Datang: Destroy Tang Taizong Li Xiao at the beginning

After high-temperature processing into lime, add an appropriate proportion of soil materials, mix well, and then perform high-temperature processing again. At this time, the semi-finished cement is fired, which is in the shape of lumps, and will become lumps after air-drying.

At this time, stir again for processing, and eventually it will become a powder.

In this way, it has become a common cement in later generations.

Because steel was made before, high-temperature equipment is already in place, so it can be manufactured.

Buildings made of cement are not only sticky, but also very strong.

If iron bars and goose warm stones are added, the city wall built can be called the first fortification in this era, and it is not an exaggeration.

Even if it is artillery, it is estimated that it will cost a huge amount of ammunition to break through the city.

"Your Highness, can this stone be turned into a treasure?" Zhao Yuntian asked suspiciously.

"Just wait and see."

Li Xiao knew that he couldn't explain it, so he didn't bother to say more.

The next day.

According to Li Xiao's instructions, the blacksmiths rushed to work overnight, and finally produced about a thousand catties of cement in one day.

This is cement with no quality requirements, so a day is enough.

But no matter how poor the quality is, it is enough to disdain the entire Tang Dynasty.

After all, in this era, only stones and clay were used to build city walls.

"In one night, such a big pile of ash was produced?"

Zhao Yuntian grabbed a handful of cement with a look of surprise.

"Your Highness, what are you going to do next?" Li Junxian asked.

"Call those mountain thieves here!" Li Xiao said thoughtfully, "The next step is to start infrastructure construction. The number of people our villa can accommodate is still limited."

"Infrastructure?"

Several people looked confused, they didn't know what the two words meant, and they didn't dare to ask.

Here in Your Highness, anything, anything is miraculous.

It's useless to ask, and they don't understand what His Highness said.

Not long after, Gou Fugui and a group of bandits arrived one after another.

Not only that, Li Xiao also summoned the coolies already in the villa, and there were hundreds of them in total.

"Did you have a good stay last night?"

Li Xiao looked at Gou Fugui and smiled slightly.

In fact, Li Xiao sees that this rough guy is affectionate and righteous.

Otherwise, he would not have left this group of people behind.

"Thank you, Your Highness, for your concern!"

"His Royal Highness is so comfortable here, more than a hundred times better than our cottage!"

Having said that, Gou Fu turned his head to look at the brothers beside him, and asked, "Brothers, do you think so?"

These thieves are still a bit submissive at the moment, unlike Gou Fugui who is naturally escaped.

After all, many of their brothers died at the hands of Li Xiao.

Although they were the ones who made the first move and reaped the consequences for themselves, but this will soon work for Li Xiao, and it is still difficult to change their mentality.

Seeing this scene, Li Xiao couldn't help sighing in his heart, and was even more impressed with Gou Fugui.

If it wasn't for saving the lives of these people, why would Gou Fugui kneel and lick in front of him like a dog?

"Your Highness, what do you want us to do? Just ask."

Seeing that the brothers were silent, Gou Fugui smiled awkwardly.

"build house."

"Building a house? A trivial matter!"

Gou Fugui immediately shouted: "Brothers, move!"

"Your Highness let us have enough food and clothing, we can't repay our kindness with revenge!"

Although there was a gap in the hearts of this group of people, they still did not dare to disobey Li Xiao's order, and everyone took action.

But immediately, after Li Xiao explained the details, everyone was stunned.

"Build a house with this sand and stones? Will that work?"

Gou Fugui and the others looked at the pile of sand in front of them and looked at each other in blank dismay.

"Just do it, don't talk nonsense!" Li Xiao said lightly.

The sand was fished out of the river overnight by him.

Due to limited technology, it can only be fished by hand, and the amount of sand is very small, only enough to barely build a small house.

Next, under Li Xiao's watchful eye, the group of coolies followed Li Xiao's instructions, mixed sand with cement, and then used stones to build a house.

With a hundred people, it only took a few hours to complete the world's first cement-built house.

"Your Highness, if the wind and rain come, the house may collapse!" Gou Fugui said anxiously.

He thought about it for a long time, and he still felt that it was better to explain in advance.

Don't wait for it to collapse, Li Xiao blames it on him.

"Don't worry, go back and rest!"

Li Xiao looked at the newly built small house of [-] square meters and nodded slightly.

Although everyone was a little unfamiliar, they still came according to his request.

noon the next day.

After a day of exposure to the sun, the cement-built house is completely dry.

"Who said it would collapse?"

Li Xiao looked at Gou Fugui and ordered: "The people who call you, no matter what tools they use, as long as they bring down the house, I will give you a lot of rewards!"

"Your Highness, are you serious?"

Gou Fugui looked ecstatic.

He built this house, he still doesn't know.

It's just some sand and dust mixed with stones to build a house.

Not to mention using tools, he felt that he could push it by himself.

"Go ahead, within one stick of incense, if the house collapses, you won't have to work for ten days, and you will be free from work every day." Li Xiao said with a smile.

"Brothers, let's start!"

Gou Fugui was afraid that Li Xiao would go back on his word, so he led people up without saying a word.

At first, they crashed like mad, and the house didn't budge.

Gou Fugui was shocked.

So the hammer was used.

As soon as the hammer hit, the tiger's mouth was bleeding, leaving only a trace of the house, and it didn't shake at all.

But there are only a few hammers, no matter how they beat.

Although the skin of this cement-built house was battered, it was dilapidated.But there was still no sign of collapsing.

"how so?!"

Gou Fugui and the others were dumbfounded when they saw the standing little house.

Chapter 172: Cannon?What is it?

You know, the house was built yesterday.

It was so strong after only one day.

Even with a hammer in their hands, they couldn't do much damage to the house.

Only a little bit of skin debris can damage the house.

Seeing this scene, it wasn't just Gou Fugui and the others.

Everyone present was shocked.

"The problem is with that lump of gray powder!"

Lu Li stared at it for a long time, when suddenly a bright light flashed in front of his eyes.

They have seen stones, sand, etc., and there will be no problem.

The only thing that was strange was the lump of gray powder specially made by Li Xiao at the blacksmith's shop.

"This level of solidity, if it is cast into a wall, is almost as solid as gold, enough to ignore any catapult."

Li Junxian's eyes flashed with brilliance.

Hearing this, Zhao Yuntian was also shocked,

He knew very well that if there was such an impregnable city, Datang would not be afraid of the Turkic and Japanese enemies at the same time.

Even though your two countries have thousands of troops and horses, you can't even take down the land of Datang, how can you go south?

This can play an unimaginable role in international strategy and tactics.

"Your Highness!" Zhao Yuntian suppressed his excitement and asked in a trembling voice: "Is it true that this dust can be produced with only stones?"

It doesn't matter whether something is good or not.

The important thing is whether it can be mass-produced.

"There is no doubt, this cement really only needs stones to be produced." Li Xiao smiled slightly.

"Great!" Zhao Yuntian was overjoyed, "It turns out that this magical powder is called cement."

"Your Highness." Li Junxian sighed even more, "You are really a god, you just took out this kind of thing that changed the whole era, one after another."

"A god? Hehe..." Li Xiao smiled, "Maybe!"

After a pause, he continued: "Don't look at me like that, I'm not a god, what I mean is, these things may have been taught to me by the gods."

"His Royal Highness has really seen a fairy?"

Everyone was startled.

Li Xiao looked at the sky and murmured, "It's just a dream."

"In my dream, I have seen countless gods. There, people use tools to go to the sky and enter the sea. They are omnipotent and can even explore the stars in the sky."

Hearing Li Xiao's words, everyone present was shocked.

"Fairyland! It must be a fairyland!"

Zhao Yuntian said excitedly: "It turns out that His Highness was chosen by a fairy."

Wonderland, what a distant vocabulary.

But if their highness hadn't dreamed of a fairyland, how would he know such a magical thing?

"Your Highness, can you talk about the fairyland again?"

There was strong curiosity in Lu Li's eyes.

In fact, not only him, everyone is very curious.

What does fairyland look like?

"Actually, it's not as good as you imagined. There, there are also forces from all sides, and there is an undercurrent of competition."

Li Xiao paused, then continued: "Wars have also broken out. You may not be able to imagine that an iron bump the size of a war horse can explode with energy that can destroy heaven and earth. It has a radius of hundreds of kilometers, and all living beings are destroyed." die, and nothing will grow for hundreds of years."

"There are also weapons that automatically pursue the enemy across hundreds of kilometers."
