Great Tang princess

Chapter 583 Foreigners

According to ancient legends, when Cangjie created characters, ghosts and gods cried out because humans learned the power of gods.

But today, at this very moment, in front of the Academy of Engineering and all the military officers, human beings once again stole the power of the gods.

The two ends of thread in Li Yuechen's hands made "sizzling" sounds as she fiddled and collided with each other back and forth, and at the same time shone with dazzling light.

This light was extremely short-lived, but it was extremely bright. Many people couldn't help but close their eyes in the night. Even when they looked elsewhere, there was still a clear light spot shining in the field of vision in front of them.

After being surprised by each other for more than ten seconds, they gradually realized that they couldn't help but took two steps forward, surrounded Li Yuechen, and looked down at the two wires in her hand at the same time.

"A miracle, a true miracle!"

An academician couldn't help but yelled.

The other people have similar expressions. The ancients were in awe of the power of nature like lightning, but now this kind of power has appeared in the hands of everyone, and the degree of surprise can be imagined.

The most important thing is that the things inside are all made by their own hands. They are very clear about the production process, but no one could have imagined it before.

Compared to the astonishment of the craftsmen, warriors like Geng Yunqiang and Wang Wuqiong were much calmer. Although it was indeed a miracle, what came from the hands of the princess must not be mortal.

From their point of view, since the princess even made a flying machine, it didn't seem unacceptable to invent a sky thunder or something.

Compared with these, Geng Yunqiang was more curious about another question.

"Your Highness, can this thunderbolt be used on the battlefield?" He almost couldn't wait to ask.

"It will definitely work in the future, but I'm afraid it won't work at the moment." Li Yuechen shook his head and roughly explained, "This thing is not a weapon, it's just a kind of energy..."

Although it was a little unclear, the people around still understood. For now, this thing is used to stimulate certain machines to use.

Wang Wuqiong asked curiously: "Then, what exactly is it, Your Highness?"

"This, you will understand after a while." Li Yuechen smiled, "Today is just to let you understand the function and principle of this object. The specific function will be gradually developed in the future."

The people around were so surprised by this primitive generator that they couldn't speak. Even after the disbandment, they were still thinking about Her Royal Highness's explanation just now.

Li Yuechen, who returned to the room, was lying on the bed, staring at the ceiling in a daze.

The success of the generator is a good thing, but the problem is that I don't know anything about batteries, and the generated electricity cannot be stored, which is a very troublesome place.

It seems that the generator should be taught to these children in schools as soon as possible. As for the battery, they can only study it slowly.

Anyway, the industrial revolution has not yet come, so there is no rush for this thing. Even if it takes five hundred years to make this battery, it will be profitable.

The emergence of airships and generators has made this country a thousand years ahead of the world. It is time to slow down and tidy up from the inside.

……

The next day, Li Yuechen sat in the office and began to write new textbooks, at least to write out all the knowledge about electricity.

But as I was writing, I discovered a huge problem. I myself have only a half-knowledge, and there is no system at all. How can I teach them?
After writing for a whole afternoon, I picked it up and looked at it myself. I felt that it was just a hammer here and a stick here. How useful can this kind of knowledge be taught to them?
But it doesn't matter if you don't teach it, otherwise, it will just leave such a thing behind, and there is no way for it to continue to develop.

So broken knowledge doesn't matter, as long as it can stay, I believe that one day, someone will be able to complete it.

After figuring this out, there will be no problems. Li Yuechen continued to write hard, trying to write all the knowledge he knew in this area as soon as possible.

If it's bad, at least they now know that it's enough to turn a magnet in the middle of the coil to generate electricity.

In the next few days, in addition to writing the teaching materials, Li Yuechen further improved the design of the fan, and then called the people from the Engineering Academy to discuss the production issue.

It is impossible for generators to use human power to generate electricity forever. Now that the bearings can be made, it is indeed possible to consider the issue of wind power generation next.

In the office, Wang Wuqiong was asked to pour them a cup of tea. Li Yuechen stood in front of the board and explained while drawing: "First of all, we need to make a big fan like this and put it on the top of the mountain. Come on, as long as the sea breeze blows, it will drive the fan and rotate the magnet, and it will generate electricity continuously..."

Now there are bearings and gears, and the preconditions for making fans have been met. It is not difficult to make this thing at all.

In addition to the fan, the Engineering Academy also had another task, which was to make a telegraph. What Li Yuechen thought of was to install a pencil and a note on the board through metal parts.

When operating on the other side, keep pressing the transmitter, and the pencil on this side will click on the paper to form a pattern of dots and bars.

The codebook has already been written, so that the communication revolution can be fully started.

It is not realistic to want to engage in radio in this era, but wired telegraphy is completely feasible, and the preconditions are also met. The next step is the formal experiment.

Among other things, as long as the experiment here is successful, I will go back to Dongdu immediately and ask my mother to order the construction of a cable telegraph line from Dongdu to Chang'an.

Thinking of the possible career in the future, Li Yuechen couldn't help but put a smile on the corner of his mouth. This way, the communication between the two places will be much more convenient in the future.

……

It was the end of July in a blink of an eye, and the children's summer vacation was over. They returned to Qingdao by airship and were ready to start classes.

Recently, the new textbook written by Li Yuechen has also been completed. It just so happens that the courses for this school year can catch up, and then let them learn new knowledge.

In order to arouse their interest, Li Yuechen also brought them to the warehouse of the Engineering Academy at night, allowing each of them to enjoy the thrill of sparking with a wire.

If it is put in the future, maybe this thing is quite boring. After all, taking apart a lighter can have a similar effect, but in this era, this novel experience makes these children so happy that they can't sleep.

Back at the dormitory at night, I was still discussing the appearance of the electric sparks crackling, and at the same time discussing what its final effect would be like.

On the first day of the second day of August, they were clamoring to play, but Li Yuechen asked them to study hard so that they could make bigger ones in the future.

After comforting the children, let them go to class quickly. In the first few days of school, they usually have maladaptive syndrome, and they need to be disciplined.

……

After sending the children to class, Li Yuechen passed by Yantian, planning to go to the engineering institute to see how the fan production was going.

The craftsmen said that the wood was too heavy, and wanted to use bamboo to make it. Li Yuechen never expressed his opinion on this aspect, and he listened to them, and he did what they said.

It doesn't matter if you are wrong, experiment, how can there be a one-time success?

However, as soon as they walked to the Yantian, they saw Junchen and Lu Xiaoqian waving at each other from behind, and then separated.

It stands to reason that in this era, the two should salute each other respectively, but the gesture of waving was also inspired by Li Yuechen.

Li Yuechen didn't want to read other people's gossip casually, not only felt embarrassed when bumping into him, so he walked out from behind the wall after Lai Junchen left.

"Your Highness?" Lu Xiaoqian seemed a little curious that she appeared here, but she immediately raised her hand to salute.

Not to mention, only after staying in the military academy for a while, this salute is extremely standard, with his chest raised and his head raised, and his demeanor is also very good.

"Ah..." Li Yuechen waved his hand, "What? Are you gone?"

Although I don't understand what this means, but I can probably guess it from the context, Lu Xiaoqian thought for a while: "Your Highness may have misunderstood, I never thought of having a private life with him."

"Ugh?"

Now Li Yuechen was a little suspicious: "Then at the beginning..."

Lu Xiaoqian replied: "At the beginning, I was the daughter of Lu's housekeeper, and I could see the end of my life at a glance, so I wanted to do things that I would not do in normal life..."

After listening to her explanation, Li Yuechen finally understood, did the co-author play with him just for excitement?Or that this girl is really brave, as a slave, she won't be afraid of being beaten to death by her master if she does such a thing?
Perhaps seeing the surprise on her face, Lu Xiaoqian smiled wryly: "Your Highness doesn't know something. In fact, I did have the idea of ​​suicide at the beginning. If I met Your Highness a few days later, maybe..."

Li Yuechen quickly interrupted her: "Okay, okay, I don't want to ask about the past, as long as I don't have the idea of ​​suicide at this moment."

"Don't worry, Your Highness, I am really happy in this life." Lu Xiaoqian smiled.

Hearing this answer, Li Yuechen was relieved, as long as there is no one, otherwise it would be too defenseless to spend so much money to train an officer to come out and commit suicide.

But since she could see it, Li Yuechen didn't want to say anything. After chatting for a few words, she went to the Engineering Academy to check the fan's progress.

With the ingenious hands of the craftsmen, the fan has also been made recently, and the rest is to install the bracket inside, and then put the power generation equipment in it.

In the next few days, the craftsmen gathered together to play all kinds of whimsy, and finally put the power generation equipment inside the fan after installing a simple bracket.

Then it is connected with the gear through the transmission rod, so that the motor can be driven to rotate while the fan rotates.

As it approached, the people from the engineering institute were busy again, carrying the fan to the seaside, let the sea breeze blow it, and see if it could move.

The final result is quite gratifying. Seeing the fans spinning rapidly on the beach, the artisans cheered in unison.

After pulling out the wire and touching it to confirm that there was electricity, Qi Qi breathed a sigh of relief. His Highness was finally not disappointed, and the task assigned was completed.

Li Yuechen couldn't help laughing, now that the experiment was successful, the experiment on the telegraph machine can begin next.

Considering that it is not clear how big the voltage is and how far it can be transmitted, the length is very important.

After careful consideration, Li Yuechen decided to set the length from his office to the engineering institute.

If this distance is calculated as a straight line, at least one hundred and fifty meters, if one motor can't even transmit this distance, then... only a few more can be added.

Li Yuechen led the people from the Engineering Academy non-stop to start planning the route. Considering that there is no rubber in this era, it is impossible to make wires erected in the sky like in the future, so the best way is to go directly underground.

Make a groove with cement and fill it into the ground, then put the painted wire into the ceramic tube and lay it there, cover it with a cover and fill it with soil, it should prevent things like mice and ants.

At that time, a sign will be erected, and it will say "National defense wires, digging is prohibited". If anyone makes trouble, they will have to compensate for the losses of the troops and have to send them in.

Speaking of this, I read a joke on the Internet before, saying that the foreman called the boss: "Boss, I accidentally dug..."

"If the water pipe is dug up, I will pay you how much money it has right away. If an ancient tomb is dug up, the work will be suspended for a few months..."

"Neither, I dug out a black leather pipe as thick as an arm..."

"Don't call me boss, I'm abroad, and the company sent you off just after getting off the plane."

After all, the joke is just a joke, but it is enough to explain the importance of national defense optical cables. With the development of science and technology in the future, this place will definitely develop into this way.

So Li Yuechen put up a sign here in advance to warn them, also to let people in the future have an idea, don't accidentally cause a big event, it will be too late.

While holding the map, I was discussing with the craftsmen to plan the route. It was already dusk when everything was done, and the golden glow was splashed on the ground, and the little golden light that appeared was still a bit dazzling.

"Okay, then follow this route to make cement tanks and ceramic pipes, and the copper wires must also follow..."

"Yes! But Your Highness, there is not so much copper in Qingdao at present, and we need to report to the logistics department of the Ministry of War..."

"Then go and report it. After finishing writing, just bring it to my palace for stamping."

Signatures are not popular these days. The official documents of the imperial court are all the big seals of various departments. Now the big seals of the Ministry of War are in Li Yuechen's hands. Only after the seals are stamped can they be regarded as official documents.

……

After finishing these things, taking advantage of the time before dinner, Li Yuechen planned to go for a walk.

At this time, a soldier suddenly came to report: "Your Highness, there are ships appearing on the sea."

Have a boat?Could it be that Liu Zihe came over?

Li Yuechen came to the coast with some doubts, but when he saw it, he found that it was a very backward ship, not like a domestic one.

Before the sun had completely set, she picked up the binoculars and took a closer look. When she saw the clothes and appearance of the people on board, she immediately had an answer in her heart.

It's the group of people who have a good life.
