"Hahahaha, Potter!

In the face of this 'fellow friend', Potter also found it difficult to calm himself completely, and he said irritably: "Raditz, this is the seventeenth time you have said this! Look at your students, they are much calmer than you!"

"That's because they don't understand the greatness of this invention yet!"

Hearing Potter's words, Raditz immediately blew his beard and glared, and he slapped the table and shouted, "Do you know how great this invention is? You mages are very powerful, and with this, we ordinary people can do things beyond the limits of our bodies! Haven't you been to see it anywhere else? Foundry, and, and, ...... Other places - haven't you been to see them?"

"Oh......"

Potter slapped his head and groaned helplessly, "I know, I know it...... I made this thing with you, so Raditz, can you be quiet for a while? The head maid is coming in a moment, for the sake of our future research funds, can you be quiet for a while?"

"Ahh............h

The tutors are quiet, how dare the students not be quiet?

Seeing that the surrounding students didn't dare to talk to each other, Potter sighed helplessly: "It's okay, I'm talking about Raditz, as long as you don't talk too loudly." I'm sure you've gained a lot now, and it would be nice if you could exchange experiences and consolidate your knowledge with each other. ”

Raditz glared again at Potter's words, but this time he kept his mouth shut, it was clear that he knew what kind of virtue he was.

Porter's words relieved the students, and the students in the lab began to whisper their insights.

Potter and Raditz couldn't believe that the two of them were strangers who had nothing to do with each other two months ago, but in the two months of arguing and researching, they had an inexplicable tacit understanding, and it wasn't just them, but even their students had become like this.

Potter was a mage and Raditz was a scholar, they were both very old, and they had been hired here a few months ago because of financial problems, but they could now proudly say that it was the clearest decision they had ever made in their lives.

'Like-minded' is not enough to describe their relationship, but in the 'magical' language that the head maid proclaimed, there is one word that can describe their relationship, and that is 'like-minded' – 'like-minded'.

They were also interested in that language, so they learned a little bit and it really got them a lot.

Because it was a very mature language, many words were difficult to explain in the existing lingua franca, and only the relatively old and mature languages of dragons, elves, and giants could be translated, so they knew from the beginning that the language and script were not invented by her.

As a mage, Potter knew about the existence of 'electromagnetism' from the beginning, because it was also a very common tactic in actual combat, used to 'disarm' the weapons of warriors, or to block them for a period of time, often to save his own life.

But even if they knew about 'electricity generates electricity', they mages have never considered the issue of 'magnetism generating electricity'.

Even if they considered it, they didn't have the tools to observe the electromagnetic induction that was created by cutting the 'magnetic lines'.

Because it is difficult to observe, even if the 'result' is tested by coincidence, people cannot detect it, which leads to the fact that no one has succeeded in summarizing the 'electromagnetic induction' so far.

However, this statement is a bit too absolute, since the expulsion of the Arcane Empire, the connection between the major mage organizations has become much less, and even now, there is very little communication between mage organizations that are not from the same country, and Potter is not very sure whether the 'Cloud City', which represents the highest magic technology in the world, has a similar theory for a long time.

This theory was told to them by the head maid, and at that time, they also did an experiment, and it was also because of this experiment that they observed the existence of 'magnetic electricity', which means that there is indeed a thing called 'magnetic field' in their world.

The head maid had already observed this phenomenon and confidently conducted an experiment in front of them, because the current was so weak that they would not have been able to observe it if it weren't for the observation spells in the laboratory at that time.

Not to mention Raditz, an ordinary person, even Potter himself may not be able to notice.

It all happened two months ago, and now they can even use this 'electromagnetic induction' to invent a hand-cranked generator that can create a steady current.

This is what Raditz calls a 'great invention', and Potter, as a mage, also considers it a 'great invention of epochs'.

It's not very easy to use now, and it can be said that it's very weak, but if some improvements are made and the power of water is used to 'generate electricity', it may be that the 'era of ordinary people' may really come.

If that could be done, the street lights might not need to use the power of the elemental pool at all, and the quota of the giant elemental pool in the factory area could be used for other things.

Yes, Potter immediately thought of 'street lights'!

As a mage who had studied in Greenland, Potter had always missed the magic street lamps that dotted all the neighborhoods in Greenland, even though there was a street lamp on the main road of Winder City thirty feet apart, but there were still no street lights on other streets except the main road, and it was all lit by the light from the shops, and if there were no shops, they had to rely on natural light.

The transmission of electric current is not difficult, but the problem is that even the 'hand-cranked generator' in front of us is just a prototype, and it will take a long time to develop a hydroelectric generator.

"Maid Chief, please come in ......"

The door to the lab was pushed open, and both Raditz and Potter heard the commotion on the other side of the door, and hurriedly looked up and quickly stood up.

"Oh, Lord Maid, here you are. Raditz rubbed his hands stiffly, and Potter glanced at him with disdain, obviously he was so arrogant just now.

Although Potter also knew that Raditz might have done it for the sake of new knowledge.

However, in the face of this head maid, Potter couldn't help but become a little nervous, after all, their research funds have always been directly allocated by this head maid, and the financial department below can't manage them at all.

"Don't be so nervous, I'm just here to check the 'generator'. ”

The maid thought for a moment, "Actually, there's another thing, but we'll talk about that later, let's take a look at the generator first." ”

At this time, Potter also noticed the two little girls behind Serena, as well as the box in their hands.

At first glance, it was clear that the 'other thing' that the head maid said might have something to do with the contents of those two boxes.

They are all researchers who don't think much more than that, and after hearing the head maid say this, Raditz excitedly let go of her body, pointed to the hand-cranked generator behind her and said, "Look, Lord maid, this is the prototype we made!"

Edith and Anna looked at it curiously, then lowered their heads and looked at the box in their hands, and suddenly their hearts were a little clear.

The 'generator' in front of them was very rudimentary, and even in the eyes of Edith and Anna, it was simply a random patchwork of simple things, and there was no aesthetic 'weird thing'.

The maid took a cursory look at it, then turned her head and asked, "What is the actual effect?"

"Uh, this ......" Raditz and Potter looked at each other with some embarrassment.

"If you rotate at a constant speed, you can provide 'some' steady current, but there is still a bit of a difference from when it was originally conceived...... Raditz finally said with a slurring of words, and Potter rubbed his fingers uneasily under the cover of his wide robe.

"So, do you want to give it a try?"

Raditz and Potter were stunned for a moment, and then quickly reacted, it turned out that the maid was going to see the test results!

But to their surprise, Serena took out two 'glasswares' from Edith and Anna's hands...... No, it should not be said to be a 'glass product', and there is a layer of metal wrapped around the ends of the columnar glass.

"Actually, I've been waiting for this moment for a long time!"

The maid herself wound the copper wires connected to the generator around the ends of the 'incandescent lamp', and with anticipation on her face, she slowly turned the generator.

Looking at the flashing light in the glass, she inexplicably felt like crying.

Serena turned her head and sobbed and said, "Look, this is the dawn of a new era, this is the 'first light'!"

However, not many people paid attention to her words.

All of them!

Everyone was so captivated by the light from the light bulb that they couldn't take their eyes off it......

'First Light'!

"Old Fellow......"

Potter suddenly heard Raditz calling to himself, and he turned his head away, "What's wrong?" asked softly.

Raditz suddenly hugged Potter—

"We made it!!"
