Lin said with a smile: "It seems that everyone doesn't understand what this has to do with mathematics. Everyone knows how to multiply in the four operations. Today, let's introduce a new concept: power. When two identical numbers are multiplied together, we can count as the power of a certain number. Three identical numbers are multiplied to the third power. And so on. And the power of zero of all numbers is equal to one, as for why, we will discuss it later, let's remember it today. ”

While explaining, Lin gathered the powers scattered in the air and confined into cubes according to the same color.

At the same time, using the whiteboard pen technique, first write down the zero power of two in front of the black mystery is equal to one; The perception of purple is two once square is two. When writing down the quadratic of two in front of the blue dexterity, Lin also deliberately asked the granddaughter of the self-proclaimed mathematician Kabambai, who was also present: "Two times two?" ”

"Equal to four."

"Clever." Lin praised a sentence, wrote down the answer, and then continued to write the next one, and then the next one. As the power of two was answered one by one, the magicians who realized what could not sit still. They looked in disbelief at the power that had been thought to be mere but not regular, and a ...... appeared I don't know how to describe the rules.

When the sequence of '2^0=1,2^2=2,2^3=4,2^4=16,2^5=32,2^6=64,2^7=128' was completed, Lin Xiao pushed forward the number series written in the air with a tabula rasa pen, together with the power light mist that was bound into a cube, and said, "Everyone, this is the only proportion of power that can maintain a static balance without attributes when it exists in the magic stone. No matter what level of magic stone it is, orange ingots and yellow clothes are the same, there are no exceptions. ”

Without waiting for the magicians to fully understand what they were seeing, Lin took the static balance ratio of power as a starting point, and began to adjust the spell model of the three-ring apprentice-level magic, the fireball technique.

In the standard textbook, all the nodes of the fireball technique, what is the power ratio, and how far apart is the straight-line distance between the two nodes. On the basis of mechanics, vectors are introduced to illustrate how attractive they are to each other. What adjustments need to be made in order to strike a balance. Sometimes it's to change the power ratio of a node, and sometimes it's to change the distance between two points.

If the structural link between two points is not a straight line, but a curve, the equation for the curve must be calculated. and how curvature affects the imbalance of power, and how it can be rebalanced.

If you start to expand the scope of consideration, when there are three or four points, you will start to have the problem of angles between different vectors. The tool to be used at this time, of course, is trigonometric functions.

But there are many aspects to consider, and when the whole body is affected, it is necessary to rely on simultaneous equations to arrive at the only solution. Sometimes, in order to find some tricky solutions, of course, the formulas of advanced mathematics come out, such as calculus, analytic geometry, vector algebra, etc., which are dazzling and blinding the people who listen to the lectures.

In fact, when it came to optimizing apprentice-level magic, it wasn't as easy as it is today. That was to bring the lich and even the two girls in to study and brainstorm together to figure out the best solution based on the apprentice-level spell model. The optimization of each spell model took a considerable amount of time to complete.

And what you do today is like beating an old magician alive. Although they could not understand the computational process, or why the relationship between two nodes could be mathematically written and transformed, they could understand that the result of the calculation was desperately moving closer to the static equilibrium ratio of power described earlier.

The magicians who are able and willing to sit here are actually the kind of masters who study their personalities, not the kind of people who love to fight and kill, and do things without brains. Research, on the other hand, is rigorous, and a little more, a little less, may cause a difference in the results.

It is this kind of obsessive-compulsive personality, watching the changes in numbers finally become the perfect static balance ratio, that makes them feel a strange sense of beauty, and ...... Pleasure? Some people even forget that they are here to find trouble. They are selflessly immersed in the world of numbers, looking for the beauty of harmony.

And the person in front of him said that improving apprentice-level magic was really just an improvement. The spell model is still the same spell model, it's just a change in angle, a change in length, and all the changes are quite subtle.

Even a single look at the before and after models makes one wonder if such a change is necessary. But when presented in numbers, it is precisely this little change that brings about a earth-shaking change.

It's not like no one has said before that you can improve apprentice-level magic. But as soon as the results come out, it's just another magic, talk about improvement.

Today, however, they took a fresh look at improving magic. That apprentice-level magic, which is said to have been tempered for thousands of years and cannot be changed, still has so many imbalances hidden in it! Seeing that everything was corrected, everyone was comfortable. They even had the illusion that even if the magic was abolished, it didn't seem to matter that much.

When the last change adjustment is completed, all the associated nodes and links are perfectly balanced. At this point, the fireball technique improvement operation was over, but everyone secretly sighed in their hearts.

In fact, in the process of calculation, sometimes one node reaches equilibrium, but the other balance is broken. For this terrible state, everyone is almost out of breath. Thankfully, the result was perfect. Pi Phi Reading.com

Someone who is in charge of the calculations doesn't suffer from gains and losses like everyone else. Because it's like playing magic blocks, even if one side is completed, in order to complete the other faces, the finished side must be destroyed. For him, the result is already known, so there are no superfluous emotions.

Lin just smiled at everyone at this time, holding up the improved fireball spell model, and said, "Which senior can use clod magic to make a target?" ”

As soon as someone said something, the air in the lecture hall had the power to gather, silently condensing into several huge stones.

Spell models constructed using magic whiteboard pencils are not really magical, as the powers in each node are only written in numbers. But Lin controlled the eight abilities that were sealed in the air, that is, those that were forced out of the Red Yao-level magic stone at the beginning.

He didn't dare to pour the power of the entire redstone into the spell model, but only extracted a trace and infused it in proportion to the needs of each node. The fireball spell is in the air, taking shape with the help of a spell model.

Except for a few people present who did not have the identity of magicians or even knew magic, everyone had been immersed in magic for more than ten years.

Most of the time you may be fighting with support magic attached to you, but as an outgoing attack magic, fireball can be said to be an eternal classic. So everyone knows what the fireball they cast on themselves should look like.

But the fireball in front of him is really a little different. The fireballs released by ordinary magic apprentices are mostly the same as the fire of a ring of magic. It's just a flame condensed in the hand, which can be thrown as a ball. When you reach the level of a magician, you have a deeper understanding of magic and know where the key is, and the fireball will look like the 'fireball' should be.

But the fireball spell that the magician cast, the spell model is the one everyone sees, and the power is also extracted from the magic stone, which means that he has no other room to cheat. And that improved version of the Three-Ring Apprentice-level Magic Fireball Technique could actually condense a fireball that was like substance. Everyone couldn't help but be curious about the attack power of this fireball.

Lin controlled the magic, aimed at any clod of dirt, and with a flick of his finger, threw the fireball out.

I don't know if the unknown magician who cast the clod magic was too careless, or if the improved version of the fireball spell was too weird. The fireball, which was unusually stable in the structure of the spell model, actually smashed into the clods of earth, and smashed all the way through the outer wall of the lecture hall and flew outside......

For such a result, everyone still doesn't understand the value of this new version of the fireball technique. No! It should be said that the mathematical method that improves the structure of the spell model is the real value.

But the man who used the magic was dumbfounded. The power of fireball is the splash damage after exploding, although using this magic indoors can affect many people. But considering that most of the people present were magicians, it was impossible not to have the means of protection against unexpected situations.

Secondly, he also has a defensive backhand, which is enough to shelter those who are not magicians. What's more, the power used by this fireball is quite low, almost just past the threshold for activating magic, so it won't be very powerful. Even if you really can't dodge it, it's okay to deal with a few blisters.

But what now? Smash straight through the wall! If the original target was a wall, it wouldn't be surprising to smash through it, but it was aimed at the clods of earth that the magician had magically created first!

Although the clod of earth is only one ring of magic and the fireball is a three-ring, the level of magic does not mean the strength of the mana depending on the user and how to use it. And it was smashed through by a fireball technique with minimal power, it wasn't a clod of dirt, it was tofu.

And even more surprising than Lin was the magician who performed the magic of clods of earth. Although he hasn't mixed with the second golden spike line, in terms of strength and knowledge base, he can be regarded as the best among veteran magicians. He didn't release any water from the magic just now, and even added some ingredients. In addition to really wanting to try the color of that improved version of the fireball technique, there are also some thoughts that I want to see someone mess up.

But! The ending was not what he thought......

Luckily, there are many magicians who also perform clods of earth, and all of them are the kind of silent magic. Therefore, except for his own heart, no one knows who used the clods of earth condensed by the magic in the air. It saved him from a humiliating disaster. So he tried to pretend to be calm and not let others have a chance to see it.

Faced with the damage he created, Lin said curtly: "Well, that breach, I'll fix it later." ”
