Black Corporation: Joseon - Chapter 664
Episode 664: A little seasoning makes it delicious. (5)
“… So the first idea was to combust the air sucked in from the front of the thruster in this internal combustion chamber and use that power to rotate the wings attached to the back. And the rotational force generated by those wings is sent to the pinwheel for propulsion.”
When Jang Yeong-sil finished her explanation, Hyang could not close her mouth.
‘What is this monster! A turboprop! ‘It’s not really an alien!’
“your majesty?”
Hyang came to her senses after hearing Jang Yeong-sil’s voice calling her and asked Jang Yeong-sil.
“So what are the chances of success?”
In response to Hyang’s curious question, Jang Yeong-sil bowed her head with an embarrassed expression.
“It is my pleasure to inform you, but the possibility of its realization is extremely low.”
“What is the reason?”
Jang Yeong-sil explained why the possibility of realization was extremely low.
-first. Fuel is the problem.
Coal has many limitations in properly utilizing the combustion chamber concept. To solve this problem, I tried using finely chopped coal, but it still did not burn properly.
-second. It is a matter of the material from which the organ is made.
I have used all the steels developed so far, but their durability is very poor in high temperature and high pressure situations.
“… In the case of a multi-wheeled engine using the steam of a steam engine, there is no major problem because it can only withstand the heat of the steam, but the heat of the combustion chamber becomes a problem. “If it can produce proper strength, it will at least be at a temperature that melts iron.”
“Right. So it’s impossible right now?”
“That’s right.”
In response to Jang Yeong-sil’s answer, Hyang nodded silently. But inside, I was sighing with relief.
‘yes! This is normal! Look, we got a proper turboprop engine here! ‘Is that an alien or a human?’
While Hyang was sighing in relief, Jang Yeong-sil became restless. This was because the scent remained silent.
In the end, Jang Yeong-sil came up with ‘Plan (乙)’.
“So, I have a new idea!”
“What is it?”
“It comes down to using a substitute mechanism.”
“Daeshingikijeon? Are you planning to use gunpowder as fuel?”
“That’s right!”
After thinking about Jang Yeong-sil’s answer for a moment, Hyang immediately began pointing out the problem.
“Do you remember why the military retired all new devices except the small ones used to send urgent messages in emergencies?”
“It is due to the explosion of gunpowder used as a propellant.”
“We put a lot of effort into solving that problem, but you probably didn’t forget that we couldn’t solve it properly and had to retire it, right?”
Jang Yeong-sil’s head tilted downward at Hyang’s point.
* * *
The gunpowder rocket symbolized by Singijeon was an extremely unstable object.
Stuck between instantaneous explosion and continuous combustion, many experiments had to be conducted to maintain the latter.
The result of the experiment was to place a body made of paper on top of a pointed iron cone and fill it with gunpowder. Afterwards, when the cone was removed, the cone-shaped space became a combustion chamber.
Although this method enabled minimally stable firing, the risk of explosion was quite high due to the characteristics of gunpowder. In particular, the risk of using large amounts of gunpowder was much higher than that of small guns.
Since the fuel used was gunpowder and a large amount of gunpowder, it took up not only manufacturing costs but also maintenance costs.
Therefore, as the performance of artillery was greatly improved through the virtue of incense, and bigyeokjincheonroe and long guns were developed and distributed in large quantities, the Daesin Machinery and Sanhwasingijeon were retired.
However, just because it was retired did not mean it completely disappeared.
-Development of fuel suitable for the new technology’s propulsion method.
-Development of a method to control the driving force of Singijeon.
The above problems were listed in the challenge log. Of course, the level of difficulty was an imaginary level called Ugong Isan.
* * *
Jang Yeong-sil, who was bowing her head to Hyang’s criticism, carefully proposed an alternative.
“What if instead of making the body out of paper, I made it out of iron?”
“If you were to run that body, would that structure and material be used?”
“I think we could use iron instead of wood.”
“Then the weight will increase, and then the Shingijeon will have to become bigger, right? Then the flying machine will become heavier again, and you haven’t forgotten the saying about a vicious cycle, right?”
“Ah…”
“And isn’t there also a problem with propulsion control, which is one of the problems listed in the challenge record?”
Jang Yeong-sil eventually waved the white flag in response to Hyang’s criticism.
“I apologize. God had such an absurd idea. “I have been so proud that Your Majesty has cared for me all this time.”
At Jang Yeong-sil’s self-reproach, Hyang smiled and comforted him.
“Jim thinks it’s not at all vain. There just isn’t much left to actually do it right now. “If our future generations do not forget to do so, they will be able to turn the thoughts of the Lord into reality.”
“I just hope that happens. Then, I will complete the production according to the drawings given by Your Majesty.”
“I will only believe in the scriptures.”
Hyang, who finished the conversation and was about to go back, suddenly stopped and returned to Jang Yeong-sil.
“I have something to ask Sir. “Perhaps…”
Jang Yeong-sil, who was thinking deeply about Hyang’s subsequent words, immediately nodded.
“I think it’s possible.”
“Then let’s pursue that as well.”
“I follow your orders.”
After finishing her meeting with Jang Yeong-sil, Hyang sighed inwardly.
‘Whoa~. I managed to save something that almost disappeared in the Anyeo incident, but it almost caused an even bigger accident!’
In history before Hyang intervened, Jang Yeong-sil disappeared from history after taking responsibility for the accident in which Anyeo, which King Sejong was riding, was destroyed. The record of birth and death itself completely disappeared, becoming a mysterious entity.
However, with the intervention of Hyang, Jang Yeong-sil became a key figure in Area 51 and a celebrity to the point of being called ‘incomprehensible’.
However, if an accident occurred with the flying machine made according to Jang Yeong-sil’s second plan, it would have resulted in a more serious accident than Anyeo.
Hyang’s accident, which had continued up to that point, suddenly fell into Samcheonpo.
‘What if that guy is really an alien and was targeted?’
If it was the nature of King Sejong or Hyang, it was certain that if there were no casualties, it would end in dismissal. Then, as expected, it would disappear beyond the records of history.
Hyang, who had been thinking that far, smiled and shook her head.
“Aye~. “It went too far.”
“your majesty? “Is there anything you would like to tell me?”
Hyang, who came to his senses and answered the question of the merchant who heard Hyang muttering to himself, shook his head again.
“Oh no. “I was lost in thought for a moment.”

A month later, a room was attached to the unit that operated the monks.
“What kind of room is this?”
“Recruiting applicants?”
Soldiers flocked to the applicant recruitment notice posted out of nowhere to check the details.
-This time, Area 51 created a new object called a flying machine. We need people to handle this.
-The flying machine is an object that flies in the sky like a bhikkhu.
-Applicants are selected from among those who run the bhikkhu.
-We welcome those who have good eyesight, quick movements, good strength, and great courage.
-It is a very experimental piece, so it is very dangerous.
“Aye~. Bhikkhus are also dangerous, but the word ‘very’ isn’t added, right? But ‘very’ is added? “It’s best not to go.”
“cancer! “Your body is your property, but if you become an asshole, it’s only you who loses!”
Even as they said that, the soldiers could not leave their presence.
The first reason was that these were soldiers who handled monks. These were people who knew better than anyone else the charm of floating in the sky.
The second reason was because of the last condition.
-Those who pass the test will be paid twice the salary. If a person dies or becomes disabled due to illness, he or she will be treated as a first-class war meritorious person.
The salary was a salary, but treatment as a ‘meritorious person’ was also a problem. First-class war veterans were treated only by those who had accumulated meritorious deeds by participating in the ‘Defense of Uiju’ and the ‘Battle of Yangyangseong’.
In the end, within two days after the notice was posted, applicants flocked in.

Summer of the 3rd year of the Imperial Calendar (1451).
The rainy season is over and people have gathered again at the waterside during the hottest time of the year.
“What else does Nara have to show you this time?”
“They say it’s a flying machine?”
“Fly? what is that?”
“They say it’s a flying object.”
“Then you are a monk?”
“I heard he’s different from that one?”
“Draw it?”
With people full of curiosity gathering and the shouts of customers selling all kinds of snacks echoing from all directions, professors from Europe were also gathered in one place, their eyes shining.
“‘Flying’… what would you like to call it?”
“Wouldn’t you know it only after seeing the real thing?”
“Everything else is good in the Empire, but when an object is made, only the name in the imperial language is given….”
“Isn’t it an honor to choose a Latin name for that object? By the way, international students are still not coming….”
“From what I heard, very few people passed the first test. “I’m watching Jaesi again.”
The professors all sighed at the rumor told by their fellow professor.
“Whoa~. I sent a letter telling them to select as carefully as possible and take the test…”
“The standard of the empire is too high.”
While the conversation was going on, loud music and people’s cheers for national independence began to erupt.
“Your Majesty the Emperor!”
“hurray!”
“hurray! hurray!”
According to the newly established etiquette, the people did not have to bow down on the floor. Instead, the people showed their respect to the emperor by passionately shouting “Hurrah!”
This may have been an example, but it was proof that loyalty to the scent was strong.
Hyang lightly raised his hand in response to the people’s cheers and soon climbed onto the prepared platform.
As soon as all the royal officials took their seats following the scent, the demonstration began.
* * *
The demonstration of the flying machine that followed gave a great shock to everyone except those involved.
This was because a small boat made of leather without air sacs, like the one on a bhikkhu, and a flying machine with large biplane wings and a pinwheel flew into the sky solely by human power.
“It flies! Fly!”
“It flew! “It flew!”
“Wow!”
Amid the cheers of the people, the flying machine, which rose to about 20 feet (about 60 meters), circled above the head of the village and soon flew toward the downstream of the Han River.
The flying machine flew so far out of sight that it returned again after some time.
The flight of the flying machine ended with a smooth landing through the skillful handling of the pilot. Hyang stood up and clapped vigorously.
“How magnificent! “Great!”
The two soldiers who were in charge of flying the plane under Hyang’s rule bowed down on the ground and shouted.
“Hwang Eun is devastated!”
On that day, the big and small baserunners and baserunners in Seoul made the best sales.
Also, professors from Europe wrote letters like crazy.
“You have to come and see it right now!”
“Flying in the sky!”
* * *
While many people were amazed by the flight of the flying machine, there were others who were not.
It was Wan and the craftsmen he led.
“I’m devastated.”
“What did we do?”
While the emperor and Jang Yeong-sil were preoccupied with the steam engine-powered monk, they created something completely different.
When Wan and the artisans were feeling lost, the scent called them.
