Black Corporation: Joseon - Chapter 57
Episode 57: New Weapons (5)
A decision was made to dig a large steel wire inside the Jang Chong Tong, but the craftsmen were faced with another problem.
“Which direction should I turn?”
After thinking about the direction of rotation of the steel wire, Hyang came to a conclusion.
“Wouldn’t it be okay to make one in the direction opposite to the direction of rotation of the clock hand when viewed from the muzzle of the gun?”
At those words, Haesan Choi opened the tablet and started calculating.
“There are 4 types of rotations, from half a turn to 2 rounds, and 2 types of rotation direction, so we need to check for deviations, so at least 5… That makes 40. It will take some time.”
“You have to try.”
At Hyang’s words, the craftsmen present let out a small sigh. But no one complained. The work was difficult, but firing the barrel was surprisingly refreshing, and checking the results was fun in its own way.
Of course, Choi Hae-san and Lee Cheon, who were caught in the middle, were more trouble than fun.
In subsequent tests, all 40 guns showed performance that exceeded expectations. Even if more than 5 shots were fired from all 40 guns, there was no problem and there was no significant decrease in power.
However, in the process of analyzing the test results, an unexpected result emerged: the accuracy rate was higher than expected. In response to the unexpected results, Haesan Choi submitted a report and made a suggestion.
“Until then, it was said that if you fired 20 shots at a distance of 70 steps, you would be lucky if you got 5 shots. But in this test, all 40 arrows hit all targets at a distance of 70 steps. We need research on this!”
“I see. Let’s do it! Get ready.”
“Yes, sir!”
Hyang clenched his fists as he watched Choi Hae-san’s back excitedly leaving.
‘Oh yea! Asked! ‘
Choi Haesan and Icheon craftsmen fired hundreds of bullets to find the cause of the unexpected result and a way to exploit it.
Through that process, military officers and craftsmen learned several facts.
-The rotation speed of the groove cut inside the barrel was 1 and a half revolutions to achieve the best performance.
-When tied to the fixture as tightly as possible and fired, the bullet hit a target up to 500 steps (approximately 600m) away. However, this literally hits the target board and is not a spectator (an arrow hitting the center of the target).
-However, this does not mean that the distance fired from the barrel has increased. Regardless of whether there is a rifling or not, 2 dongs (approximately 7.5g) of powder-type gunpowder can fire 5 dongs (approximately 17g) of bullets up to 800 paces (approximately 960m).
-If hit from a distance of 500 paces, the bullet did not penetrate the steel plate used as a target. However, looking at the crooked state of the iron sword, it is assumed that it can cause serious injury to the enemy.
-The direction of rotating the groove must be consistent with the direction in which the barrel body and stopper are tightened. If you do the opposite, the more you fire, the more the gun barrel and stopper will loosen.
“Why not try an experiment by increasing the amount of gunpowder?”
Choi Haesan and Lee Cheon showed enthusiasm, but Hyang shook his head.
“It is likely that we will repeat the problems of the previous president.”
“Ah…”
“Rather than that, let’s systematize the results we have obtained.”
“Yes sir.”
Hyang and Choi Haesan Icheon classified the survey results as follows.
-Maximum range: Literally, the farthest distance traveled when fired with specified gunpowder and bullets. The bullet has almost no power.
-Maximum effective range: The distance at which a hit of at least 30% or more can be expected when aiming and shooting. However, it must maintain the power to inflict a certain level of injury to the target.
-Effective range: The maximum distance at which trained Fuhrer soldiers can hit the target when aiming and shooting.
According to the classification made by Hyang, Choi Haesan, and Icheon, the performance of the rotary grooved chuntong was a maximum range of 800 steps, a maximum effective range of 350 steps, and an effective range of 250 steps.
While Hyang and Choi Haesan and Icheon were classifying the results and expressing great satisfaction, the institute’s officials and craftsmen were struggling to solve the homework given by Hyang.
“‘Analyze the reason why President Zhang’s performance suddenly improved.’ La….” “If
you look at the test results so far, the only reason why performance improved so dramatically was by rotating the groove. But why did this result come out? Did you come….”
“Yes. That’s the problem….”
The most likely suspect was the ‘rotating groove’, but the officials and craftsmen could not easily figure out what the groove had done.
While the officials and craftsmen were pondering, the military commander’s poet (a craftsman who made arrows for the dead) expressed his opinion.
“Isn’t that groove what makes the bullet spin?”
“It makes the bullet spin? Tell me more.”
The poet explained in more detail, even using hand gestures.
“When they attach the feather to an arrow, they attach it slightly out of alignment. Then, the arrow leaves the arrow and flies in a circle like this. What happens then is that the arrow flies straight. It is less prone to side winds. ”
“Really?”
The officials and craftsmen thought it was plausible and began testing various sizes of bullets. As a result, it was confirmed that the bullet engaging the protruding part of the rotating groove rotates, resulting in an improvement in accuracy.
The knowledge discovered in this way and the data obtained during the testing process were all written down in documents and carefully stored in a safe located in the deepest part of the same class.
“This is a top secret connected to our country’s national defense, so everyone must pay attention to confidentiality.”
The officials and artisans responded with one voice to the warning of the village.
“I will keep this in mind!”
* * *
This confidentiality was maintained despite the audit taking place. While Choi Hae-san explained to King Sejong the process of creating the President, he did not reveal the part about this rotating groove until the end.
King Sejong When I learned about this part, it was after the audit was over. Choi Hae-san, who met King Sejong alone, submitted a written report, and King Sejong, who read the document, nodded.
“The reason why the crown prince and the officials kept it secret until the end was I understand. In that case, Gwaine should follow suit. Bring the merchant ship’s brazier.”
King Sejong threw the read report into the brazier and burned it.
Meanwhile, while Choi Haesan was reporting to King Sejong in writing, Hyang muttered as he looked at the related records.
“If rumors of President Jang’s performance become known, they will definitely be leaked. This will be it. During the battle, they were captured, stolen, or sold for bribes. And we’ll have fun replicating it. However, when they understand the principles and try to improve, our Joseon Dynasty will be one step ahead. That’s why we’re rolling it out like this.”
* * *
“I’ll say it again, you’ve made a truly excellent weapon.”
“The Fuhrers that the Fuhrer soldiers will use are planning to unify with this Kapsikjang Fuhrer.”
Hwang Hee heard Choi Hae-san’s words . As she was about to say something, King Sejong raised his hand to cover Hwang Hee’s mouth.
“Hmm… I think it will be okay if we deploy sequentially starting from the northern region right away. good night! Let’s review that plan.”
“Seongseong is devastated! ”
“I am devastated! “
When King Sejong came to a positive conclusion regarding the production and deployment of Gap-sikjang Chongtong, Hyang, Choi Haesan, and Icheon and other officials gathered in unison and shouted, ‘Our success is ruined!’”
“Yes. Has the President decided on this?”
“No. There is another type of President. The Horseback President.”
“Hoo?”
When Sejong showed interest, Choi Haesan made a gesture. At Choi Hae-san’s gesture, a military officer wearing blue armor came in.
“The color of the armor is…”
“This is the new armor we developed together. I will explain later.”
“Is that so? Then let’s proceed.”
Choi Haesan continued speaking in response to King Sejong’s command.
“What I’m going to show you this time is a Gap-type horse-mounted rifle.”
As soon as Choi Haesan finished speaking, the military officer opened the lid of the long leather pouch worn on his right waist, took out a silver gun barrel, folded his arms, and held it with the muzzle pointing upward.
“I want to take a closer look.”
“Yes, Your Highness.”
In response to King Sejong’s order, the military attache placed the gun on both hands and held it out politely. King Sejong, who was looking around at the barrel handed to him by the military officer, stopped at the round iron barrel hanging in the center of the barrel.
“Six holes? Is this rifle really capable of firing six bullets?”
“I’ll fire back.”
“Huh!”
King Sejong, greatly surprised, looked back.
Looking at Sejong’s surprised eyes, Hyang smiled and answered.
“This is one of Area 51’s masterpieces.”
‘Of course, the design was original’, but
what was in the hands of the military officer was the ‘Colt 1860 Arm’ whose caliber was modified to suit the situation of the Joseon military. This was a product that was being prepared as a successor to the Kentucky Rifle when Hyang lived in the 21st century.
In response to Hyang’s response, King Sejong returned the gun to the military officer and
said, “I want to see how he shoots it.”
“yes.”
In the demonstration that followed, the military attaché hit all six shots on a target board installed 30 paces (approximately 36m) away. The target board that the craftsmen retrieved had six holes neatly drilled in it. The craftsmen turned the target board back. Dujeong Behind this studded red cloth, iron bullets were meticulously stuck.
King Sejong and the ministers carefully checked the target board. Jo Mal-saeng, who was checking the target board, told King Sejong his impressions.
“The Jurchen people who came within at least 30 paces I think the pirates will see hell.”
“Do you think so? ”
“yes! ”
In response to Jo Mal-saeng’s assertion, King Sejong looked at Choi Hae-san and Lee Cheon. Their faces, both of whom had strong military backgrounds, were full of confidence. After checking their faces, King Sejong nodded.
“Looking at the expressions on their faces, I understand. Then, regarding the armor,
“I apologize, Your Majesty. I still have some firearms left to introduce you to.”
“Still?”
Sejong looked slightly tired. The efforts put in by the crown prince and those under him were visible to the presidents I just saw.
If gunpowder and the commanders could be properly supplied, securing the safety of Joseon was as easy as flipping the palm of your hand.
‘No. If you put in a little more effort, you can restore the reality of the old Samhan, as Brother Yangnyeong said! ‘
As I was trying to suppress my burgeoning greed, Choi Haesan was lighting the spark again.
Sejong, who was about to leave, sat down again after hearing Choi Hae-san’s words.
“General! Proceed!”
“I am devastated. The weapon to be introduced this time is a fire bomb. We must move the location.”
“…Please guide me.”
“Yes, Your Highness.”
Sejong walked while being guided by Choi Haesan.
“It’s quite a distance, isn’t it?”
Sejong, who was slightly out of breath, explained the reason.
“Because the place is the place…”
“Should I have ridden a horse?”
“Abama. It has been said that a man’s two legs are like the pillars of a house. When the pillars are strong, the house becomes strong…”
The scent is healthy. When he was about to make a long speech about this, King Sejong hurriedly interrupted him.
“… Walk, don’t walk.”
“Must have strong legs to prevent bloating…”
“He walks! That kid talks a lot! He gets bloated no matter what he does… How did you happen to give birth to a child like this…” The
mouth continued. Sejong was grumbling, but he put in more effort and took long strides.
* * *
The place where Choi Hae-san and Lee Cheon guided King Sejong was a larger place than the previous demonstration hall. Not only was it large, but it had taller and thicker earthen walls.
In front of the podium where King Sejong and his ministers were seated, the wall made of sacks of soil was taller and thicker than before. On the opposite side was the beginning of the foothills of Mt. Mokmyeok, and there was bare land at least 50 square meters wide.
“Did they cut down the trees? ”
“Yes, because a fire could break out.”
“That’s right….”
As King Sejong and the ministers took their places on the podium, the craftsmen and soldiers who were waiting placed a large table and soon brought various items to the table. It was placed on the
table. Choi Hae-san, who was sitting next to the statue, began introducing the new weapon.
“The fire bombs I will show you from now on are fire bombs fired with a toy.”
Choi Hae-san pointed to a round fire bomb made of cast iron with his baton.
“We named this fire bomb Bigyeokjincheonroe (飛擊震天雷).”
“Bigyeokjincheonroe… Is it a type of Jincheonroe? ”
“What is Jincheonlei? ”
“I’ve only seen it in records, but it’s said to be similar to Jilseopotong. It is recorded that it was used by Song and Geum.”
“Is it because they use toys that they have a special reputation? ”
In response to Choi Haesan’s explanation, the ministers reminisced and exchanged opinions. Looking at the reactions of the ministers, Hyang smiled wryly.
‘If you talk about King Munjong, you may be surprised at the news, but you can’t miss a cliché! A cliché among clichés! A turtle ship in the sea and a bigyeokjincheonroe on land!’
