And in Lijiazhuang.

Since Empress Changsun and Li Yuan and Li Shimin's concubines, princes and daughters left, Li Xuan has completely lived in the bedroom.

When the weather picks up and the permafrost is unblocked, you must start digging ground and building houses.

Moreover, two layers have to be stamped.

At that time, no matter how many people come, I will be able to stay in the room on the second floor!

Thinking of this, Li Xuan couldn't help but feel full of motivation.

Now, the iron smelting furnace in the small workshop next to it can easily produce 1,000 kilograms of pig iron in a day.

At most, improve it yourself to turn pig iron into steel.

After all, when building a house, the steel bars are poured inside.

As for the bricks!

It seems that when he went to Chang'an City last time, when he was at the gate of the Wang family, it seemed that the Wang family's courtyard wall was built with some exquisite strips of blue bricks.

Then, there should be many brick kilns in the Tang Dynasty, and bricks can be placed aside first.

Then, the most important thing is cement!

It seems very simple to make cement.

Among them, the most important ones are limestone, clay, iron ore, and coal.

All things are easy to find, but the limestone was used to build houses in ancient times.

It seems that the half-hole building of ancient humans had lime added in the middle.

Even if the adobe walls in the houses of the villagers in Lijiazhuang are first applied with fine yellow mud, then a layer of straw mixing mud, and finally a lime surface is applied.

After using it all morning, Li Xuan carefully sorted out all the materials needed to build the house, and he couldn't help but be excited. There was great potential for this.

Immediately, Cheng Chusi called Ying Qi and Wu Fu, the iron-smelting team in the forging workshop.

"Ying Qi, Wu Fu has met Master!"

"You two don't need to be polite!"

Li Xuan said with a smile on his face.

"I wonder if the Master called me to come, but what instructions do you have?"

Now, Ying Qi and Wu Fu are both proud and satisfied.

Although he is still stationed in Lijiazhuang, he supplies two little craftsmen ordered by Li Xuan.

However, because I was learning some knowledge with Li Xuan every day, I had long been highly valued by Gongsun Nian.

As long as Li Xuan no longer needs these two people, once he returns to the prison, he will be the master craftsman in the prison!

"I wonder if you two know how to burn lime?"

Li Xuan asked.

"The Master underestimated people. Anyone who is a craftsman will burn lime!"

Ying Qi and Wu Fu were stunned and said quickly.

“So great!”

Li Xuan was happy, "So you two know where there is the most limestone?"

"Don't worry, the mountain is full of limestone. However, when choosing limestone, you need to pay attention to the quality of cyan limestone, while yellow and white contain impurities such as clay, minerals, etc.."

Ying Qi and Wu Fu said: "However, in the Xishan area, there is a lime kiln with calcined limestone. If Master needs lime, he can buy a large cart for ten cents!"

"I don't burn lime!"

Li Xuan shook his head slowly.

"Why does Master want it?"

Ying Qi and Wu Fu were stunned and full of doubts.

"I'm going to burn cement!"

Li Xuan said slowly.

"cement?"

The two of them looked confused again, "Dare you ask Master, what is cement?"

"cement……"

Li Xuan opened his mouth and was also stunned.

How should he explain this kind of thing that has never happened before?

However, Ying Qi and Wu Fu's expressions changed slightly when they were hesitant. Thinking of the words their boss would be the words that the supervisor Gongsun Nian explained to them a few days ago.

This person who doesn't want to disclose must not inquire about things that he doesn't want to disclose, nor can he reveal them. Otherwise, the least the person will fall to the ground, and the worst will cause the whole family to suffer!

Grilled

Qi Qi shivered and quickly bowed and said, "I'm waiting for too much, please don't blame me!"

Forehead!

Seeing this, Li Xuan was stunned.

He smiled bitterly and said, "This is the first time I've burned this thing, and I don't know how to explain it to you. However, when the fired it will be revealed!"

"I see!"

When they heard that it was not something that needed to be kept confidential, Ying Qi and Wu Fu couldn't help but breathe a sigh of relief.

However, he was soon full of curiosity.

"I don't know how to burn cement?"

“It’s also very simple to burn this product!”

Regarding this, Li Xuan thought about it all morning and probably came up with the simplest set of firing methods.

Therefore, it is very smooth to say.

"Cooking cement means limestone, clay is ground into flour, and then calcined into clay. Finally, grind the clinker and the remaining slag after iron smelting and grind it into powder, and it is cement."

“So simple.”

After hearing this, Ying Qi and Wu Fu's eyes lit up.

“That’s right!”

Li Xuan nodded slightly and continued, "However, I need a lot of cement to build houses and build roads, so I will need to trouble you two in the next period of time."

“Build a house and build a road?”

Hearing this, Ying Qi and Wu Fu were stunned again.

“It is to build roads and build houses!”

Li Xuan nodded affirmatively, "As for how to build it, you will know when the two of you fire the cement out!"

"As for what materials are needed, you can just go to Cheng Chusi, Gao Ming and others to buy them. There are several large boxes of money in the side room in the courtyard of Benfu. You can buy them at will, even if you spend them all, you don't have to worry about it. You can make a lot of money soon!"

"I understand!"

Ying Qi and Wu Fu have heard Li Xuan's arrogant words many times.

However, every time the corners of the mouth twitched straight.

Afterwards, the two of them discussed the necessary materials to Cheng Chusi.

As for going directly to find Prince Li Chengqian?

Although the Cheng family Shaolang looked much more fierce than the kind-hearted prince, the two were still willing to communicate with Cheng Chusi.

Soon, Cheng Chusi found Li Chengqian and discussed it. Several people opened the side room in Li Xuan's courtyard and took out two stagnant coins.

"ah?"

However, what the few people did not expect was that when they turned around, they saw Li Yuan standing quietly behind him with his hands in his arms, full of curiosity.

"Sanlang is going to make trouble again?"

"Returning to Aweng, the Master asked Ying Qi and Wu Fu to burn an object called cement to prepare for road construction and house construction!"

Li Chengqian hurriedly reported.

"Um!"

Li Yuan glanced at the two staples of money in the hands of several people, nodded slightly, and left staggeringly.

Left a group of Cheng Chusi, Li Chengqian and others who looked at each other were stunned for a moment, and hurriedly carried the two jin of money and ran out of the village.

No matter what, the affairs of the Master are the most important.

Now, because Li Xuan would have some new ideas from time to time, Li Chengqian, Cheng Chusi and others have already developed a way to deal with it.
