As a salted fish, I was forced to become the teacher of all ages

After the two got up, Hua Manlou said in a daze: "Fang Erniu... I seem to have a little impression of you. My Xishanbo Mansion was the backyard you led to repair?"

Fang Erniu didn't speak, but the woman was flattered, and then glared at the man again.

Hua Manlou wondered, "So...you two, which one are you singing today?"

"Your society still looks like a front society?" The woman glared at the man.

"Oh, let's do it." The man said with a wry smile, "Uncle, there are some... things I want to give to you."

Hua Manlou was even more puzzled: "This has something to do with the two of you fighting...cough, quarreling?"

"Yes, we seem to be arguing over this thing." Fang Erniu smiled bitterly, took out a paper bag from his arms and handed it to Huamanlou with both hands: "Originally, I seemed to want to study well in the society, but now Auntie is in a hurry..."

Hua Manlou took the paper bag in a daze, and felt his hand sinking: "This is?"

Before Fang Erniu could explain, Hua Manlou who opened the paper bag was stunned: "I'll fuck it!"

531.

The things in the paper bag are very familiar. In Huamanlou's previous life, almost everyone in the Celestial Dynasty recognized it... Well, it's better to say that after seeing this thing, the talent of infrastructure madness in the blood will start to roar, and Huamanlou will be in a trance. I even saw four words: Cover for Lao Tzu!

This thing is cement, dear!

Da Zhao, who doesn't know how far away from the technology of his previous life, and who has deviated from the historical track after the Three Kingdoms, actually saw cement, so one can imagine how shocked Huamanlou was.

Of course, there is still a gap between this cement and the cement in the previous life, not only the color is different, but also the shape is rough, but there is no doubt that this thing is cement!

To be honest, Huamanlou wanted to make cement a long time ago, but he didn't know how to make cement. Of course, he still understands that ordinary cement is also called Portland cement. Its strength is not high. It is calcium silicate, which is mostly used in building houses in rural areas, but in this world, where can he get calcium silicate?

Speaking of time-traveling novels, the method of making cement is often mentioned, and he also vaguely remembers that cement seems to use limestone and clay, which are basically everywhere, but the problem is, who knows the main ingredients can get the finished product ?

We don’t need to mention things like Yunnan Baiyao, let’s take ordinary food as an example: logically speaking, if you have eaten a certain dish, you know how it tastes and know its main ingredients, you can roughly understand the dish, but If there is no large-scale experiment, who can make a dish like a super chef without fumbling?

What?

You said that you slowly experiment after knowing that there are limestone and clay?

Having said that, can you expect a salty fish like Huamanlou to grind limestone and clay all day long?

So at some point, Hua Manlou really wished that he had studied civil engineering in his previous life, or maybe bridge construction, at least these were related to infrastructure, right? (Come on, give a round of applause to the students of the Department of Civil Engineering)

But now, a plasterer delivered cement to him.

Well, Fang Erniu's profession should be called an ancient type of civil engineering. How ugly is a plasterer or something!

Seeing Hua Manlou's horrified face, Fang Erniu was even more horrified than Hua Manlou: "Uncle... Uncle knows this thing?"

Hua Manlou was taken aback, neither admitted nor denied, and finally could only cough dryly: "It doesn't matter whether I recognize it or not, the important thing is, what did you build this thing for?"

Fang Erniu's complexion became even more bitter. He glanced at Fang Lin's, but the woman stared straight away: "What?"

It has to be said that Hua Manlou has always been a little in awe of Lao Shan, because he thinks that the Guanzhong people on the Loess Plateau are stronger than the legendary Guandong people.

Because, anyone who knows a bit of history knows that in the Tang Dynasty, it was just such a group of unpretentious, unassuming, and ruthless Guanzhong men who trained the neighboring countries one by one, and in terms of their daily style, they were too steely—— Look at this woman, her word "呵" is very spiritual, because people in Guanzhong are like this. Compared with "what are you looking at" and "what are you looking at", a single "呵" can solve many problems...

Do not believe?

If you don't believe me, why don't you reply with a more powerful word?

Anyway, Hua Manlou's heart shrank with fright, and Fang Erniu also trembled: "Back to Uncle, I don't know what this thing is used for, maybe it can be used for building houses and roads..."

Huamanlou is really admired: it is indeed an ancient species of civil engineering!

Under Fang Erniu's stumbling explanation, Hua Manlou gradually figured out the origin of the cement and the story of Fang Erniu and his wife.

Their past is actually very similar to the past of many craftsmen who came to Xishan.

These days, there are many people who rely on crafts to make a living. As far as life is concerned, it is not a problem for them to barely eat enough, but if they want to live a better life, it is difficult, no matter if they are blacksmiths, masons, and plasterers.

That is to say, they can't starve to death, but their ability to resist risks is very poor.If they didn't encounter any major incidents, they would generally be able to live a safe life after stumbling, but if something happened...

This is the case with Fang Erniu. After he married the pungent Fang Lin seven years ago, the two soon had their first child.

Originally their life was not very good, but it was considered peaceful, but four years ago their son suddenly fell ill with a strange disease, after seeking medical treatment everywhere, Fang Erniu gritted his teeth and sold all his family property, intending to come to the capital to try his luck.

Unfamiliar with the place and lost their source of income, the family soon fell into a predicament. In the end, their children could not be kept, and they could not even afford to eat.

And just when the couple were desperate and living on the streets, they happened to meet a wave of young soldiers who went to the capital to recruit artisans, and they were taken to Xishan to settle down in this way. At that time, it was the first expansion of Xishan. A year and a half ago.

Therefore, it is not an exaggeration to say that Fang Erniu and his wife were both rescued by Huamanlou.

Both of them are honest Lao Shan, who felt that they owed Huamanlou a lot, and the more they owed—because they paid for their expenses in Xishan at the beginning, and Fang Erniu’s wife, after her second pregnancy, became pregnant. The baby in the picture was delivered by Wan Qiyanran.

Seeing that the days are passing and there is more hope, Fang Erniu is grateful, but he doesn't know what he can do for Huamanlou. Even if he helped Huamanlou build a house, he feels that he cannot repay Huamanlou's kindness.

So originally this gratitude could only be kept in the bottom of his heart, and he would rush to Huamanlou when he was in need. But just a few days ago, he accidentally discovered something: limestone, clay mixed with some cinders and iron After the ore slag, it miraculously bonded together, very firm.

Fang Erniu, who was born as a plasterer, immediately realized that this thing could be used as a building material, so he immediately started to study it—Xishan’s way of thinking really affects everyone in Xishan, and everyone wants to make something in their own field. Of course, Fang Erniu is no exception.

But the problem is that, as Huamanlou expected, even knowing some main materials, it is still somewhat difficult to research the finished product, which requires a lot of experiments.As for Fang Erniu, he was obviously incapable of tossing around by himself, but he was a serious and stubborn person, so he kept investing in it, only to be discovered by Fang Lin.

Fang Lin didn't stop his research, but felt that if he had any results, he should report it to Huamanlou immediately, but Fang Erniu felt that his research and development was half-baked, so the two of them quarreled, and the more they quarreled, the more fierce they became. As a result, the irritable Fang Lin thinks that Fang Erniu is ungrateful and wants to steal the secret recipe for himself instead of repaying his kindness...

So Fang Erniu was beaten up.

Afterwards, things got more and more outrageous, and Fang Erniu was so stupid that he couldn't persuade Fang Linshi. The two of them quarreled again early this morning. Hua ManLou wants him to kowtow to Hua ManLou to make amends...

532. Very dreamy

After listening to Fang Erniu's words, Hua Manlou glanced nervously at Fang Lin who was still glaring at Fang Erniu: "I won't accept this thing... Oh, don't get me wrong, this thing is really big. Use it, but this is your own hard work, I can't just accept it like this."

Seeing that Fang Erniu wanted to say something, Hua Manlou waved his hands and said, "Listen to me first, okay?"

Seeing the honest man nodded, Hua Manlou said: "To be honest, I actually understand a little bit about the thing you developed. I wanted to make this thing before, but firstly I was too busy, secondly I I don’t know much, so I think it’s better for you to study this thing, well, I’ll pay for it, and you contribute, how about it?”

"This..." Fang Erniu panicked: "Uncle, I don't dare to...it doesn't seem like that's the only thing I can take out..."

This honest man is really a bit hopeless, he doesn't even think about making money with cement - of course, he doesn't know how much this thing is worth, but this does not prevent him from wanting to make money from this seemingly impossible The things on the table are dedicated to Huamanlou.

"Just do what I say." Hua Manlou interrupted him directly: "According to Xishan's rules, I will build a laboratory for you. After the things are fully developed, it will be yours or yours."

Fang Erniu was so cramped that he was out of shape, and he turned his eyes to Fang Lin's for help.

Fang Lin also looked at Huamanlou anxiously: "Uncle, he... he is like a mason, his crooked work is just a bit of dirt..."

After staying in Xishan for a long time, everyone knows how glorious it is to establish a personal laboratory, because after the establishment of the laboratory, if the future experimental results are profitable, Huamanlou will get [-]% of the net income, Xishan will get [-]%, and the rest They are all in the laboratory, and the lead researcher gets the big head—this is the rule set by Huamanlou after the establishment of the university. Why don't everyone rush to the firearms research and development class?

It can be said that Huamanlou's rules are really too kind, not to mention these years, it was in Huamanlou's previous life, whoever investor you are looking for should not take the lead?

So both of them were frightened: it's just a pile of worthless soil, how can they be treated like this?

Hua Manlou looked at the simple and honest couple, and comforted him, "What's wrong with the soil? Who doesn't need some soil? Let me just say it. Although the thing that Er Niu studied seems worthless, it is worth enough for him. The name goes down in history, so..."

Hua Manlou doesn't think he's exaggerating, because with the blood of the infrastructure madman of the Celestial Dynasty, the person who made the cement will be remembered by everyone.

belch……

Fang Erniu almost pulled over directly: "Famous... famous in history? No way, uh... uh, like a plasterer who can't read..."

It was only then that Hua Manlou realized that his expression could easily scare people. After all, Er Niu was a small person, and the biggest official he had ever met before coming to Xishan was the head of their village—in reality, most people really don’t see him The level of the county magistrate, so it is a bit nonsense to say that the name of a small person like him is true in history.

So he said: "Er Niu, let me just say this, you don't need to worry about the other things, as long as the cement... oh, it will be the greatest help for me to build this thing you made as soon as possible."

"Really...really?" Fang Erniu instantly came back to his senses.

"Yeah, really." Hua Manlou said: "I can give you some advice, for example, the things you use to mix cement need to be finely ground... Well, I will go to the foundry class to process a pair of hydraulically driven heavy weights for you. Mo, what you have to do is to figure out the best ratio of these things you mentioned."

Fang Erniu was dizzy again in an instant: "The best ratio is sprinkle?"

"Uh..." Hua Manlou thought for a while before smiling wryly, "You have to find a way to make the best cement, the strongest, the strongest, the most...you know what I mean?"

"Oh, I understand."

"Just understand." Hua Manlou wiped the sweat from his forehead, and continued: "From my point of view, the thing you made not only needs to be ground and proportioned, but also needs to be fired like a brick. Burn it, and finally mix sand and soil with the best..."

Hua Manlou vaguely remembered that there were several ways to make cement in his previous life, one was grinding and mixing raw materials, and the other was firing in a shaft kiln, so he explained all of them, anyway, that's all he knows, Let him do it himself...

Oh, what a joke, Mr. Hua is busy!

Although Fang Erniu didn't understand half of what he heard, he still listened carefully and memorized it, and signaled Fang Linshi to memorize it with his eyes.

I have to say that people with a single mind have such an advantage. They may be clumsy, but once they stubbornly grasp a right thing to do, one day you will suddenly find that what they are holding is already Many people need something to look up to, and Fang Erniu is such a person.

After Hua Manlou finished talking with him, the Fang family couple left in a daze, and...

That afternoon, Liu Fan, Huamanlou's loyal dog leg, came to the door in person, and took the man who was beaten by his wife, who was on the hot search in Xishan, to a laboratory near the river in the University of Science and Technology, and respectfully offered him A strange piece of clothing—this is the standard configuration for the dean of Xishan University. It looks like a cloak, with a complicated pattern on the back and four large characters written on it: civil engineering.

That's right, this is another trick Hua Manlou did when he had nothing to do. Is this the style of the cloak...

Anyway, people who have seen the god of death are not very unfamiliar.

In short, since today, Fang Erniu has changed from a plasterer to the dean of the School of Civil Engineering of Royal Institute of Technology, although according to Liu Fan, he is now just a poor commander, and even the school has to be built by himself. He even had to recruit apprentices himself, but...

No one laughed at the fact that Fang Erniu was beaten by his wife, and no one mocked him as a coward, because the dean of the University of Science and Technology itself represents the highest glory of Xishan, and none of these deans is not a red man beside Hua Manlou. people……

……

"What a surprise."

After sending Fang Erniu away, Hua Manlou still felt very dreamy: I really want to do whatever I want?

Ever since he knew that Zhao Ren was tinkering with the carriage, he had vaguely felt that the cement had to be made to match it. Only a few days after this idea came up, a plasterer suddenly appeared to offer cement, so...

Did you think about rubber, and suddenly someone came across the ocean to find you with rubber in a few days?

No, I don’t dare to think about rubber for the time being, but I can always think about corn, potatoes and peppers, right?

Especially chili, Huamanlou has been wanting to eat hot pot for a long time, but there is no chili these days, the only similar condiment is Temo Zhuyu, that thing...

"So, did the Europeans go to America to explore?" Hua Manlou looked at the sky, with a gloomy expression on his face, "Supposedly this group of people should also be in line with the Celestial Empire, so why hasn't there been any movement for so long? "

533. You Better Stop Talking

Contrary to Hua Manlou's expectation, the cement soon took a look.

I don't know whether it was out of sympathy for Fang Erniu who was beaten by his wife or because he was very interested in what he was researching. The people in the casting class almost built an experimental iron mill for Fang Erniu at the fastest speed Immediately, Fang Erniu began to experiment with various cement ratios using the method Huamanlou said.

Having said that, I have to ask a very serious question: quantification.

I don’t know if it’s because the people of the Celestial Dynasty are smarter or because the people of the Celestial Dynasty lack such things as rigor, which makes it easy for many projects to encounter problems caused by quantitative units—this is not nonsense, after all, you Look, when some important technologies are recorded in many ancient books, most of them do not record too detailed data. This situation continued until the appearance of Song Yingxing's "Tiangong Kaiwu" and it was gradually improved.

For example, "Nai Li" pointed out that rice seedlings were uprooted and planted separately 30 days after seedlings were raised, and 25 acres of seedling fields could be transplanted, that is, the ratio of seedling fields to Honda fields was 1:25.It is also said that there are three buckets of water for upland rice and five buckets of water for late rice. If you lose water, you will dry up. This important data-based thing has never been mentioned in previous agricultural books.

And, the problem of quantification has developed with the times, and it has reached the era of Hua Manlou's previous life...

Well, in that era, some areas were still not fully dealt with, it was all based on feelings-look, how many people who read recipes and cooks have been driven crazy by the description of half a teaspoon of salt, a little fennel, and half a bowl of cold water?How many crooked nuts did you drive crazy?

In short, without strict and detailed data support, many jobs can only be done based on experience. After the experienced people die, the craft will be lost.

Therefore, Huamanlou has strictly required data recording and data unification since the beginning of making firecrackers. This is especially evident in the subsequent firearms research and development classes and alloy research and development classes—someone once planned to use 'iron ore "Two catties" and "a handful of unknown ore" were played in such a style, but Huamanlou sprayed them almost to the point of autism...

What's more, Huamanlou also forced all R&D personnel to go to the Department of Mathematics for advanced studies, and even thoroughly popularized the more useful Arabic numerals.Although Qiaoqiao, the Department of Mathematics, is still playing with four mixed operations and the Pythagorean Theorem, it is still ahead of the times, right?

Therefore, after quantifying this kind of thing in cement manufacturing, it really provided Fang Erniu with a lot of convenience - he used to only know limestone, clay with a small amount of iron ore and coal, after Hua Manlou enlightened him These four materials are made into finished products according to different ratios, and then labeling, experimentation, and archiving are completed in one go, and you have completely become a qualified research and development personnel.

Not only that, the quantitative indicators also gave Fang Erniu some inspiration in the experiment. For example, when testing the strength of different finished products, he used a ten-pound hammer to make it from one foot, three feet, and five feet respectively. Drop it on a concrete slab and see how it breaks.

When a stubborn person encounters something that needs to be stubborn, the chemical reaction produced is simply jaw-dropping—after a period of sleepless research, Fang Erniu finally took out a qualified test product and handed it to Huamanlou .

Although it looks a little different from the cement in the previous life, in Hua Manlou's opinion, it is almost usable, after all...

In any case, you can't make Portland cement with the label 325 in this era when technology has just begun to develop, right?

……

"This is……"

Zhao Ren, who was developing a four-wheeled carriage with his head covered, was dragged to the Civil Engineering College by Hua Manlou. What he saw was a group of people mixing gray powder and sand together, and the scene was in a hurry.

Hua Manlou said with a smile, "I'll show you a fun one, the art of turning sand into stone."

"What?" Zhao Ren looked at Hua Manlou with an expression like you were teasing me: "Are you serious?"

"Seriously." Huamanlou pointed to Fang Erniu, who had already leveled a piece of land and was laying wooden frames at the corners, and said, "Here, did you see that, that person invented it."

Originally, Zhao Ren was a little dissatisfied when Hua Manlou dragged him from the test site, but seeing that Hua Manlou didn't seem to be joking, he also became interested: "Turn sand into stone... wait a minute, you want to use this thing?" paving?"
