Watch the black cannonball that pierces the sky fly farther and farther away.

Lu Heng coughed a little embarrassed and said, "Ahem, what ......, father, this should be the angle of the muzzle." ”

"The people below are also operating for the first time, so some of them are inexperienced."

"I'll just let them fix it."

After Lu Heng finished explaining, he hurriedly asked his entourage to lower the muzzle of the cannon.

aimed at the group of goats that were used as targets by Lu Heng.

Behind the goat, Lu Heng also ordered someone to build a small mound.

So you don't have to worry about what buildings will be damaged if the shells fly out.

After a few series of adjustments.

Lu Heng went over to take a look again and confirmed that this time the muzzle of the cannon was indeed aimed at the goats that were tied to the wooden stakes.

Then he ordered his retinue to clean the chamber of the cannon with a wooden stick wrapped in sackcloth.

Then let them start a second reload.

You must know that in this demonstration, Lu Hengke only prepared a total of three shells.

If they all fly, it will really be a shame in front of Li Er.

Wait until everything is ready again.

Lu Heng motioned to Li Er to give the order to fire again.

"Ignition!"

With Li Er's order, the retinue with the torch also lit the fuse again.

And this time.

With "Bang! After a loud bang.

Everyone in the ordnance prison except Lu Heng.

Almost all of them froze in place.

Because they were a hundred paces away.

A bright red, blood-colored path slashed through the flock like a sharp knife.

The goats in the path didn't even have time to react, and they were all torn to shreds by the huge impact.

Look at the stumps, severed arms and blood flying in the air.

The Tang people, including Li Er, saw the power of the King of War for the first time.

Before Li Er could recover from the shock.

Lu Heng was already explaining to him the use of the cannon in front of him.

"Father, although the power of this cannon is strong."

"But because my body is bulky."

"So it's not suitable for long marches."

"At present, it seems that its greatest use for our Datang is to stand on the city wall for defense."

"That's why I named it the City Defense Cannon."

Speaking of this, Lu Heng paused and said:

"Of course, when the enemy doesn't know we have artillery."

"If you really dare to line up and try to compete with us."

"Then push this cannon out at this time, it only takes one round of artillery bombardment to make the opposite side collapse!"

Listen to Lu Heng's narration in his own ear.

Li Er couldn't help but fantasize in his mind.

If you really have a lot of this kind of artillery in your hands.

If the enemy dares to march ahead of his own camp as he did in the past.

It was just a cannon shot, when countless shells slashed across the enemy's array.

I'm afraid that no matter who the enemy on the opposite side is, it will be swept away by the Tang army in an instant!

If only one day such a vision could be realized.

The Tang Dynasty under his rule, who in all the countries of the world still dares not to surrender?

At this time, Li Er, who was surging to the extreme, grabbed Lu Heng's hand almost uncontrollably.

In a tone that Lu Heng sounded a little numb, he said:

"Sunrise, you really deserve to be my good son-in-law!"

"I have you, just like the world!"

Lu Hengqiang endured goosebumps and withdrew his hand from Li Second.

He didn't want to cooperate with Li Er at this time to play some trick of hating the monarch and the ministers to see each other.

At this time, since Li Er had already eaten the bait.

Then his good son-in-law naturally wants to shine the hook.

"What, Father, though the power of this cannon is immense."

"But as you can see, the amount of iron needed to make this cannon is too great."

"Although after later improvements, it may be able to reduce some consumption."

"However, there are also some artillery ideas in Erchen's mind that are more suitable for following the army in and out."

"So if Father really wants to cast artillery on a large scale."

"I'm afraid we still have to increase steel production first!"

When Lu Heng said this, he pointed to the big chimney of the mini blast furnace not far away and continued to say to Li Er:

"Father, you see, that furnace is the new furnace designed by the sons and daughters in order to make iron faster."

"I named it the blast furnace."

"Now if my father can find a way to increase the amount of iron ore mined."

"I believe that it will not be long before the minister there."

"Father's army will be equipped with these powerful artillery!"

After listening to Lu Heng's words, at this time, Li Er, who had already occupied the brain capacity of artillery, the god of war, still hesitated to kill.

Directly waved his hand and said:

"Sunrise, you don't have to worry about iron ore!"

"After I return to the palace today, I will immediately convene the ministers to discuss this matter."

"Surely today, we will find a way to mine the iron ore you need."

Hearing Li Er's assurance, Lu Heng's eyes suddenly lit up.

This is what you Li Er said yourself!

I, Lu Heng, didn't force you.

You can't regret it because I built too many blast furnaces in my new ironworks!

However, since Li Er is so generous at the moment, Lu Heng naturally has no reason not to strike while the iron is hot.

casually said that other minerals should be mined together.

After all, when the time comes, it will really start large-scale steelmaking.

The alloy process should be considered in advance.

But Li Er naturally agreed to Lu Heng's request at this time, and he didn't hesitate at all.

I didn't even want to leave after I made the promise.

He also asked his entourage to shoot the last shell that he had saved for demonstration.

After letting the corpses of several innocent goats be broken on the spot.

Only then did he leave the ordnance prison with some reluctance.

And wait until Li Er leaves the armory prison and returns to the palace.

He De, who had been prepared for a long time, also seized the opportunity to inform Lu Heng of a message.

That is, the results of the investigation about that Qiguang Ancestor have come out.

It turns out that this old boy has been in charge of the ordnance prison for some years.

So he secretly stole a lot of iron from the ordnance prison warehouse and sold it.

And this time, the reason why he was so concerned about Lu Heng came to the steam engine tested by the ordnance supervision.

I just want to take advantage of this opportunity to make another fortune.

After all, the steam engine is still in the experimental stage.

Another lump of iron about the size of a house.

The amount of iron to be used is certainly not a small amount.

When the time comes, when he makes accounts, he will report more casually, and the extra iron can be taken out and bought at a good price.

Because of today's Datang's iron production.

Many farmers can't even wrap their farming tools around an iron edge.

In some of the more remote areas, there are even iron coins.

The price at which iron can be sold outside, it is naturally conceivable!

After Lu Heng told the reason for this to the group of rookie students under his hands.

They were all ashamed and couldn't lift their heads.

It's a shame that they are proud of learning from Lu Heng on weekdays.

As a result, he was almost sold by others, and he was still counting money for others.

It's a shame!

However, at this time, Lu Heng did not blame them again.

After all, although many of them are beggars who have been on the streets since childhood.

can be regarded as having seen some people's warmth and coldness.

But the ones they have seen are too far from these old oilmen in the officialdom.

This experience of almost being used as a cover was at least an extra lesson for them!

This will still be of great benefit to them in the future.
