At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 237

After Chen Ying left, Concubine Wang came slowly, carrying the brewed tea.

"Your Highness, are you going on a long journey?"

Zhu Qiyu nodded and said, "Maybe I'll be out for a while."

Concubine Wang asked again: "Where are you going?"

Zhu Qiyu thought for a while, and said, "It's a matter of state affairs, so it's inconvenient to tell us right now."

Concubine Wang seemed to feel something was wrong, her voice was trembling: "Is...going to fight?"

Zhu Qiyu smiled and said: "Don't ask me any more. During the time I'm away, someone needs to make decisions about the big and small affairs in the palace. What's more, you need to take care of Concubine Hang more. Seeing that the child Ji is weak, they The mother and son will be handed over to you."

Concubine Wang nodded, and said softly: "I remember."

Early the next morning, Zhu Qiyu finished his morning court as usual, but instead of going to Wenhua Hall, he went directly to the artillery test base in Xishan.

There is no problem with the strategic layout, and there is no problem with the marching route. As for supplies, Champa rice is grown three times a year, and the logistics are completely guaranteed.

The only thing to be confirmed is how powerful the new artillery is.

Thinking of going out to lead the army to fight soon, I feel very excited.

Now is the season when spring and summer alternate. On the way to Xishan, there is a scene of singing birds and fragrant flowers.

I vaguely remember that when I was a child, I went out for an outing, and the surrounding area was very desolate.

But now the changes are very big, the quarries and cement workshops are in full swing, and there are explosions in the distance from time to time, some are blasting rocks, and some are experimental artillery.

Chen Ying had been waiting here a long time ago, and when he saw Zhu Qiyu coming, he hurriedly saluted.

"I have seen Your Highness!"

Zhu Qiyu replied: "You are welcome, how are you preparing?"

Back then, Emperor Xuanzong liked firearms very much. When Zhu Qizhen and Zhu Qiyu were very young, he took them to the barracks to watch cannons.

If the mood comes, they will be stuffed into the barrel of the gun to play.

Zhu Qizhen was very excited about this, on the contrary, Zhu Qiyu would scream in fright.

Today, Zhu Qizhen has become the emperor, personally leading the army to fight in the north and south, opening up the territory for the Ming Dynasty, and making great military exploits, but he can only stay in the Forbidden City and become a full-time housekeeper.

Last night, he carefully studied the drawings of the new artillery, but he had many doubts.

For this reason, I made a special trip here this morning.

Chen Ying was still waiting to go to the live demonstration, but in the end, he took out a blueprint.

There are many numbers marked on the drawing, including the size and thickness, as well as the general graphics, and even the inside of the gun bore is compared in detail, obviously a lot of work has been done.

"This is the design drawing of the lightweight Flying Tiger Cannon provided by Wang Gong Factory. The size marked on the barrel is really too thin. In this way, although the weight of the cannon itself can be reduced, it is so thin, isn't it afraid of explosion?"

In this era, the thickness of the gun tube wall gradually increased from the muzzle to the tail, in line with the principle that the gunpowder burns from high to low pressure.

Another reason is the current quality of cast iron.

Before the appearance of fine steel, the hardness, brittleness, compression and shear resistance of cast iron were relatively backward. The only way to prevent the chamber from blowing up was to increase the thickness of the pipe wall.

When Zhu Qiyu saw the blueprint of the Flying Tiger Cannon, his first reaction was that the barrel was too thin.

According to common sense, such a barrel is easy to explode.

You can't take the Shenjiying across the ocean to Annan, and blow up your own people before killing the enemy.

Chen Ying scratched his head, not knowing how to explain it.

"Your Highness, why don't you go to the field and try shooting?"

He is a rough man, and he is not very clear about the principles of the new artillery, but he understands a truth, facts speak louder than words.

If you say no, right? Let’s fire it up and see!
Zhu Qiyu nodded, and came to the Houshan shooting range with Chen Ying.

A light Flying Tiger Cannon has already been erected here.

Chen Ying came forward and carefully wiped the cannon body.

Baby, baby, it's finally coming in handy!

Zhu Qiyu's eyes fell on the cannon, and then looked at the blueprint in his hand, it was basically the same.

It's just that the fine iron used for this cannon body is actually more delicate than ordinary cannons.

He circled around the cannon and asked in surprise, "There are no air holes on the cannon?"

Chen Ying shook his head and said, "Return to Your Highness, this is fine iron cast by a forge, without pores."

Zhu Qiyu was amazed. You must know that iron needs to be tempered. Because there is air in it, there are air bubbles inside the iron. The general method is to continuously temper it. Beating with wrought iron is like kneading one side of dough, kneading the air out of the dough.

That's how the term "hundred-forged steel" comes into being. This "thousands of tempering" is actually the way to describe this kind of forging.

If it is a sword, there is no problem with this method.

But casting cannons is different. A cannon weighs over a thousand catties. Is it true that such a large amount of work can't be achieved through hard work?

Therefore, the vast majority of cannons are cast with ordinary steel materials, because there is air in the steel, and after a long time, the air bubbles will form a hollow, and the gun body is also full of pits, so the strength of the gun barrel can be reduced. One can imagine.

But it doesn't matter, the strength is not enough, you can use the thickness to make it together. In order to prevent the fragile barrel from being unable to withstand the impact of the gunpowder explosion in the barrel, so as not to explode the barrel, the craftsmen invented a very clever method, which is to continuously increase The thickness of the gun barrel, an iron bump piled on it, is really not enough, and an iron hoop is put on the outside, regardless of the gunpowder, you can try it by blowing up the chamber.

In Zhu Qiyu's impression, the cannon should be pitted, and when knocked, there will be a hollow muffled sound inside. Such a cannon with a smooth surface is very rare.

So, looking at the thin barrel, his eyes were filled with suspicion.

This thing... is really not afraid of exploding?
"I wonder what the range of this Flying Tiger Cannon is?"

Chen Ying replied: "Your Highness, the one you see is a light cannon with a range of about 180 feet, and there are heavy artillery over there with a range of about [-] feet."

Zhu Qiyu couldn't help but gasp, can this thing have a range of 180 feet?

He had read the previous records. During the Northern Expedition of Emperor Taizong, the range of ordinary artillery was about 150 feet, and the range of some respected artillery was at most [-] feet. The light artillery in front of him didn't look like it...

"That's a test shot!"

Although I am full of doubts, I will know after firing a cannon.

Chen Ying nodded and said, "Your Highness, please specify a target!"

"Specify... what?"

"It is to test the target and test the accuracy of the artillery."

"Accuracy... what is it?"

In fact, smoothbore artillery also has air holes in the smoothbore, so it is impossible to count on it to have an accurate range. Whether it can hit the target depends entirely on luck.

Chen Ying had no choice but to point to the front and said, "Your Highness, please look at the opposite mountain."

Zhu Qiyu covered the awning with his hands, tried his best to look forward, and asked, "I only see a pine forest."

"Your Highness, please look. There is an open space in the pine forest. The last general sent someone to build a pergola there. It has been dyed red for eye-catching."

Zhu Qiyu nodded and said, "I see!"

Chen Yingdao: "The target of this shot is that pergola!"

Zhu Qiyu was a little speechless. The mountain on the opposite side was roughly two hundred feet away. How could he still hit the target at such a long distance?
I'm afraid it's not a dream...

Of course he didn't believe it, but he couldn't make it too obvious in front of the soldiers of Shenji Camp.

"That being the case, let's begin!"

"Order!"

Chen Ying nodded, and then said: "Prepare for test shooting, target, target number one!"

"Got it, target, target number one!"

"The wind is southeast, the wind is weak, and the direction is seventeen meters to the left!"

"The distance is two hundred feet, add five to the height!"

"Filled!"

"Report, get ready!"

Chen Ying waved decisively: "Fire!"

The fuse was ignited, sparks sputtered, and there was a chirping sound.

boom!
With the sound of a huge roar, the shells shot out quickly.

Zhu Qiyu narrowed his eyes, trying to catch the trajectory of the shell, only to see the shell whistling in the sky, like a shooting star, smashing towards the opposite target.

Boom!

Zhu Qiyu opened his eyes wide, because he saw that the shell hit the little red house in the pine forest and exploded.

Such a long distance, actually hit?

Zhu Qiyu took a deep breath, such a range and accuracy, if put on the battlefield, it is simply a magic weapon!
"Duke Yasukuni, you are amazing!"

Chen Ying had a confident smile on his face: "Thank you for the compliment, Your Highness. This is just a light cannon. Would you like to see the heavy cannon?"

Zhu Qiyu shook his head and said: "Don't be in a hurry, take me to the opposite mountain to have a look."

The hit was hit, and it could still explode, but I don't know how powerful it is.

Chen Ying nodded and said, "Your Highness, this way please!"

Zhu Qiyu was very excited, today was an eye-opener.

This cannon does not explode, has a long range, and is accurate. All the worries in my heart are swept away, and the rest is only surprises.

In his mind, countless thoughts popped up in an instant, Brother Huang is sincere, he just needs to take this thing to Annan, what Qinghua City, Shenglong City... any city can't withstand a bombardment.

The opportunity to build a career is here!
When they came to the opposite hill, the temporary pergola had already been blown to pieces.

The nearby trees were also staggered by the impact of the explosion.

If you look carefully, you will find that there are many shrapnel embedded in the trunk, which is riddled with holes.

If these trees were made of flesh and blood, they would have died long ago.

Even if the distance is longer, as long as they are hit by shrapnel, even if they are not killed on the spot, the injured will continue to consume the enemy's rations, which is a great burden for the enemy.

At this time, it is time to test the ability of the opponent's general.

If you discard them, morale will inevitably be low. Everyone is full of grief. If you don't abandon them, let them consume the rations and medicines of the troops, and even slow down the overall marching speed. It will become a bottomless pit.

With such a killer weapon, why worry about Annan's injustice!

Ancestors, I, Zhu Qiyu, will also expand the territory for Daming!
