Reincarnation with AI (Unemployment-Free)

Chapter 95 Light Dance

Lightning is a very mysterious phenomenon.

It's like a rainbow, but different; it's even more mysterious than a rainbow.

Rainbow might offer a few words of explanation, though she only vaguely understood them, but Lightning was completely baffled.

Often, the lightning ends, and people are startled by the sudden flash and the subsequent loud noise.

Even if you happen to see it, you cannot observe the complete process of lightning occurring.

Lightning occurs at speeds far exceeding those that the human eye can perceive.

lightning?

It's that thing that just flashed by.

Rudius now realizes that the lightning he saw in his past life was actually no more than the rainbow.

It was only because of his beautiful expectations of rainbows that Rudius had such a strong preference for them.

Without the help of AI, if Rudius were to explain, he could only utter the words "potential difference" and that would be the end of it.

Although the analogy is made with wind, wind is simply the result of air movement. Just like when I push you, you feel the pushing force, which is very intuitive.

Why does it start flashing and making a popping sound when air is replaced with electrons? And why is it so fast?

Rudeus couldn't explain lightning to Sylphie because explaining lightning would involve electrons, and he himself didn't understand what they were.

Lightning appears as a line, but there are no wires there. How can this be explained by high school physics as the movement of electrons?

However, with the help of AI, understanding the principles of lightning is far simpler than understanding rainbows, at least for Rudeus.

With the availability of protective measures, Rudius's progress in this area can be described as rapid and leaps.

Hilfi has also completed the preliminary education on triboelectricity and magnets.

Rudius also bought two small magnets and gave them to Hilfi. Hilfi had already played with rubbing amber with fur to attract fragments and also manipulated the magnets to attract iron nails.

"Lightning is indeed like wind, but it is also different. Air can be easily moved, but the thing that causes lightning is very difficult to move." Rudius pondered for a moment and decided to invent the term "electron" anyway, otherwise it would be too troublesome to explain.

So they chose two similar-sounding languages ​​from another world and combined them into this vocabulary: "Let's call this moving thing an electron."

"Electronics?" Hilfi blinked, listening to this unfamiliar word.

"Well, we call the thing that causes lightning an electron, because one side has more electrons and the other side has fewer electrons. When electrons flow from the side with more electrons to the side with fewer electrons, lightning is produced." Rudius reinterpreted lightning using the electron.

"I know that lightning is caused by the flow of electrons, but why does lightning occur?"

"Wind pressure difference creates wind, which is easy to understand because the wind moves. But why is the movement of electrons so earth-shattering?" Hilfi first sorted out her thoughts with a puzzled look, then looked at Rudeus and raised her hands to make a gesture that sounded "huge".

Rudius tilted his head, thinking that he had actually already given the answer—because electrons are difficult to move.

However, Hilfi has no concept of "electricity." Electricity is not an energy source in the jobless world; it is a technology of a more advanced civilization.

Since there is no electricity, there is no concept of "resistance" or "insulation".

"Sit down first." Rudeus used earth magic to make two stools and placed them on the wet grassland.

After the two were seated, Rudeus said, "Sylphie, do you remember how we increased the power of our Explosion magic?"

"Increase power?"

"It's like sealing explosion magic within earth magic, right?"

The release of the Explosion spell requires the mage to actively compress magical energy. To allow Sylphie to intuitively understand this phenomenon, Rudeus created an earthen ball and had Sylphie infuse it with magical energy.

It's like blowing up a balloon until it bursts.

Under the infusion of Silphi's magic, the earthen ball naturally exploded.

"Yes, that's the feeling of the final explosion. More and more electrons appeared, and then finally they started moving."

Therefore, the movement of electrons, just like the movement of air, can trigger lightning.

This is because electrons move extremely fast.

Rudeus gestures with his hands to the left and right, conveying a sense of accumulating energy, then slowly brings his palms together to represent wind, and finally claps his hands quickly to represent lightning.

With a puzzled look, Hilfi asked, "But Rudy, what exactly is lightning?"

"Lightning, oh lightning—" Rudeus lowered his hands and scratched his chin.

Even if you actually see lightning, you wouldn't know what it is.

"Yes, that was the time it was used in combination with earth magic."

When faced with something incomprehensible, one can only feel that the might of Heaven is unfathomable.

Rudius used earth magic again to create a small table and placed it between the two of them.

It's called a table, but it's only about one square meter in size.

Rudeus stretched out his right hand, palm down, as if holding a puppet on strings, and said with a smug smile, "Sylphie, watch closely, this is lightning."

As soon as he finished speaking, a glimmer of light appeared out of thin air beneath Rudius's palm.

Upon seeing this, Hilfi unconsciously leaned forward to take a closer look.

After the light appeared, it did not stay there, but instead emitted clearly visible luminous ribbons like slime mold, which touched the tabletop piece by piece.

Rudius's forces seem to be growing from a glowing root system, with its branches spreading out more and more.

As the leading filament approached the tabletop, all the luminous ribbons vanished instantly, leaving only the leading filament emitting an extremely thin and bright light.

It then flashed slightly before slowly disappearing from the visual afterimage.

"Wow~!" Sylphie exclaimed, her mouth agape. "Did it just flash?"

"That's right."

The miniature lightning bolts released by Rudius actually lasted only about a second from start to finish.

Although it is still very fast, it is thousands or even tens of thousands of times slower than real lightning, making lightning something that can be observed with the naked eye.

He used magic to generate electrons and then suppressed and amplified their flow, simulating lightning in his hands.

Do you think he knows what an electron is?

No, he didn't know.

He simply found the electron.

Since the Water King-level magic [Lightning] can be guided, it means that electrons can also be guided.

Rudeus didn't know what it felt like for other mages to unleash lightning, but he could connect his past life's concepts with his current feelings.

It's like going to a shopping mall with a detailed instruction manual to find a product.

All you need to do is find that feeling of "grabbing" unfamiliar matter when releasing a [hauric cumulonimbus], and verify that its properties are electrons.

Rudius had also worried about being electrocuted, but how to put it...

In a world without jobs, energy is conserved, so electrical charge is naturally conserved as well.

It's like casting fire magic without worrying about getting frostbite.

Whether it's heat or electrons, they are all transformed by magic.

Once you understand the principles of lightning, you won't need to worry about hurting yourself.

Of course, if you don't understand this, you might accidentally extract your own electrons to launch lightning, turning yourself into a human bomb, or be killed by the lightning that immediately retaliates.

"Rudy! How did you do that? Can I learn? Teach me quickly!" Hilfi stood up and excitedly grabbed Rudy's wrist.

"Hehe, Hilfi is already a Water Saint-level mage, of course she can learn it." Rudeus said confidently, looking into Hilfi's bright eyes.

"Hmm... let me think about it."

Rudeus looked up at the dark clouds in the sky and suddenly recalled the days when he and Sylphie burned wheat together.

"Silphie, do you remember when you rubbed the amber with fur?"

"Yes, I remember."

Rudius raised his hand and pointed to the clouds in the sky, saying, "Amber and fur are like water droplets in the clouds. They keep rubbing against each other. Water and electrons are like wheat and wheat husks. If we rub them with our hands, the wheat husks will be rubbed off."

Where does the wheat bran that's rubbed off go?

Sylphie looked in the direction Rudeus was pointing, thought for a moment, and replied, "It'll fall to the ground?"

"That's right. So above the clouds are many wheat grains (positive charge), while below the clouds are many wheat grains and bran, and the bran is electrons."

Although they were rubbed apart, they still wanted to become whole wheat again.

So he reached out and groped around in the air (step leader).

The wheat grains on the other side were also groping around in the air (connecting the leader), but because they were too heavy, they were moving very slowly.

When a wheat grain and its husk come into contact with each other, they revert to a whole wheat grain, which is how lightning is created.

Rudius continued to gesture with his hands, one pretending to be a grain of wheat and the other a wheat husk.

As the explanation was completed, their hands clasped together.

"Why don't the wheat husks at the bottom of the clouds go find the wheat grains at the top of the clouds?" Hilfi asked.

"Yes, of course it will look for the wheat grains on the cloud top, but they are all hiding in the clouds. The lightning in the clouds is them searching for each other inside the clouds. The one that hits the ground is the one we see."

After the explanation, Rudius realized that it seemed that lightning in the clouds was called "thunder," while only lightning connected to the ground was called "lightning."

Even after arriving in another world, this hasn't changed.

These two closely related phenomena are clearly considered to require two different terms to describe.

On a cultural level, the interpretation and understanding of written characters do not consider them to be the same thing.

"But lightning strikes the ground, so doesn't that mean all the wheat husks will end up on the ground?" Hilfi asked, puzzled. "What about the wheat grains still in the clouds?"

Rudeus had taught Sylphie the concept of conservation of energy, so it was understandable that she would have this question.

"Hilfi, where do you think lightning goes from and where it goes?" Rudeus countered.

"From the bottom of the clouds to the ground?" Hilfi replied uncertainly.

"Yes, that's how ordinary lightning works, but there's also lightning that travels from the top of the clouds to the ground. Thunder itself is lightning that occurs inside the clouds."

After speaking, Rudeus paused, allowing Sylphie time to process what he had said.

"oh."

Upon hearing Silphie's voice, Rudius continued, "So, actually only a small amount of wheat husks fell to the ground."

"So where did they go?"

"Hmm—so where did the wheat husks on the fur and amber go?"

Faced with Rudeus's question, Sylphie paused, then blurted out, "Oh right, where did they go?"

"Hehehe," Rudeus chuckled, looking at Sylphie's adorable expression. "Of course, I'll run away when you're not looking. But you can also touch your father's dagger and you'll see."

"Oh right! It's static electricity! So that's lightning too!" Sylphie suddenly realized, then complained to Rudeus, "Hmph, Rudeus, you're still trying to fool me!"

"Hahahaha." Rudeus laughed, then suddenly stretched out a finger and touched Sylphie's little hand.

A "snap" sounded between the two little hands.

"Whoa!" Sylvie exclaimed, "Rudy! You shocked me again!"

Seeing Sylphie's "grief-stricken" expression, Rudeus immediately feigned ignorance of what had just happened and asked, "What?"

"Ru~dy~!" Silphie drawled, puffing out her cheeks as she shouted, "You can't fool me anymore!"

Rudius blinked, then replied innocently, "What are you lying about?"

"Hmm~~"

Hilfi stood up and reached out to poke Rudeus.

He watched silently until he was about to be stabbed, when suddenly he was blasted away by the earth magic beneath his feet.

After a perfect backflip, Rudius, like an athlete, stretched his arms towards the sky and exclaimed, "Thump thump!"

"Ha ha ha ha----"
