Daming: I, Yang Xian, really govern Yang!

Chapter 58 Yang Xian’s Third Five-Year Plan

night.

Beijing.

Duke of Wei.

Xu Yungong knocked on the door of her eldest sister Xu Miaoyun's study. After getting a response, she carefully walked in and bowed respectfully to Xu Miaoyun who was calculating the expenses of Xu Mansion.

"Sit down." Xu Miaoyun said without raising her head.

"Sister, the reason why the younger brothers and sisters cooked the roasted goose was to please their father." As the eldest brother, Xu Yungong explained the behavior of his younger brothers and sisters during the day. In fact, he was also involved.

In the family, these younger brothers and sisters are not afraid of Xu Da, the head of the family, but they are more afraid of Xu Miaoyun, the eldest sister.

"Dad has always been a little depressed these days. As you know, eldest sister, before His Majesty conquered the North, dad was the coach. But this time." At this point, Xu Yungong also felt a little sad and couldn't say any more.

"After eating roast goose, you hurt your body and feel happy?" Xu Miaoyun put down the pen in his hand and raised his head to look at his younger brother. "Besides, in terms of duties, my father is already the Prime Minister of the Central Committee of the Communist Party of China. In terms of titles, our family has also been granted the title of Duke a long time ago. Everything must be reserved. Don't you understand such a simple truth?"

"This time dad was called back from the northern border, it would be better to stay in the capital. Don't look at our Xu family. Now we see that Long En is in full bloom, but you have to know that there are flowers blooming and fire cooking oil. The more careful you are at this time, .”

Xu Miaoyun sighed and stood up.

Prosperity and decline.

During this period of time, she had read eighty episodes of Red Mansions, and she could already deduce the decline of Ning Rong's second mansion as far as the eye could see.

Xu Miaoyun looked at Xu Yungong and said, "I know what's on your mind. Isn't it that Li Jinglong from Duke Cao's mansion went with the army to the outside of the Great Wall this time, but you can only watch helplessly?"

"Yun Gong, my family should know their own affairs. Our Xu family is different from Cao Guogong's palace. His Majesty Cao Guogong's nephew."

"I know, eldest sister." Xu Yungong said.

Yang Xian in Yangzhou.

I never thought that such a large-scale Northern Expedition would be related to him.

If you want to set up wool processing workshops across the country, you will need a lot of wool.

Today’s Daming breeding alone is obviously not self-sufficient.

So our old Zhu waved his hand and set his target directly in Mobei beyond the Great Wall!

Of course, there were many reasons for launching the Northern Expedition, but undoubtedly, this was one of the reasons that was not too small.

At the same time as the mighty army set out.

Yang Xian's Yangzhou Primary School is under construction in full swing.

In order to distinguish it from the old private schools of this era, Yang Xian decided to use modern architecture.

To build a modern small building, the first material needed is cement, followed by red bricks.

There are alternatives to red bricks in this era.

You can only fiddle with the cement yourself.

In ancient times, lime was basically used in building houses.

Lime, sand and gravel are mixed together to make lime mortar, but such a simple lime mortar is not very effective.

No, it should be said that there are many problems.

For example, due to insufficient strength, tall and large houses cannot be built.Moreover, in addition, once the weather is bad and the environment becomes humid, it will be impossible to build a house, which will greatly delay the work time.

Later, in order to solve these problems, people thought of many ways.

For example, adding yellow clay to lime mortar can not only work in a humid environment, but also solve the hardness problem.

Another example is adding glutinous rice to lime mortar to form glutinous rice lime mortar.

As we all know, glutinous rice is very sticky, so the sticky effect is also very good.Glutinous rice lime mortar is mostly used to build palaces, and is also used in fortification construction. In any case, this raw material is not available to ordinary people.

Ordinary people don't even have enough to eat, so how can the "rich" people use glutinous rice to build houses? They are reluctant to part with it.

But no matter what is added to it, it is still gelatin.

Compared with cement, lime has obvious disadvantages.

This is why the lime craft that has been passed down for thousands of years was later replaced by cement.

The first point is that it is difficult to store lime.

Quicklime should be stored and kept in a dry environment. If the storage period is too long, it must be stored in a closed container.In addition, it is necessary to prevent the lime from getting damp or hydrating when exposed to water, or even causing a fire due to the concentrated release of slaking heat.

The second is constructionability.

Cement is far superior to lime.

Cement can be mixed and used immediately, but lime cannot. If lime is used immediately after hydration, it will damage the wall surface and greatly reduce the structural strength.

The last step is to deal with more complex changes in building structures.

Cement has high density, and when mixed with sand and gravel and water, it becomes harder and more resistant to frost and wear, and has strong anti-permeability, making it better for building safety and insulation.

Like asphalt roads, Yang Xian did not just engage in cement to build a school.

If you just want to build a school, even if you want to build a high-rise building, although the effect is not as good, you can still achieve the purpose with blue bricks and glutinous rice mortar.

Half a year ago, before Zhu Yuanzhang left Yangzhou, he set the "Third Five-Year Plan" for Yang Xian, which was to have a good harvest in Yangzhou in three years and rebuild Yangzhou in five years!

Yang Xian also has his own Third Five-Year Plan.

His sight is not just Yangzhou.

Yang Xian looked at the system, his eyes slowly becoming far-reaching.

[The host is within the territory and ignores any damage. 】

"According to your instructions, the furnace is ready." At this moment, Lu Mingyi walked in from outside the house and said.

Just a dozen days ago, Lu Mingyi suddenly received a task from Yang Xian and gave him a design drawing, asking him to lead the craftsmen in Yangzhou City to build the furnace according to the drawing.

This was the first time Lu Mingyi had seen this style of fire kiln.

Although he didn't understand the purpose of this thing, since it was Yang Xian's order, it must have far-reaching significance.

Maybe it will be another great thing that benefits all people.

Lu Mingyi naturally did not dare to neglect and immediately led people to build the furnace himself.

During the entire process, he personally supervised the craftsmen and worked overtime day and night.In his heart, Mr. Yang worked hard to invent this and that for the sake of the people of the world.

And he was just doing some manual labor, running errands, so it was not hard work.

These days, while Yang Xian was eating hot pot, singing songs, drinking wine, and admiring the snow in the government office, Lu Mingyi and all the craftsmen were eating and lodging at the construction site.

But he had no complaints or regrets. He only hated that he was not capable enough and could not share more for Yang Xian.

"Thank you for your hard work, Master Lu. Come on, take me to see you." Yang Xian patted Lu Mingyi on the shoulder and said with a smile.

"Yes, sir!" Lu Mingyi replied loudly.

After receiving Yang Xian's affirmation, Lu Mingyi's body became straighter.

　One place was modified. All the places where Xu Huizu appeared in the previous article were changed to Xu Yungong. I forgot about it. He had not changed his name at this time.
