Although as soon as Sun Yuanhua finished saying this, he immediately understood that something was wrong with his words.

How can you say that Your Majesty can't do it?

Your Majesty will always do.

"Your Majesty, the minister made a mistake for a while, please forgive the emperor, but this rear-loading artillery is indeed unsafe."

"There is a big problem with the airtightness of the rear-loading artillery, and I am afraid that if this kind of artillery is equipped, the cannon will not be able to hit far."

"When the time comes, we won't have any advantage in fighting the cavalry of Jiannu."

"Wouldn't this be a waste of effort, and a lot of silver taels were wasted."

Of course, Zhu Youxiao didn't believe him.

Because Zhu Youxiao knew very well that the rear-loading gun was the future of artillery, and the rate of fire of the front-loading gun was too slow.

"You can take a look back first, and then talk about what I think of this rear-loading gun."

Sun Yuanhua took a closer look and found that there was indeed something different.

The artillery proposed by Zhu Youxiao was indeed different from all the artillery he had ever seen.

But Sun Yuanhua's idea is deep-rooted.

The shaft knows a fart artillery.

Of course, he didn't dare to say this, and if he said it, it would not be a matter of losing his head, at least it would be a neat family.

However, he found that the bolt of the artillery proposed by Zhu Youxiao was very magical.

Sun Yuanhua had never seen such a bolt.

"Could it be that the reason why Your Majesty wants Weichen to create this kind of rear-loading cannon is the subtlety of this cannon bolt?"

Zhu Youxiao nodded and said, "That's right, it's this cannon bolt." ”

"As long as you can make this thing, then the problem of the airtightness of the artillery can be solved."

That's right, Zhu Youxiao's rear-loading gun used a horizontal wedge bolt for the bolt.

How did the cavalry in the last years of the Qing Dynasty be overturned by British soldiers?

That's largely thanks to a cannon called the Armstrong Cannon.

This Armstrong gun is native to the United Kingdom and is a breech-loading rifled gun.

Before his appearance, it was almost all the world of breech guns.

During the Crimean War in 1854, Armstrong designed an experimental 3-pounder breech-loading rifled gun.

The design was successful in both range and precision, and was adopted by the British government in 1858.

Therefore, the Armstrong gun is the first rear-loading rifled gun in the world.

It has the advantage of a breech gun that it does not have, that is, it can be quickly reloaded from the rear.

Only because this gun used a vertical wedge gun bolt "Armstrong Screw".

In addition, the Armstrong gun is easier and faster to reload.

In addition, the inner wall of the barrel of this kind of gun is engraved with spiral rifling, and the conical shell fired can rotate at high speed, so that the gun has higher accuracy and a longer firing range than the smoothbore gun.

However, all of them are round, solid shells.

This kind of round iron cannonball, in fact, usually uses ricochet to kill and injure the enemy, that is, using the principle of "hitting the water", let the spherical solid cannonball bounce on the flat ground, and sweep the enemy's dense infantry column at high speed.

It doesn't sound like it is powerful, but where this cannonball passes, it is a passage made of flesh and blood, which is still very cruel and abnormal.

The current Hongyi cannon generally uses this method to kill and injure the enemy.

At that time, Zhu Youxiao would have to get the cylindrical shells out first.

But it's not funny, and it involves fire and stuff like that.

But in fact, he can also make this kind of thing, and this method is not difficult at all, even with the level of science and technology in the Ming Dynasty, it is not difficult to cast it.

The first time this Armstrong cannon was used was in the Second Opium War.

The Anglo-French forces, with their Armstrong guns, quickly captured the Dagu Fort in Tianjin, which used old front-loading smoothbore guns.

The 35,000 Mongolian Eight Banners cavalry of the Qing Dynasty general Seng Greenqin was defeated and annihilated by the Armstrong field artillery of the British and French forces in the Battle of Bali Bridge.

According to the Englishman McGee, "How We Got Into Peking: An Account of the Chinese Campaign in 1860."

In the battle of Tanggu Fort, 12 Armstrong cannons of the British army opened fire at a distance of 900 meters from Tanggu Fort, and engaged in an artillery battle with the artillery of Dagu Fort.

The firing accuracy of this Armstrong cannon reached an unprecedented level, and almost all of the shells fired by them accurately hit the artillery of the Qing army.

In the later battle of Tongzhou Bali Bridge, the Armstrong cannon played a surprising record.

According to George Kruller's book "The March to Beijing", the 35,000 Mongolian Eight Banners cavalry led by the monk Gelin took the lead in attacking the British army.

At that time, these Mongolian Eight Banner cavalry of the Qing army behaved very bravely and fearlessly in the face of the British army, believing that as long as they could break through the short damage of the enemy's artillery, they could cut off the British army's head after head.

The British artillery began to fire at the Qing cavalry, allowing the cavalry to see the power of artillery that they had never seen before.

The British gunners fired slowly, and each Armstrong cannon exploded between the Qing cavalry, knocking down a group of Qing cavalry.

Subsequently, the cavalry of the Qing army was directly blinded by this powerful Armstrong cannon, and the two British Sikh cavalry regiments immediately launched a terrible slaughter of the Qing army.

At this time, more than half of the 35,000 Qing and Mongol cavalry of the Eight Banners suffered casualties, while the 10,000-strong Anglo-French army had only five killed and 40 wounded.

This kind of artillery can't even withstand the cavalry of the Qing army, but can the current Jiannu cavalry withstand it?

Zhu Youxiao thought it was obviously impossible.

Therefore, the artillery design drawings taken out by Zhu Youxiao are actually the design drawings of this kind of Armstrong gun.

Even the fire ** paper he took out, if it can be cast, will definitely be more powerful than the original Armstrong cannon.

Because although the Armstrong cannon at that time was very powerful, it was not completely without shortcomings.

Although the Armstrong cannon was extremely lethal, it was not very reliable in battle due to new technologies such as rifling, leaded shells, and rear-loading blocking.

At the same time, the attack range of only 900 meters is too touching.

Even the Hongyi cannon, which is so backward like theirs now, can hit three miles.

In addition, this cannon has other drawbacks, such as the fact that it is too expensive to build, and its bolt settings are too difficult to manufacture.

With the difficulty of manufacturing this kind of cannon latch, at least with the technology of the Ming Dynasty, it is impossible to cast it.

At least the precision of the Armstrong screws is simply not solved, and there is no way to put it into use.

This truth, called the Armstrong Cannon, requires a simpler, faster, and safer cannon latch that even Ming Dynasty technology can make.

Because even Britain stopped making Armstrong guns in 1864 and continued to use the ancient and reliable breech guns.

It wasn't until 1880 that Armstrong improved the Armstrong gun again, introducing the French technology of the broken threaded gun latch, which made it possible to reload quickly.

Therefore, from 1880 onwards, the British army once again equipped the breech Armstrong gun in the army.

However, this kind of bolt is still too complicated, and Zhu Youxiao has no way to get it out on the basis of the current manufacturing level.

At the same time, the German Krupp company invented a wedge bolt with better air tightness.

This cannon bolt is the real artifact!
