Magic Tower Starry Sky

When the low-pressure atmosphere covering the Great Sage's Tower was swept away, it finally ushered in another wave of vitality.

Like a bee, the figure flying around the tower diligently, once again organized the order and the environment to be meticulous and spotless. Of course, the girls spend more time by Fen's side, the former demon king, the lich who was revived after a thousand years.

Does this make some teacher guy feel hurt, or lonely? Or lost?

Regardless of what the gloomy mood was, what Lin couldn't accept the most was that the two girls found doubts in the process of practicing the third-level magic of the apprentice level, and went to ask a certain lich who was addicted to coding.

It is tolerable, which is unbearable. Even if he is a lich, he does have richer knowledge of magic than that person; even if he is a "sister" as the apprentice said, he seems to be born with a friendly aura. Even if...

There are many reasons for two girls to do this, but I am your teacher~

Lin cried out weakly in his heart.

In order to boost Fu Gang... oh, no, to boost Shi Gang, Lin sneaked around the two young apprentices during the day. Especially when they were practicing magic, they pretended not to care, but pricked up their ears.

And someone's small actions, in the eyes of the other three, are... childish?

Unexpectedly, Finn Tikal, Hallumi, and Kaya all ignored such behavior. Even without any discussion between the three of them, there was just a tacit understanding, watching someone play monkey games.

Just one afternoon, a long-awaited opportunity came.

The two girls were working on the same subject, the tornado technique of apprentice-level three-ring magic.

To be recognized as having mastered the magic at the level of the third ring, it is not only about using it, but also on a certain scale. Tornadoes, earthquakes, and gravity changes, these are not like gathering water and burning fire in the first ring, just gather the most basic elements and you're done. Without a certain range of influence, the effects of these spells would be nothing.

For example, the Earthquake Technique, even if it cannot shake the sky and cause the city walls to collapse, or the castles and towers to collapse, at least it must be able to make people unsteady. If only ultra-small-scale earthquakes can be achieved, what can be done? Could it be that shaking a woman with **** can be called an earthquake technique? People can create waves by jumping on their own, so why don't the mage cast magic.

It is so difficult that the three-ring magic has become a natural moat for magicians and magic apprentices. How many apprentices have fallen here because of their talents or because of resources, and they have been unable to crown themselves the title of official magician for the rest of their lives.

And this is exactly the dilemma the two young apprentices are facing now, unable to create a large enough tornado.

In this regard, Fern, the lich from thousands of years ago—although she was dismembered and imprisoned for a long time, her dark age of dominion also has hundreds of years. ──There is no good teaching method, which is what the old magicians would say, concentrate on feeling the existence of the wind, and use mana power to guide them. Or your power accumulation is not enough, concentrate on meditation.

Speaking of it, this is a misunderstanding that a magical genius like Fen cannot understand.

It's like throwing a fist. If he is big enough today, his body is strong enough, and his muscles are well developed, then any fist he throws can easily hurt people, or even send them flying.

Doesn't that thin little man have no human rights? Of course not. As long as you go through training, learn the correct punching posture, and hit the vital points accurately, even a small person can beat opponents. Although talent is not enough, it can still be made up by hard work.

The question is how hard? This is not something that those who rely on talent can easily answer, because they don't need to consider this aspect. With extra energy, they will think about how to beat others more painfully, or train themselves to be bigger. As for throwing a fist, it seems like instinct to them.

The same situation also exists in the world of magicians. Fern could share the magic of the tornado with the two girls, all the variations and subtle manipulations. For the same spell, she can also provide many different spell models, each with its own advantages and disadvantages. People can adapt to local conditions and choose the most suitable one to use at the moment.

But the premise of all this is that magic can be cast. It is necessary to think about the follow-up improvement plan.

The two girls invoked the magic power in their bodies, which was too weak for an official magician to bear to look at directly. They kept summoning the spirits and elements of the wind, hoping that they would spin up according to the imagined trajectory and form a tornado. But it was a failure time and time again. The tornado didn't happen, and it only made people feel the ubiquitous oppression in the air.

Of course, as a lich, Fern wasn't just staring aside. She tried to modify the spell model of the tornado spell, and then explained it to the two girls, hoping to find a way for the girls to succeed through constant attempts. It never occurred to her that such actions might be counterproductive.

Apprentice-level magic, the common point of its spell models is that they are easy to cast. Although on this basis, controllability and various delicate changes are sacrificed. However, after hundreds of years and countless improvement of magic pioneers, it can be said that apprentice-level magic has reached an extreme under the aforementioned premise.

This is also the reason why magic such as gravity change and time suspension can be cast by an apprentice. Because the apprentices just follow the example, rather than really understand the principles and meanings behind it.

And Fern used his own ideas and experience to improve, and kept instilling it to the two young apprentices who had not yet made up their minds. As a result, Harumi and Kaya became even more confused, and the distance from success became more and more distant, but the parties were at a loss.

So Lin had no choice but to jump out and save the hard-working people at the bottom, so that they would not be detoured by those brick-and-mortar bootleggers.

"cough!"

He coughed next to him, hoping to attract attention. The result failed... The three women are still discussing themselves.

"Cough! Cough cough!"

As a last resort, Lin coughed more to remind others. Finally, three women glanced at him at the same time, two with dissatisfaction and one with disdain. Fern said angrily, "Tell me what you want to say."

"It's not okay to cast magic like this." According to the tradition left by the counselors of the Three Kingdoms period, there must be a slap in the face at the beginning, so that people will pay attention to the following content. As expected, seeing the three expressions turned into disgust, and the corners of their mouths all pulled down, Lin knew that half the battle was won. The other half also wants to succeed, but the prerequisite is not to be slaughtered by the former devil...

"Magic is an act of imitating nature and then changing it. Have you ever thought about how tornadoes happen in nature?"

After asking the question, Lin paused to give the three of them time to think. Because looking at Fern's expression, he knew that this lich hadn't thought about this matter; let alone the two girls.

After a while, seeing that the silence was about to turn into embarrassment, Hallomi took the lead to break the deadlock, and tried to answer: "Isn't it just the wind whirling around?" The words were accompanied by movements. She stretched out her index finger, held her right arm high, and made a few exaggerated circles.

"Puff, of course not." After Lin gave a negative answer, he stopped waiting for everyone to think. On the one hand, they are also afraid that they will lose interest, so they simply break their cans and don't continue to listen to someone's big talk. So Lin said directly: "Wind, that is, what is the ubiquitous air that we depend on for survival, let's not discuss it first, let's talk about its characteristics first. Wind is like water, it is a fluid, there is no fixed shape. Since it is a fluid, some characteristics of wind can be understood in the form of water. You can accept this premise."

Kaya, who was puzzled, asked in a rare way: "Why do you need to use water to understand?"

"Because wind cannot be seen under normal conditions, but water can be observed with the naked eye. Returning to the topic, if it is water, it must form a vortex. In addition to being stirred by hand, under what conditions in nature, water will form vortex?"

"A place blocked by stones." Harumi replied quickly.

"That's right. What else?"

"Is there a pit at the bottom of the water?" Kaya tentatively replied.

"Correct. To explain it in terms of mechanics, flowing water has a force acting in a horizontal direction. If the river is smooth all the way, then there is a force acting in a single direction. But at this moment there is a pit in the river bed, and the water in it will also It is flowing. At this time, in addition to the force in the horizontal direction, the water flow also needs to exchange the water in the pit, so there is a force in the vertical direction. Under the mutual influence of the two forces, a The oblique force acting on the water flow is a vortex."

Not to mention the genius of Fen, she almost emptied all of Lin's modern knowledge of the earth~www.wuxiaspot.com~ Although the two girls are only at the level of elementary school students in mathematics, algebra and equations have not yet been taught. they. But in the past, for some explanations in magic teaching, simple mechanics and the three laws of motion have also been mentioned to them.

So about the formation of the water vortex, they thought about it for a while, then nodded to express their understanding. Lin Cai went on to explain: "How do tornadoes form in nature? The wind is not like water, it will spin around because of a few stones."

"That is to say, there is a force in the vertical direction." Kaya interjected. Although the expression has not changed for thousands of years, there is some excitement in the tone of voice.

Lin was not impressed by this kind of interaction, but praised encouragingly: "That's right, that's right, there is a force in the vertical direction. Then where does this force come from? Well, I don't need you for this one." We guessed, because it involves a feature I haven't said yet, that is, hot air rises and cold air descends. When the sky is thick enough, the clouds formed by water vapor condense a lot of cold air, and the ground It is under the sun’s exposure that enough heat is stored and the temperature of the air close to the surface is increased. When a large amount of cold and hot air is exchanged in the vertical direction, and then the force in the horizontal direction is stirred in, a tornado is born.”

While explaining, Lin also brought everyone outside the tower. Using magic to gather a rain cloud in the sky, and at the same time using the improved special magic combined with fire and light to increase the temperature of the ground. The whole environment became stuffy and extremely uncomfortable, and even the heat rising from the ground gave people the illusion that the whole scene was swaying.

This situation did not last long, and the fallen leaves and dust began to swirl, while the clouds in the sky showed a funnel shape and extended downward. A tornado is starting to form!
