Chapter 55 Soil Cement

Yu Xing didn't speak, he directly gave the letter in his hand to Zhang Yunqing.

The grievances were like this letter, pressing on Zhang Yunqing's heart.

She knew that this time the alliance was essentially a political meeting, and Yu Xing's concubine was just a pretext.

She and Yu Xing just bowed in front of the grave, used some dry food, and got married.

marrying a daughter from a luxurious family, but making it so grand.

How her heart is tasted.

It's just that there are all kinds of feelings in my heart, but it's hard to say, but I said with a smile: "I can't care about other things, but taking a concubine is a family matter, you can rest assured." I'll cook it for you. There won't be a single slip in the cracks. ”

Yu Xing wanted to say something, but Zhang Yunqing had already left. Said to go and arranged.

Yu Xing could feel Zhang Yunqing's inner entanglement, but he really didn't have time to have a long relationship with children.

Yu Xing has more important things to do.

First of all, the organization of steel production.

This time, we need to learn from the lessons of the previous time and balance the efficiency of all mining and transportation departments as much as possible, so as to maximize the efficiency of the blast furnace and continue to produce.

The second is cement.

Build a city in three years.

Yu Xing naturally refused to accept it.

It's too slow.

Yu Xing knew very well that now on the Guangdong side, hundreds of thousands of Tartar troops were surrounded on all sides and were uprooting the strongholds of the Song army on the shore. Because of this, even if the Tartars knew that Yu Xing was here, they would not send many soldiers and horses.

Now is the golden age of his development.

Time waits for no man.

We must hurry.

If you want to build a city in a short time. Naturally, it is necessary to go to technology.

Cement.

Modern labeling cement, naturally, is impossible. There is no problem with soil cement.

This is just a matter of engineering, Yu said.

Making cement is simple and simple, that is, several raw materials, grinding and crushing, and sending them to the furnace for burning. It's the most high-tech cement production line, and that's it. Although the principle is simple, it is not simple to subdivide.

The core problems of manufacturing cement.

The first is raw materials. It doesn't matter if it's limestone, or a variety of other raw materials. Bijie is available locally.

Most of it is coal.

Guizhou is known as the southwest coal sea, and Bijie is one of the major coal-producing cities in western Guizhou.

Having enough fuel is the foundation of the iron and cement industry.

The second is blast furnace technology.

Cement also needs to be fired. When Yu Xing was already researching iron smelting, he had cleared the customs once. Although the requirements for cement furnaces are different from those for iron smelting. But in Yu Xing's opinion, it's just a change of vest, and there is no problem.

Finally, it's the ink grinding technology.

That's the problem.

If the cement is ground into powder by hand, it naturally has no technical content at all. After all, flour existed in the Han Dynasty. Not a problem at all. But efficiency is a problem.

The Bijie City that Yu Xing wants to build is not big.

The circumference is no more than four or five miles. All you need to do is protect key industries and lock up traffic arteries.

The amount of cement will not be too much.

But even so, if you let people grind by hand, it may not be possible in three years.

This is the technical difficulty that needs to be overcome.

It's hard to wake up.

Yu Xing quickly devised two schemes, one wind and one hydro. That is, the wind mill, or the water mill, which has long been a ready-made solution in ancient times. The only problem is that someone else uses to grind flour, he uses to grind clay, slag, limestone.

In short, a series of integrations down.

All the problems are broken down into a project that can be completed step by step.

Yu Xing took the students of Dunzhou State School, as well as some laborers, and there was no problem that could not be solved in all construction.

It's just that Yu Xing soon found a problem that he couldn't solve, and it couldn't be mass-produced at all.

The problem is not that there is anything wrong with Yu Xing's technical solution, Yu Xing has been simplified to the extreme because of ugliness, and it is the local law in the local law. Even for the sake of technological simplification, the shelf life was compressed: up to ten years.

This leaves nothing technically problematic.

The problem is that there is no one.

Yes.

Lack of labor.

In order to conduct large-scale transactions, Long Zexi organized large-scale iron smelting with Qixingshan in the Iron Prison. All require manpower. And there are so many people under Yu Xing's command. Human resources are given to the iron smelting department.

Yu Xing can come over.

But there are priorities, and Yu Xing knows it.

The iron-smelting sector is important, and so are other sectors. The civil affairs department under Qiao Jian's control, as well as the most important army, cannot be arbitrarily transferred manpower.

Yu Xing went around and could only produce soil cement on a small scale, and taught the children by the way.

Waiting for other manpower to have leisure, or the arrival of the Han labor force he had been looking forward to.

Speaking of which, the students of these state schools have not attended classes for a few days. For so many years, I have only learned four operations, and I have often used Chinese characters to write them. And with a pencil, not a brush.

If the Great Song scholars read it, they naturally feel that there is almost no difference between learning and not learning.

Here in Yu Xing, he directly took these people to participate in the development of soil cement, on the one hand, these people are also labor. On the other hand, I want to cultivate their scientific spirit.

The scientific spirit, or rational thinking, is a very practical methodology in itself.

As long as anyone can understand and master this methodology, even if they don't engage in scientific research, they can use it to solve many practical problems.

Yu Xing was a teacher after all, and since these students called him a teacher, he always had to teach something real.

********

Li He and his entourage worked hard and crossed mountains and mountains to bypass Mei Guozhong's camp. I came to Manbe.

Manbe immediately gave him a great shock: in just three months, Manbe was no longer the Manbe he knew.

The people he knew were no longer in Mangbu, and it was easy to find an old acquaintance: Zhao Dayan.

Zhao Da was very happy to see Li He, and said: "Senator Li, the son often talks about you. You're back. ”

Li He said: "Don't talk nonsense, what's going on? Where are Childe and Miss? ”

Zhao Dayan told Li He about what happened after Li He left, and said, "Senator Li, go to Qixing Mountain quickly." Miss must miss you very much. ”

Zhao Dayan's words made his face a little speechless and stopped.

Li He saw it at a glance and said, "What happened?" ”

Zhao Dayan was a person who couldn't hide his words, and then told Yu Xing about marrying a daughter from a luxury family. said indignantly: "A manly man, there are a few more mothers-in-law who have been nested, that's not a thing, but the pomp of the luxury family is obviously better than that of the young lady, and I feel uncomfortable." ”

Li He's attention was not on this one thing.

It's not that he doesn't have a deep relationship with Zhang Yunqing and can't think about Zhang Yunqing, but Li He can see things from a higher perspective.

It's just that Zhao Dayan doesn't think it, in fact, he is the starting point of Zhang Yunqing's grievances, and it is not so simple, he joined the Yuxing group with Zhang Yunqing, and he is naturally a member of Zhang Yunqing's faction. Yu woke up a few more women, and he felt that it would not be a problem. But other women have overpowered Zhang Yunqing, that is, other factions, and it is possible to overpower them.

That's it.

Li He understood Zhao Dayan's thoughts, but he knew better that if Yu Xing failed to achieve a great cause, none of them would end well, compared to this, some of the things that children were in love with were not worth mentioning at all, what he cared about most was the help that this marriage brought to Yu Xing.

Li He said: "The daughter of Ayongbu Haoxiong? ”

Zhao Dayan said: "Yes, yes." That's him. ”

Li He secretly said in his heart: "It's really an old acquaintance." ”

He immediately thought of the influence brought by the marriage with the Ayong Ministry, at least among the six ancestors and the nine tribes, Yu Xing had allies, and the Ayong Ministry was very close to Lingxiao City, so he might be able to get in touch with Lingxiao City through the channels of the Ayong Ministry.

Wait a minute.

Regarding Zhang Yunqing's grievances, Li He could only sigh.

I had just returned from an enemy-occupied area, and I saw that my eyes were full of devastation.

Compared to these, Zhang Yunqing's grievances are nothing.

Li He diverted the topic: "Why are you here?" ”

Zhao Dayan said: "I was ordered to supervise the grain, and this is not about to be harvested in autumn." Before the autumn harvest, the grain stored in Mangbe should be transported to Qixing Mountain and set aside in the warehouse. ”

Li He looked at the fields in Mangbe and also felt that the growth was good.

After all, farming for others is a completely different feeling than farming for yourself.

"Senator Lee." Zhao Li said: "I want to see Mangbe, is it okay?" ”

Li He said: "Zhao Gong, if you want to see it, you can naturally do it." I was tired from the journey. Just take a half-day break. ”

Zhao Li nodded, and seemed to visit Mangbu. Talked to the people of Mangbe and went to see the embankment designed by Yu Xing. and thousands of acres of paddy fields that have been planted with rice.

Zhao Li was not surprised by the embankment designed by Yu Xing, he didn't know how many water conservancy projects there were in the water towns in the south of the Yangtze River, but he was amazed to learn that Yu Xing had completed most of the projects in less than a month.

Others don't know, but he does. He was in charge of water conservancy projects. Naturally, I know how difficult it is.

After this trip, Zhao Li became more and more curious about Yu Xing.

Zhao Li has never been a big official in his life, but he is not incapable, on the contrary, he has been in the county and county orders for many years, and when he is old, he found an idle job in Beijing to retire.

But because Jia Rudao and others were in turmoil, he was stubborn and stubborn, so he naturally couldn't rise.

However, he has a lot of experience in local governance.

Observing everything Yu Xing did in Mangbu, he secretly said in his heart: "Yu Xing, this person, even if he doesn't talk about leading troops to fight, he can be a famous minister." It's just a pity. ”

In his opinion, after Yu woke up to the famous family, he had a good future, made greater contributions, and became one of the famous ministers, but at this moment he could only find a glimmer of life in the poor mountains and bad waters.

Zhao Li's heart of wanting to see Yu Xing became more and more urgent.

I can't wait for a moment.

Under Zhao Li's supervision, Li He could only speed up his trip.
