Well, at this time, Boss Luo had no choice but to show his hole cards, and he smiled and said to the group of young people:

"Well, the excitement will be there soon, the reason why I say this to everyone is mainly to ask everyone to do a favor, if everyone is willing to help with these five machines to rifle the barrel of the flintlock pistol today, I guarantee that the excitement will be seen this afternoon......"

Damn, it's pulling people to help with the work?

I'll just say, it's not that simple, Nima has come full circle, and Boss Luo is waiting for us here......

However, the crowd did not complain too much about this, but talked about the seemingly simple equipment with a base and basic structure made of cement and wood, and the crew also noticed that there were several flintlock pistols with thick and long barrels next to them.

"Are you pulling us to work for your old man?"

"Okay, we know, Brother Hou's escort team needs weapons, and the time is tight and the task is urgent......"

Although the crowd complained slightly, they quickly changed the topic, because these rifled devices did look very attractive.

"Which of you is going to try it?"

"Me!"

"I'll do it too!"

Peng Qiang and Hu Xiaolin were the first to stand up and respond to Boss Luo's invitation.

Then the two of them began to slowly rived the barrel of the gun under the demonstration and teaching of Boss Luo, and there was a group of melon-eating crowds next to the two of them watching.

"Uh...... Is it the rifling that was pulled with this screw? ”

"Looks like a simple operation."

"Is it so simple to get a rifling machine?"

"yes, I thought it was complicated......"

"This equipment looks simple, but it is really difficult to do, without a certain foundation of gold processing, it is impossible to make this seemingly simple equipment!"

"Well, that's right, I can see that just the manufacturing of this screw is the key, if there is no really strong processing ability, people in this era can only watch, and they can't do it at all......"

"Well, the rear-loading flintlock pistol, it looks like we can really make it!"

"It's exciting!"

"Yes, rifled flintlock pistols seem to be quite advanced weapons in this era."

Boss Luo patiently waited for the onlookers to finish their discussions, and then picked up an iron pipe and said to everyone:

"There's a ready-made barrel here, the barrel of the Dutch flintlock pistol you brought back from Macau."

Boss Luo said that he took the barrel of the gun to show everyone, and sure enough, it was indeed removed from the Dutch flintlock pistol.

"We're going to change this firearm, and one of the items is to rifle the barrel, see? The cutting tools on the screw are also made by heat treatment using the iron you brought back. ”

Boss Luo said and fixed the barrel on one of the Iowa rifling machines, aimed the screw at the mouth of the barrel, and a steel wire passed through the barrel and was tightened and fixed on the two support points, and then began to demonstrate the rifling operation to the Peng Hu and the others next to him again.

"Is it easy?"

"Just pulling back and forth?"

The onlookers made comments while watching Boss Luo's operation.

"Okay, there are still two rifling machines empty, which of you want to try it?"

At this time, Boss Luo stopped what he was doing, looked up with a smile and asked everyone.

"Can we really?"

"Since Peng Qiang and them can all do it, let's try it too......"

"Can you tell me more about the operation essentials?"

"It's very simple, as long as you put on the cutting tool, fix it, and use it evenly, it's very easy."

Boss Luo responded to everyone with a smile.

"It seems that Boss Luo is really too busy to pull us to work......"

"Yes...... But don't force it, I know you're tired too......"

Boss Luo said to everyone while pulling back and forth.

"Then I'll try!"

"I'll try it too, it's fun to watch......"

"Since they were all deceived by Boss Luo, it doesn't seem good to turn around and walk away......"

"Let's all try to pull it, let's say okay first, don't blame us if it's broken!"

"Don't worry, it won't break."

"Boss Luo, that's it?"

"That's it, yes, yes......"

So Boss Luo's mechanical repair shop was very lively, and a total of more than a dozen people helped work here until four o'clock in the afternoon.

……

Time: Half past four in the afternoon, January 6, 1658.

Location: On the beach near the mouth of the Moon River.

"Now I'm going to show everyone the excitement - bell!" Australia's 1657 rifle debuts! ”

At this time, a group of young people were surrounding Boss Luo and Teacher Zhao, the former holding a rifle with a long barrel in his hand, and was excitedly introducing to the onlookers.

"Boss Luo, why is it called 1657? Isn't it 1658? ”

At this time, someone in the crowd of onlookers interrupted Boss Luo's speech.

"Because this rifle was designed and finalized by us at the end of last year."

After Boss Luo replied succinctly, he weighed the rifle a few more times with both hands and continued:

"At noon, a few of you helped out in the machinery factory, and you also witnessed this commemorative historical moment!"

Looking at the knowing smile of someone in the crowd, Boss Luo continued:

"This rifle is the first single-shot compound flintlock rifle produced by our mechanical group, with fixed ammunition at the rear, a total weight of more than six kilograms, a total length of 1.6 meters, not counting bayonets.

Please note that the caliber of this barrel is 14 mm, it seems that the caliber of the barrel of this era is quite large, so the projectile is heavier and more powerful, according to theoretical estimates, the reliable range of the gun should be 150 meters to 200 meters......"

"Hey...... Boss Luo, it seems that there is no such thing as 'reliable' range in the performance data of firearms, right? ”

At this time, Ren Ke in the crowd complained.

"Well, you're right, but now there's a scientific way of saying it's 'effective and accurate dispersion distance', which is commonly known as 'reliable range' in my case."

"Okay, please keep ...... old"

"Well, everyone knows that this gun is actually made by the Dutch flint ** that you bought back from Macau, but you just made a big move and changed it for the devil.

First of all, a total of six rifling wires were pulled out of this barrel.

Second, we have modified the medicine pool and added a tie-type opening and closing slot, which can just hold a paper shell fixed bullet.

Thirdly, we have strengthened the barrel and improved the firing device......"

At this time, Boss Luo introduced while demonstrating, and then pulled away a small metal handle on the back of the gun.

Seeing this, everyone subconsciously took a step back, consciously keeping a certain distance from Boss Luo, Boss Luo was slightly happy when he saw this, and he explained in a slow tone:

"Don't worry, the barrel is reinforced, it won't explode, in addition, please trust our processing accuracy, the air tightness of this gun after improvement is also good......"

After Boss Luo said this, he raised the gun a little higher so that everyone could see it clearly, and raised his voice to continue to introduce:

"Look, everybody! Here's how it works, pull the leash from right to left, exposing the medicine pool......"

Boss Luo picked up the gun and pointed it to the sea, pulled a bolt on the back of the barrel with a bang, revealing a groove, and then turned back and continued to say to everyone:

"Everyone, please look here, this groove in the rear of the barrel is used to load ammunition......"

"This is rear-loading ammunition!"

"Sure enough, it's much more convenient, and you don't have to take an iron bar to stab and stab the time."

"Are the ammunition and metal projectiles wrapped together?"

At this time, the crowd finally gathered around curiously, and began to talk about it.

"That's right! Ladies and gentlemen, this is the ammunition that Mr. Zhao and they just made by hand - paper shell fixed ammunition! ”

As he spoke, Boss Luo took out a tube from a cardboard box on the ground, and wrapped the round metal projectile in front of it.

Boss Luo picked up the ammunition and put it in the groove and compared, well, the size is just right.

"That's what it means to have a duplex after the rear......"

Many people nodded when they saw this, obviously they were not military fans, and they didn't understand some clues until now......
