Wizard: I brought the wrong system.

Chapter 336 Dream Bubble
"Most objects contain tiny particles called electrons. Normally, these electrons are at rest. If we compare them to calm pools of water, then lightning is a raging waterfall, and ordinary sparks and electric currents are streams and rivers."

No one knows whether items like magic crystals and magic stones contain electrons, which is why Yaro said most items do.

Otherwise, substances normally composed of atoms would certainly contain electrons.

"Under the influence of gravity, water flows from high to low. To create an electric current, a force must be applied to the electrons so that they can flow and form an electric current."

Yarrow didn't explain much about chemical power generation; otherwise, he would have had to describe what 'chemistry' is, and explain what losing and gaining electrons means, in order to roughly explain the principle of chemical power generation.

"A magnetic field is like a pair of 'hands' that can touch electrons. A generator is a fixed magnetic field, like a thin rod that can touch electrons, allowing people to move the electrons in objects..."

Even after reading it many times, Heryl still couldn't help but lose herself in thought.

Electrons, electric current, magnetic field... unfamiliar words.

Ponds, streams, hands... ordinary things we see every day.

In this way, they were compared and connected.

Not only did it make Heri clearly understand what 'electricity' really was, but it also opened a door to a new world for her.

Behind the gate, everything was mysterious and silent.

It was so novel.

Excitement surged within Heri. Like a newborn baby nestled in her father's warm embrace, she curiously surveyed this brand-new world.

"Lord Yaro..."

Heryl took a deep breath, calming herself down.

After having a general overview of the "new world," she was able to understand a bit more about the generator structure diagram that Yaro had drawn for her.

"First, there's the fine copper wire."

Copper wire has excellent ductility, and by using the same method as steel wire, it is easy to make a large quantity of copper wire, and it can even be made finer.

"Then there's the resin."

The weather had been very cold for the past few months, so there wasn't much resin to collect. That's why, when Yaro was making the glider, he didn't use the clear, bright resin, but instead left it for little Heri to use as insulation.

Most tree resins are excellent insulating materials. In Aro's previous life, many household appliances, wires, sockets, and plugs were covered with tree resin.

"Heat the resin, soak and wash the fine copper wire in it, so that the surface of the fine copper wire is coated with a thin layer of resin."

The copper wires inside the motor are not bare copper wires; they have a thin layer of insulating enamel coating on their surface, commonly known as enameled wire.

Without this insulating layer, the current generated by the magnetic field cutting would only flow within these copper rings, and the kinetic energy of the electrons would be converted into heat and light energy and released directly, causing a short circuit in the motor and preventing the generation of current.

"Wrap the copper wire, which has been dyed with resin, around in circles, fix the magnet, and install the bearing..."

The laboratory contained many semi-finished parts and a variety of tools for making items, which made the process of making items by Little Heri go very smoothly.

As night deepened, little Heri finally finished assembling the makeshift generator.

"Then... let's give it a try?"

Little Heryl was thrilled.

"Yes, now that an item has been made, how can we not try it out?"

Thinking this, little Heryl reached for the rocker arm bearing.

Squeak, squeak...

The iron rocker arm swayed incessantly on the frame of the dead wood.

Bang, bang...

Two copper wires, which were not far apart, suddenly flashed with a string of tiny electric lights.

As if by coincidence, almost at the same time, a thunderclap suddenly rang out outside the house.

A faint white light appeared in the sky, like a white dragon slowly swimming across the dim night sky.

An invisible pressure enveloped the castle.

Some of the sleeping servants suddenly gasped uneasily, jolted awake from their slumber. In the dim corner, a moving shadow froze in place, then suddenly exploded into a ball of blood.

"Huh? What kind of technique is this?" A surprised and uncertain voice rang out from somewhere.

A damp, cool breeze caused the candlelight to flicker slightly.

Little Heri, engrossed in the faint electric arc, was completely unaware of her surroundings.

"This is an electric spark!"

Little Heri stared wide-eyed at the gap in the copper wire with curiosity.

She wasn't unfamiliar with electric sparks.

Following the method of generating electricity through friction, little Hery had already seen flashes of electric light.

But those flashes of light were too brief.

So brief that little Heri didn't even know if what she saw was lightning, or the last glimmer of light before it disappeared.

Now, she finally saw real 'electricity'.

Although... it was just a tiny arc of electricity.

Thunder rumbled outside, but little Heri showed no fear; all her attention was focused on the tiny arc of electricity.

"If a single arc of electricity is so beautiful, then... how amazing would a spark of electricity formed by the convergence of millions of arcs be?"

Little Heri glanced at the brass tag placed to the side, looking at the intense electric sparks depicted on it... and those firm, bright eyes.

A sense of accomplishment, of getting closer to her dream, of taking a crucial step toward it, filled her heart.

"That's not enough! A mere arc of electricity isn't enough!"

"Only with more and larger electric arcs can the scene depicted on the tag be created!"

"Is there any way to increase the arc size, or to store this arc like a reservoir?"

Yaro hadn't taught little Heri anything about batteries, so she had to figure it out herself until Yaro returned.

"Since copper can be used to create an electric arc, then... can copper be used for storage?"

"Make bold assumptions and verify them carefully" is a phrase that Yaro often uses, so little Heri is ready to give it a try.

Little Heri paused, and the flickering arc of electricity beside her disappeared.

"Let's try using the bronze tag that Lord Yaro gave us!"

"If the tag, which already has an electric spark pattern, were to have real electric sparks added, the scene would be absolutely beautiful!"

With that in mind, little Heri connected the two ends of the copper wire to the copper tag.

"Then let's get started!"

Little Heri took a deep breath and shook the rocker arm bearing beside her.

Clap!

A bolt of lightning actually bypassed the window and struck the brass tag!

Rumble...!
Thunder rumbled, and the bronze tag shone brightly.

Little Heryl was stunned.

Many images seemed to appear in her eyes.

Strange dolls, ordinary boys, many flat-faced girls floating in water, pristine white houses, towering skyscrapers...

And... a huge stone bridge that I feel is strangely familiar with!
Everything was like a dream, yet it was also real and tangible.

It's like...within reach.
