"His Majesty!"

"The minister has thought of a way to further strengthen the border!"

"Just use concrete!"

Concrete!

Since the border is not impenetrable, it is necessary to further strengthen the border!

And this concrete is the good method Ning Chen thought of just now...!

"Concrete is made by mixing lime and sand with water!"

"Once solidified, it will be extremely hard!"

"It is most suitable for building small checkpoints in border areas...!"

Lord Ning Guo blushed, as if he had won the first prize.

In this era, a batch of concrete buildings were produced.

That is simply more outrageous than going out to win a big prize...!

Ning Chen was convinced.

Once you find out a reasonable proportioning method to get the concrete.

The borders of the Tang Empire can be even closer!

"At the same time, with this thing."

"Tuyuhun and Tubo will no longer be able to send Qingqi to drive straight in and plunder my Great Tang...!"

Ning Chen was eloquent.

It seems to want to say all the benefits of concrete.

But His Majesty the Emperor in front of him had a face as black as the bottom of a pot.

Picking up a writing brush, he slammed Ning Chen hard, cursing:

"You bastard is a mouthful!"

"Spit spit on my face, Ma De...!"

Chapter 358 Ningchen: It's over, the cannon was shot crookedly, and the house collapsed...! .

In the afternoon, the weather was clear and sunny.

Chang'an City, in Ning Guogong's mansion.

Her Royal Highness the Princess sat dignifiedly on a soft chair, looking at her husband with a slight frown.

in front of her.

Lord Ning Guo of the Tang Empire.

Holding two scrapers, squatting on the ground, stirring again and again...

Concrete...? !

"Husband..."

"You, have you been stimulated by something again?"

Li Mingxue looked at her husband suspiciously, and suddenly felt something bad in her heart.

Could it be that my husband was so stimulated that he became stupid...? !

The dignified prince is actually playing with mud? !

"Husband, don't scare me..."

There was already a little crying in Her Royal Highness's voice.

Because playing "mud" Ning Chen at this moment, he looks very similar to a fool...

Ning Chen: "..."

The Duke was a little speechless, looked up at his wife, sighed, and replied:

"Your husband, I'm not stupid, or if you curse me again, my husband will punish you tonight!"

Upon hearing this.

Her Royal Highness's face flushed red after a while!

She took a sip delicately, and Ning Chen glanced at her, but the smile in her eyes was hard to conceal...

"You're not playing with mud, you're playing with concrete...!"

"Lime, sand, gravel, and water!"

"If you have this thing, whether it is building a city or a small level in the future, it will be much easier!"

"The key is that this thing is hard and cheap, it's really cheap!"

Ning Chen smiled all over his face.

The movement of stirring in the hands is constant, and from time to time, I use a long spoon to pour a little water on it...

The so-called concrete is a kind of adhesive.

in this era.

If you want to build a city wall, or a city.The adhesive used between bricks and stones is a soup made of glutinous rice and other things!

The hardness of this thing is naturally very different from that of concrete!

and so.

Today's Grand Duke is so uncharacteristically and enthusiastically playing with mud...!

"Last year, the reason why my husband was able to bombard the walls of the capital of Silla Kingdom with one shot."

"It's because the Silla King's Capital has been in disrepair for a long time, and the time tightness of the city wall bricks has been greatly weakened!"

"If at that time, concrete was used to build the city wall!"

"Even if you shoot several shots for your husband, it will probably be difficult to break through the city!"

Ning Chen spoke softly, and at this point, let out a breath of foul air.

Her Royal Highness the princess at the side was stunned.

A pair of extremely beautiful eyes, looking at her husband, the eyes are full of admiration and love...

It seems that my husband seems to be omnipotent...!

at last.

After a while, Ning Chen finally finished mixing the concrete thoroughly!

"The ratio of various raw materials has been found, next, it depends on practice!"

talking room.

Ning Chen stood up from the ground and waved, and the guards who had been in the distance ran over immediately!

"As long as you prepare the bluestone slabs and kiln bricks, are you ready?!"

The guards nodded quickly.

Immediately, a large group of people ran over carrying the bluestone slabs and kiln bricks that Ning Chen asked them to prepare.

Subsequently.

Lord Ning Guogong of the current court held the scraper in his hand and began to...

Build walls...!

Everyone present who saw this scene was stunned!

After all, you are the first-rank prime minister of the current dynasty, and the important minister of the country!

Not only playing with mud, but even building walls...? !

"What are you looking at?!"

"Hurry up and get the cannon over here!"

Ning Chen snorted coldly, and glared at his subordinates with some displeasure.

Then he turned around again and began to concentrate on building the wall...

Since the strength of the concrete is to be tested.

Then.

The best way is to build it into a wall and blast it with cannons!

Judge the strength of this concrete building by this!

It didn't take long.

Ning Chen built a wall with the height of one person, with bluestone slabs in the middle and kiln bricks in the front and back!

And at the same time.

The guards of the Duke's Mansion have also brought a rifled gun with the smallest caliber!

After several more hours, the setting sun in the sky was slanting to the west, and it was about to set.

On the open space of Nuo Da's Duke's Mansion.

There is only a dry concrete brick wall left, and the artillery hundreds of steps away...!

"The so-called practice is the only criterion for testing truth!"

"Today, our country will use this cannon to test whether this concrete building is solid...?!"

Ning Chen smiled and pinched his wife's flamboyant face.

Then, amidst Her Royal Highness's coquettish humming, she carried a torch and strode towards the open school grounds!

Looking at the tall wall in the distance.

Ning Chen let out a long breath of turbid air, and his spirit became tense!

As long as today's bombardment can't collapse the concrete brick wall.

This represents the concrete building.

It can be used in the construction of forts and giant cities on the western border!

Its significance is self-evident...

The torch ignited the fuse, and there was a crackling sound.

next second.

A group of flames burst out, and the deafening cannons suddenly sounded!

Between moments.

The cannonball had already drawn an arc under the setting sun, and finally smashed hard on...

"boom!"

There was another loud bang!

Ning Chen looked up, and then his whole body froze in place...!

Grandpa Guo is almost stupid, looking at the situation in the distance, he can't wait to slap himself in the mouth!

That shot just now went wrong...? !

Not only did not test the results of concrete strength.

even.

He also discounted the beams and pillars of a side hall behind the school grounds in his own state's mansion!
