Black Corporation: Joseon - Chapter 388

Episode 388 That, Jang Yeong-sil. (5)

At Hyang’s command, Jang Yeong-sil opened the bag she was carrying and took out two objects the size of her fist.

“This?”

When Hyang saw what Jang Yeong-sil had taken out, she cried out in her heart.

‘Archimedes’ screw?’

Meanwhile, Jang Yeong-sil, who took out the item, began to explain.

“As you can see, this item is a modified version of the drill used to dig wells. “The way a pinwheel-type propeller pushes water or the way a driller digs into the ground is similar, so I thought it would take a little bit of tweaking, so I made it.”

“That’s true, but…”

‘Would that be something that could be done with just a little bit of work?’

Hyang nodded, hiding the doubts creeping up in his mind.

When the scent seemed to understand properly, Jang Yeong-sil waved her wide open hand and continued her explanation.

“As you can see, there is no resistance when you wave your hand in the air, but it takes more force to move it like this in water. Therefore, I thought that the reason the pinwheel-type propellers that had been made so far were failing was because water provides more resistance than air. That’s why I took care of the heavenly person. “Since we are digging into the ground, which is harder than water, we expected that if we use that shape and material, we will not experience problems like those caused by the propellers.”

Hyang kept nodding his head at Jang Yeong-sil’s explanation, but inside he continued to express exclamations.

‘No matter how much you start from zero, you can use your imagination to its full potential, but is it really going to be like this? ‘Is this idea possible?’

Although on the inside he was shocked by this unimaginable situation, on the outside he still maintained a calm expression.

Hyang asked Jang Yeong-sil in a calm voice.

“I think the explanation I heard right now will be really useful. However, when I think about my past experience, there is no such thing as a piece with only advantages. Director Jang, what do you think are the disadvantages of this product?”

‘If this had so many advantages, screw propellers wouldn’t have become the trend, right?’

There was a small error in Hyang’s thoughts.

Even in the 21st century, research on ship propulsion devices similar to those conceived by Jang Yeong-sil was steadily progressing through a small number of inventors.

Jang Yeong-sil immediately answered yes to Hyang’s question.

“I agree with your words. This is the name I gave to this spiral thruster arbitrarily. If you compare this spiral thruster with a pinwheel thruster, the pinwheel thruster takes up less space.”

“In other words, if you’re going to install a spiral thruster, you’re saying that you need more space?”

“That’s right. In my own way, I reduced the gap between the peaks of this spiral and dug deeper grooves, but it still takes up more space front and back than a pinwheel. There will be a change in the center of gravity due to the weight of the thruster, and there will have to be a change in the design. So, God has thought of something…”

Jang Yeong-sil paused for a moment, rummaged through her bag, took out a piece of paper, and spread it out on Hyang’s desk.

“As you can see, a long pipe is connected from the bow to the stern of the ship, and a spiral thruster is installed inside it. This will avoid having to make major changes to the design. In addition, the stability of the ship can be improved by aligning the thruster with the center of gravity.”

Hyang, who was looking at the concept map while listening to Jang Yeong-sil’s explanation, gaped.

‘me! I know this! I’ve seen something similar! ‘This is a water jet!’

After seeing something unexpected again, Hyang couldn’t get over the shock for a while.

“Lowering? “What do you think?”

Hyang, who got over the shock of Jang Yeong-sil’s question, looked at the concept map seriously again.

“How did you come up with this idea?”

“I came to think about blowers used in steel mills and workshops rather than using my own hands.”

“Hmm…”

‘How does consciousness flow to connect them and make something like this pop out?’

Hyang shook her head slightly and looked at the concept map again.

Hyang, who was examining the picture through the paper, shook her head.

“There is a big problem. “This part.”

Hyang continued, pointing to the bow.

“In some ways, sucking up water from the bow is a good idea. However, if the waves hit even the slightest force, the boat will rock violently. If that happens, this bow section won’t be able to absorb water properly, and if that’s the case…”

“Ah! The thrusters may not function properly. “Hmm…”

Jang Yeong-sil, who immediately noticed the problem pointed out by Hyang, glared at the blueprint, took out a gold pen, and changed the blueprint on the spot.

“Wouldn’t it be possible to solve the problem by sucking the water from the bottom of the center of the hull like this?”

“There is another problem. Today’s electric wires are made of wood. Installing institutions of this magnitude requires a complete structural redesign. “It’s not simple.”

“Ah…”

Jang Yeong-sil, who realized the problem with Hyang’s explanation, looked embarrassed. Jang Yeong-sil, who was staring at her work to find the answer, looked at the incense.

“As expected, the only answer is iron wire.”

“In order to properly install and operate the engine that Director Jang envisioned, iron wire would be the best answer.”

“Ah…”

Jang Yeong-sil muttered with a despondent face in response to Hyang’s response.

“The iron wires are still far away… So should we just leave them in there too?”

Hyang shouted at Jang Yeong-sil’s mumbling.

“I don’t know what it is, but take it out right away!”

“yes? These are just ideas, and they may not be possible until the ones posted now are completed…”

“Take them out!”

In response to Hyang’s firm reply, Jang Yeong-sil rummaged through her bag and took out other papers. Jang Yeong-sil opened the first paper and began to explain, pointing at the picture with her finger.

“I found out while actually making and testing the designs sent by the development department that the more wings I added, the better the performance even with a smaller size. So…”

Jang Yeong-sil opened the second piece of paper and continued her explanation.

“I tried combining this multi-wing pinwheel with the conduit propulsion from earlier.”

“Huh~.”

When Hyang saw the second piece of paper, he let out a long breath.

‘It’s a real water jet…’

“Whew~. What other papers are there?”

In response to Hyang’s question, Jang Yeong-sil lifted the paper from the bottom up.

“When we experimented with combining conduits and multiple pinwheels, we found that better performance was achieved when multiple pinwheels were overlapped.”

“If that’s the case, wouldn’t it be a good idea to increase the size of the pinwheel?”

“Of course, that could be one answer, but I think it is better to overlap like this when space is limited. Of course, if there is enough space, it would be better to increase the diameter and overlap…”

“Haa~.”

At Jang Yeong-sil’s explanation, Hyang let out a long sigh, unsure whether it was admiration or lamentation.

‘And now the turbine is popping out? Well, it’s not strange that the moment water jets come out, they go all the way to turbines… but what on earth is this era? Starting with Abama, why are there so many non-standard ones?

Hyang, who shook his head as monsters such as Sejong, Yi Sun-ji, Kim Dam, and Jang Yeong-sil appeared from all directions, soon summed up the situation positively.

‘Well, it’s good for me, right? The situation couldn’t be better than this, right? I have a strong supporter behind me. If you are careful, you don’t have to worry about your budget. There is also a gentleman who will make chin chin if you tell him whatever comes to mind. ‘Is it the best?’

Hyang, whose face brightened, looked at Jang Yeong-sil.

“I will put everything on the challenge list except the spiral thruster. “You know why, right?”

Jang Yeong-sil nodded at Hyang’s words.

“Isn’t it because of a problem with the material? “It’s the same problem as a pinwheel propeller.”

“you’re right. So, the screw propeller will be listed in the response record, and the rest will be listed in the challenge record.”

“yes. I understand. “I am truly humbled by the fact that you value my thoughts, which are humble and have no talent other than tinkering with metal, so much.”

Jang Yeong-sil, who expressed her gratitude in a voice full of moisture, was sincere.

Before being selected by King Taejong and entering the palace, he was nothing more than a government servant. Afterwards, his life, which would have ended with a feeling of gratitude just for being removed from office, came to full bloom when he met King Sejong and Hyang.

“I look forward to Director Jang’s abilities in the future.”

“yep! “I will do my best!”

After sending Jang Yeong-sil away, Hyang looked at the papers and took a long breath.

“Whoa~. “This isn’t progress, it’s almost at warp level…”

Hyang paused for a moment and muttered while looking in the direction Jang Yeong-sil had left.

“Is that guy an alien?”

* * *

When a romantic drama about an alien who crash-landed in Joseon in the 21st century became a hit, some people had wild imaginations.

‘If there were aliens who crash-landed on the Korean Peninsula like that, who would be the most likely person?’

Although various people came up and down, one of those who received the most votes was Jang Yeong-sil.

The reason was that the records of when he was born and when he died were unclear, he had no children, and his whereabouts after being dismissed from office were unknown.

It was just a joke to waste time, but it was a scent that suddenly made me suspicious.

“If it’s not an alien, it’s too much to do, right? “Even if it’s outside the standard.”

It was a scent that he had no idea how he would be evaluated in the future.

* * *

The screw thruster and other proposals submitted by Jang Young-sil were immediately organized into documents and posted on the bulletin board.

“huh? “A response record has been released?”

“Reply? In which field?”

When a new notice was posted on the bulletin board, researchers and artisans flocked again.

In particular, upon hearing the rumor that a plan listed in the response record had been published, researchers and craftsmen read the contents carefully with great curiosity.

“First understanding of the propulsion system?”

Researchers and craftsmen who had been thinking about the pinwheel propeller were so excited that they had found the first answer and were glued to the bulletin board.

“Ah…”

“This way!”

A researcher in the development department burst into laughter after seeing the screw-type propeller presented by Jang Yeong-sil.

“What is this again? “A response and a challenge?”

“huh?”

“Is this also Director Jang?”

Researchers and craftsmen were busy nodding their heads in admiration while reading posts about ‘ducted propellers, multi-wing propellers, multi-wing multi-layer thrusters’.

“ah! This method….”

“I think we’ll find the answer if we carry out the research we’re doing now, right?”

“By the way, how can Director Jang think like this?”

While stories of admiration and jealousy toward Jang Yeong-sil were being exchanged, one person cried out in sorrow.

“ah! “Why did heaven give birth to me and Director Jang?”

“What are you saying?”

In response to the bewildered reactions of the people around him, the person who spoke raised his voice with a puzzled look on his face.

“Just kidding! Just kidding! “You can’t even tell a joke!”

After the commotion passed, executives from the development department spoke to their subordinates.

“ruler! Let’s go back and get to work quickly. How long will you follow Director Jang’s shadow? “Shouldn’t we try to include our names in the challenge record and response record?”

“yes! “I’ll buy it back!”

In this way, the tradition of Jeonjeonrok and Eungjeonrok created by Hyang continued.

Even after hundreds of years had passed, mathematical academies and engineering academies and engineering academies – universities and graduate schools – across the country still had their own records. Faculty and researchers at institutes and academies were required to submit research project development projects at a level that would be included in the challenge record at least once every two years.

Among the challenges that emerged, those judged to be of high value were listed in the national challenge record directly managed by the government and received intensive support.

As this tradition continues, Korea has always been able to stay at least half a step ahead in global technological and scientific competition.

Because of this, the governments of other countries always growled against the Korean government.

“Korea, make the challenge records public!”

“We’re not hiding anything, what are you talking about? “You don’t miss a broadcast every time something new is listed in the national challenge record, right?”

Other countries snorted at the Korean government’s answer.

“joy! Other than that, open the original record! A challenging record created in the era of great leaps!”

“Why do you want to see something from hundreds of years ago? “Don’t you know how much science and technology have advanced since then?”

“joy! Who do you know through pants and jackets? We also have ears to hear! There are still a lot of unresolved issues in the original challenge log! Release it now!”

“The second time. If you’re confident that you’ll be fine, cut open my stomach. Then, how many countries ended up in bloodshed?”

“Ugh!”

Every time the Korean government gave an answer, other countries’ governments had to grind their teeth. And the Korean government launched a large-scale internal investigation.

“What kind of stupid person is making such a fuss?”

‘Won Jeon Do-rok’, created during the Great Leap Forward, was treated at the same level as the ‘Holy Grail’ or ‘Holy Ark’.

The early members who worked in the research center created by Hyang and Area 51 used their imagination to the fullest to solve situations that amounted to bare ground. As Hyang’s MSG was added to the imagination of those people, the original challenge record revealed enormous challenges – even Hyang. It was listed as either science fiction or magic.

In the end, it was natural that a huge espionage war and criminal attempt took place over this original copy.

Amidst this invisible bloody struggle, the original record included the following words:

‘The original Jeonjeonrok is stained with the blood vomited by researchers and craftsmen and the blood of Milwi who died to protect the Jeonjeonrok.’
