"Is there any on me too?" Lydia asked curiously, holding her hand high.

"Of course, that's why we can run and jump. To be precise, lightning exists in all elements."

Lin En nodded, picked up a thin piece of paper, tore it into countless small pieces, and scattered them on the table. Then he picked up a glass ball, placed it on the palm of his hand and rubbed it hard for more than ten times, then moved it towards the shredded paper.

Under the astonished gaze of the crowd, the tiny pieces of paper trembled slightly, then flew up and were absorbed by the glass ball.

Seeing this magical scene, Lydia was the most surprised. She even suspected whether it was the effect of magic.

Lin En shook his head and said with a smile, "This is frictional electrification. You can also try it. The effect is very good when using glass!"

Hearing this, Lydia immediately picked up a glass rod and rubbed it dozens of times with her palms, imitating what Lin En had done just now. Sure enough, all the small pieces of paper were absorbed.

"Uncle Darren, I learned magic!" Lydia was so excited that she couldn't express it in words. She held the glass rod high up and shouted excitedly to the halflings who were controlling the airship in the distance.

Darren and the others were also amazed after seeing Lydia's results... By rubbing an object with the palm of the hand, it can temporarily gain the power to control lightning and absorb the object. To them, this is no different from magic.

Looking at this scene, Lin En didn't know whether to laugh or cry, and couldn't help but recall the famous saying in his mind.

If you don't understand math, physics and chemistry, life is full of magic...

Johnny, Alok and others began to experiment out of curiosity.

"Professor Lin, what is going on? Why is there an adsorption force on these things? Is it the power of thunder?" Philip couldn't help but ask.

In fact, he was quite surprised. Compared with those apprentices, he understood better how difficult it was to master the power of thunder.

After Lin En said that, it seemed like this thing was everywhere, and even ordinary people like Lydia who didn't know magic could use its power.

"The principle is actually very simple. When two objects rub against each other, because the atomic nuclei of different objects have different abilities to bind extranuclear electrons, one of the objects must lose some electrons, allowing the other object to gain extra electrons... In other words, the essence of frictional electrification is the transfer of charge..." Lin En said it as concisely as possible.

However, everyone present was confused.

What is this atomic nucleus? What are the electrons outside the nucleus? Philip was also confused. He shouldn't have asked...

"Lord Lin, can everyone master this kind of power? Can halflings do it?" Darren asked eagerly.

He also heard Lin En say "Everyone has electricity in their body" just now, but he understood it to mean that everyone can learn lightning magic.

How is this possible?

Alok and the others shook their heads with a sneer. In their opinion, it should be a natural law, just like a person will automatically fall to the ground after jumping up.

According to Professor Lynn's theory, this is the influence of the planet's gravity. In a sense, the continent beneath their feet casts a very powerful force field magic.

"I'm afraid it won't work with real magic. If you mean using the power of electricity with some knowledge and equipment like what I did just now, then of course it can work." Lin En said with a smile, and made some promises for them. "If you have enough knowledge, you might be able to use some instruments to replicate my electromagnetic railgun. If it is used to its full power, it will be comparable to legendary magic."

Everyone present looked at Lin En with strange expressions. This was too exaggerated.

Lydia even suspected that the professor was fooling them.

Legendary magic...she didn't even dare to think about it.

Lin En did not give any further explanation. Instead, he turned the glass ball in his hand and activated the magic sensor, but he could not detect any electric charge at all.

If you think about it carefully, this is normal. That thing is much smaller than an atom and is a microscopic particle. If it were really that easy, wizards would have already figured out electromagnetic magic long ago.

However, the technology of electricity can be highlighted first, and then its application in magic can be slowly studied.

Lin En thought to himself that now the [Lost Mist] on the sea has lost its original effect, which means that they will always face threats from the Vatican.

The exact time is uncertain. It could be two or three months, or it could be half a year. It depends on how long the deterrent effect brought by the Sea of ​​Fog can last.

If the Holy See took the initiative to send people to investigate, or even worse, if a merchant ship mistakenly entered the foggy sea, it would be exposed immediately.

As an important port and gateway to the land of wizards, Yieta Harbor will definitely be a major target of attack.

So you have to prepare early.

Compared to training more wizards, the power of technology is obviously the only way to improve combat readiness and deal with large-scale wars in the short term.

Although magic is amazing, a formal wizard needs to go through layers of selection and several years or even more than ten years of training. Even if they are blessed with protective magic, they may not be able to withstand several rounds of artillery fire. It is a waste to use them as cannon fodder on the battlefield. They are more suitable to be researchers.

Only great wizards and cardinals at this level can ignore the threat posed by artillery and even influence the outcome of a war to a certain extent. For these humanoid missiles, perhaps electromagnetic guns may be needed to deal with them.

Gunpowder granulation, internal combustion engine, electromagnetic technology... Lin En thought about it and found that there were too many key technologies.

As for those more advanced technologies? Lin En didn't even consider them, because they required the establishment of a complete industrial system before they could be developed.

And rubber... This thing is very important, but there is no such thing in the wizarding land. We can only think about whether we can use magic to solve the problem of materials science, and then use alchemy to replace some of the complicated work.

The most important issue is education. Workers who are familiar with and have mastered certain knowledge are the foundation for building an industrial system. However, he obviously does not have enough time, and it takes too long to teach from scratch.

The only way is to call back all the wizard apprentices and even formal wizards who have graduated for re-education! (PS: Thank you for your rewards, subscriptions and voting support. Three chapters today and more tomorrow.) (End of this chapter)
