Ming Dynasty: Tanks blocked the door and you said to me, "Long live Ming Dynasty"

The twenty craftsmen were divided into pairs to work together.

Zhou Laosan and Lu Shu were assigned to a group and were responsible for the gun barrels.

I saw them take a gun barrel blank from the rack and carefully put it into the clamp.

Once everything is ready, the fixture is controlled to move towards the tool on the guide rail.

With a "sizzling" sound, the blank and the cutter came into close contact, and steel chips as thin as hair were cut off from the blank by the cutter.

The less you cut each time, the less likely you are to make mistakes. It can also extend the life of the tool, which is the experience they have accumulated over their long-term work.

It has been a year since Zhu Youxiao and Xu Guangqi worked together to develop the machine tool.

During this year, the number of skilled operators has increased.

The old bring the new, the new become old, and the cycle repeats itself.

Coupled with reasonable division of labor and independent processes, we have achieved our current results.

After looking for a while, Zhu Youxiao started walking around the shed with his hands behind his back.

Drilling, boring, planing, milling.......

Ten machine tools were turning at the same time, and the sound of metal processing could be heard throughout the entire shed.

To other people, these sounds would definitely be the loudest noise, but Zhu Youxiao felt they were as beautiful as the sound of nature.

The AK47 has a total of 96 parts, from the barrel and body to the bolt and spring. Zhu Youxiao's requirements are not high. As long as he can make one today, he will be satisfied.

After walking around, he was bored, so he went back to the table, asked someone to bring tools, and started to disassemble the pocket watch on his hand.

In fact, the Ming Dynasty also had clocks at this time, but they were not in the palace, but in the Imperial Observatory.

It is said to have been invented by Su Song and Han Gonglian during the Northern Song Dynasty. It is called the Water-Powered Observatory and has a high accuracy, with an error of only one second per day.

Its internal structure is almost the same as that of later clocks, but that thing is too large and really inconvenient to carry around.

Before, Zhu Youxiao had thought about dismantling the water-powered astronomical observatory and making a clock based on the internal structure, but he was too busy with things on weekdays, so the idea was just a spur-of-the-moment thought and he threw it aside afterwards.

Now that we have the pocket watch donated by Valdes, it can be used to disassemble and copy it.

Chapter 513: Gun

Zhu Youxiao is busy.

Xu Guangqi and Wu Chunfu were also not idle. They were responsible for five machine tools respectively, not providing guidance but doing odd jobs.

Whenever a craftsman needs something, they are required to go out to coordinate and allocate it.

When it was almost ten o'clock, Wei Zhongxian brought a group of eunuchs and brought hot meals.

Seeing Zhu Youxiao still busy at the table, he immediately knelt down.

"Your Majesty, please take a rest. I have brought you some food. Please fill your stomach first."

Zhu Youxiao asked without even looking up: "Why did it arrive just now?"

A trace of panic flashed across Wei Zhongxian's face: "Your Majesty, it's snowing outside again, the road is slippery, and a few of the unruly kids slipped and fell..."

"I can only take them back and have someone make another one..."

Zhu Youxiao looked up outside and saw that snowflakes had started falling again without him noticing.

"Okay, don't blame them."

"Let Master Xu notify everyone to stop and eat together."

Wei Zhongxian then breathed a sigh of relief, got up from the ground, carefully took the food out of the food box, and placed it on the table one by one.

Xu Guangqi stopped all the craftsmen, and the fire bulls also stopped, and the shed suddenly became quiet.

When the craftsmen heard that the emperor was going to invite them to dinner, their bodies began to tremble with excitement.

Working under the emperor's command, you can also eat imperial meals. This is something you can brag about for the rest of your life!

There was limited space around the table, and it was impossible for all the craftsmen to gather around.

But the truth is, they don't have the courage to really come over and eat it.

Wei Zhongxian ordered someone to bring bowls and chopsticks, distributed some food to each craftsman, and let them return to their workstations to eat.

There were a lot of dishes, twenty-eight in total, and six soups.

Fortunately there are so many, otherwise there wouldn’t be enough to share.

Half an hour later, the meal was over and the fire bulldozer and machine tool started running again.

Sun Yuanhua, Xuan Ling Tianyi and others were dragged back to the medical school by Wu Youxing.

In his words, these three guys have some serious problems and need to be taken care of. Otherwise, let alone living to be a hundred, even living to be sixty will be a problem...

The craftsmen started working, and Zhu Youxiao also began to measure the parts in the pocket watch.

Time passed little by little.

Among the AK's 96 parts, some small and simple ones were also processed and sent to Zhu Youxiao's desk.

Xu Guangqi really wanted to know what would happen after these parts were assembled together!

But he could only wait patiently...

While waiting, I used a ruler to check whether the parts made by the craftsmen were qualified.

At four o'clock in the afternoon, the sky was getting dark, the snow stopped, and a bell rang outside, signaling the end of work.

But few of the craftsmen who had finished their work left.

They all gathered outside shed No. 137, and looked through the window at Lu Shu, Zhou Laosan and others who were still busy working inside, their eyes full of envy.

At five o'clock, it was completely dark, but the fire bull was still running.

Zhu Youxiao rubbed his temple. There were not many parts in the pocket watch, but they were too small, making measurement very difficult. At the end of the day, he felt that his brain was about to be hollowed out.

He picked up the ginseng tea and took a sip. He inadvertently saw the craftsmen gathered outside, so he frowned and said to Wei Zhongxian.

"Let them all go back and rest!"

"It's so cold, you're standing outside and you're going to freeze. Are you not going to work tomorrow?"

Wei Zhongxian shrank his neck. He had actually chased them away several times, but these craftsmen refused to leave. He did not want to use force for fear of disturbing his own emperor.

But now with these words, he is not so worried anymore.

After getting outside, he shouted at the top of his voice.

"It's all gone!"

"Whoever stands here like a pole again will not be allowed to come to work!"

After hearing this, the craftsmen, although reluctant, had to leave, looking back every few steps.

At seven o'clock in the evening, the last part was delivered to Zhu Youxiao by Wu Chunfu himself.

"Your Majesty, all are here!"

Ninety-six parts, almost filling the entire table.

Looking at these treasures shining with gray and white light, Zhu Youxiao happily stretched out his hands and assembled them in order.

The sound of crackling continued to come from his hands.

Xu Guangqi and Wu Chunfu stood opposite the table, staring intently with their eyes wide open.

The parts were pieced together in ways they could not have imagined, gradually becoming a whole.

Then, these wholes are assembled into larger individuals.

It took Zhu Youxiao nearly twenty minutes to put these parts together into a complete AK.

"Your Majesty, what is this thing used for?"

It was not until this time that Xu Guangqi asked the question that had been weighing on his mind for the entire day.

To him, the shape of this thing was too strange and he couldn't see its purpose at all.

Zhu Youxiao skillfully opened the safety, pulled the bolt, and pulled the trigger.

"Snapped!"

The crisp sound coming from the gun barrel was very pleasant to the ear.

He smiled at everyone and said, "There is still one thing missing. Once it is made, you will know!"

As he spoke, he pulled out a drawing from the table and handed it over.

This is a drawing of a modern bullet, 8mm caliber and 55mm long.

The whole body is composed of a lead bullet, a copper shell and a primer, and the internal charge is about two grams.

Unlike the complicated drawings of AK47, Xu Guangqi only stared at this bullet drawing for a while and then made a guess.

"Your Majesty, this... seems to be a fixed bullet?"

"But why use copper for the shell? Isn't that a waste?"

"Also, how can the shell be ejected from the barrel? Also, the bottom of the bullet is sealed with a copper sheet, how can the gunpowder inside the bullet be ignited?"

"No need to ask, you will know when it is done."

Zhu Youxiao kept it a secret and did not give him an explanation on the spot.

The manufacture of bullets becomes much easier with the advent of nitrocellulose.

Lead bullets are inherently soft, so although casting is the quickest way to make them, they can also be processed quickly on a machine tool, and a bunch can be made in minutes.

As for the bullet casing, it is also not too difficult. You can use a machine tool to make a mold and then stamp it out directly.

The most difficult part of the entire bullet is the primer.

But even so, it only took one night for the first bullet to be placed in front of Zhu Youxiao.

During that night, the most time-consuming part was spent on the stamping die for the bullet casing.

Seven o'clock the next morning.

The sky was filled with morning glow. Zhu Youxiao, who had not slept for two days and two nights, walked out of the shed carrying an AK47 that had not been painted!

Chapter 514 Cheng Ying

Outside the factory, craftsmen who came to work were walking towards this side in groups of three or five.

When they saw them coming towards them, they all stopped subconsciously.

Although Zhu Youxiao was wearing casual clothes, Wei Zhongxian and Sun Kangwang who surrounded him exposed his identity.

"Look, what is His Majesty holding in his hand?"

"It should be what was made yesterday, right?"

"The gun doesn't look like a gun, and the knife doesn't look like a knife. It's so weird!"

"It's really strange. And, what is your majesty going to do?"

"........."

The craftsmen watched from afar, pointing and guessing what the AK47 was in Zhu Youxiao's hand.

Zhu Youxiao did not let them wonder for too long. After leaving the factory and coming to an open area, he stopped.

After rechecking the AK in his hand, he pulled the trigger at a big tree in the distance.

"Bang bang bang..."

"Bang bang..."

"Bang bang bang..."

There was a continuous burst of gunfire, which suddenly became louder. Yellow bullet casings flew out of the gun barrel and fell to the ground, making a tinkling sound.

Xu Guangqi and Wu Chunfu were petrified upon seeing this.

"Be good!"

"This... this is actually a gun?"
