When Wang Yan heard the word "send-off", he hurriedly stood up in fright.

He said respectfully: "King, don't stop here, don't stop here!" Since the Dharma King doesn't want to tell me to wait, forget it! Never mind! The rest of the business can still be discussed, can be discussed! ”

Yan Zheng looked at him playfully and said, "I know what you are thinking, but I also ask you to understand that it is okay to come to Dongqin to do business, and it is better not to have other thoughts!" ”

Wang Yan hurriedly said: "Whatever the king says, it's what it is!" ”

Yan Zheng smiled, waved his hand and said, "Sit down!" Ningbo Mansion, there is already a Zhang He, to be honest, this business, if you want to do it, it depends on what conditions you give. ”

Wang Yan thought for a while and said: "Fur, threshing machine, these two things can be handed over to me, and I can increase the price by one percent as much as Zhang He pays!" ”

"No!" Yan Zheng shook his head and said: "The price is the same, but for the rest of the conditions, how much can you give?" I forgot to tell you, Zhang He colluded with the pirates, and there were a lot of people transported each time. ”

Wang Yan was stunned for a moment, he knew that Zhang He had colluded with Haize, but he didn't know about this matter of transporting people.

He said tentatively: "What does the king mean, do you want a population?" ”

"That's right! Other merchants who came to Dongqin to trade all needed a sea introduction document issued by us, which cost 10,000 silver. But the Ming businessmen are different, the Ming businessmen want to send the population! Yan Zheng said.

Wang Yan thought about it in his heart, and after a long time, he nodded and said, "No problem! ”

Yan Zheng smiled with satisfaction: "Don't worry, there will be more and more good things in Dongqin, and you won't lose money in this business!" ”

Wang Yan also smiled, and arched his hand: "Then dare to ask the king, how is this threshing machine sold?" ”

"What's this, you ask?"

"The king doesn't know, there are thousands of farmers in the Ming Dynasty, this thing has a broad prospect, and my lord has a good life to run it! He said that this business is done well, and he can accumulate virtue! ”

Yan Zheng thought about it for a while, and said nonsense: "This thing is in the Ming Kingdom, and it doesn't sell very well!" However, in Japan and the Ryukyus, tens of thousands of units can be sold every month! ”

"Tens of thousands!" Wang Yan didn't understand overseas things, so he really believed it, and he estimated that if there were more than 100,000 threshers in the whole of Zhejiang, it would be almost enough.

"This ...... This king, the Ming Kingdom must have more land farming than Japan and the Ryukyus, as long as the king has the goods in his hands, how many will there be in the future, how many we want! ”

Yan Zheng nodded, and said curiously: "Why does your lord value this business alone?" ”

Wang Yan smiled, and said lightly: "Wang, other businesses can naturally make more profits, but just take this fur as an example, it's not that rich people are willing to buy it and wear it, but this threshing machine is different, as long as it is farming, it will naturally try to get one!" What's more, the king sells it so cheaply! In the long run, it's big business. ”

"You've made it?" Yan Zheng asked with a smile.

Wang Yan was stunned, nodded with a wry smile and said: "I don't know the king's method, a thresher costs at least two taels of silver, and each one needs more than a month to build!" ”

Yan Zheng was secretly relieved in his heart, what is called productivity, this is called productivity! The textile industry can still resist a resistance, but this steel industry is really powerless.

"Okay, that's all there is to say about this matter, you just go to the official in charge of the Ministry of Foreign Affairs to sign a contract, now the salt port has not yet established a customs, and there is no need to negotiate a tariff for the time being, and when the customs is established, I will inform you!"

Wang Yan nodded: "Thank you, King!" ”

"No thanks, also, remember to find the Ministry of Foreign Affairs and buy a copy of the "Huaxia Foreign Business Law", there are relevant legal provisions in it, you remember, when you act in Dongqin, you must abide by the laws here, and you will be prosecuted if you violate the law!"

Wang Yan arched his hand and said: "Certainly, definitely!" ”

"Well, stand down!"

Wang Yan got up and saluted again, and then slowly exited the room.

After he left, Yan Zheng had some doubts in his heart.

It stands to reason that the fur trade is a more profitable business, but this person's focus seems to be entirely on the threshing machine.

However, after the converter is built, the steel industry will explode in capacity.

After having a few barges, Yan Zheng is ready to vigorously expand the industrial population, the reason is that the grain reserves, which can already be partially solved by transportation capacity.

At this time, we should focus on industry, exchange industrial products for food, and transfer some of the contradictions to other countries.

…………

With some doubts, he turned and went up to the second floor.

The students here are all from the former senior class, and because there are many empty rooms, they are divided into three groups, one is the mathematics group, one is the physics group, one is the chemistry group, and one is the biology group.

Being able to enter the senior class means standing out from the teaching, these people are not bad brains, and their hands-on ability is also being cultivated.

The class group he was going to teach today was the chemistry group, and when Yan Zheng walked in with the textbook, they were conducting a very simple chemistry experiment.

After knowing the characteristics of potassium nitrate, they used a certain method to produce potassium nitrate with higher purity from the nitrate soil of the nitrate.

Yan Zheng stared at it for a while, and found that they still had no progress after a few days, and the method they were using now was still learned from the nitrate workers.

Although those boilers did not know so much knowledge, they had enough experience, and after a conversation, these students learned a set of methods.

This made Yan Zheng a little dissatisfied, but there was no way, these people were all chemical rookies, and it was rare to be able to get them.

"Ahem!" He coughed, and the students immediately realized that class was in place and immediately sat down obediently.

Yan Zheng walked to the blackboard and said, "Students, let's continue the class today, we learned the periodic table last time, and also knew about oxidation reaction and reduction reaction, as well as some simple chemical knowledge. Today I'm going to talk about the chemistry in steelmaking! ”

As he spoke, he wrote down a few simple element symbols and Chinese characters on the blackboard.

"In iron ore, half of pig iron contains many other elements, and these elements have a very large impact on the properties of iron, such as too much sulfur and phosphorus, which will make iron brittle! Of course, these can be removed by adding some substances, and what this unit wants to talk about is how to add substances and how to control the carbon content of steel! ”

The students took notes, and the people in the chemistry group were lucky, at least their lessons were interesting and tight, what coarse salt became fine salt, what boiled urine got salt, they could have fun.

Yan Zheng also said happily that he was too timid, and for the sake of the chemical industry, he deliberately recruited more than a dozen students into the chemistry group.

Only by letting them learn can he dare to establish a sulfuric acid project, and with a sulfuric acid project, there can be nitric acid and alkali.

It can even be said that once the output of sulfuric acid rises, many industries will be very different, and the first is printing and dyeing and papermaking.

While talking, he described it vividly, and also asked students to visit the steel mill by the way.

"Teacher, why does the carbon content affect the quality of steel, and carbon and other elements, only 1% can affect the overall properties of iron, why?" A Ming boy named Wang Erhu scratched his head and asked.

Yan Zheng can only say that this problem is very good, in fact, human beings have been making steel for so many years, and this problem has not been solved.

It was not written in the soil law booklet, but it did not affect Yan Zheng's nonsense: "To use an inappropriate analogy, when we stew meat, do we only add a little salt to make the whole pot of soup taste?" ”

Wang Erhu nodded.

Yan Zheng smiled: "Isn't this it, the reason is the same!" This is because these substances can become very small molecules, and the interaction between these molecules will affect the properties, and the teacher does not know much about this! ”

"But you're going to think of it as a stir-fry! Later on, you'll find that adding something else to the molten steel will make the properties of the steel very different. The impurities in these molten steel are not necessarily a bad thing! ”
