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

But it is often a very simple thing, and the last step is the most critical.

Without Benjamin Goldberg, Zhao Chuanxin would definitely not be able to do it himself.

Although the gun fired, it failed to fire continuously.

Zhao Chuanxin pulled the trigger again, to no avail.

When he pulls the trigger, the firing pin is pushed by the compression spring to accelerate its forward movement. When the front end of the slide approaches the bullet, the firing pin is inserted into the bottom of the bullet and comes into contact with the fuse at the bottom. As the slide moves further forward

Move, the firing pin will ignite the gunpowder through the warhead and launch the bullet.

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

This is probably the principle of a submachine gun, it's very simple.

But it is easy to say, but difficult to do.

The problem occurred when the recoil pushed the bolt.

Various minor problems emerged one after another, tormenting Zhao Chuanxin to the point of death.

It’s almost like pushing the gourd and lifting the gourd.

When it was almost noon, Zhao Chuanxin even wanted to smash the broken gun and give up.

Benjamin Goldberg's eyes became brighter and brighter: "Master, I understand, I understand."

Zhao Chuanxin was angry: "You have been enlightened all morning."

"Ah this..."

Marcus Nkrumah and Ning An had left early, and they were too bored to even eat. They went for a walk with Mi Shan, and now only the master and apprentice were left.

Zhao Chuanxin suffers from obsessive-compulsive disorder. The more something goes wrong, the more he wants to solve it.

But as the ideas in his mind became more and more perfect, Benjamin Goldberg wanted to prove that he was right.

The two masters and apprentices were a little confused.

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

Zhao Chuanxin hesitated: "Then, try again?"

He continues to improve,

But this time it was a misfire.

"Farke, Farke..."

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

"Bang!"

This inferior submachine gun suddenly went off fire, which shocked Zhao Chuanxin.

I quickly looked at Benjamin Goldberg next to me 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 happily: "Master, I understand, I understand, let's make a new gun..."

"..." Zhao Chuanxin: "Disciple, let me take a moment and you will realize it again!"

At lunch time, Freddie Pavitt came to see their master and apprentice go back to eat.

When he saw a strange-looking gun placed on the table, he didn't take it seriously, because when he saw the frustrated expression on Zhao Chuanxin's face, he knew it must have failed.

This was not what he expected.

"Master, let's eat first. We are not in a hurry to make guns."

Zhao Chuanxin felt relieved and stood up to leave.

At this time, a carriage entered the manor.

The visitor is Jesse Livermore.

He ran over in a panic.

"Ethan, something is wrong."

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

He grinded his teeth and said in a long voice: "What happened again?"

"I can't recruit anyone."

"What do you mean? The two-legged person on Wall Street can't be found?"

Jesse Livermore ignored Zhao Chuanxin's teasing: "John Morgan, that old guy said that no broker on Wall Street is allowed to do work for me, otherwise he will be his enemy."

"Which John Morgan has the heart of a bear but the guts of a leopard?" Zhao Chuanxin was furious. "I went to Wall Street today to kill him."

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

So you know who Zhao Chuanxian is.

"This old man is immortal." Zhao Chuanxin wondered: "Didn't I offend him?"

"I think it's because of you. We seem to have fallen into a conspiracy network that has been carefully woven to make it difficult for us to move forward."

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

At the dinner table, Jesse Livermore talked endlessly, criticizing these consortiums as nothing, and denounced the shameless faces of the American bourgeoisie.

But Zhao Chuanxin remained silent.

It’s just that he ate very little during this meal.

After the meal, he smoked a cigarette on the chair.

Miao Cuihua came behind him and rubbed his shoulders: "Don't be discouraged. The worst we can do is go back to China and start all over again. The worst case scenario is that I will accompany you to farm. I used to farm, and it was only in the past two years that the calluses on my hands receded."

”

In this era, the person who knows Zhao Chuanxin best is undoubtedly Miao Cuihua.

Zhao Chuanxin pulled the little hand on his shoulder: "Let me see?"

Sure enough, there are no calluses on the palms.

It has been well maintained in the past two years, and it is white, tender and soft.

"Does it look good? Let's go back home and watch it?"

"Haha, wait for now, I have to make a gun."

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 been defeated, and the final hold on is crumbling.

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

Zhao Chuanxin said as he walked: "Since the weapons workshop can play the trick of building plank roads in the open and concealing the warehouse, then financial operations can also be done."

Jesse Livermore is very smart, it’s not like he hasn’t thought about this.

However, if you find another agent, what else do you need him to do?

Zhao Chuanxin saw through his mind, and when he saw that he was silent, he said: "Thomas W. Lawson, I think that old boy has a lot of trouble. I can lend you an extra sum of money, which is enough for you to make a huge profit."

If you want to do big things, don’t always get hung up on the details.”

Jesse Livermore finally smiled: "Okay, but his methods are limited and he prefers conspiracy, and sometimes he does bad things."

"It will be done in his name, but he will be the auxiliary and you will be the main one. I don't care about anything else. I just want to make money."

"I know how to do it."

After temporarily solving the problem and sending Jesse Livermore away, Zhao Chuanxin came to the table again, unable to do anything with the broken gun.

Benjamin Goldberg is 10,000 times more active than going to school and has been sitting there waiting for a long time.

"Master, I promise, I have enlightened and I will succeed this time."

"I'd like to lend you some good words."

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

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

Enlightenment means starting over.

After all, I have done it once, so I feel comfortable doing it again.

The original blueprint of the submachine gun has been changed beyond recognition by the master and apprentice.

In this era where "big bolts" and machine guns dominate, you can usually see many riflemen on the battlefield, shooting leisurely.

It was a lively fight for a long time, with zero casualties.
