest power. We have shaped the mysterious shape of the power light mist into a cube with the same length, width and height, and treat it as a unit. Then let's see how many units the amount of other powers is equal to. ”

Because it is consciously caught from less to more, the second captured power light mist, which is purple perception, is shaped into two unit cubes. Then there is dexterity, four cubes; Fortune, eight; Faith, sixteen; Authority, thirty-two; Strength, sixty-four; Knowledge, one hundred and twenty-eight. Capture all the light mist, a total of 255 units.

This operation was dazzling to everyone, but there was nothing surprising about it. Because they can do it themselves, even better and faster. But for what? Explain which powers are less powerful and which are more?
