In an awkward, treacherous atmosphere, the bell rang for the end of class, announcing the end of today's class. Lin looked at the small clock hidden in the corner of his field of vision in surprise, and it still took more time than expected to reinterpret the fireball technique. Luckily, it was completed within the course time, so I don't have to wait for tomorrow.

Lin scattered the whiteboard handwriting in the air, and sent the power mist back into the magic stone that had turned into white crystal. In fact, this kind of action is very wasteful, because the power that is stored back in the magic stone will only be less than the original release, and it can only be recovered between three and forty percent, and the rest is wasted.

But this can't be helped, these powers have no use, and it is a waste to let them drift away, and it is as much as you can recycle.

After roughly tidying up, Lin Xiang was still sitting in his seats, and the magicians and non-magicians who had not left the scene displayed a web address for the forum and a small piece of disordered characters on the water mirror screen in the lecture hall. At the same time, he said: "This forum website is built under the block of Kabambai College, which is an affiliated section of the mathematics curriculum. Those who participate in the course today can use the password at the end to obtain the read-only permission of the first class, which is limited to those in the class, please do not spread it arbitrarily. This is the outline of today's lecture, which includes all the calculations for the improved Fireball technique. The calculation method used above is the course to be taught in the future. However, the improvement of the spell model for magic will only be talked about once. The purpose is to show you that math is useful, but it won't be covered in the future. I will save the last ten minutes for the next ten minutes to answer at least one question. If the question could be answered simply, of course there would be a few more. That's it for today, I'm going to find a way to fix that hole in the wall. I'll see you tomorrow after class, everyone. ”

Although someone tried to end the day with a light-hearted note. But the students in front of me are not at all like the universities of the earth, and they run out as soon as they hear the bell of the end of class. I don't know what their silence represents, is it the lecture just now that has ruined their three views and is doubting life? Or did you find a flaw in your words and are preparing to fight in the ring?

"Lord Tripwood." As the master of the Academy, the Grand Magician Kabanbai opened his mouth.

Someone thought that this old-timer was going to discuss the issue of repairing the wall, and hurriedly said: "Your Excellency Kabanbai, I will repair that hole as soon as possible, please don't worry." ”

"No, I'm not thinking about that. And you don't have to worry about that kind of damage, there are special personnel in the academy who are responsible for repairing it. The old magician asked about something else. Have you already done similar calculations and optimizations for all sixty-nine apprentice-level spells from one to three rings? ”

"Well, no. I've only done about a dozen or so that I'll use. Although in order to become a full-fledged magician, it is mandatory to learn apprentice-level magic. But it really comes in handy there, and it's only part of the individual tactics that form it. Besides, some of the three-ring magic itself is very complex and not so easy to parse and improve. ”

"When were the ones that have been completed?"

"I did it when I was still in the Tower of the Great Sage. After all, it was only at that time that I had more free time, and I have been traveling since then. I can't calm down to do calculations during the trip. ”

"How long ago was that?"

"If you really want to count the time, it was almost five years ago." Someone said lightly.

"This ......" Rao is well-informed, and the great magician Kabanbai can't imagine how this man thinks. You've wasted five years of research on such an important piece of research. Not even the slightest rumor was revealed. ”

"Important?" Lin chuckled abruptly. After apologizing, he apologized and said, "Your Excellency thinks too highly of such an achievement, but in fact, there is nothing remarkable. ”

"How could there be nothing remarkable, this perfect spell model architecture,—"

Stretching out his hand to stop the words of the great magician Kabanbai, Lin said: "The so-called perfection itself is imperfect. You agree, Your Excellency. ”

"Perfection itself is imperfect ......" repeating such a simple sentence, Kabanbai seems to have groped for some unclear truth. What makes her imperfect? ”

"Magic doesn't exist on its own. With that said, you should get the idea. Lin further said: "The power that exists everywhere in the world is not actually a state of static equilibrium. In different environments, the amount of each power can be high or low. No matter how perfect a spell model is, it can't avoid being affected by the environment. ”

It is true that when environmental factors are added, the complexity does not increase exponentially, but hundreds or thousands of times more difficult. I'm looking for an answer, is it a change of environment and start all over again? Jiujiu Library

Lin said: "Besides, this is only apprentice-level magic, isn't it too much to require apprentices to have such control and construct a perfect spell model." Speaking of which, it was only after my apprenticeship that I realized this truth. For them, whether it will be used or not is more important than perfection. As for the actual use of it, if we are in a hurry, we are not allowed to craft a spell model. In other words, this is just a product that can be used to bluff people for teaching or research. That's why I didn't continue to count all the unfinished Ring 1 to 3 apprentice-level magic. ”

The question of reality made the great magician Kabanbay speechless. He struggled and said, "Even so, Your Excellency can hand over such research results to the association, and let the people who use and learn it judge for themselves." ”

"Exactly that's something you can't do." Someone said categorically.

"Why!" The Great Magician's face flushed, and he said with rare excitement.

Someone was taken aback by this, fearing that the old man would have a heart attack, so he walked away. hurriedly reassured the other party and explained: "Your Excellency, calm down first and listen to my explanation." As he spoke, his left hand and right hand each used a whiteboard pen to show the spell model of the fireball technique, and Lin asked, "Your Excellency, can you tell the difference between these two spell models?" ”

Kabanbai, who had calmed down, squinted and observed, and after comparing the memories in the class just now, he said, "The one on the left is the original spell model that you constructed according to the textbook issued by the association. And the right hand is an improved version. The difference was subtle, but I could tell. ”

"Oh, what a great magician, with a sharp eye. It is also true that as you said, the left hand is the original, and the right hand is the improved. So here's the problem, if I want to hand over an improved version of the Three-Ring Apprentice-level Fireball Magic knowledge to the Guild. Asked by the mages who censored me, what is the difference between the architecture of the two spell models, and how can I answer? ”

"Of course it'......" Kabanbai suddenly stuck.

It wasn't just the gray-haired magician, none of the magicians who listened to the lecture left, and their minds were different, but Kabanbai's questions and thoughts were indeed their own questions and thoughts. There are even people who intend to seize such intellectual rights, as long as they are handed over to the association first, relying on their own networks, no one can shake the fait accompli, and this honor will belong to him.

But...... How do you explain to the guild how the improved spell model differs from the original?

Lin said, "That's it. How am I going to explain to the Magic Censor who doesn't understand mathematics that every angle and distance of the improved spell model has been carefully calculated to get the most perfectly balanced result. And most importantly, can the other party or someone else reproduce such a result? If the learner doesn't know how to calculate, and even the person who teaches doesn't, can they tell the difference between the two models? ”

The truth of the matter is so simple. Many old pedantic magicians only feel a tightness in their chests and want to vomit blood. People scolded implicitly: It's not that I don't teach, it's that you don't understand.

Someone continued to pursue: "In the same way, why did I have the knowledge to teach the P language when I was in the Southwest Peninsula, but I didn't do it when I came to the Holy City. I don't even choose to teach many people what they want to learn from me, including the improvement of the Magic Tower, the use of magic circles and magic runes, or the construction of airships like the Sid. If I don't understand mathematics, I have something to talk about and something to teach. ”

In the crowd, one person reluctantly said, "Isn't there an easier way?" ”

Lin knew who said it, but didn't know the name. It was a magician who was much younger than the old man present. Although from the outside, the other party is still older than himself. Hearing this feeble moan, Lin laughed angrily and said:

"I don't want to learn mathematics, I just want to directly use the knowledge that can already be put into practice, which is also simple, and the Tower of the Great Sage stands there. Everything I heard about the tower was once again made public. I have no objection to this. Therefore, if you have any need for the magic tower, please copy it, and it will definitely play the same role. If it doesn't meet the standard, I can only say that I didn't copy carefully enough, and I can't be blamed for that. ──”

It's like saying that someone is going to be angry, and someone is going to keep going," - Sid's airship, I'm sorry, there are trade secrets on it, and I don't want to make it public so soon. After all, as a weapon to protect civilization, the magic tower increases its strength, and it will provide more protection for civilization. However, if the design of an airship that is too good is widely circulated, it will only become an advantageous weapon in war, and the gap between the powerful and the weak will become more obvious. I have a small nose and small eyes, and the peace of the land has nothing to do with me, and it's not that I don't hand over this knowledge, but what price is the person who wants it ready to exchange for? ──”

Glancing at it, some people are excited, some people are thinking. It looks like a sub-offer. Lin sneered.

I think a magic tower, in exchange for the full design of the Sid, is a very reasonable bargain. Other than that, I don't think about it. As for the flashing spell, the elusive magic of the Gaiden, it was the result of research with the World Tree Vadwo. I can't make that knowledge available to the world without the consent of that One. As soon as someone obtains the consent of the high seat of the turtledove alliance, I will immediately present the full set of knowledge with both hands, and I will not hide it from myself. Or does anyone think they can capture me and take the knowledge from my head? ”

"yes, why don't you give it a try." A defiant voice came from the crowd. At the same time, it has the power to fluctuate, directly touching the sensitive nerves of all magicians. Almost instantly, the lecture hall was full of colors, and all the mages activated their own magic protection!
