Yan Liben was excited and moved when he saw Li Kuan's insistence on using a large amount of glass to build the new palace.

Obviously, after the completion of the new palace, it will be different from any other building, and it is destined to go down in history.

And he is the master craftsman of Shingu!

"Lord Wang, the subordinates have already understood the problem of lighting, but you just said that there are no huge wooden pillars in the palace, if this is the case, there is no way for the palace to be built tall and spacious."

Yan Liben recognized Li Kuan from the bottom of his heart, and even changed his title to "subordinate" unconsciously.

"Let's go, it seems that if this king doesn't take you to see it with your own eyes, you won't be at ease."

The construction of the new palace, Li Kuan is still waiting to be thrown to Yan Liben to implement it, so the use of cement, he must be let understand it clearly, otherwise there will be some problems when the plan is designed and the building materials prepared.

"Huh? Is there anything special that the prince doesn't know about his subordinates? ”

Yan Liben couldn't help but be very curious when he saw that Li Kuan didn't answer his question, but took him out with him.

"This king will show you a new building material!" 、

……

Chen Dali didn't feel strange when he saw Li Kuan go and return.

In recent days, Li Kuan has come over from time to time, and sometimes he suddenly thinks of something, even if it is already dark, he will come to the workshop and call himself to discuss it together.

"Lord Wang! But what is the new arrangement? ”

"It's okay, Dali, you are busy with your own going, find one of your apprentices to come over and demonstrate the role of cement to Master Yan."

Li Kuan said so, but Chen Dali naturally wouldn't really go by himself.

"Lord Wang, this is the cement you are talking about?"

Yan Liben bent down and grabbed a handful of cement in his hand.

"That's right, it's cement!"

I haven't seen any miracle effect of cement, and Yan Liben is not easy to express his opinions, but he has a faint expectation in his heart.

Why do you have a feeling that building a new palace will become the pinnacle of your life?

"Gravel, sand, cement and water, mix together, leave it for half an hour, and then we'll come back and see how it works."

The mixing of the concrete was not too difficult, but it was just a cup of tea, and a "stone slab" with a finger thick appeared in front of Yan Liben.

"Lord Wang, looking at the cement is very simple to use, but I don't know how the effect compares with glutinous rice lime slurry."

Yan Li was originally a master craftsman, and he didn't need anyone to explain to him, he already knew what cement was used for.

"This king will take you to visit the production process of cement first, whether it is better than glutinous rice lime mortar, you will judge for yourself later."

Li Kuan didn't bother to compare cement with glutinous rice lime slurry.

Although in terms of viscosity, glutinous rice lime slurry is also good, but in terms of strength, it is not the same grade as cement at all.

The most important thing is that it needs to use glutinous rice, which is food.

But as long as there is any other way, Li Kuan will not use this trick.

"Can limestone and clay be calcined at high temperatures to make cement? Is it that simple? ”

Li Kuan is not ready to keep the cement production process secret, the threshold is too low, but whenever a craftsman goes out to talk, people can quickly imitate similar products.

It doesn't even have to be like this, as long as people see the furnace and see the endless flow of limestone and clay transported into it, and the cement that comes out, they can roughly guess the process of making cement.

As a basic building material, Li Kuan did not think about using cement to make a lot of money.

On the contrary, if there are people in various places to build cement workshops, it will be very beneficial to promote the construction of roads and houses in Datang.

"Master Yan, don't you think it's a surprise?"

In fact, Li Kuan wants to say that the firing of glass is not much more difficult than this, as long as the ratio of various materials is figured out.

"Lord Wang, my subordinates suddenly have confidence in the speed of construction of the new palace. If there are enough manpower, and you don't even have to wait until winter, the first phase of the project can be completed. ”

Although he hadn't seen the result of the "stone slab" he had just poured, from the expression on Li Kuan's face, Yan Li could already infer the result.

"Haha~ It's good to have confidence, the cement is there, the glass is there, the bricks and tiles are also being prepared, and the wood that the new palace needs to use is very limited."

Yan Liben thought for a while, "That's really the case, Xingong doesn't use wood much, and the problem of fire can be solved in one fell swoop." ”

"Let's go and see how that thing is going."

Li Kuan is ready to communicate with Yan Liben today and free himself from the tedious work of the construction of the new palace; Anyway, the most critical cement has been made very smoothly.

"Lord Wang, there should be no problem with the hardness of this concrete."

Yan Liben first stepped on it with his foot, then picked up the hammer on the side and lightly struck it a few times, and found that even if this thing was not as hard as granite, it was not much worse.

Previously, according to his vision, many parts of the new palace were to be laid with a large number of hard granite strips, which was a big project.

"Jun buy, you put wood on both ends of this concrete." After Li Kuan finished giving the order, he turned his head to Yan Liben and said, "Master Yan, you personally confirm it, and see how strong this concrete stone slab is?" ”

"Okay, then I'll see the new miracle invented by the prince!"

Yan Liben was not polite after speaking, picked up the hammer and smashed it on the stone slab.

Although Yan Liben is not a military general, he is not the kind of scholar who has no power to restrain chickens.

When the hammer was smashed down, Yan Liben had actually made mental preparations, but when he saw that the hammer was struck, only a small pit was left on the stone slab, and he was still surprised.

"Bang!"

Once again, some debris flew on the slate.

"Bang!"

Yan Liben pushed harder and harder, and the numbness of his arm from the shock of the hammer did not stop.

And the more he beats, the more excited Yan Liben is in his heart.

This shows that the strength of the slate is very high.

"Bang!"

Eventually, the slate finally fell apart!

"Lord Wang, this cement is a good thing."

Yan Liben excitedly circled around the broken slate twice, and then lowered his head to check what was going on where the slate was broken.

Li Kuan's face showed an unfathomable expression: "This is not good enough!" ”

"Huh?"

Yan Liben was a little confused, he already felt that the cement was far beyond his imagination, why did His Royal Highness the King of Chu still say that this was not good enough?

Could it be that His Royal Highness the King of Chu has always been so strict with himself?

It must be.

Otherwise, it would not have been possible to achieve such an achievement at such a young age.

Ashamed!

I used to be too proud, but today I know that there is a sky outside the sky, and there are people outside the world.

It seems that I still have to learn more from the prince.
