Peek at my diary, Cao Cao dominates the Three Kingdoms

With cement, you can quickly pave a solid road; with cement, you can build a strong city in the grassland!

Just when Lu Yan was dreaming about the concrete cities that would rise one after another in the future, Liu Bei and Zhuge Liang finally arrived hand in hand.

Seeing the closeness of these two people, a smile appeared on the corner of Lu Yan's mouth, and he thought: "Fish and water have finally met... But now, they are all in the pond of me and Lao Cao!"

Both Liu Bei and Zhuge Liang are people with great etiquette. When they saw Lu Yan, they immediately stepped forward, bowed and said, "I've seen you sir!"

"Xuande, Kong Ming, you are here!" Lu Yan helped them up, pointed at the black pile of powder behind him and said, "Come, let's take a look at the freshly baked goodies together!"

Liu Bei and Zhuge Liang looked around and found that the "good stuff" that Lu Yan referred to was just a pile of powder...

"What is this for?" Liu Bei asked after looking around curiously.

Although Zhuge Liang didn't ask any questions, his bright eyes couldn't hide his curiosity anymore.

"Try it right away and you will understand." After Lu Yan replied with a smile, he said to the craftsmen: "Come and experiment with cement."

However, after Lu Yan's order was issued, the craftsmen looked at each other with hesitation in their eyes.

Lu Yan saw the doubts of the craftsmen, so he asked, "What's wrong? Have you encountered any problems?"

The craftsmen were a little afraid to speak, and looked at their boss, Geng Liang.

Geng Liang led Lu Yan to another experiment place, and said, "Lu Huqi, in fact, we have been experimenting before..."

When he arrived at the location, Lu Yan saw that a large pile of cement powder had been piled up under a wall in front of him.

Moreover, on that wall, there was a paste made by mixing cement powder and water according to the method Lu Yan said before, and pasted it on the wall.

Geng Liang stepped forward and stretched out his hand to gently break the wall. With little force, he broke off a large piece of cement.

Not only that, after he kneaded it in his hands for a while, the cement blocks turned into tiny lumps and scattered down, "Look, Lu Huanqi, this cement doesn't seem to be strong..."

After Geng Liang demonstrated, the craftsmen all lowered their heads in shame.

It has been more than half a year, and they have not developed the kind of cement that is as hard as a stone that Lu Yan said, which makes the artisans who receive generous salaries feel guilty.

Lu Yan stepped forward to observe carefully, then suddenly laughed and said, "I don't blame you, I didn't make it clear."

"Huh?" The craftsmen raised their heads and looked at Lu Yan.

Geng Liang asked, "Is there any process missing?"

"It's true that there is still a process missing." After Lu Yan finished speaking, he asked the craftsmen around him: "Is there any river sand? Go find some."

Hearing the river sand, some craftsmen immediately shouted: "There are some! The little ones are brought here!"

Before the others could react, the craftsman had already galloped away.This made the two companions around him feel annoyed, "Damn it, he was one step ahead!"

The craftsman was strong and strong, and he came over with a bag full of river sand.

After finding the sand from the river, Lu Yan asked craftsmen to mix the sand into the cement, and then add water to stir it.

After the cement and sand were completely mixed, Lu Yan asked the craftsmen to put the cement on the wall again and let people dry it with fire.

After drying and waiting for a while, Lu Yan said to Geng Liang: "Old Geng, try again."

If cement is mixed with sand, the strength after drying is really not good.But once sand is mixed in, the strength will change instantly, not to mention stone, it is even harder than some ironware at this time.

Geng Liang stepped forward, and first broke it with his hands as before.

But with this force, I immediately felt the difference in the cement, "It's so hard! I'm still panicking!"

Geng Liang was overjoyed, and said to the craftsman, "Bring the shovel!"

A craftsman handed over the shovel used for mixing cement, and after Geng Liang took it, he said "Keng Keng Keng!" to the wall.

"This thing actually made a sound of metal and iron!" Zhuge Liang and Liu Bei's eyes widened suddenly, and they murmured in disbelief.

It is actually not good to quickly dry the cement. After it dries, there are still some cracks on the surface, and the strength is lower than that of natural drying.

But even so, Geng Liang was sweating profusely, and only scraped off a small layer of sand. Not only Liu Bei and Zhuge Liang, but even the craftsmen who were used to seeing new things were shocked at this time.

"This... this thing is too amazing!"

"That's right, the cement becomes so hard just after being mixed with sand, it's really amazing!"

"Unbelievable, unbelievable!"

Listening to the emotions of these people, Lu Yan thought to himself: "There are more beautiful ones waiting for you!"

So, Lu Yan ordered the craftsmen to make a mold with wooden strips, poured cement into it and added iron rods to cast a cement board about three inches thick.

After waiting to be dried by the fire, Lu Yan ordered the craftsmen to smash it with a hammer.

The two craftsmen groaned and smashed for a long time. Although the cement slabs were broken, but because of the connection effect of the iron rods, it couldn't be broken or smashed completely.

After the craftsman was exhausted and out of breath, Liu Bei stepped forward and stepped on the dilapidated cement slab, saying with emotion: "What a hard cement slab!"

And Zhuge Liang obviously turned his mind faster, he had already thought of the magical effect of this cement: "Sir, with cement, our city will become stronger!"

Liu Bei, Geng Liang and others were stunned, and then complimented Lu Yan one after another.

However, Lu Yan said with a smile: "The magical function of this thing is not just to strengthen the wall!"

Chapter 438 "Ambition"!

If you don't pursue too high quality, cement is actually very simple to make.

But there is another problem, how to crush those ore materials... Thinking about it at this time, if you only rely on purely manual materials to crush the materials, the efficiency will be really impressive.

Fortunately, the hydraulic bellows have already been made, and now they only need to be modified to crush materials.When the time comes to build a cement plant by the Yellow River, the problem of power will not be a problem.

To say that the strongest part of cement is actually after mixing gravel into concrete.

Think about the scene of pouring reinforced concrete in modern buildings, it can be poured into any shape you want.

Whether it is a rectangle, a triangle or a cylinder, you only need to build a mold and put steel bars inside, and then any shape can be poured out, and it is extremely strong after it is formed and dried.

In modern warfare, as long as you look at the bridge decks that have been blasted out of the holes by shells, you can clearly feel the strength of reinforced concrete.

Ordinary red bricks are most useful for building houses quickly.

Coupled with the fire resistance of red brick itself, building houses with it is not only fast and strong, but also can resist fire to a certain extent.

After the cement is successfully made, the next step is to experiment with the combination of red bricks and cement.

Under Lu Yan's explanation and personal demonstration, several plasterers who are good at building quickly learned to build one layer of cement and one layer of bricks.

Under the astonished eyes of everyone, it took only half an hour for four plasterers to build a wall that was as tall as a person and more than ten feet wide.

The point is, the speed is high, and the quality is still good, which makes everyone present a little excited.

"With cement and red bricks, it will be much faster to build a house in the future!"

Geng Liang felt a lot of emotion, and it seemed that he had some resentment towards building the house.

There is no way, the general supervisor is now a steel factory and a shipyard, and now there is a cement factory coming, the demand for craftsmen is too great.

After the craftsmen came to Chenliu, their families needed a place to settle.

In the past, traditional wooden houses were built. Not to mention the time-consuming and labor-intensive construction, the quality is not necessarily good.

Now that there are cement and red bricks, won't building a house in the future be a matter of sprinkling water?

Zhuge Liang also thought of using cement to strengthen the city wall; Liu Bei thought of using cement to build roads.

It has to be said that the wisdom of the people is infinite.Lu Yan didn't need to remind too much at all, most of the functions of cement had already been excavated by them.

But after all, they missed a function that can be called a plug-in level, and that is "fortification!"

To be precise, it is to build a city wall.

With a steel factory with a daily output of [-] jin of steel, there will be no shortage of steel bars in the last two years.

When building the city wall, after setting up a mold for a section of the city wall, and then pouring it with concrete, the efficiency is simply heaven-defying!

As long as there are enough materials, a strong city can be built on the ground in half a month.

At that time, clean and solid cities will suddenly spring up on the grassland one after another, and those grassland people will probably be scared to death.

......

"Brother Xuande." Lu Yan suddenly shouted to Liu Bei who was squatting on the ground and carefully observing the wall.

Liu Bei stood up, ran to Lu Yan in small steps, cupped his hands and said, "Sir, what's your order?"

"I will leave the construction of the cement plant to you. Whether you supervise it yourself or assign people, I only have two requirements, efficiency! Keep it secret!"

Liu Bei's face turned serious, and he bowed to salute and said, "Beidin will personally supervise such an important matter. If there is any mistake, I'll come and see you!"

After all, he used to be a warrior. After receiving the important task assigned by Lu Yan, Liu Bei issued a military order without even thinking about it.

Lu Yan looked around and said to everyone present: "Cement is a top secret, and its level of secrecy is not lower than that of battleships and artillery. Anyone who leaks the secret will be severely punished!"

The craftsmen have long been used to all kinds of top-secret information, and they basically don't leave the area of ​​the prison, so the secrecy is pretty good.

What Lu Yan mainly warned was those officials. If they are not kept together, some of these officials will be corrupted by money or beauties because of their unsteady thinking.

"Your subordinates obey!" Liu Bei, Zhuge Liang, including Geng Liang and other officials and petty officials, all saluted very solemnly.

After the cement experiment came to an end, Lu Yan, Liu Bei, and Zhuge Liang left the general prison.

When he reached the empty official road, Lu Yan suddenly reined in his horse and stopped.

Seeing this, Liu Bei and Zhuge Liang also stopped.

At this time, Lu Yan suddenly said to Liu Bei: "Xuande, after you build the cement plant, store as much cement, steel bars and sand as possible, and don't disclose cement-related matters to anyone for the time being."

Zhuge Liang's eyes flashed when he heard the words, as if he had thought of something!

But Liu Bei asked suspiciously, "Shouldn't we use it immediately?"

Such a good thing, why not immediately use it to pave roads, repair bridges, and build houses?

Lu Yan pointed to the northeast and said: "I want to lay roads in the west of Liaoning, and I want to build three strong cities in the west of Liaoning, so I need enough raw materials!"

"!!!"

After hearing Lu Yan's "ambition", Liu Bei slowly widened his eyes, and Zhuge Liang also opened his mouth slightly.

"Sir...do you want to..." Zhuge Liang asked in a whisper.

"That's right!" Lu Yan grinned at the corner of his mouth, and said proudly: "After Liaoxi is Liaodong, after Liaodong there are Sanhan and Goguryeo! I want to collect all the grasslands, and I want the north to be my territory. I want to eradicate the troubles of the grassland forever!"

Zhuge Liang and Liu Bei were frightened by Lu Yan's "crazy" idea.

But now with cement, building roads and cities in the grasslands is not such an unattainable dream.

The two of them were infected by Lu Yan's pride. At this moment, there seemed to be a panic in their chests, and there was an urge to scream up to the sky to feel comfortable.

Seeing that the two of them were a little uncomfortable, Lu Yan couldn't help smiling and said, "It's easy to say, but it's very difficult to actually do it."

After Zhuge Liang and Liu Bei were poured a basin of cold water by Lu Yan, the burning flames in their chests became slightly smaller.

"But no matter what kind of difficulties and obstacles lie ahead, we are going to do this... So brother Xuande, how much cement, steel bars, sand and stones you have, stock up for me!"

Excited, Liu Bei clasped his fists and performed a military etiquette: "The last general swears to die to complete the task!"

Lu Yan nodded, then turned to Zhuge Liang, and said, "Kong Ming, arrange the manpower for the shipyard as soon as possible, and free yourself from the tedious work. Old Geng is not young, and his health is not very good. I am afraid it will not be possible to be a prisoner." It will take you too long to take over."

The Jiangzuojian was established and developed by Lu Yan on his own, and it is the core and most precious property for Lu Yan.

Liu Bei heard that Lu Yan intended to hand over the supervisor to Zhuge Liang to take care of him.

Immediately understood,

Lu Yan, this is to train Zhuge Liang as his successor!

Chapter 439 Ma Chao's Blood Feud

The envoy sent by Ma Teng has arrived in Xuchang, and the tearful accusation of the envoy above the court made those who heard it sad and those who heard it cry.

After learning about Han Sui's insidious methods, all the princes and ministers strongly condemned Han Sui.

But the courtiers scolded for several days, but they just couldn't see any action on their hands.

But the envoy didn't blame them, he knew it was because the military and political power was actually in the hands of Cao Cao.

The control of Hebei has not yet been fully stabilized, so Cao Cao has stayed in Yecheng for a while, and rarely comes to Xuchang when there is no major event.

For the imperial court to send troops to help, this kind of matter must be decided by Lao Cao himself, so no matter what the envoys are not in a hurry, they have to live in Xuchang temporarily, waiting for the news from Cao Cao from Yecheng.
