The mage in the late Qing Dynasty

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

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

Without Benjamin Goldberg, Zhao Chuanxin would never have been 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 pulled the trigger, the firing pin was pushed by a compression spring to accelerate its forward motion. 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 fuze at the bottom. As the slide moves further forward, the firing pin ignites the gunpowder through the bullet and ejects the bullet.

When a bullet is fired, recoil acts on the bolt, pushing the bolt rearward, 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’s easier said than done.

It was when the recoil pushed the bolt that the problem occurred.

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

It was almost like pressing 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 said angrily: 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 the master and apprentice were the only ones 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 master and apprentice 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 hard with his feet.

boom!

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

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

He silently picked up the submachine gun, placed 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 gun again...

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

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

Seeing 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 been a failure.

This was not what he expected.

Master, let's eat first, there's no rush to make a gun.

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.

Grinding his teeth and making a long sound: What's wrong?

I can't find anyone.

What do you mean? The two-legged guy 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 work for me, otherwise he will be his enemy.

Which John Morgan has the heart of a bear but the courage of a leopard? Zhao Chuanxin was furious. Go to Wall Street and do him today.

It was J.P. Morgan who was a master of asset restructuring, proficient in financial business, and presided over the establishment of the monopoly of the United States Steel Company.

So you know who Zhao Chuanxin 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 in his chair.

Miao Cuihua came behind him and massaged his shoulders: Don't be discouraged. In the worst case, we can go back to China and start all over again. The worst is, 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 were no calluses on the palms of my hands.

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

Does it look good? Why don't you go back home and take a look?

Haha, not yet, 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 line of defense has been defeated, and the last hold on is crumbling.

Miao Cuihua saw him walking out with the foreign snot baby and the foreigner named Jesse. She 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 was smart enough not to have thought of 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 great 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 was 10,000 times more active than going to school. He had 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 this kid Benjamin Goldberg telling him to enlighten.

Enlightenment means starting over.

After all, I have the experience of doing it once, and 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.

Why is Zhao Chuanxian called the God of War?

He always fights with one enemy, and the enemy usually suffers heavy casualties, which may be greater than on a battlefield where hundreds or even thousands of people are shooting at each other.

Therefore, the enemy will be afraid of him.

If he had a submachine gun, both he and the insurance team in Lugang Town would change the situation of the war.

And the submachine gun is just the first step.

It was imperative to invent the submachine gun.

Even if it is not currently suitable for large-scale deployment on the battlefield and is only used by Zhao Chuanxin himself, it must be developed.

He put away his impetuosity and discussed it seriously with his apprentice.

Master, I need to use stronger and more reliable materials for the firing pin, otherwise it will always malfunction.

Zhao Chuanxin set his sights on beryllium copper.

Beryllium copper has high strength, hardness and corrosion resistance, making it better than high carbon steel, but of course more expensive.

Zhao Chuanxin gritted his teeth and said: Fake, this time our gun head, jamming plate, roller, hammer, bore, trigger, rate of fire selector, anything that requires frequent friction are all made of beryllium copper.

The cost may not be visible for a few guns, but if the number is large, the cost will rise sharply.

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

This time, six right-hand rifling lines were carved into the inner bore.

The thickness of the gun head, the size of the roller, etc. were all determined after repeated discussions between master and apprentice.

Finally, Zhao Chuanxian began to assemble.

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

I pulled the charging handle above, but it was still a little frizzy.

There are three types of lubricants on the table.

One is a light lubricant for cars and carriages, which can also be used on bolt-action 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. This thing sounds professional, but it is actually made from animal fat and will solidify at low temperatures.

Zhao Chuanxin thought for a moment, then disassembled the gun, dipped his hands in high-temperature lubricant that were not too dirty, and began to smear the parts and wipe them carefully with a coarse cloth.

Lubricating the gun is very particular, because no matter what kind of lubricant at this time, it can't compare with the chemically synthesized lubricant in later generations.

Excessive oil will cause carbon deposits and slow down the burning rate of gunpowder.

Too little oil will not lubricate the gun.

Zhao Chuanxin knew a lot about cleaning gun oil.

After handling it, Zhao Chuanxin reinstalled the parts.

This time he did it very seriously,

Because he was not sure whether he could still maintain the patience to continue research if he failed this time.

Whatever it is, it's always the hardest when you take the first step.

Therefore, he had a sense of ritual, waiting for the final practice.

He put on the Fortitude Armor, pulled on the skull mask, loaded the ammunition, and pulled the cocking handle.

Taking a deep breath, with Benjamin Goldberg watching nervously, Zhao Chuanxin pulled the trigger.

Chug tug tug…

As the flames from the muzzle spewed out, and as the metal frenzy poured out, Zhao Chuanxin's high-hanging heart also let go.

He let out the depression of the day.

Benjamin Goldberg jumped out of his chair with joy.

He originally thought that fantasy could make him happy, but today he realized that the most satisfying feeling is when fantasy becomes reality!

In the villa, Freddie Pavitt was working on documents.

He moved the pen freely, with reasonable handwriting layout and smooth and graceful lines. It was the Spencer style cursive script that was popular in the United States and Britain at this time.

Suddenly, he heard a series of rapid gunshots.

The sound of heavy machine gun fire was steady and low.

The continuous gunshots were rapid and sharp.

Rather, it was like dense and orderly gunshots.

Freddy Pavitt's heart moved and he stood up in disbelief: Impossible, could it be, could it be...

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

At this time, the most famous weapons design expert in the United States, John Browning, clearly said that was simply impossible.

Even experts say this, how can we let Zhao Chuanxian, a layman, and a child with no full hair be created?

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

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