In fact, the construction of the submachine gun is also very simple.

But it's often a very simple thing, and the most important thing is to kick the door.

If it weren't for Benjamin Goldberg, Zhao would definitely not have been able to figure it out by himself.

The gun fired, but it didn't fire continuously.

Zhao Chuanxin pulled the trigger again, but it was invalid.

When he pulls the trigger, the firing pin is pushed by a compression spring to accelerate its forward motion. As soon as the nose of the slide approached the warhead, the firing pin was inserted into the bottom of the bullet and came into contact with the fuse at the bottom. As the slider moves further forward, the firing pin ignites the gunpowder through the warhead and fires the bullet.

When a bullet is fired, recoil acts on the bolt, pushing the bolt backwards, causing the firing pin to remove the bullet from the magazine and ignite it.

This is probably the principle of the submachine gun, very simple.

But it's easier said than done.

It was when the recoil pushed the bolt that there was a problem.

All kinds of small problems emerge one after another, and the tortured Zhao Chuanxin wants to die.

Almost pressed the gourd up the scoop.

When it was almost noon, Zhao Chuanxin even wanted to smash the broken gun and didn't do it.

Benjamin Goldberg's eyes were getting brighter and brighter: "Master, I understand, I understand." ”

Zhao Chuanxin was not angry: "You have realized all morning." ”

"Ah......h

Marcus Nkrumah and Ning An have already left, and they can't even go for a walk with Mishan because they are bored of cooking, and now there are only two masters and apprentices left.

Zhao Chuanxin's obsessive-compulsive disorder is committed, and the more he fails, the more he wants to solve it.

Benjamin Goldberg, on the other hand, wanted to prove that he was right as he got better and better.

The master and apprentice were a little stunned.

"Master, try again, just once, and it will definitely work."

Zhao Chuanxin hesitated: "Then, try again?" ”

He continues to improve,

But this time it was a direct mute.

"Falke, Falke......"

Zhao Chuanxin slammed the submachine gun to the ground and stepped on it with his foot.

"Bang!"

This inferior submachine gun didn't know which tendon to draw, and suddenly went off, which startled Zhao Chuanxin.

Hurriedly looked at Benjamin Goldberg next to him and was relieved to find that he was not injured.

He silently picked up the submachine gun, put it on the table, and let out a long sigh.

Benjamin Goldberg was not afraid, but said excitedly: "Master, I understand, I understand, let's make a gun again......"

"......" Zhao Chuanxin: "Apprentice, let the teacher slow you down and realize again!" ”

When it was time for lunch, Freddie Pavit came to their master and apprentice to go back to dinner.

Seeing a strangely shaped gun on the table, he didn't care, because when he saw Zhao Chuanxin with a frustrated expression on his face, he knew that he must have failed.

This was not what he expected.

"Master, let's eat first, there's no hurry to make guns."

Zhao Chuanxin was relieved and got up to leave.

At this time, a carriage entered the manor.

It was Jesse Livermore.

He ran over in a panic.

"Ethan, something is wrong."

Zhao Chuanxin hasn't heard good news for a long time,

Molar teeth pulled a long voice: "What's the matter?" ”

"I can't recruit anyone."

"How so? Wall Street's two-legged man can't be found? ”

Jesse Livermore ignored Zhao Chuanxin's teasing: "John Morgan, that old guy is not allowed to do things for any agent on Wall Street, otherwise he will be his enemy." ”

"Which John Morgan ate the bear's heart leopard gall?" Zhao Chuanxin was furious. "Went to Wall Street today and did him."

"He was a master of asset restructuring, proficient in financial business, and presided over the establishment of a monopoly on the United States Steel Company. Morgan. ”

So Zhao Chuanxin knows who it is.

"This old immortal." Zhao Chuanxin wondered: "I didn't offend him?" ”

"I think it's because of you. We seem to be caught in a web of carefully woven intrigue designed to keep us from moving. ”

Zhao Chuanxin waved his hand: "Let's eat first." ”

At the dinner table, Jesse Livermore gushed endlessly, denouncing these conglomerates as not things, and denouncing the shameless faces of the American bourgeoisie.

But Zhao Chuanxin was silent.

It's just that for this meal, he ate very little.

After the meal, he smoked a cigarette in his chair.

Miao Cuihua came behind him and pressed his shoulder: "Don't be discouraged, it's a big deal, let's go back to China and start all over again." The worst is the worst, so I accompany you to farm. I used to farm, and it was only in the past two years that the cocoons on my hands receded. ”

To say that in this era, the person who knows Zhao Chuanxin best is undoubtedly Miao Cuihua.

Zhao Chuanxin pulled the little hand on his shoulder: "I'll take a look?" ”

Sure enough, there are no more calluses in the palms.

In the past two years, it has been well maintained, white, tender and soft.

"Is it pretty? Go back to the house? ”

"Hehe, I still have to make guns."

Zhao Chuanxin fled.

He found that the gap between the times in his heart was getting smaller and smaller.

That little line of defense has collapsed, and the last insistence is crumbling.

Miao Cuihua saw him walking out with the snot baby and the foreigner named Jesse, smiled, and instructed the servants to clean up the kitchen.

Zhao Chuanxin said as he walked: "Since the weapon workshop can play the trick of Ming Xiu Plank Road and Dark Chen Cang, then financial operations can also be done." ”

Jesse Livermore is smart and doesn't think about it.

But if you find another agent, what else do you want him to do?

Zhao Chuanxin saw through his thoughts, and when he saw that he was silent, he said: "Thomas W. Lawson, I think that old boy has two hits. I can lend you an extra amount of money, which is enough for you to make a good profit. If you do big things, don't always dwell on the details. ”

Jesse Livermore finally smiled: "Okay, but his means are limited, and he is more inclined to intrigue and intrigues, which can sometimes be bad." ”

"In his name, but he is the auxiliary, and you are the master. I don't care about anything else, I just want to make money. ”

"I know how to do it."

After temporarily solving the trouble and sending Jesse Livermore away, Zhao Chuanxin came to the table again, helpless against the broken gun.

Benjamin Goldberg was 10,000 times more active than he was in school, and he had been sitting there waiting for a long time.

"Master, I promise, I have realized it, and I will definitely succeed this time."

"Lend you good words."

Zhao Chuanxin re-cut and polished parts and started a new journey.

What he fears most now is Benjamin Goldberg, telling him to "get enlightened".

Enlightenment means starting over.

After all, I have the experience of doing it once, and it is easy to do it again.

The original drawings of the submachine gun have been changed beyond recognition by the master and apprentice.

In this era of the hegemony of the "big bolt" and the machine gun, it is common to see many melon-eating riflemen on the battlefield, shooting unhurriedly.

It was a lively day for a long time, and there were zero deaths and injuries.

Why is Zhao Chuanxin called the God of War?

He always had more than one enemy, and the enemy usually suffered heavy casualties, perhaps more than on a battlefield where hundreds or thousands of men were firing at each other.

That's why the enemy is afraid of him.

If there is a submachine gun, whether it is him or the insurance team in Lugang Town, it will rewrite the situation of the war.

And the submachine gun is nothing more than the first step.

It was imperative to invent submachine guns.

Even if it is not suitable for large-scale battlefield at present, but Zhao Chuanxin uses it himself, it must be developed.

He put away his impetuosity and had a serious discussion with his apprentice.

"Master, the firing pin here, I have to use a stronger and more reliable material, otherwise it will always fail."

Zhao Chuanxin set his sights on beryllium copper.

Beryllium copper has high strength, hardness, and corrosion resistance, which is better than high-carbon steel, and of course, more expensive.

Zhao Chuanxin gritted his teeth: "Fake, this time our gun head, jam plate, roller, hammer, bore, trigger, rate of fire selection rod, but all those that have to be rubbed often use beryllium copper." ”

It may not be possible to see the cost of a few guns, but if there are more of them, the cost will rise sharply.

He didn't know how much impact his decision today would have on the future military fan collecting community......

This time, six right-handed rifling lines were carved into the inner chamber.

The thickness of the gun head and the size of the roller were all discussed repeatedly by the master and apprentice before the conclusion was made.

Finally, Zhao Chuanxin began to assemble.

After installing all the parts, Zhao Chuanxin took a deep breath.

I tugged on the handle above, but it was still a little frizzy.

There are three types of lube on the table.

One is a lightweight lubricant for cars and carriages, which can also be applied to manual bolt rifles.

One is high-temperature lubricating oil, which is produced by John Rockefeller's oil company and is specially used for high-temperature and high-pressure machinery.

Finally, there is gun oil, which sounds professional, but in fact it is made of animal fat, and it will solidify at low temperatures.

Zhao Chuanxin thought about it, first disassembled the gun, dipped his hands in high-temperature lubricating oil without being dirty, and began to apply the parts, and carefully wiped them with a coarse cloth.

It is very particular to rub the oil on the gun, because at this time, no matter what kind of lubricating oil, it is not as good as the chemically synthesized lubricating oil in later generations.

Too much oil can lead to carbon build-up and slow down the burning of gunpowder.

Too little oil will not have the effect of lubricating the gun.

Zhao Chuanxin understands this kind of thing, and there are a lot of things.

After processing, Zhao Chuanxin reinstalled the parts.

This time he did it very seriously,

Because he wasn't sure if he would be able to maintain his patience and continue his research if he failed this time.

Anything is the most difficult when you take the first step.

Therefore, he has a sense of ritual and waits for the final practice.

He put on his Fortitude armor, pulled on his skull mask, loaded his bullets, and tugged on the handle.

Taking a deep breath, under Benjamin Goldberg's somewhat nervous gaze, Zhao Chuanxin pulled the trigger.

Sudden Sudden Sudden ......

With the tongue of fire spewing out of the muzzle, and with the pouring of metal frenzy, Zhao Chuanxin's hanging heart was also put down.

He let loose the gloom of the day.

Benjamin Goldberg happily jumped up from his chair.

He thought that fantasy could make him happy, but today he realized that it turned out that fantasy became reality, and it was the most fulfilling!

Inside the villa, Freddy Pavit is working on papers.

His pen was free, his handwriting was well laid out, and his lines were smooth and graceful, and it was at this time that Spencer's cursive writing was popular in the United States and England.

Suddenly, he heard a series of rapid gunshots.

The sound of heavy machine gun gunfire was calm and muffled.

And this continuous gunfire was rapid and sharp.

It's like a dense and orderly pistol sound.

Freddie Pawit's heart moved, and he stood up in disbelief: "Impossible, isn't it, isn't it ......?"

He knew what kind of gun Zhao Chuanxin wanted to study.

At this time, John Browning, the most famous weapons design expert in the United States, made it clear that this was impossible.

Even experts say this, how can they let Zhao Chuanxin be a layman and add a child who has not grown all the hair to create it?

He threw the pen on the table and walked out quickly.

Also coming out were Ning An, Li Shutong, and Miao Cuihua......
