"Uh-huh......! Looks like I'm wrong to blame you. ”

Li Er was stunned for a moment when he heard this, and then suddenly, the anger on his cheeks was suddenly swept away, and when he looked at the public toilet again, he didn't think he was an eyesore.

If this building material can really be popularized, then even if there is a war, he Datang can be invincible.

"This is not true, although cement can be used to build city walls, but my real intention is to help the people of Datang solve the problem of water leakage in their houses!"

"Your Majesty, I don't need to verify the hardness of the cement, and we haven't tested the waterproofness yet, come on, bring water to pour it on me!"

Zhao Yin shook his head slowly, his original intention was really not to build a city, he just wanted to build a cement road to make himself more comfortable when he went out, and secondly, it could be regarded as meeting Li Er's request.

The order of the master of the horse was no less than that of His Majesty, so the guards directly took the bucket after receiving the order and began to pour water on the thatched house.

"Okay, you can stop, Your Majesty, how about we go over and see?"

After about a stick of incense, Zhao Yin asked the guards to stop and took the lead in the thatched house.

"I really didn't expect that the waterproof effect is so good, and after pouring so much water, it is so dry inside?"

In the public toilet, the eldest grandson Wuji was completely shocked.

You must know that even in his Guogong Mansion, when it rains heavily, there will be rain leaks, not to mention ordinary people's houses.

"Your Majesty, as far as I know, among the people of the Tang Dynasty, there are still many people who still live in mud houses, which not only have poor thermal performance, but also leak rain. But if you switch to a cement house, not only do you not have to worry about rain leakage, but you can also greatly increase its warmth! ”

"As for the roads in Chang'an, we can also use cement, which is not only waterproof, but also tough!"

Zhao Yin talked confidently, and Li Er's eyes became brighter and brighter.

"Is that true? Can this thing really solve the suffering of the people? ”

The eldest grandson Wuji looked at Zhao Yin in disbelief.

"When did this colt deceive you? If Zhao Guogong doesn't believe it, let's make a bet! ”

Zhao Yin pouted, every time he was like this, his words would always be questioned by others, but when it came to betting, these guys would immediately admit it.

"Forget the bet, I just don't know how much this thing costs? Will the people be able to afford it? ”

The eldest grandson Wuji looked at him, he was not stupid, just forget the bet.

"Yes, although the country is safe now, if the price is too high, those poor people still can't afford it!"

Although Li Er was very satisfied with this kind of cement house, he also thought about the price.

"The cost is bound to be higher than that of a mud house, but at the same time, the life of a cement house is much longer than that of a mud house, even if you live for a lifetime!"

Although the process of making cement is still immature, the cost is relatively high.

However, it will not be long before the craftsmen of the clay kilns will complete a large amount of cement firing, and by that time, the cost of cement will be greatly reduced.

And, such a clay kiln, there are many around the Tang Dynasty, just firing terracotta, there is really no prospect, although the Tang Sancai in later generations is more awesome, but in this period, it is really useless.

It is better to transform the mud kiln into a brick kiln and a porcelain kiln, and fire out some more practical tiles, which can definitely make a lot of money with the use of cement.

"But no matter how strong it is, if the people can't afford it, it's useless!"

Zhao Yin's words, the eldest grandson Wuji has no doubts, but this kind of thing looks simple, I'm afraid the cost should not be low.

"It's just the initial stage, the technology is not mature, and once the technology is mature, the price will naturally fall."

Zhao Yin patiently explained, "Moreover, the imperial court can cooperate with the renovation of the house, as long as you want to build a cement house, the imperial court can give a certain degree of subsidy, as long as you register with the local officials!" ”

"You kid, are you asking me to pay for it?"

When Li Eryi heard this, his voice lowered a little more.

It is a good thing that the people can live in cement houses, but if every household asks the court to pay for it, it will be really a lot of pressure on the treasury!

"It's not that Your Majesty will start promoting cement houses now, but that in a few days, when the son-in-law can produce cement in large quantities, ......!"

Zhao Yin knew what this old picker was thinking, so he came to his side and continued to explain: "At that time, the cost of cement can be greatly reduced, and the imperial court only needs to pay a small part, so that the people will not only receive your affection, but also improve the living environment of the people!" ”

"Okay, that's it!"

Li Er thought about his words for a while, and then quickly agreed.

Now the treasury is abundant, and there are still a lot of dividends to be paid, and Zhao Yin brought back a lot of gold and silver on this expedition.

If a part of it is used to support housing reform, it should not cause any burden on the national treasury, and it can also win a good reputation.

It's a good deal!

"Your Majesty Shengming!"

Zhao Yin hurriedly surrendered his flattery.

That day, Li Er promised him that as long as the people's housing problem was solved, he would allow him to take a concubine.

Now he has said that he has moved this old pick to pay for the goods, and the rest is waiting for the cement to be listed in large quantities.

……

In the technical school, Zhao Yin kept flipping through the roster, and although there were more than several times more craftsmen as supervisors than before, it still couldn't meet his needs.

In the end, he could only set his sights on Zhenguan Technical School, which was established to provide talents for his own projects, and now it can come in handy.

"Are you looking for me?"

Hou Qingli looked at Zhao Yin with burning eyes.

Ever since she knew about the bet, her heart had been pounding, and it wasn't until today that he appeared in front of her, which suddenly overwhelmed her.

"Hmmm! Do you have any outstanding students in your school? The craftsman's piece. ”

Zhao Yin put down the roster and asked lightly.

"That's it?"

Hou Qingli's eyes widened and she looked at Zhao Yin in disbelief.

Her heart was ready, just waiting for him to make a request of herself!

But she never expected that the words he said would be 108,000 miles different from what she thought in her heart, and a fiery heart instantly cooled.

"Or else? Do you really think I'm idle? ”

Zhao Yin glanced at her angrily, I really don't know what kind of crazy thing this woman is smoking, and what kind of temper she plays with her.

"There are no mediocre talents in the school, what kind of people are needed, find out for yourself."

After taking out a roster and throwing it by his side, Hou Qingli turned around and left directly, not caring about the goods.

"Inexplicable!"

Zhao Yin watched her leave with a bewildered expression, and kept slandering in his heart.

Could it be that her aunt is here?

Otherwise, why are you so short-tempered?

I was not in the mood to worry about her, so I directly picked up the roster and walked out, and after selecting hundreds of trainees, I was directly sent to the general prison for training, and once he passed the probationary period, he could directly stay in the general prison and serve.

This can't help but make these hundreds of students gear up one by one, and the opportunity is in front of them, and they will definitely not miss it, this is the opportunity to shine on the lintel.
