Li Chen looked at the teaching situation of the two classes a little, didn't interfere much with the class, and left. Pen? Interesting? Pavilion wWw. ｂiquge。 info Then in the Yeonying Hall, he summoned Sulaiman.

How does the new money react? , the Euphoria. The new money is beautiful and good-looking, and the people are very popular. The reaction was intense. We have recycled old money with new money, and we have made good progress, and we have recovered tens of thousands of dollars. At this rate, plus the money recovered by the tax law, a profit of one million dollars can be made every year.

Li Chen was very satisfied when he heard this, but he didn't expect that just a new amount of money would make the imperial court an extra million dollars a year. There will be such results because he used the new method to make money.

There are several new methods of money that he adopted, first of all, hydraulic power to suppress money. Or do you have to make the mother money first, and then use the mother money to make the pattern. However, he switched to an iron model. Heat the iron plate to a certain temperature, which can be molded to the temperature, and then press it into shape.

These are two new technologies. Hydraulic compression, and cooling method. The cold hammering method, yes, those craftsmen did not live up to his expectations and completed the cold hammer armor. In one test, the cold armor was shocked by the heavenly man, and the mistake was the heavenly armor.

The curved and smooth armor can reduce the puncture wound, whether it is a sword, a gun, or a arrow, it is easy to slip away. Even if it is not slippery, the cold armor has to be strong, and it will not be lost to the mountain armor. This is the worst, and in other aspects, the effect of resisting slashes and slashing is even more astonishing, and Li Chen has already decided to produce on a large scale.

It's a long way off, let's talk about money. Hydraulic pressure makes it faster, better, and cheaper to produce money. Li Chen had already ordered that the money guards under the sky should be abolished immediately, and all the money would be sent to Chang'an, and after that, only Chang'an would have money supervisors.

However, this money-saving production capacity has far surpassed the total production capacity of Datang in the past. At present, the annual output can reach 500,000 yuan. Next year, there will be more, and the amount of money is expected to exceed 1.5 million. This is the amount of money that the Tang Dynasty has spent in the past ten years.

It's not that you can't shoot somewhere else, like the flying fox money supervisor who uses the bronze in the boat. It's just that, for the sake of technical secrecy, I can only focus on it for the time being.

There are two kinds of money that is being pressed out of the new flush. But it's all iron. Speaking of which, he really turned a new page in the history of China's currency minting. Basically, in all the dynasties and dynasties of China, no one used iron to make money.

It's not that there isn't, but the big ones unified the orthodox imperial court, and they all used copper to make money. Iron is too cheap, easy to imitate, and too easy to get tiny. This money also represents the prestige of the imperial court, and unless there is really no way, it is rarely used to obtain iron money. will use iron money, many of which are chaotic or short-lived regional regimes.

Li Chen dared to switch to iron money, and naturally he had his reasons. First of all, no one found out that this was iron money, (the economic promoter of the Tang Dynasty in a certain area: Who said that we have found out that you, the emperor, have no conscience than us.) ）

To have such an effect, it all depends on the electric method. Li Chen, who had also worked in engineering for several years, still remembered this kind of technology, which was very simple. As long as the negative pole is connected to the iron plate, the positive pole is connected to the copper plate, put it into the copper sulfate easy middle, and connect it to the electricity, you can use the electrode.

Where's the electricity? Don't forget that Li Chen was in Yangzhou, he was a magic stick once, and the power generation was nothing more than cutting the magnetic field, and he had already made the generator. Of course, the power is different, but the power generator used for electric power is also used for the hydropower of the Wei River.

As for copper sulfate, it is not a problem, and the Tang Dynasty has already appeared a technology for extracting copper from copper sulfate, which is called water immersion copper.

Dry water is natural copper sulfate liquid. In these days, it has been discovered that if you soak an iron plate in water, and if you soak it in water for a few days, red coal will be formed on it, and copper will attach to it, and if you remove it, you can use it for refining copper.

Honestly speaking, this kind of technology takes copper, and in fact it can be saved. However, Li Chen was still not satisfied. Take iron plate bronze and disguise bronze money, which is even more economical and earn more. Millions of profits are made every year, and part of it comes from this, taking iron money and copper, and iron money turning into copper money, which is not only anti-plaster, but also easy to accept, and saves costs.

Speaking of which, this electric bronze technology is not easy either. Li Chen proposed a method, and Gao Da, Luo Qing, and Pingdao led a few people to study it together for a long time.

Technically, it's very simple. In reality, however, it is not easy to fully apply it to the economy. Iron bronze and water immersion bronze can be completed. But that kind of technology takes many days. The iron should be soaked in the water and soaked for many days before the iron will be stained with some red copper.

Time is one thing, and they can't wait that long. Second, it is also a question of how to make iron and money iron and bronze evenly. Again, the iron and bronze will be stripped off, and if the craftsmanship is not passed, the copper skin will fall off in a short time.

In order to solve this problem, several people forgot to eat and tried desperately to test. It depends on whether it is necessary to increase the strength of the water and the copper separation, or to increase the electric current, so that the goal can be reached. Seriously, the cost behind this money is quite a lot if you add in the R&D expenses.

As a matter of fact, we have already saved a lot of money by using water alone to charge the cost. It's just that the amount of copper ore is not in supply for a certain extent. Li Chencai will simply adopt new technology and use electric methods to turn iron money into copper money. After that, he will consider gradually eliminating this money and using it to make real money.

Secondly, this can be regarded as promoting the development of Datang's science, what is the degree, copper, electricity, a few words, literally just a few words, but behind it represents a lot of things, using this opportunity, let them sum up, I don't know how much scientific and technological strength Datang can be improved. However, that was a long time later.

This is a copper coin, and in addition, when it is above five dollars, it is a new technology, which is not provided by Li Chen, and he has not learned this technology before, and he does not know when China will have it, and he still learned it from India.

This technology is called copper, which is metallic metallic. Li Chen introduced the Copper Extraction technique from India, and then used it for money.

Metal copper, iron on iron, Li Chen knows, everyone must have seen it, that kind of iron skin is bright and shiny, is copper. This is a very common, very economical, and very effective anti-modalism technology. Heat-soaked copper, especially common, has been in use for 180 years since it was invented, and in the 21st century. These are the things that Li Chen knows.

However, he didn't know that Datang didn't have such things at all. He had been paying attention to it at first, and the reason was that he had mentioned too much, a bolt. It's a good, very economical way to prevent the smell, and I didn't think that this thing would be used to make money. But I didn't expect to find such a thing. Even the iron-eating beast doesn't know.

The iron-eating beast, a friend of Gaudda, is also a weirdo anyway, and when his surname is around, this surname is very rare. Because he likes to play with metal so much, he also has a furnace for refining iron in his house, which he will use to refine all kinds of metal when he has nothing to do. Or try to mix them. As a result, it got such a nickname.

The iron-eating beast didn't have the slightest impression of Li Chen's proposed metal characteristics. He likes to play metal, he naturally knows raw metal, and has done a lot of comparisons to see which kind of metal is easier to produce metal, but he has no impression of the characteristics of lithium proposed by Li Chen.

Until Li Chen said that he could refine yellow copper with copper, he had an impression, yellow copper? Brass... It turned out to be this way. , iron-eater, muttered to himself.

It turned out that at this time, there were merchants in the Western Regions who used fool's gold and disguised it as gold to deceive people, saying that it was fool's gold, but it was not all, and many old merchants were deceived. But his gold is like gold, and he is not fool's gold, and as a result, many people are deceived.

Fool's gold is yellow iron mine, and its main ingredient is iron disulfide. This thing has existed since ancient times, and because it is very similar to gold, it is often misunderstood. However, experienced businessmen know how to distinguish this thing.

And the iron-eating beast said that it was Fool's Gold, which was similar to Fool's Gold, and it was also very similar to Yellow Gold, but he didn't have the characteristics of Fool's Gold. Fool's gold is brittle, and it shatters when you knock it, but this kind of Fool's gold is very hard.

He was very interested in this kind of thing, and tried every possible way to figure out that this kind of thing could be obtained with a kind of mineral called calamine, with a pound of refined red copper, mixed evenly, plus charcoal, put it in an iron pot, and burn it. After two days of burning and then three hours of intense fire, this is what is brewed.

Unlike red copper, this mixture of red copper and calamine is yellow, which should be what you call bronze, but calamine is not as you say.

Li Chen was a little disappointed, but he still remembered this technique. In the future, you can use this technique to train out the yellow copper money, or maybe you can make up for the lack of Tang copper money.

Later, when he was looking for cotton technology in India, he was surprised to find that India actually had such technology. Put calamine and charcoal into a sealed jar and burn it on a large fire, so that you can get high-purity metal copper at the bottom of the jar.

This was really overjoyed, and of course Li Chen also got this technique back, and listed it as highly secret. Li Chen hoped that this technology would be as long as possible, as long as the technology was not cracked, he would be able to rely on this skill to make a lot of money. This should not be impossible.

Because when the yellow copper was refined, Li Chen suddenly understood that the technology of refining metal metal metal probably appeared very late in China. Because after he came to the Tang Dynasty, he didn't find it at that time, and now he thinks that the copper money in the Tang Dynasty is all green and green.

This is a symbol of bronze, and the real copper is red. It is too soft, there is no way to use it, it is necessary to mix it with a tin to make bronze, and the hardness is a little higher.

But whether it is a real object, or a TV series or movie, what you see in it is that the Qing Dynasty got bronze money, which is yellow, bronze.

That is to say, probably during the Tang and Song dynasties, there was no breakthrough in the technology of refining metallic metal, and most of them were like this, mixing red copper, staying up for a few days and nights, before it was realized. In fact, Li Chen really didn't guess wrong. (To be continued.) )
