"Establish a heart for heaven and earth, establish a life for the people, continue to learn for the saints, and open peace for all generations", these are the four sentences of Hengqu by Zhang Zai, a Confucian scholar in the Northern Song Dynasty.

Zhao Yunrang, who has a heart to open a peaceful and prosperous era for the Great Song Dynasty, is squatting in the newly built house at the moment, studying the earthen stove with Lao Li Tou and others.

Since ancient times, there is a saying in the construction industry that "the soil is not moved in winter", which means that the weather is too cold in winter, not only is it not easy to take the soil, but even the house built will inevitably freeze during the day and at night, and it will not be solid if it is barely built.

This is true of mud-brick thatched houses, and brick houses are no exception.

Therefore, it is not easy for Zhao Yunrang to build the school before it freezes.

As for the arduous task of transforming the entire Zhuangzi, it can only be put on the beginning of spring next year.

Early in the morning, Lao Li Tou and the dog were already standing on the playground with the team.

Zhao Yunrang's purpose in convening them was simple, that is, to hold an on-site meeting about the earthen stove.

This earthen stove is actually similar to the firewood stove, mainly the inner circle and the outer square, the lower side of the air outlet and the place to dig out the ashes.

Inside, you need to put a hearth, which is very skillful.

If it is good, the furnace is prosperous, and it also saves coal.

Not to mention the bad waste of coal, watching the fire suffocate and half-dead, can be depressed and dead.

Although Zhao Yunrang couldn't actually operate it, in his previous life, he saw his teacher build a stove and set a stove every year.

So standing aside for professional theoretical guidance, Lao Li Tou and the dog got started directly, and within half an hour, the stove was built.

After building the stove, Zhao Yunrang discovered a key problem, that is, there was no chimney.

I'll go for it, is there a place to wholesale cigarette barrels in Da Song now?

As a result, he was despised by Lao Li Tou, and the chimney had to be built, which is not called a chimney, but a flue.

It is the same as the stove, but this flue goes alone, and the flue that has been reserved for a long time is connected to the wall.

Lao Li pointed to the wall, where the flue had long been left.

And above the house, the stone-carved four-cornered beast pavilion is the smoke outlet of the flue.

If this is put in the modern era, it is the art of architecture.

Actually, it's true, the art we see is actually the life of our ancestors.

The stove was built against the wall and was connected directly to the flue.

Anyway, it is an experimental nature, and this furnace is also a base every year, so it has become a test site for dogs and others.

I got some firewood, grass and branches, lit a fire, drew coal, and ho, when it wasn't freezing, it was a little too hot in the house to stay.

Another room was changed, this time the stove was placed in the middle of the room, and as for the flue, it was directly bricked.

In order to prevent overheating and scalding the children, Lao Li Tou also used finely sifted clay, mixed with wheat straw, to thickly "put on a layer of clothing" on the outside of the flue.

Lao Li Tou said that in some big households, this is also a must, called Dilong.

Zhao Yunrang nodded, and then smeared some green ash on it, and the children could sit directly as a stool when they read.

When the time comes, it will definitely be a sought-after position in this classroom.

But this thing is too troublesome, and it has to be like an ant for the winter every year, and it's better to have a chimney.

Zhao Yunrang: "Isn't there a place to sell cigarette tubes?" ”

Lao Li raised his head with a brick knife: "What cigarette tube?" ”

Zhao Yunrang: "Uh, it's a chimney, have you heard of Qu Tu Migration?" ”

The crowd honestly replied, "No." ”

It's really a cow playing the piano, "It's a surprise!" ”

"Understood," Lao Li Tou immediately called the dog and the man to bring a few, "That's it, some of the flues in the wall are made directly from mud, and some are made of this." ”

Zhao Yun let vomit blood, section by section of clay fired chimneys, things are of the same nature, but this thing can't be used to connect the stove.

If nothing else, the tar problem cannot be solved even by iron chimneys.

Instead, it was all built of bricks and wrapped in mud at the end, which solved this problem.

However, the problem of flue blockage is not easy to solve.

The best solution, of course, is to use an iron stove and a matching iron chimney.

However, at present, Zhao Yunrang is not clear about the level of iron-smelting technology of the Great Song Dynasty.

However, there is one thing that Zhao Yunrang knows, this iron, as the main raw material for the manufacture of cold weapons, is forbidden to be operated privately in the Great Song Dynasty.

Maybe it's not difficult to find a blacksmith shop and build a weapon, Lu Zhishen has built a water mill Zen staff, which is dozens of catties of iron.

However, with a large number of thousands of pounds of iron, it is estimated that the security department of the Northern Song Dynasty should come to talk to someone.

This is also the reason why Zhao Yunrang did not plan to use the iron stove in the first place.

What I'm afraid of is that the foothold is not stable, and the tree is big - of course, Zhao Yunrang didn't know that a demon wind that had arisen because of him had quietly blown.

Since the flue did not work, the only way to make iron chimneys was to make them.

Lao Li Tou was surprised: "Iron can also be used to make this?" ”

Of course, in fact, an iron stove is really easier to make than a chimney, and only a sand fan is needed.

Zhao Yunrang immediately asked people to go to Daxiangguo Temple to recruit two blacksmiths, but before anyone went out, they were blocked back by the old Zhang Tou in the village.

"I'm the blacksmith!" The old man patted his chest.

Zhao Yunrang was speechless, you are a blacksmith and you have to have tools, basic stoves and the like.

As a result, Lao Zhangtou led Zhao Yunrang to the backyard of his house, and under the two shabby reed mats, it turned out to be a dilapidated blacksmith furnace.

It is said that this is still the person who was going to be the prisoner here and didn't know what to do, so Lao Zhangtou followed and learned a few hands.

This village is really a hidden dragon and a crouching tiger!

Zhao Yunrang simply told them the steps to make the cigarette tube.

As a result, Lao Zhangtou nodded and shook his head.

Zhao Yunrang wondered: "What's the problem?" ”

Lao Zhangtou frowned: "I understand what the little prince meant, but the temperature of this furnace may not be able to keep up, and this iron will cool too quickly when the time comes——"

Soon, the first chimney was made, probably because it was made for the first time, and the iron was not yet ordinarily thick.

Well, if there are no bubbles or anything like that, you can use it directly to make a redcoat cannon!

It's still a matter of furnace temperature.

Zhao Yunrang thought for a while: "Don't you have a tool to blow the wind?" ”

"Yes, we use the sling!"

Basketry?

This is too primitive, Zhao Yunrang shook his head, it is estimated that it is still the kind of manpower, not even the water row and the wind.

"Old Li Tou, when you get the firewood stove, remove the bellows that come with it!"

Piston type wooden bellows, one person can greatly increase the furnace temperature.

I got two piston wooden bellows and connected them to both sides of the blacksmith's furnace, and the two sons of the old man pulled them together, only to see the flames dazzling.

"If I can't make a suitable cigarette pipe this time, I'll replace it!" Zhao Yun gave an ultimatum.

Lao Zhangtou was very excited: "Don't worry, you can't get it out, and our grandfather won't have the face to see you!" ”

If you want to do a good job, you must first sharpen your tools, this sentence is still very reasonable.

As soon as this bellows was used, the furnace temperature increased a lot.

The impurities of this molten iron have also been improved to a certain extent.

The chimney that was finally created finally passed Zhao Yunrang's assessment.

Of course, this is purely handmade, which is obviously time-consuming and labor-intensive.

Zhao Yunrang gave a rough hint of how Lao Zhangtou made the molten iron out of a thinner sheet, and then used the rolling paper method to make it.

And also deliberately stipulate the caliber of the chimney, this thing, it is inevitable that someone will imitate it.

It's always a good idea to plan ahead.

Soon, the newly built stoves in this row of classrooms were all connected to the tin chimneys.

When a fire was lit, the chimney immediately burned his hands.

After a while, the room was so hot that people couldn't stand still.

In the winter, I came to study in this room, and it was a happy thing to think about, and this is the feeling of spring indoors.

It was so hot in the room that he was sweating, Zhao Yunrang suddenly thought of a very important question, and couldn't help but slap his thigh!

The old Zhang Tou, who had been following for several days, immediately came up: "Young Master, what else do you have to order?" ”

Zhao Yunrang didn't think about anything else, and asked, "Do you know how to grow vegetables?" ”

Lao Zhangtou is a little dissatisfied, who in the village can't grow vegetables these days? It's not a special skill!

"When it comes to growing vegetables, no one dares to say that I am ranked second in Zhuangzi!"

Zhao Yun was overjoyed: "Okay, it's you." ”

As a result, Lao Zhangtou was dumbfounded: "What? Growing vegetables at this time? ”

Seeing that the frost has passed, and winter will begin soon, how can there be vegetables in this season?

Zhao Yunrang doesn't care about this, he really vomits after eating Chinese cabbage every day for a while.

There are still a few empty houses above Zhuangzi, and the windows are glued tightly with good window paper, and there is a stove inside.

Coal was shipped directly from Lao Zhou.

I have to get a warm house and get some greenhouse vegetables to eat.

In the previous life, that was the basic living treatment, and it is estimated that the princes and nobles can get a little bit here.

Waiting to get the glass out, it can definitely be promoted on a large scale.

The old man accepted the task with trepidation, you see the tinkling, the iron flowers splashed everywhere, the old man's face did not change, and he was really a little apprehensive when he accepted this new thing at first glance.

With the joy of being able to eat fresh vegetables in a few days, Zhao Yunrang began to think about the problem of admissions.

This is an educational pilot.

The so-called education has no class, so Zhao Yunrang didn't plan to look for it far away, and let the children run on the long road to go to school, which is inhumane.

Although it is not like the previous life, there is a risk of causing an accident at any time, but it is also a big problem to not see a person for dozens of miles.

Local materials.

The little prince set up a school in the village, and as soon as the news of wanting to recruit students in the village spread in Zhuangzi, Biluo Villa completely opened the pot.

Nothing else, I want to go to school!

And no matter how big or small, although there are no jokes that go up to ninety-nine or down to just go, but the children above the enlightenment are coming.

Reading, for these villagers, would rather go hungry than provide for their children to go to school.

What's more, Zhao Yunrang said a long time ago, it's all free!

Of course, there were some situations, some fathers and sons came over together, saying that they wanted to go to school.

There are even a few children who are indeed a little older, and the two eldest are married, and they have to regret their relatives to study.

As a result, the girl's words came from the woman, supporting Xianggong to study, you can wait.
