Become a feudal king from today

"Your Highness, please give me your instructions. Read М"

At the entrance of the Science and Technology School, Wang Ying handed over to Zhao Xu.

"Last time, I asked you to sharpen the barrel of the artillery, which greatly increased the power and range of the artillery." Zhao Xu said slowly.

"Indeed." Wang Ying nodded, and he still admires King Yan for this matter.

This transformation made the artillery of the royal army much better than the artillery sold to the powerful clan.

It is said that the artillery made by Beidi is only half as good as the artillery they sold to powerful people.

In this way, if Beidi starts a war with Yanzhou again, Beidi will definitely suffer a big loss.

"This time, I asked you to modify the flintlock guns and add rifling to them." Zhao Xu's eyes narrowed.

Since the barrel of the flintlock was drilled out by itself, he didn't need to cut it again at all.

The only way to increase the range and power of a flintlock was to rifle the musket.

"Rifling?" This was the first time Wang Ying heard this term. Like many times in the past, he was confused.

Zhao Xu then explained the concept of rifling to him.

At the moment, the flintlocks they use are called muzzle-loading muskets.

Because it is a smooth bore, when the bullet is fired, it will inevitably hit the inner wall of the gun chamber and then fly out.

During the impact process, it is impossible to determine where the bullet's trajectory is pointing.

This is why smoothbore flintlocks can only rely on dense formations to increase their lethality.

A single fusilier is less of a threat than an archer.

But carving rifling on the inner wall of the gun bore is different.

Due to the rifling effect, the bullet moves in a spiral after being fired.

This will stabilize the trajectory of the bullet, which will not only improve accuracy but also increase shooting distance.

"The rifling etched into the wall can have such a magical effect?" Wang Ying was surprised.

Zhao Xu nodded, "Facts speak louder than words. Just make a rifled gun according to my request."

After that, he squatted down and drew something like a hook on the ground.

"This thing is called a broach. It is a tool just like the boring tool of the hydraulic boring machine. After you go back, you can polish the broach first, and then etch the rifling. As for how to etch the rifling and what the spacing is, I will let you know later. Someone will send it to you." Zhao Xu continued.

"Yes, Your Highness." Wang Ying stared at the pattern on the ground, then stretched out his hand to smooth it out so that no one would notice it.

After explaining the matter, Zhao Xu turned around and returned to the palace.

In the study, he took out a pen and drew a rifling diagram of the inside of the barrel.

Generally speaking, the larger the caliber of the gun, the more rifling it has.

The caliber of the flintlock gun was still very large, so he drew six riflings.

And contemporary machine guns only have eight riflings.

In just one cup of tea, six rifling lines appeared on the drawing in front of Zhao Xu.

He also marked the distance between the riflings, which is the twist of the rifling.

In this way, when Wang Ying pulls the rifling, he only needs to pull according to this distance.

Then, he wrote down the steps for rifling.

Since the rifling is spiral, you cannot pull it straight and straight when pulling the rifling.

Instead, the broach should be pulled diagonally, and the six rifling lines should be kept parallel. After completion, the overall distribution will be spiral.

After the painting was completed, Zhao Xu asked someone to send it to Wang Ying.

Waiting for the birth of Dasong's first rifled gun.

in contemporary times.

Rifled guns appeared in the fifteenth century, when they were called rifles.

In the seventeenth century, the Danish army was first equipped with rifled guns.

However, during this period, the armies of most countries were still unwilling to equip rifled guns on a large scale, and only allowed a small number of skirmishers to use rifles to harass enemy arrays.

This is not because other countries are stupid, but because the existence of rifling reduces the sealing of the gun bore, so the bullet size can only be increased.

The consequence of this is that loading becomes difficult, sometimes even requiring the use of a hammer.

However, due to the superiority of rifled guns, during the American Revolutionary War in the 18th century, the American militia was still equipped with a large number of rifled guns.

It was not until the mid-19th century, with the emergence of the Minie rifle, that the smoothbore gun was officially eliminated and completely replaced by the rifled gun.

Because the special bullet of the Mini rifle solves the shortcomings of the rifled gun.

This bullet is a tapered lead bullet that is easy to load and has a hollow base.

When the gunpowder explodes, it will first enter the bottom, expanding the bullet and protecting the seal.

This time, Wang Ying was asked to improve the flintlock gun, and he planned to use this conical bullet.

In the mid-19th century, the Minie rifle had a range of more than 900 meters and could maintain accuracy within 500 meters.

But at that time, the gunpowder used in the flintlock gun was no longer black powder, so it was more powerful.

At the moment, he does not have the ability to create gunpowder more powerful than black powder.

But even so, the range of the improved flintlock gun has been increased to 400 meters, and it is still no problem to maintain a certain accuracy within 200 meters.

Such a front-loading rifled gun is enough to cause Beidi people to suffer a lot.

This is why he agreed to compete with Beidi.

Confidence comes from this.

Although the royal army lacks mobility and cannot expel Beidi on the grassland, they can definitely defeat Beidi by relying on the bastions and Yanguan.

Thinking of this, he felt a lot more at ease.

"Your Highness, Captain Bai Shang would like to see you." While Zhao Xu was thinking, Feng'er arrived at the door of the study.

"Bai Shang?" Zhao Xu frowned.

Except for Chang Wei, other generals rarely asked to see him alone.

Motioning Feng'er to let him in, Zhao Xu sat in front of the desk and waited.

After a while, Bai Shang strode to the study.

After a salute, he said: "Your Highness, I am not here for myself, but for Yang Zhen's request."

"Yang Zhen?" Zhao Xu was stunned.

Bai Shang was a little embarrassed, "In theory, Yang Zhen is just a soldier now, and his private affairs do not need to disturb Your Highness, but..."

At this point, he did not say anything.

Zhao Xu understood what Bai Shang meant. Yang Zhen was indeed a little special now.

After all, in addition to being the defeated general of Ningjin Dusi, he was also the son of Yang Feng.

So he said: "It doesn't matter, he has something to say to the king."

"Yang Zhen asked Your Highness to write a memorial to protect General Yang Feng. He said that the Northern Expedition was a great defeat, and the ministers of the powerful families such as Dou Wei would definitely put the blame on his father." Bai Shang said.

Zhao Xu suddenly frowned when he heard this.

He had forgotten about this matter.

Although the peace talks were successful this time, the aftermath of the failure of Beidi seemed to be still floating.

He needed to pay attention to what would happen in the capital, including the matter of Yang Feng.

"Fortunately you came, otherwise I would have been careless. I will submit a memorial to protect General Yang Feng." Zhao Xu said.

In his opinion, Yang Feng was indeed loyal.

However, he could not deny that Yang Feng, like Mo Di, was the only good general left in Dasong.

If he was framed and died, it would be really unbearable.

Thinking of this, he immediately drafted a memorial and sent it out.

Then he called Xu Ke and asked him to keep a close eye on Beidi and the capital.

After only eight days, Xu Ke sent him a piece of information that surprised him.
