Duke of Grief

　　 "Hahahaha, Potter! We succeeded!"

Faced with this'common friend', Porter also had a hard time calming himself down. He said anxiously: "Latiz, this is the 17th 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!"

After hearing Potter’s words, Latiz immediately glared with his beard. He clapped the table and shouted, “Do you know how great this invention is? You masters are very powerful. With this, ordinary people like us can also Do something beyond our physical limits! Haven't you seen it elsewhere? Foundry, and...and other places-haven't you seen it?"

"Oh……"

Potter slapped his head and moaned helplessly: "I know, I know... I made this with you, how come I don't know? So Latiz, can I be quiet for a while? Maid Changyi The meeting is coming. Can you be quiet for a while for future research funding?"

　　 "Ah, oh..." Latiz rubbed some painful palms and accused: "For funding, for funding..."

　　The tutors are quiet. How dare students not be quiet?

Seeing that the students around didn't dare to talk to each other, Potter sighed helplessly: "It's okay, I'm talking about Latiz, as long as you don't talk too loudly. I believe you must have a lot of gain now, if It's also good to be able to exchange experiences and consolidate knowledge with each other."

　　 After hearing Potter’s words, Latitz stared again, but this time he closed his mouth. Obviously, he himself knew what virtue he was.

　　 Potter's words made the students relieved, and then the students in the laboratory began to whisper the exchanges of their understanding.

Porter and Latiz could not believe that the two of them were strangers who had no relationship two months ago. As a result, in the two months of noisy and research, they all had an inexplicable tacit understanding, and It’s not just them, even their students.

Porter is a mage, and Latiz is a scholar. They are very old. They were hired here a few months ago because of financial problems, but they can now be proud to say that this is what they have done in their lifetime. The clearest decision ever made.

　　 ‘Tonghao’ is not enough to describe their relationship, but in the ‘magic’ language announced by the maidservant, there is a word that can describe the relationship between them.

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

Because it is a very mature language, many vocabulary is difficult to explain with the existing common language. Only the relatively old and mature languages ​​such as Dragon, Elven and Giant can be translated, so They knew from the beginning that the language and writing were not invented by her.

As a mage, Potter knew the existence of'electro-magnetism' from the beginning, because this is also a very common tactic in actual combat. It is used to'disarm' the soldiers' weapons or block them for a period of time. You can save your life.

　　But even if they knew ‘electromagnetism’, their masters had never considered the issue of ‘magnetism’.

　　Even considering, they have no tools for observing the electromagnetic induction generated by cutting the'magnetic induction line'.

　　Because it is difficult to observe, even if the ‘result’ was tested between coincidences, people could not detect it. This has led to no one who has successfully summarized the ‘electromagnetic induction’ so far.

However, this statement is a bit too absolute. Since the Arcane Empire was expelled, the links between the major mage organizations have become much less. Even now, there is little communication between the mage organizations in the same country. Porter didn't quite understand whether the "Cloud City", which represents the world's highest magical technology, already had a similar theory.

This theory was told by the maidservant, and at the time, they also conducted an experiment, also because of this experiment, they observed that the "magnetoelectricity" exists, that is to say, their world does exist There is something called'magnetic field'.

The maidservant had observed this phenomenon for a long time, and confidently conducted an experiment in front of them, because the current was too weak. If it was not the observation spells in the laboratory at that time, they really could not observe the stock. Current.

　　 Not to mention the ordinary person Latiz, even Potter himself may not notice.

　　All this happened two months ago, and now they can even use this'electromagnetic induction' to invent a hand-held generator that can produce a stable current.

　　This is the'great invention' in Latiz's mouth. Potter, as a mage, also thinks it is a'epoch-making great invention'.

　　Although it is not very easy to use now, it can be said that it is very tasteless. However, if some improvements are made and the power of water flow is used to generate electricity, the age of ordinary people may actually come.

　　If you can really do that, maybe the street lamp does not need the power of the element pool at all, and the quota of the huge element pool in the factory area can be used for other things.

　　Yes, Potter thought of'street lights' the first time!

As a mage who had studied in Greenland, Porter has always missed the magical street lights of Green Street all over the block. Even today’s Winder City main road is also set up with a street light 30 feet apart, but in addition to the main road Beyond the Tao, there are still no street lights on other streets, all relying on the lighting from the shops. If there is no shop, you can only rely on natural light.

　　 The transmission of current is actually not difficult, but the problem is that even the ‘hand-cranked generator’ in front of you is just a prototype. It takes a long time to develop a hydroelectric generator.

　　 Click!

　　 "Maid maid, please come in..."

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

　　 "Oh, grown-up maid, you are here." Latiz rubbed his hands sternly, and Potter glanced at him sideways with contempt, obviously just so arrogant just now.

　　Although Potter knew that Latiz might have done so for new knowledge.

　　 But in the face of the maidservant, Potter couldn't help but get a little nervous. After all, their research funding has always been directly allocated by the maidservant, and the financial department below can't manage them.

　　 "Don't be so nervous, I'll just check the "Generator"."

　　The maid thought for a while, "In fact, there is another thing, but I will talk about it later, let's take a look at the generator first."

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

　　As soon as I looked at it, the ‘other thing’ that the maidservant said might be related to the things in those two boxes.

Researchers who have nothing more than thought, after hearing the words of the maidservant, Latiz excitement and turned away, pointing to the hand crank generator behind him, said: "Look, maidservant, this is what we made The prototype that came out!"

　　Etis and Anna glanced curiously, then lowered their heads to look at the box in her hand, and suddenly there was something clear in her heart.

The'generator' in front of me is very rudimentary, even in the eyes of Edith and Anna, this is simply some random things that are free to put together and do not have any sense of beauty.'www.wuxiaspot.com~ The maid takes a rough look After a few glances, he turned around and asked, "How is the actual effect?"

　　 "Uh, this..." Latiz and Potter glanced at each other awkwardly.

"If it rotates at a constant speed, it will be able to provide "some" stable current, but there are still some differences from when it was originally conceived..." Finally, Latiz said in a huff, Potter under the cover of a wide robe, Anxiously rubbed his fingers.

　　 "So, do you want to try it?"

　　 Latiz and Potter froze for a moment, and then quickly reacted. It turned out that the maid grew up to see the test results!

But to their surprise, Serena took out two'glass products' from the hands of Edith and Anna... No, it should not be said to be'glass products'. In the cylindrical glass, two There is also a layer of metal wrapped around the end.

　　 "Actually I have been waiting for this moment for a long time!"

　　 The maid wound the copper wire connecting the generator to both ends of the ‘incandescent lamp’, and with anticipation on her face, she slowly turned the generator.

　　 looked at the gleaming light in the glass, but she inexplicably felt like crying.

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

　　However, not many people noticed her words.

　　 Everyone!

　　 Everyone was attracted by the light in the light bulb, and they couldn't move their eyes...

　　 ‘First light’!

"Old boy……"

　　 Potter suddenly heard Latiz calling himself. He turned his head, "What's wrong?" he asked softly.

　　 Latiz suddenly hugged Potter--

　　 "We are successful!!!"
