The shopkeeper Li only thought that he was driven crazy, and the tears couldn't stop flowing, the two of them were called master and servant, but in fact, they had been together for more than ten years, and they were already relatives, otherwise the shopkeeper Li would not have worked so hard for him: "Young master, I will definitely take you back." Let's stop doing business, let's study! ”

"Don't." Who knew that Cui Yuzhe declined his kindness, looked at the distant mountains leisurely, and said: "I just want to do my own work now, sweat my own food, live a down-to-earth life, and don't want to do the past anymore." ”

Cui Yuzhe didn't know how to explain his current state, anyway, he just felt very peaceful and peaceful now, and he didn't want any change in his heart.

No matter how the shopkeeper Li persuaded him, Cui Yuzhe insisted on his own ideas. In the end, he said that he was annoyed, he gave Li Da shopkeeper two choices, either stay and pour night incense with him, or everyone will do their own thing, the Cui family's business used to be managed by Li Da shopkeeper, and he will still be in charge of it in the future, no matter what he does, just don't disturb yourself to pick up dung.

The shopkeeper Li really couldn't understand his thoughts, so he could only look at him in a daze, only a wry smile, looking at the figure of the young master picking up the dung and going away, the shopkeeper Li clicked his lips, and suddenly he was stunned, raised his hand and touched his lips, and spit it out.

How does this get into your mouth?!

The words were divided into two ends, and Li Mu and the others came to the cement field at the foot of the mountain.

I saw that around the cement yard, the wall of one zhang has almost risen, and looking at the progress of this project, it will not take three days to complete. I saw that at the root of the wall, I don't know when, a bunch of thistles were prepared, and it seemed that they were going to be inlaid on the wall.

"So exaggerated?" Li Mu was a little surprised, he called Yu Wengui, who was in charge of the project, over to ask, but Yu Wengui took the trouble and said, "There is a core secret of cement here, Master Hou." ”

I saw him speak righteously: "Not everyone in the world is honest and trustworthy like Lord Hou, and there are more despicable villains." You can't have the heart to harm others, and you can't do without the heart to defend people. How many pairs of eyes are staring at our cement factory every day, how can we do it if we don't pay attention to it? ”

"There's no need, just learn to go." Zhao Gongzi said indifferently: "I'm afraid that they will 'draw a tiger and not become an anti-dog', learn to go half-way, cultivate tofu scum, not to mention the scourge of the people, and ruin the reputation of cement." ”

That's what he said, but Li Mu also thought so in his heart, good things are still good that they have, and technical barriers must exist for a while. Not to mention the aspect of interests, if people learn the formula of cement, their plans can be completely disrupted.

If you build a concrete fortress, with the black powder you currently have in your hands, you really can't open it. Although this is a little farther, there is really no need to put obstacles in the way of your future.

He pondered for a moment, and finally said cautiously from the heart: "Then let's keep it secret first." ”

The heavy cement yard gate slowly opened, and rows of gray factories appeared in front of him, with three tall chimneys erected, forming a strong contrast with the surrounding bright mountains and beautiful waters. Sun Fujia was stunned, pointed to the three chimneys and asked, "What is this?" ”

"Chimneys, for exhausting, are used to make cement." Li Mu didn't explain much, but he was very excited in his heart, if there is an iconic image of the industrial revolution, trains and chimneys must be the two most voted options.

Think about the Industrial Revolution, what factory could be separated from the chimney?

This is a sign of bidding farewell to the era of agriculture and opening up modern civilization!

Holding back the excitement in his heart, Li Mu put on a thick mask.

Yuwengui and the others also hurriedly followed suit, Sun Fujia didn't have a mask, he was a little dazed, Yuwengui handed him a mask, and he also put it on his mouth.

At the beginning of the construction of the cement yard, Li Mu set the rule that everyone who comes into direct contact with cement must wear a mask. Although the workers felt that this was not necessary, and they had been wearing masks for a long time, and they were still a little panicked, but Li Mu made it mandatory, and everyone had no choice but to obey orders without understanding.

Who made this rule linked to their wages? If you don't bring it once, you will deduct half a month's salary, and if you don't bring it twice, you will go home directly. Lantian County can't find a place with better treatment than here, unless it's a fool, no one really cares about this.

~~

The whole mountain is made of limestone, and the so-called factory is actually just a wall built around the entire Wonsan.

In the mountains, there are limestone mines.

Workers crush the quarried limestone and transport it to the bottom of the mountain, where there is a crushing workshop for the next step of crushing. Since the progress of the industrial revolution has not yet arrived, Li Mu can't come up with a machine to crush stones now, and the crushing process is still mainly manual.

Workers take turns with sledgehammers and smash the limestone into fist-sized pieces. It is then sifted through a sieve, leaving the lime powder behind, and the remaining lime blocks are sent to the milling workshop next door. And so on, and the stones become powdery. Limestone is not a very hard stone, and the process is relatively less strenuous.

The mill is a large long factory with hundreds of stone mills, and the workers are bare-chested, sweating like rain, grinding lime blocks into powder.

There is a sieve with a sieve surface under the grinding disc, and only the lime powder that can pass through the sieve is suitable, and the grinding must continue if it does not pass. This is also the most time-consuming and laborious part of the entire production process, but it is also a critical step, and the requirements cannot be relaxed.

When the material is delivered, there is a special quality inspector to check to prevent someone from fooling.

The whole grinding room was grinding limestone, and no other raw materials were seen. Li Muwei Sun Fujia introduced: "Up to this point, all the processes are still limestone, and the other two main ingredients, gypsum and kaolin, are processed elsewhere. It is used by another group of workers to prevent leaks. All the raw materials are processed and will be transported to a special proportioning factory, and I also specially arrange people to prepare some irrelevant powders, and the personnel are also mixed, making it difficult for people to find out the truth and the truth, so that I can do my best to reduce the possibility of leakage.

"Cunning." Sun Fujia said secretly in his heart, but he said: "It should be, it should be, it's better to be cautious." ”

In fact, Li Mu was not too worried about leaking secrets.

After all, firing cement is a very scientific thing, and it is useless to know the formula, and the key to its production lies in temperature and correct raw material ratio.

If these two things are not done well, the quality of the burned cement will be very poor, and even the building will collapse on its own.

Since the birth of cement 200 years ago, human beings have found the so-called best ratio of cement and the most suitable temperature. It is difficult to do both without the other.

The former is good to say, after all, all links are done by people, if a certain gate valve family, if you really want to know the raw materials, carefully investigate, buy, you must be able to know.

But the temperature can't be helped, and there is no thermometer in this era.

For this problem, Li Mu really thought about it for several nights, and in the end, he really found a local solution for him.

Firelight.

The flame that first glows is 500 degrees, 600 degrees crimson, 700 degrees red, 800 degrees cherry red, and 1,000 degrees cherry......

When the fire is white-hot and people dare not look at it directly, it reaches 1,400 degrees!

In the end, what kind of fire color should be maintained in the furnace, except for Li Mu himself, only Li Mu and several employees in charge of this matter know, but they don't know why, they know that this is right, which makes it difficult for others to steal secrets.

Moreover, the color of the fire should be kept white-hot, that is, 1,400 degrees, coal and coke alone are completely insufficient, and firewood is not at all.

Fortunately, there is coal here, and the coal can be crushed and burned, which can increase the temperature. But even then, it's still a little bit close, and the easiest way is to buy a catalyst from the system store, but that would be too costly, so it's better to use corn mortar.

These days, in addition to dealing with the remaining problems, Li Mu spends most of his time thinking about raising the furnace temperature.

He searched through almost all the drawings in the system and finally found a solution. First, a high kiln with automatic suction was built, and several air tanks were constantly pulled to let the fuel burn again, and finally the furnace temperature was reached.

And the refractory bricks used to build this furnace are made of kaolin. It is very convenient to get the moon first near the water.

The bricks fired from ordinary clay elsewhere simply cannot withstand the temperature in the high kiln......

……

After visiting the cement yard, Li Mu's hair was already gray, and the others were not going anywhere. Only then did Sun Fujia understand why Li Mu insisted on wearing a mask, if he didn't wear a mask, he would have to fly into his mouth.

Sun Fujia was still unsatisfied and wanted to stay for a while, but Li Muke was about to get off work, and the rule he set for himself was that he would work no more than four hours a day.

Sun Fujia had no choice but to come out with Li Mu.

On the way back, Li Mu took a look at the dormitories of these employees.

And it's been a big change.

The original dilapidated wooden house was completely demolished and rebuilt into a new brick house, with white plaster on the outside, black tiles on the walls, cement on the yard, and the wellhead sealed to prevent dust from falling in.

Sun Fujia did not return to Chang'an today, Li Mu asked him to go back to the city to live, but he had to stay in the cement factory for a day. And the shopkeeper Li didn't say anything about his family's young master, so naturally he wanted to stay. Li Mu didn't force it, anyway, the secret recipe was in his head, and he didn't say that no one could take him.

Wei Yingluo has always been by Li Mu's side, of course she knows how dirty the cement yard is. Li Mu went to the factory today, so she wisely didn't go with her, and came directly to clean up the residence, boil the water and wait for Li Mu to come back.

Seeing that he really entered the yard with a disgraced face, Wei Yingluo teased him while helping him wash his hair and take a bath.

After Li Mu freshened up, it was already dark.

Li Mu asked someone to send a table of noodles over, and Quan Dang invited Sun Fujia to dinner.

He was going to ask the shopkeeper Li what he had talked about with Cui Yuzhe, but he thought that it would affect his appetite too much, so he wisely didn't speak.

The heart said that this guy would definitely ask for himself anyway, and he would talk about it when the time came.

——

At night, the quarry finally quieted down, and it was not suitable to quarry at night, because the stones were too big to dodge, and it was easy to hit people.

From here to the grinding workshop at the foot of the mountain, they still have to work overtime. There are those who carry stones, and there are those who smash stones.

Overtime is paid for overtime, so the workers are very happy. The workers alone can't do it, and the nearby villagers, as long as they have a car and livestock at home, can come and earn some extra money.

Old Song and his son waited until this moment before it was their turn to drive the ox cart forward.

At this time, the steward of the quarry asked them to show their red heads.

It was the one they received from the steward at the foot of the mountain when they came, and it had a unique number on it.

The steward lit the torch, wrote down the number, and then stamped it on it, handed it back to Lao Song, and gave him two meal tickets, relying on this, he could receive steamed buns tomorrow.

The steward shouted: "Six baskets! ”

So the man carried the stones in the basket to the chariot of the two men, and after a total of six baskets, he stopped.

The old cow snorted, it's okay, I can't help it.

"Hurry up and get out of the way." The steward waved his hand and told them to leave quickly.

The two of them will drive the cattle carefully, whatever you think. Cui Yuzheyun said lightly: "But I can tell you that no one is persecuting me, I do think so." He pointed to the person working opposite, asked the shopkeeper Li, and said, "Look at them, what do you feel?" ”

The shopkeeper Li was stunned: "A group of Liba, what can you feel?" Master, what's wrong with you? ”

"There is no Huigen!" Cui Yuzhe shook his head, with a pity expression, and said: "But also, everyone has Huigen, and there are no fools in this world." Let me tell you, these people are hard-working people. They work for a day, receive a day's wages, take the wages home, and feed their wives and children, how valuable they are! ”

As he spoke, he continued; "The original me has no value. I'm like a moth, but now I'm worth it, you see. The whole factory, you can't play without me! ”

The shopkeeper Li was completely stunned, what kind of work is pouring night incense, you can't play without you - it really seems to be the case, no one pours night incense, defecating everywhere, how smelly it is, it's right to understand it this way.

But there is still a lot of business waiting to be dealt with at home, and it is not a problem to pour night incense here!

Whatever you want. Cui Yuzheyun said lightly: "But I can tell you that no one is persecuting me, I do think so." He pointed to the person working opposite, asked the shopkeeper Li, and said, "Look at them, what do you feel?" ”

The shopkeeper Li was stunned: "A group of Liba, what can you feel?" Master, what's wrong with you? ”

"There is no Huigen!" Cui Yuzhe shook his head, with a pity expression, and said: "But also, everyone has Huigen, and there are no fools in this world." Let me tell you, these people are hard-working people. They work for a day, receive a day's wages, take the wages home, and feed their wives and children, how valuable they are! ”

As he spoke, he continued; "The original me, just
