However, Chen Wu repeatedly told the soldiers of the border army not to be despised and despised by craftsmen, and once discovered, they would be punished by military law.

Previously, Lu Tian was only to keep the border army from friction with the craftsmen.

If there is really a matter of the border army bullying the craftsmen, it will only be a punishment and it will pass.

Not long ago, one of his centurions had a clashing with a craftsman.

not only led his subordinates to insult the craftsmen, but also led a group of soldiers to gather and beat them.

Afterwards, in order to prevent him from being punished by military law, Lu Tian deliberately rushed to Chen Wujun's tent to intercede.

However, Chen Wu still chose to behead the centurion.

Lu Tian was extremely puzzled by this move.

He believed that only by throwing their heads and spilling their blood could the border be protected.

These craftsmen are not qualified at all, and they are on a par with the centurions under his command.

Chen Wu alone knew that the status of these craftsmen was not much lower than that of the soldiers under his command.

Among these craftsmen, many are treasures of military factories.

This time, I set off with the army to see how effective the weapons researched by the military factory were.

What needs to be improved.

Before leaving, Zhuge Liang specially told him.

In the event of a crisis, one craftsman can be guaranteed to return to the border, and the rest can be discarded.

These are all secrets that Zhuge Liang told him, and no one knows except him.

Therefore, Chen Wu could only kill chickens and monkeys, and let the soldiers under his command be polite to these craftsmen.

Under Lu Tian's supervision, a group of craftsmen rushed to the outside of Yundong City.

Everyone looked at the dilapidated city wall in front of them, and without the slightest hesitation, they picked up their tools and put them into work.

Among the craftsmen, there was a tall man who ran back and forth among them, constantly pointing and pointing.

After a while, he walked to the place where he and the gray pointed out that the other party was not in the right proportion.

After a while, he walked to the place where the wall was built and said that the other party's posture was wrong.

From afar, it looks extremely lively.

On the side, Lu Tian looked at the busy figures of the craftsmen, and his expression was full of disdain.

According to the current progress, if everyone wants to restore Yundong City, it will take at least ten days.

During this period, these soldiers had to stand by to prevent accidents.

If there is a shortage of manpower, they have to turn into farmers and contribute to the construction of the city wall.

Beside him, an adjutant general quietly rushed over and said rather unhappily.

"General, we're going to wait here for a few days!"

"The city defenses of Yundong City have all collapsed, and it will take at least ten days to repair them all!"

"The daylily will be cold by then!"

He said, looking at the craftsman with some displeasure.

The centurion who was slain was one of his men.

Previously, he went deep into the Xiongnu and killed seven Xiongnu miscellaneous pieces, and made a lot of military achievements.

Such a subordinate did not die on the battlefield, but was dealt with by military law for beating the craftsman, which made him extremely unhappy.

Not just for this rule, but also for these craftsmen.

He already looked down on the craftsman in his heart, not to mention that there were frictions and contradictions among the people.

Lu Tian looked at the craftsman not far away, and said with a look of disdain.

"Where it takes more than ten days, it only takes three days to get it!"

"I'm going to see how they can do this in three days!"

After speaking, he crossed his arms and watched a group of craftsmen working not far away.

As time passed, he realized that something was wrong, and the craftsmen quickly reconciled the cement and cleaned up some of the debris of the city walls.

In front of them was an empty space.

The craftsmen went back and forth, digging a groove and then starting to pile up the groove with bricks.

Then fill in the gaps with cement and smooth out the unevenness.

As more and more craftsmen began to build the walls.

What was once empty ground is now a simple wall.

Lu Tian, who was not far away, was already dumbfounded at this time.

Was the wall built so quickly?

Don't you need to cut boulders, don't you need to carry them manually?

According to his previous memory, the construction of such a wall should have started with cutting boulders.

Then it is constantly piled up, and finally the vacant places are filled with sand and gravel.

Now the craftsmen rub the plank back and forth.

Then use bricks and stones to keep flattening, and those with strange shapes are fixed with cement.

If you follow this process, you will be able to finish the wall in front of you tomorrow.

The remaining three walls are three days, how can it be so fast?

Early the next morning, Lu Tian, as a patrolman, got up early.

looked at the city wall not far away, and was stunned.

A third of what was already built overnight?

As the craftsmen got up, the walls were built at an ever-increasing rate.

It is constantly taking shape at a speed that is visible to the naked eye.

Yesterday's lieutenant general also rushed to his side at this time, looked at the city wall not far away, and asked suspiciously.

"General, can such a wall be strong?"

"It looks a little unreliable!"

Lu Tian himself looked at the city wall not far away, and thought the same way.

Can the walls built so quickly be reliable?

You won't fall over with a single touch.

Not far away, Chen Wu finished inspecting the surroundings and rushed straight to the place where everyone was, he walked up to Lu Tian and asked suspiciously.

"How's it going, how are the walls built!"

Lu Tian pointed to the city wall not far away and said, "Half of it has already been built!" ”

"But there is a question about the lowly position, can the walls built so quickly be strong?"

He looked at Chen Wu's eyes full of doubt.

For Lu Tian, it will definitely take some time to build the walls to get the stones to fit together.

Otherwise, how can you ensure the strength of the city walls?

It's not enough to rub back and forth with some planks.

Chen Wu looked at the lieutenant generals beside him and said suddenly.

"You don't believe it either?"

As the lieutenant generals shook their heads again and again, Chen Wu knew what everyone was thinking.

These lieutenants under him are still quite dissatisfied with these craftsmen.

In particular, we still don't know enough about cement.

He decided to explain it to everyone himself, and the joke came out later.

He had a bag of cement brought in and some river water poured into it.

After waiting for the mixing to be completed, the spiritual power is activated to speed up the solidification of the cement.

When everything was done, there was a piece of concrete in front of him.

Chen Wu said while busy working.

"This cement is a treasure that the craftsmen of the military factory have researched overnight!"

"It can be used not only to build houses, but also city walls, and to be used in the construction industry with good plasticity and connectivity!"

"Houses made of cement are dozens of times stronger than ordinary houses!"

Before he finished speaking, all the lieutenants said in great disbelief.

"How can it be dozens of times!"

"Is this cement that magical?"

Everyone looked at the cement in front of them, which was not different from the soil, and their hearts were in disbelief.

It's just a lump of mud made of water and water, what's so special.

Chen Wu looked at everyone's expressions and casually threw a piece of concrete to the other party.

"You pinch it and see what the difference is with mud!"

The latter turns out concrete, gently pinched.

The image he expected to be easily crushed by himself did not appear.

Instead, there was a pain in the palm of his hand.

Look at the group of lieutenants, he secretly worked hard, and even the green tendons gradually exploded.

Click!

There was a crisp sound, and all the cement in his hand turned to powder.

Jumping everywhere.

Beads of sweat the size of beans dripped from his forehead, and his face turned red.

His appearance was obviously a scene of overexerting force and holding his breath for a long time.

Everyone on the side was stunned when they saw this scene, is this cement really so terrifying?

In doubt, everyone picked up a ball of concrete and put it in the palm of their hand, and then squeezed it hard!

The same scenario is repeated over and over again, and it takes extreme force to crush the concrete.

When everyone crushed the concrete in their hands, they all looked at Chen Wu with puzzled eyes.
