I really don't want to be a rebel [infrastructure]

Luo Shixing suspected that Cheng Jingwei was fooling him, adding, subtracting, multiplying and dividing ten-digit numbers, how about elementary school content?

Cheng Jingwei saw his suspicious expression and explained: "I'm serious, even in Chang'an, there are not many people who can calculate thirteen by fifteen."

Luo Shixing hesitated: "Isn't it possible? How could it be? Chang'an is the imperial capital, where almost the top talents in the country gather. How could it be possible that there are few people who can solve such a simple math problem?"

Cheng Jingwei tapped the numbers on the ground and said: "It's just that you think it's simple, not to mention that this thing is heresy, unless someone who studies this has great talent, it's hard to be an official."

Luo Shixing seemed to be the same when he thought about it. In ancient times, science seemed to be paid less attention to, but that shouldn't be the case.

The country needs to use these things, not to mention the Ministry of Industry, but the Ministry of Households, the annual population, taxation, and expenditure, don’t they all need it?

Cheng Jingwei heard his doubts and said: "It doesn't need so many people, and it doesn't need to be so sophisticated. Anyone can do this, and there is no possibility of promotion."

Luo Shixing lowered his head and thought for a while, then suddenly raised his head and said, "But I remember that the Guozijian taught this, and the imperial examination also taught arithmetic."

He has an expression of don't be an ass and me. In the Tang Dynasty, it was quite inclusive. There were various subjects. The Guozijian even set up six courses, commonly known as six studies.

It is not the six arts of a gentleman, but Guozixue, Taixue, Simenxue, Law, Calligraphy, and Mathematics. Mathematics also has a place in this dynasty.

On the contrary, from the Song Dynasty to the Ming Dynasty, the partiality gradually became apparent step by step.

In addition to Guozijian, there are Chongwenguan and Hongwenguan, both of which are teaching institutions under Guozixue, and the subjects are the same as those set by Guozijian.

Cheng Jingwei said: "It's just some mediocre children from poor families who want to get ahead and learn this."

To put it simply, the upper limit of difficulty in getting started is low, and children from poor families with some talent and ability will not choose these.

The Tang Dynasty had abundant military virtues, and the boundaries between civil servants and military generals were not very clear. If the military generals were good, they could still be prime ministers.

This has led to the fact that most people are not very proficient in arithmetic, and those who can smoothly calculate single-digit addition and subtraction are considered good.

As for Luo Shixing, Cheng Jingwei took it for granted that he was talented and intelligent. After all, he was also very talented in writing, so he was able to change his prose and write poems.

Such a person cannot be said to be mediocre, but in the end he is also very good at arithmetic, that is all-round development.

This is the case these days, if you have top grades in cultural subjects recognized by the mainstream, then if you know some other things, people will say that you are talented and knowledgeable.

But if you are not good at the main subjects, and the partial subjects are obvious, then the evaluation may not be very good, and you will not be looked down upon by others.

Luo Shixing finally figured it out, and then he brought the topic back: "Then you ask me if I know how to do magic?"

Cheng Jingwei said: "Teaching them to know numbers is easier than teaching them to write."

The pronunciation of Chinese characters is different from that of the local dialect. For children, it is bilingual education. Systematic teaching and children's intelligence may be effective. If the children are not very intelligent, the language system may be directly confused.

But numeracy is different, this thing is universal.

Luo Shixing tilted his head: "Know numbers? Will it make Ale really think that I don't take teaching seriously?"

Cheng Jing smiled slightly: "Don't worry, no matter what you teach, it's much better than him finding a local to teach."

This is a place where most of the bosses may be illiterate. Ale is really better. He is self-motivated and considered semi-literate. How could he think that Luo Shixing's teaching is not good?

Luo Shixing deeply felt that he should understand what the current teaching level was like.

But he doesn't need to be too anxious about this matter. Originally, he thought that he would start teaching the next day, but in fact there are many things waiting for him.

Because the person who built the house for them came first the next day, a muscular and muscular man, of course it is impossible for him to be tall.

It is said that because of the latitude, the overall height of people in the south will be shorter, and the height of people in places with high latitudes will be taller.

These people are all local house builders, but they haven't built the second floor and the third floor, and they don't even understand Luo Shixing's plan, so Luo Shixing needs to explain to them.

Luo Shixing felt that this was also a challenge to his knowledge reserve, and he never thought that one day he would study how to build a house!

He thought that if he drew a design, a professional would handle it, but he didn't expect the boomerang to stick on him.

Luo Shixing could only helplessly start racking his brains to study how to build such a house.

Although he and Cheng Jingwei were digging holes and laying pile foundations before, they were just making a positioning, and there were still many things to consider.

The first is the surrounding drainage. There is sufficient groundwater here, so special attention should be paid to this point.

And although their side looks like flat land, there are still certain ups and downs at the foot of the mountain. It is necessary to figure out the contour lines around the flat land, then adjust the foundation, and raise part of the foundation structure, so that the whole house can It's safer.

I didn't think about this before because they are going to build a flat floor, so there is no need to worry so much, but multi-layer, even the second floor, you need to be careful about this aspect.

The concept of contour lines was unknown to everyone present.

The problem is that this thing is still very complicated to explain, and it cannot be explained by a simple plane. In addition, he does not understand the local dialect very well, and Cheng Jingwei does not know how to use the local dialect for the nouns he speaks. Say—because the dialect doesn’t have those words at all.

These words don’t even exist in today’s Chinese, Cheng Jingwei heard it for the first time, and he didn’t understand the meaning of those words, how to translate them?

After Luo Shixing explained to Cheng Jingwei for a long time, he got a rare blank look from the other party.

He pinched one of his own people and said, "I'll talk about this issue later, let me handle it, and you will do as I said."

In this way, he couldn't leave all the house building to Cheng Jingwei, so he was still required to do it.

After all, besides a contour line, there are other things that are more complicated. If he came by himself, he might save himself a few years of life.

Otherwise, before building a house, he would have to eliminate illiteracy first, and looking at those confused eyes would not be enough to make him angry!

Now that he has been allowed to do it himself, the matter of educating the students will naturally be put aside.

But the advantage is that now he has enough hands, and some operations that he didn't dare to think of before can also be used.

For example, the construction of overhead structures.

The so-called overhead structure construction means that the structural beams come out from the ground, and then the beams are made on the columns. This is an elevated villa with a better view.

Even in this era, even if it is a little higher, the view is not good, after all, there is no glass, but Luo Shixing can build a big terrace.

Cheng Jingwei looked at Luo Shixing's rough sketch of the overhead structure on the clay board and asked a little strangely, "Is this similar to a bamboo building?"

Anyway, it was very similar to the stilted buildings he saw, after all, the floors of the houses were not in contact with the ground.

Luo Shixing nodded: "Almost, but the whole floor of the bamboo building does not touch the ground, this one still touches the ground, and this one is stronger, and the height is higher, so as long as the interior moisture-proof and the ground moisture-proof can be done well, it can alleviate the rainy season. impact."

It is basically impossible to completely remove the influence, and we can only do our best.

Cheng Jingwei looked at it seriously and said with a smile: "This can be regarded as being built according to the situation."

Although it is said that the house is in the air, it is not in the air as a whole, but part of it touches the ground according to the inclination angle of the ground, and then the height of the columns gradually increases as the ground level drops.

That is to say, the floor of the house almost forms a right triangle with the ground.

This way the ground is much better protected from rainfall and surface drainage.

However, such a structure has high requirements for load-bearing calculations, and Luo Shixing needs to measure it himself, because the calculation methods he knows use the units of later generations, and when converted into current units, there will be innumerable situations after the decimal point, which is too troublesome up.

Cheng Jingwei saw that he started measuring with a bamboo board and a rope, so he decided to do his own work first.

It wasn't his business during this, so he simply took people to dig the soil and dry it, and then made mud bricks from the soil and mud that had been dried before.

Luo Shixing tried to find a way to mark the scale on the bamboo board. The unit of meter is the best to determine, because one meter is three feet. After determining the length of one meter, he divides it into ten equal parts, and then there are decimeters. Divide it into ten equal parts and you have centimeters.

Even if the accuracy of the handmade bamboo ruler is not enough, the slight difference in the millimeter level during the construction process is basically negligible.

After getting out the bamboo ruler, Luo Shixing began to mark the ground with the cut bamboo pole.

The length and width of the house should be marked, because the slope of the ground is in the north-south direction, so there is a lot of space for columns.

Luo Shixing originally had to worry about how to calculate the weight, but when the plan was completed, he found that he didn't need to calculate it too carefully, because there are many columns responsible for bearing the weight, and the height is not high. I feel that calling the columns after finishing is a bit too much , almost called Zhuang Dun.

After confirming this point, Luo Shixing was relieved a lot. If he really asked him to calculate the load, he might die a lot of brain cells.

Especially when it comes to calculating the weight of the mud bricks and the general interior decoration, especially the multi-storey building structure is more complex, so complicated that Luo Shixing feels that it is not easy to calculate, because even if he has done the interior decoration design now, when the time comes It may not be completed either.

But thinking of mud bricks, Luo Shixing couldn't help but ran to Cheng Jingwei to have a look.

In order to be able to have a larger site for convenience and mud and try not to affect Luo Shixing to make plans.

Cheng Jingwei led the people all the way to the stream, where he cut a piece of bamboo and cleared the open space to work here.

When Luo Shixing passed by, a group of people were stepping on the mud with bare feet. It didn't look like they were here for work, but rather like a group of people happily playing with mud.

Seeing Luo Shixing approaching, Cheng Jingwei asked, "Is everything settled?"

Luo Shixing said: "Well, we need some data. Others can be discussed later. The most important thing now is to know the situation of the mud bricks. We have to wait for the first batch of mud bricks to be released to determine the specifications of the mud bricks, and then estimate The weight counts as the load.”

Luo Shixing babbled a lot, and Cheng Jingwei was dizzy, and he was sure once again that the little lynx's mathematics might not only be good, but even top-notch.

You must know that he is still young and has limited knowledge. It is impossible for King Luo Bin to teach his son spells every day. Maybe the little lynx learned these things by himself from reading books.

Thinking of this, even Cheng Jingwei couldn't help but look at Luo Shixing more. What kind of genius is this? It feels like a waste of the other party's qualifications to let him live the life of an ordinary person.

If Luo Shixing knew Cheng Jingwei's thoughts, he would definitely say with exhaustion: This belongs to the category of physics, and has some but not much relationship with mathematics.

Luo Shixing didn't know what he was thinking and continued to ask: "Are you going to make the same mud bricks as before? Will the size change?"

Cheng Jingwei came back to his senses and said with some hesitation: "Actually, I... don't really want to use mud bricks. The mud bricks are not good enough, and they can't last for a long time. Instead of repairing them again and again, it's better to directly fire the blue bricks in one step."

In the past, he thought that mud bricks were better because he and Luo Shixing had limited labor. In this case, mud bricks were the best choice.

Now that they have someone to help, why should they wrong themselves?

And since Luo Shixing became a priest, Cheng Jingwei has changed his mind. Based on Luo Shixing's identity, it is not impossible to develop from Lingnan bit by bit.

In this way, he pays great attention to his quality of life, at least the place where he lives should be safe and strong.

Luo Shixing tilted his head: "Is it too late to burn bricks?"

Cheng Jingwei explained: "Naturally, there is time. The most troublesome thing about firing bricks is drying the soil, which is just time-consuming. We have already dried a lot before, and we should be able to keep up with the use of drying soil while firing."

The soil they dug out of the cellar before was not used much, and it was suitable after natural drying.

Luo Shixing slapped his hands flatly: "Okay then, let's burn bricks."

Who wants to use mud bricks when decent bricks can be used? Let alone the ice cellar. When building a house, you may have to worry about whether the mud bricks are strong enough every time it rains.

Cheng Jing sighed slightly: "I'm afraid it won't work, no one here knows how to burn bricks."

The method of burning bricks is almost unique to the Tang Dynasty today. Of course, it is impossible for the locals to know, and Cheng Jingwei naturally does not know. When he was down and down, he couldn’t use bricks. matter?

After hearing this, Luo Shixing took it for granted and said, "It's okay, I will do this."

Cheng Jingwei:? ? ?How can you know everything?
