Datang: God-level Choice

All of a sudden, even Li Er is interested

The Tang people were good at archery in the first place. From the beginning of the military system, there was only one bow and arrow in each hand. In the army, there were countless outstanding archery skills. Every time a routine archery competition, a few talents would emerge. Those who could be selected into the military academy were even more so. the best among them

And now, to select a thousand elites from these academies that are good at archery, it really makes everyone very curious.

Could it be that King Qin wanted to realize the sniper he said last time, training a thousand archery masters to snipe at the opponent's middle and high-level officers, but the best iron tire bow of 623 has a range of [-] meters. The distance, with the strength of the Tang Dynasty's army, it is enough to charge and crush directly, why is it so troublesome?

"Your Majesty, what is your Highness Prince Qin selling?"

Cheng Yaojing came to Li Er's side and asked in a low voice

"I don't know, I'm being kept from the whole bastard son-in-law just like you!"

Li Er took a look at the pit lane in annoyance

"Ah, Your Majesty, you don't know either."

Cheng Yaojing's exclamation made the veterans even more curious, but Qin Huaidao didn't say anything, and there was nothing they could do.

"Don't you say that you are very free, I will select a thousand elites for this dean within three days, and see you at the shooting range of the Military Academy in three days!"

"I'll go to the Academy of Military Sciences first to follow up on the progress of the research and development."

After Qin Huaidao finished speaking, he immediately ran away, and immediately made Li Er and a group of old soldiers jump in anger.

"Your Majesty, do we want to follow?"

Old Yuchi said blankly, "Forget it, before the completion of the research institute, there are only parts and drawings. If this kid doesn't talk about it, who of you can understand?"

Li Er analyzed: "You should choose the thousand people this kid wants first. After three days, everything will be understood."

"In my opinion, these thousand people will definitely be related to the Tianzhu battlefield, which is enough to change the entire battle situation. Otherwise, this kid will not be able to sell things like this, and it will shock us."

I have to say that Li Er is very fond of Qin Huaidao's son-in-law. After some analysis, a group of veterans and ruffians are very convinced, and they can't find any faults.

In desperation, the old soldiers and ruffians could only forcibly hold back their curiosity, and honestly began to select people from the academy. They were also looking forward to the new invention that will be born in three days.

In the Academy of Military Sciences, Mo Yi, Zhou Xin and others were overjoyed when they saw Qin Huaidao's arrival.

Under the guidance of Qin Huaidao, and after many practical applications and improvements, the Academy of Military Sciences has already formed a set of effective research and development mechanisms. It is only half a day after looking at the drawings, but various trial production work has already begun.

In the process of practical application, they also encountered a lot of problems, and they were thinking about how to ask Qin Huaidao for advice.

One of the most urgent problems is the barrel of the fire gun, which is the core of the entire fire gun. It must not only ensure the integrity of the rifling, but also withstand the wear and tear of multiple firings without destroying the original structure of the barrel. Strength, it doesn't seem to be difficult, but in actual operation, it stuns the best craftsmen of the scientific research institute

In the end, the craftsmen could only follow the experience of making artillery before, and suggested to thicken the barrel and enlarge the caliber a little, so that the whole barrel can be made stronger, but in this case, the whole design must be completely changed. The workload simply cannot be completed in three days

"You mean, the rifling that has been pulled out is not qualified enough, and the degree of wear is not enough?"

Qin Huaidao picked up a gun barrel drawn by hand by craftsmen and looked at the sun, and soon discovered the problem.

This gun: The rifling of the barrel is pulled out by hand with a tool similar to an auger after the barrel is formed. Although the depth is not enough, the shape is very regular, which shows the exquisite craftsmanship of the craftsman. degree

The gun made in this way is not to say that it cannot be used, but because the depth of the rifling is not enough, every time the gunpowder is fired, it will be worn a little, and it will be easily ground, and the service life will be seriously insufficient. It can be used for thousands of rounds. Yes, maybe one or two hundred rounds are gone now

With the experience of artillery, the craftsmen are very clear that rifling is the foundation of ensuring accuracy. With the technology of Datang today, smoothbore guns cannot guarantee accuracy at all. Whether it can hit a few hundred meters away is purely random.

The artillery can also rely on the method of multiple simultaneous firing to make up for the lack of accuracy, and if the accuracy of the fire gun is too poor, most of the time, it is not even as easy to use as the iron tire bow.

Of course, if you wait for the steam machine on the drawing to be completed, these are not problems, but this kind of large machine is at least a month faster, and the craftsmen can't wait.

"Your Highness is disappointed!"

Mo Yi and Zhou Xin bowed their heads ashamed and said.

"It doesn't matter, you have performed very well, but you just need to change your thinking."

Qin Huaidao said with a smile: "Fire guns are not artillery pieces. Since the barrel can't be rifled after it's made, you can first pull the rifling on the steel skin, and then roll it into a barrel."

Mo Yi, Zhou Xin and others were overjoyed immediately

Qin Huaidao is right, their craftsmanship is indeed not to be underestimated, but they are often limited by the limitations of the times and lack the guidance of innovative thinking.

Today, Datang's steel-making technology has reached a very high level thanks to Qin Huaidao's drawings and the continuous learning and improvement of craftsmen.

High-strength special steel, although the output is still relatively low, but the quality is already very good

In the scientific research institute, in order to forge lighter and cheaper steel guns, there are many special steel stocks, and the steel of one gun is enough to make thousands of them, and the barrel is here.

According to Qin Huaidao, it is indeed very feasible to pull out the rifling on the steel skin and then roll it into a barrel.

Mo Yi and Zhou Xin immediately

Arrange people to get started

Chapter Five Hundred and One: Ask the King of Qin

(The first one! Ask for full order!)

The so-called rifling looks like a spiral shape, but if you use the method of pulling the rifling first and then rolling it up, in fact, as long as you draw a straight line diagonally above the iron sheet, and then roll it flat, the original straight line will naturally become Spiral up

Such an action is not very difficult for a scientific and technological research institute with a large number of Mohist descendants who are very skilled in manual work.

After spending half an hour and a few sheets of steel, a craftsman from the Mo family pulled out a relatively qualified rifling.

"Very good, give this craftsman a hundred bonuses!"
