I pretended to ask about the elevated ditch, but I was actually asking how those things were made.

As long as the manufacturing method is mastered, it can be copied in large quantities.

However, as soon as Li Er finished speaking, Zhao Mu shook his head.

"Do you know what really powerful that thing is?"

Li Er shook his head, but nodded heavily in his heart.

I have already seen the power of that thing, and if I master this method, I can continue to build this city and make it more impregnable.

If there was such a thing back then, the entire Chang'an City would be built ruthlessly.

Back then, those Turks besieged the Tang Dynasty and besieged Chang'an, even if they doubled their troops at that time, he would not negotiate peace with his Turks, and would definitely fight with them to the end.

"You, after all, are just a businessman, and what you value is only profit.

You're talking about cement, right? ”

"Brother Xian is the reinforced concrete."

"It's made of cement and steel, let me tell you, I can make the cement and sell it directly to you.

When the time comes, you will install and purchase it yourself, but I will definitely not be able to sell you this cement manufacturing method.

If it is sold to you this time, it will harm you. ”

"Ah, this?"

"If you sacrifice this thing to the court and give him Li Er, what awaits you at that time is just a dead end."

"Brother Xian, are you joking?

If I buy it, if I dedicate it to His Majesty, how can I die out? ”

"Hehe, you're too young to know what an emperor's heart is.

This cement, mixed with sand and gravel, will surely make the city impregnable.

If Chang'an City is built and continues to be built, it can be built higher and stronger.

In the previous battle, as long as 4 times or 5 times the enemy besieged, it may be possible to capture the city.

But if you use this thing, not to mention 4 times or 5 times the enemy, even if it is 10 times 20 times.

The soldiers defending the city, as long as they have enough food, can also hold the city and be unbreakable.

If this thing was discovered by the court of the Tang Dynasty itself, it would have been made by the court.

But this thing was made by you, a businessman, and you can contribute to it because of your interests.

You can also sell to other surrounding alien races because of profits, let me ask you, does Datang have powerful siege weapons? ”

"Brother Xian, does this catapult count?"

"Of course that's a thing, but can a catapult push all the city flat?

Attacking the city only played a role in promoting, but it could not be used as the main force.

It can be a fierce blow to the current city, if the entire city is made of reinforced concrete.

Datang's catapult is a toy compared to it.

If they are learned by the aliens around them, they can build their own cities bigger and stronger.

If they were at war with the Tang Dynasty, it would be just a matter of fighting on land.

If the Tang Dynasty starts a siege battle, the number of soldiers injured will be even more than the previous ones.

If you were the emperor, would you pass on the method of making this cement to the surrounding aliens? ”

Li Er shook his head.

"Isn't this enough, if the secret of the Tang Dynasty is passed on to the surrounding alien races.

Let its city be built like this, so that the soldiers of the Tang Dynasty suffered heavy damage, you are the emperor, will you be angry? ”

This?

If the court finds out that it is made, you can also suppress this method and use it quietly by yourself, so as not to spread it.

Even if it's a spread, you can find people as soon as possible.

It's a pity that you offered it, do you think the court will kill you?

Brother Xian, the Holy One wouldn't do that today!

"Of course he won't do this, that's because some things don't touch his interests, and they don't touch Datang's interests.

But if things touch his interests, they touch the interests of Datang.

It's not something you can control.

Do you think it's the wine?

I'll sell you the drink, and at most you'll make some money.

This includes the new ploughsticks, the seeders, and now the waterwheel.

Even if you buy it and want to offer it, for you, it is only a hundred benefits and no harm.

But if you offer something like cement, you're going to die.

Listen to my advice, there are some things you can't grasp. ”

I......

Li Er only felt a crow fly in his heart, and what the virtuous brother said was still very reasonable.

That is to say, he knew that this thing was made by Zhuangzi, who was a virtuous brother, but if this thing was known to him, he would definitely receive it from him at all costs.

Let all the people who know this method cut down the grass and eradicate the roots, and then the method will be controlled by the court, and the entire world can be built.

This will allow the entire city to be more defensible and defend against any enemy attack.

This time, I was a little in a hurry.

"Brother Xian, you really woke up the dreamer with a word, my Lao Li almost danced on the tip of the knife, you are right, right."

Li Er nodded secretly, but actually muttered quietly in his heart.

That's it, at this moment, Datang is fighting in the Turks, waiting for the Turkic campaign to end, and he is not in a hurry about this cement.

"Young master, the food is ready at the restaurant!"

"Huh? Is Brother Xian going to eat so soon today? ”

"This morning a ploughing cow broke its leg, and I thought I would send someone to treat it.

But the cow's leg was so badly injured that there was no way to arrange for someone to slaughter it at noon today.

It just so happened that this afternoon I wrapped a little beef stuffed dumplings, beef and green onion flavored, you have a mouthful. ”

Li Eryi understood it instantly when he heard it.

"Yes, Brother Xian, why do you think this cow is so unlucky?

How can you walk and break your leg? ”

"yes, this cow is indeed unlucky."

Understood.

We ate beef quietly. And for that reason.

"I said Lao Li, why do you feel like you don't trust me in this look?

I'm not kidding you, that cow really broke his leg! ”

"I understand everything, I understand, I didn't say anything else, that cow originally broke its leg, I can only say that its fate is not good."

Hearing what he said, Zhao Mu glanced at him disdainfully.

It's come to this, believe it or not.

It doesn't matter how he broke it, anyway, I'll have a good mouth again tonight.

Came to the restaurant to eat a meal of beef dumplings, left Zhaojiazhuang the next day, while holding the drawings of the waterwheel, before leaving, he cut more than a dozen catties of beef, which can be said to be a full load.

On the way to Chang'an, I passed by the elevated ditch they were laying there, thinking that I couldn't get it at the moment, so I simply couldn't see it out of sight and didn't bother, left here, and hurried in the direction of Chang'an City!

When I arrived in Chang'an City, the first thing I did was to call the personnel of the Ministry of Works.

gave the drawings of the waterwheel to the people of the Ministry of Industry, and Li Er told them what the use of this thing was.

When the Ministry of Industry and his entourage heard His Majesty's speech, they all showed shocked expressions.

If this amazing immortal method is popularized in the Tang Dynasty, the grain output of the entire world will definitely increase significantly.

The officials of the Ministry of Industry directly began to pat themselves on the back.

"Congratulations to Your Majesty, congratulations to Your Majesty, congratulations to Your Majesty, congratulations to Your Majesty.

My Datang has such an artifact, and Weichen immediately arranged for people to build it.

After the construction of my Chang'an City is completed, I will arrange this thing to various state capitals and counties outside my Chang'an City.

We must rush before the summer of this year to make it available to the whole world. ”

Hearing what the Minister of Industry said, Li Er threw him a roll of his eyes.

Tian Tianjing knows what to do, what to do at the critical moment, and what to eat is not enough.

But if you have any of these things, you can make one of them.

Now I am stunned to become a migrant worker and carry out transportation in Zhaojiazhuang.

Fortunately, after moving by yourself, you can get a lot of money from the household department to fill your vacancy, otherwise who else?

Do you really think that it is thankless to become a part-time worker?

By the way, what about the household personnel?

Even if it only costs tens of thousands of dollars this time, the money that should be black still needs to be black, so that you can soothe your sad heart!

Just when his personal internal official went to find the Minister of Households.

"Nearby, let's get something out!"

"Yes, Your Majesty."

The eldest grandson Wuji opened his pocket, asked someone to fetch a cloth bag, and poured out the cement he was carrying.

Who is Li Er?

After observing the cement plant that day, he knew that the cement was a bit of a struggle.

When he was simply observing, he asked the eldest grandson Wuji to carry a few handfuls and put them in his clothes.

When I returned to Chang'an City, I arranged it for the Ministry of Industry to make it and see if it could be made.

Seeing the object in the bag, the staff of the Ministry of Engineering looked dazed.

It's like dirt and it's not the color of soil, it's like sand, but it's not so fine.

And the color of this thing, but the first time I saw it, I had to look up at His Majesty with a question mark.

"This thing doesn't have a name, you take it to the Ministry of Industry and send someone to make it yourself.

If you can build success, you will succeed, and if you can't succeed, I don't blame you. ”

"Your Majesty, Weichen takes the order!"

An unnamed thing made me very puzzled, so I had to carry the bag and hang it in my clothes.

A moment in time.

When the household staff rushed to the palace, they saw His Majesty sitting above, and the Ministry of Works personnel on the side.

And they held the drawings in their hands and instantly understood them and saluted.

"Your Majesty, how much money is expected to cost this time?"

You listen, you listen, this is called enlightenment, the leader has not said it, it can directly solve the pain in the leader's heart.

Li Er doubled the number and said it, and the household staff exhaled deeply in their hearts.

It's really strange this time, Your Majesty actually asked for so little money?

After arranging, he stepped aside and glanced at the staff of the Ministry of Engineering standing beside him.

Seeing the ministers on the side, he wanted to strangle them to death, so he had to quickly turn his head around.

Say silently in your heart, you can't see me, you can't see me.

Li Er waved his hand, and the staff of the Ministry of Engineering, holding the drawings and cement, saluted, and left the place in a hurry.

There was a hint in his eyes at the minister, as if to tell him about another victory of his own.

The household official scolded him angrily in his heart.

It's really hateful, turn your head and look at Your Majesty with a smile!

"Is that grain ready for storage?"

"Your Majesty, all the grain has been put into storage, please rest assured.

Old grain from previous years has also been distributed to the state capitals and counties in case of emergency.

Your Majesty, if the food we are preparing now encounters some ordinary minor disasters, it will be able to resist them.

Aren't we taking precautions in the first place, a little too much? ”

As the saying goes, prevention is better than prevention, and everyone can understand it.

But today's precautions, isn't it a bit too precautionary?

Even the household officials, as His Majesty's confidants, still asked what was in their hearts.

"Actually, why don't I want to take precautions a little too much?

But I'm worried that this year's drought will be worse than usual! ”

"Your Majesty, this year's spring in my Tang Dynasty can be described as a smooth wind and rain, this summer drought?"

"I hope it's fake, so you just do what I command.

Remember, extraordinary times do extraordinary things! ”

"It's Your Majesty, Weichen is commanded!"

After the Minister of Household and Ministry of Industry left, Li Er sat down in a chair again and rubbed his head.

Thinking of these bad things, he hoped that this time it was the virtuous brother who said things wrong.

But what did Brother Xian say, which one of them not become a reality?

It's better to take precautions than to do so!

In the following time, Li Er stayed in the palace and continued to work hard.
