On the carriage back to the courtyard from the assessment place, Grand Magician Camilla kept looking at Xu Yi with that slightly weird smile on his face.

Xu Yi was uncomfortable with him, and couldn't help but say, "Your Excellency the Great Magician, what are you laughing at? I used this to pass the test, but you also approved it last night? Now you can't always say that I cheat, right?"

"If I thought you were cheating, I would have debunked you just now. Grand Magician Camilla shook his head and said, "I just still think this matter is too unreasonable, why do you obviously use simple wind magic, but just a small magic machine, can cause fluctuations in the electric magic element, so as to release the electric magic? What's even more outrageous is that the power of this magic is still so great, and it even exceeds the limit of your magic power." ”

"So I didn't control it at all. Xu Yi spread his hands. "If it weren't for the magic protection in the examination room just now, these lightning bolts would definitely be flying around, and maybe they would hurt someone. ”

"Hurt whom?" said Grand Magician Camilla, sneering. "Although the power of your magic is indeed very great, but it is not deliberately controlled, the power is too scattered, and the actual lethality is probably not as good as the sixth-level magic, who can you hurt?"

"What if I can control it completely?" Xu Yi couldn't help but ask.

Grand Magician Camilla thought about it for a moment, and her expression became cautious.

"If you can control it all...... I'm afraid even I'm going to have to deal with it seriously. ”

After a pause, Grand Magician Camilla stretched out his hand to Xu Yi: "Show me what kind of generator it is, I will study it carefully." ”

Xu Yi rolled up his sleeves. Revealing the small homemade generators that were tightly tied around his arms, he took one of them and handed it to Grand Magician Camilla.

The brainchild of this small generator. It came out of nowhere that night when he was thinking about how to solve the street lamp problem.

On Earth, electricity is a very important component of modern industry.

Xu Yi had always wanted to use magic power and the power of the magic array to make a magic machine. to imitate those industrial machinery on the earth, so when thinking about street lights, I still maintain this mode of thinking.

Later, when he found it difficult to solve the problem that the street lamp needed to face, this thought suddenly flashed through his mind.

The electricity on Earth is actually converted from other power sources, so according to this inference, it is obviously very possible that magic will be converted into electricity.

The first thing that came to his mind was not electric magic, but a generator.

The reason why the generator was able to discover it was that the rotating closed coil continuously cuts the magnetic flux of the magnetic field and generates a magnetoelectric induced current, which converts kinetic energy into electrical energy.

On Earth, the kinetic energy that provides the magnetic field for the cutting of a closed coil is mainly the thermal energy provided by the coal, the impact force provided by the water flow. There is also some wind and nuclear energy.

Xu Yi's first thought was wind energy.

Therefore, according to the working principle of the wind turbine, Xu Yi finally made a small wind energy generator according to the basic structure of the wind energy generator after several days of research.

When Haynath brought Kennard, Sophia, and Hank Wilson to visit him in Bunta City some time ago, he was studying it.

As for how to provide wind energy, Xu Yi temporarily thought of using the wind magic array, and the wind energy provided by the wind magic array through the guò wind system magic array pushed the coil to rotate to cut the magnetic field.

The initial reality was quite successful, and when Xu Yi successfully used the wind magic array to push the coil, this small wind turbine actually released an electric current.

However, Xu Yi's research has only stopped at this step for the time being. He has no idea how to direct the current next, how to store it, how to increase the amount of electricity generated, and so on.

Originally, he wasn't in a hurry, and he planned to take the time to study it slowly in the future, but yesterday Grand Magician Camilla told him that he had to conduct a high-level magic demonstration for the qualification examination of a senior magician. In desperation, he thought of this solution.

In fact, although he didn't really master any high-level magic, as a magician, his magic power was raised to the level of a seventh-level magician. Of course, he also had some research on high-level magic.

And as he said, he's a bit better at wind magic. Therefore, more attention is paid to high-level magic, and it falls on electric magic.

During the test of a small wind turbine, Hui also made an unexpected discovery. The electricity emitted by the generator is very similar to the electric magic elements described by electric magic.

So he tried to manipulate the electricity by manipulating the electric magic elements.

The result was shocking, he was actually able to manipulate these currents through guò magic!

This made Xu Yi immediately understand that the so-called electric magic element actually refers to the electric charge in the space at all!

According to the theory of electric magic, magicians use magic to affect electric magic elements, which is basically to use magic to forcibly affect space and create electric charges for control, so as to generate electric magic.

There is a very strong evidence for Xu Yi's inference, that is, in thunder and rainy weather, magicians who are good at electric magic will always be particularly powerful.

Therefore, when Xu Yi was thinking about the problem of high-level magic demonstration, he thought of the real yàn that he had done before.

And yesterday afternoon, he proposed his idea to Grand Wizard Camilla and Steele.

Although Grand Magician Camilla and Steele didn't quite understand and couldn't believe his idea, when they saw Xu Yitong Guò a small wind generator actually generate electric magic elements, and then use magic to manipulate them, the two were shocked but had to admit that this was indeed a good way to hide from the world.

Of course, just a small wind generator does not generate much electricity, and the generated electric magic elements are not enough, even if you use electric magic, I am afraid that it will be suspicious because the power is too small.

So for the sake of safety, Xu Yi immediately asked Director Ram to purchase a bunch of materials for making zuò small wind generators, and with the help of Grand Magician Camilla and Steele, he made as many as twenty additional small wind generators, and then wrapped them around his two arms. Two wind gensets were generated.

During the high-level magic demonstration just now, Xu Yi directly injected magic into these twenty small wind generators. Activate the wind magic array inside, causing twenty small wind generators to generate electricity at the same time. Then a large amount of electric magic elements was generated in an instant.

As for what follows, it's much simpler.

Although Xu Yi's magic power can't completely control such a large amount of electric magic elements for the time being, it is still no problem to achieve basic guidance.

He only needs to use all his magic power to control these electric magic elements and burst out according to the basic principles of electric magic.

This has proven to be fantastic.

Tong Guò did an emergency training under the guidance of Grand Magician Camilla yesterday, and Xu Yi cast this electric magic at the high-level magic demonstration, just relying on the power shocked everyone, and easily passed this assessment.

But even though he saw Xu Yitong's small wind generator generate electricity countless times, Grand Magician Camilla still couldn't understand the principle.

Taking over the small wind generator handed over by Xu Yi, Grand Magician Camilla took it in his hand and looked at it several times. The body magic power moved slightly, and the wind magic array in the small wind system generator was immediately urged, and the coil immediately began to rotate at high speed, emitting a buzzing sound.

In the blink of an eye, a trace of electricity is generated from it.

Grand Magician Camilla pondered for a moment, and as soon as the magic power was activated again, small lightning flashed in his hand, which looked very gorgeous.

"Xu Yi, how did you come up with this thing? It was a complete reversal of my perception of magic. After stopping the magic urge, Grand Magician Camilla looked at the small wind generator in his hand and couldn't help but ask Xu Yi.

Xu Yi glanced at Grand Magician Camilla, and then at the small wind generator in his hand. I thought that if the people on the earth knew that the magicians on the Sainz continent could directly manipulate the current charge and generate lightning, I was afraid that it would also be ruined.

To know. What child on earth has not been taught from an early age that this one cannot be touched blindly if there is electricity, and that one cannot be touched blindly when there is electricity.

A person will be electrocuted by an electric current. Already common sense on Earth.

And in this world, powerful magicians not only do not get electrocuted. It can even manipulate lightning, which will also subvert the common sense of people on Earth.

For example, Xu Yi never thought that he could actually manipulate the current generated by the generator by his own will, and even manipulate these currents as a lethal weapon.

After thinking about it for a while, Xu Yi found that it was really impossible to fully explain the principles of the generator to Grand Magician Camilla, and he couldn't tell how he knew these principles, so he had to answer vaguely: "This is just what I found when I was idle and bored doing all kinds of magic mechanical practices, if you ask me the specific principle, I actually don't know very well." ”

Grand Magician Camilla didn't think much of it, nodded, glanced at the small wind generator in his hand again, and stuffed it into his pocket unceremoniously.

"This thing for me to study and study. ”

Of course, Xu Yi could only nod yes.

However, after glancing at Camilla's Grand Magician, Xu Yi suddenly thought of an even more strange question.

According to the magic theory on the Sainz continent, a powerful magician like Grand Magician Camilla can easily use large-scale electric magic, and even magicians with a higher level of electric magic can also use forbidden spell-level electric magic, which is comparable to nature's lightning.

But if these powerful magicians were allowed to turn around and control the smooth output of these electric magic elements through their magical powers, wouldn't they be able to become a generator themselves?

Thinking of this, Xu Yi couldn't help but think of a picture.

One dark night, when the power went out for some unknown reason, Steele shouted upstairs, "Grandpa, the power is out, you can send some electricity." ”

Then the venerable and venerable Grand Magician Camilla answered, and the magic power worked in full force, and the electricity was running all over his body.

In the blink of an eye, all kinds of electric lights and appliances in the house are back on the light...... (To be continued......)
