It's a strange money. Pen, Fun, Pavilion www.biquge.info', the old man who had just decided on the technique, repeatedly rubbed the coins in his hand. First he picked up five coins, and then he picked up copper coins.

I just touched five yuan, and I just thought it was very strange, thinking it was metal I had never seen. But now that I got this copper coin, I realized that something seemed wrong. Something is very wrong.

He took both the copper coin and the five coins, and kept groping, and the weirdness in his heart was even worse. Until somebody called him, 'Grandfather, grandfather, do you think that's okay?' ’

'Oh, what? Seeing that my grandfather had not listened to them at all, the questioner said again, "We just said that this is five coins, although we don't know what it is made of, but it can always be melted, and we want to melt this money directly, and make it thinner like we used to do in the past." ’

When we were just discussing what this unseen metal was, someone said, 'Just melt him, since the mold is not a problem, then it is better to melt the money in the same way, and make it thinner.' ’

However, if it is made thinner, it probably won't be able to be used as five coins, and the characteristics of this new metal are not easy to grasp, so what if it is difficult to melt? They were just arguing about this.

'Do it, I don't know if I don't try it.' The old man made a decision, "If you don't try it, you don't know the effect, so make it thinner, just make it thinner." In Yangtze, in some remote places, one is large and the other is not enough, it can still be used. ’

The old man made up his mind, and they began to do it, and then, out of suspicion just now, the old man simply melted it down as five coins and a new round of money.

Melt to nothing, which they cook. It's just that this metal is a bit weird. Or rather, the new money is weird, 'What is this?' Finally, the money from the two furnaces was melted, and they all let out a miserable scream.

It turned out that the furnace of copper coins actually melted iron and copper, no wonder it was so strange, from the beginning of the melting, it was very strange, different from the copper coins they were familiar with. Now I found out that the new money of the imperial court, the copper plate turned out to be copper-clad iron.

This is not a copper coin, but a layer of copper on the outside, and a copper skin and iron tire. This court is too unconscionable.

How the hell is this done? The old man was strange just now, and now that the mystery is revealed, he is not so angry, just strange.

'How do you make money?' This', the original financier of Datang, let out a miserable howl. Don't be upset, you have to be in the mood, we can take care of it. There is a group of people in Yangzhou, saying this in their hearts, and they also let out screams in their mouths.

'How to use this kind of copper coin?' I felt the same way, and what howled together was the new copper coins that were exchanged for the imperial court and sold in Yangzhou at the same time, and the coppersmiths also wailed.

They got used to taking copper coins to melt them, and then they used them to cast bronze objects, but now this road is broken. The court is so unconscionable, this new money is actually made of copper and iron, and there is just a layer of copper on the outside, and an iron tire on the inside.

'What about that new metal. After screaming and scolding, the old man asked, "What happened to the new metal?" He was in charge of staring at the other furnace, his face was ugly, "Only iron remains." ''What. The old man ran to another furnace, only to see that under the furnace, there was only cooled iron, yes, iron.

'No matter how you look at the stove, you can't do a little thing. A middle-aged man spoke, he is regarded as the uncle of the furnace watcher, and he has always been at odds with the father of the furnace watcher, and now he is immediately in the ground.

God knows what's going on, how can this kind of thing be wrong, the only thing is that we don't understand the properties of this new metal. His father immediately stood up and spoke for his son.

'Do any of you know what it is?' Just when the two were at a stalemate, ready to disagree at any time and start a war, the old man spoke.

, everyone put aside the dispute for the time being, and stepped forward to watch. I saw a white powder in the old man's hand, and after looking at it for a long time, no one saw anything.

'This thing must be that new metal.' 'Go, have you ever seen metal like this?' I think he's mixed with molten iron. ''It's clearly gone, and your son is not strictly guarded.'' After looking at it for a while, I didn't see what it was, and then we started arguing again.

This thing should be a secret of the imperial court. It's just what the hell is this. The old man ignored them, just looking at the white powder in his hand.

Why didn't it flow out of the hole under the furnace, like other metals, he didn't know how much iron and copper he had melted since he was a child, so he had never seen such a strange metal. No wonder the imperial court dared to issue five coins, this strange characteristic of metal doomed them to be unable to imitate. Only the old man was sure that it was new metal, but it was too strange at this time.

This court is so unconscionable. In Datang, in many places, a similar wail was issued. 'Why, it looks like my ears are a little itchy. Li Chen plucked out his ears, he didn't know that in a distant place, there was a group of people who did their best for Datang and contributed to Datang's economy, and they were scolding him for having no conscience. He was visiting the elementary school.

At present, there are only two classes in this primary school. Regardless of age, depending on your knowledge, the literate and the illiterate. Those who are illiterate are still in small classes, and those who are literate are in large classes. It's like a nursery school or a kindergarten.

But this is also something that can't be helped, although Li Chen said that it is divided into grades, but in these eras, enlightenment education cannot satisfy Li Chen, and even education at a younger age cannot satisfy Li Chen.

'Sir, why is this so?' A few children in front of the teacher's desk were microscopic, raising their hands to ask Li Kai, who was quite polite, but this was a whiplash. The whip is a rattan, this kind of thing, it hurts to smoke people. But its light and thin appearance is destined to be just a pain. Of course, if you are ruthless, you have to smoke it to death, and it is also possible to smoke a skin and open the flesh.

This is unlikely to happen, though. As soon as Li Chen spoke, this whip is a lesson, not a tool for the teacher to use the students to get angry. No matter what happens on the spot, whipping needs to be done afterwards. Or substitutions.

Second, many of these children are relatives of the emperor, not that they can't be smoked, but they are really ruthless, and they can't stand it. Smoke those don't get it, and then the royal relatives don't touch any of them? Teachers in this era are not so tasteless.

Of course, when it is time to smoke, he will never be soft, because this whip, but the "Shang Fang Treasure Whip", is a royal gift. Li Chen gave the teacher to teach, and with this pump, on behalf of the emperor, he had no right to stop him.

There is such a "Shang Fang Treasure Whip" because Zheng went to see how his grandson went to elementary school. As a result, Li Yan took the lead in making trouble, did not go to class, and was whipped by the teacher.

This was repaid, and Zheng Shi lost his temper on the spot, protected her grandson, and said, whoever dares to beat my grandson will kill her first. It was so troublesome that Li Chen left the deliberations of Yanying Hall and came in person. This is the second time since the official opening of the primary school. As a parent, this is the first time to come.

He persuaded him with affection and reasoned with reason. In the end, with Wei Zheng's words of how to return to Tang Taizong back then, he beat Yao and Shun, and persuaded Zheng to go if he didn't beat him, and then he gave this "Shang Fang Treasure Whip" to teach him a lesson, and he dared to stop it.

Today he came to the primary school for the third time, and this time he came quietly, just to see how the quality of teaching is. This small school opened very quickly. The classrooms are directly converted from a palace, and the desks, chairs, books, and teaching materials are all ready-made. He opened nursery schools in Chang'an and Yangzhou, and attached primary schools to obtain teaching materials.

The reason why the teacher is a problem is that he can not be satisfied with this traditional education, and he only distinguishes between large and small classes, and distinguishes between literacy and illiteracy The reason is that the traditional enlightenment education is to teach some literacy, at most it is to memorize ninety-nine multiplication.

Do you still remember that Li Chen once worked as an enlightenment teacher for a while? What did you learn at that time? 1,000-word essay, and first aid article, as well as the twenty-five words, literacy and practice, the short essay at the beginning of "Shangda". Plus a ninety-nine multiplication formula memorized backwards from behind. That's all.

Of course, this can't satisfy Li Chen's thoughts. He had already been in a small school outside, and set up a course of physics, arithmetic, astronomy, and so on, with little content, mainly to let them have some common sense and learn something that Li Chen thought was trying to get.

On the other hand, it also arouses their interest, God knows that they will be interested in which part, anyway, teach more, learn more, there will always be someone who is interested, as long as he is on the right path in the future, he will be satisfied, and he will not expect that each of them will be a pillar of the country.

It's a hand-cranked generator, and when you shake this handle, it generates electricity, yes, it's the kind of lightning in the sky, but it's much weaker. Electricity is generated, and when it flows through wires, a magnetic field is generated. The magnetic field is not visible, but we can use iron filings to represent what the magnetic field looks like. ’

In class, it is up to gundam, because there are not enough teachers, so many of them, who are classified as researchers by Li Chen, also have to come out to class. There is a small school outside, so it can be regarded as their disciple. At that time, several of those children were teachers.

To be precise, you can teach people. It's like the one who loved to ask questions, and the questions were strong. For Gewu, I'm more interested in Ah Mao.,Now it's also a teacher.,Teaching those who are just getting started.,No problem.。

Gundam shook the thick machine with his hand, looked at the children, and was surprised to hear that this was lightning in the sky. Lightning in the sky is just such a thing, the difference between strength and weakness.

It's not just lightning, they're now starting to use it. That kind of iron tire copper skin gets money, how can you get it? It's electrified. It is more accurate to say that it is called electroplating.

These children were just curious, and when he saw that electricity was such a thing, he had a feeling that the sky was falling. It seems that there is a lot less fear of God.

Later, when he discovered that electricity could be used for electroplating and could drive the engine in turn, he began to have a greater awe of the sky. It turns out that there are many wonderful phenomena in this world, waiting for people to discover, and find that lightning in the sky can also be generated by manpower, what's the big deal. Why this can generate electricity, he didn't think about it. Why is there a magnetic field? Why are there iron plates and copper plates, and if you put bile water, you can plate iron with copper? Too much too much why. can't help but make people re-awe of this day.

Gundam was a little distracted, causing him not to see Li Chen. Li Chen looked at the teaching situation of the two classes a little, and left without interfering with the class. Then in the Yeonying Palace, he summoned Suleiman. (To be continued.) )
