Black Corporation: Joseon - Chapter 175

Episode 175 Feedback (4)

Since it was King Sejong’s order, Hyang worked diligently to find a solution.

The first person Hyang visited was Icheon, who was in charge of managing Area 51.

“Are you talking about the signal fire?”

“yes. A signal fire uses fire and smoke, but can’t it be used in rainy weather?”

“That’s right.”

“How do you notify me in that case?”

Hearing Hyang’s words, Lee Cheon stroked his beard and traced related memories.

“Hmm… According to what I remember, I heard that instead of a signal fire, a white or red flag is raised on a high pole.”

“Is that so? thank you.”

“What.”

Hyang returned to his office, tapping his fingers on the desk and muttering.

“This is such a pain in the ass. If you have a telegraph, you can use Morse code. This…”

Hyang suddenly stopped talking. Hyang opened his eyes as wide as possible and reflected on his words.

“Morse code? sign? code?”

Crash!

Hyang suddenly stood up and ran to the wall where the maps were hung.

“The location of the Jin and Gwan barracks…”

“The location of each local government office…”

Hyang’s face brightened as he muttered as he traced various places on the map with his finger.

“found!”

Five days later, Hyang visited Geunjeongjeon with a bright face.

“So what happened today? “It seems like a good thing to see your face bright.”

Hyang responded to Sejong’s words with a big smile.

“Yes, Abama.”

“okay? “What is the good thing that made our Crown Prince smile?”

“I have solved the communication problem you asked me to solve a few days ago.”

Sejong was pleased with Hyang’s answer.

“okay?”

“That’s right. “Hang it in the inner coffin.”

“Yes sir.”

The eunuch who followed the order of the head hung the royal painting on a hanging hanging on one side of Geunjeongjeon.

Hyang, standing next to the map, began explaining to King Sejong and the ministers.

“The dots marked in red on this map are the barracks and swimming pools installed throughout Joseon. And the blue dot is the Jinguan installed through this installation. And the green dots are stations across the country.”

“I see.”

King Sejong and the ministers nodded at Hyang’s explanation, but their faces said, ‘So what?’ It was full of questions.

Looking at those expressions, Hyang continued to explain while turning over the map. The second map had red and blue lines drawn horizontally and vertically.

“As you can see from this map, if we connect the barracks, Suyeong Jin-gwan, and the station, we can connect the entire Joseon Dynasty.”

“That’s right. What you’re saying is that we should connect and communicate like that, but aren’t we already doing that? The problem is that the speed is slow, so beacons are used as an improvement measure, but it is difficult to know in detail what happened using beacons alone.”

Hyang nodded at Sejong’s point.

“you’re right. Soja pointed out that very point. “What we want to provide through this network is that fast communication is possible.”

Hyang handed over the paper of the chart and showed the third map to King Sejong and the ministers. The third map had two-digit numbers written on the barracks and swimming pools in each province.

“We designate the capital, Hanseong, as 0, and assign two digits to the barracks and swimming pools in each province. Then, a two-digit number is assigned to the officer on the command line. Also, two-digit numbers are assigned to towns near Jingwan. “This way, you can tell which region you are in using just six numbers.”

“Hoo?”

Sejong, whose face had been full of doubt until then, adjusted his posture with a twinkle in his eye.

“I see. If it’s a 6-digit number like that, you’ll know right away where it is. so? Surely you don’t mean to convey that by signal? “If we do that, the number of beacons will immediately become too large.”

“you’re right. “If we were to convey not only the region but also the content, the number of furnaces at the beacon fire station would be limited to the current five.”

“yes.”

“So Soja proposes to build a watchtower along the station I mentioned earlier.”

“Building a watchtower?”

“Yes, we will build watchtowers at intervals of 5 ri (2 km) and transmit information through semaphore signals.”

“Hand signals?”

Sejong tilted his head at Hyang’s words, and Jo Mal-saeng made an ambiguous expression.

“I definitely heard that the navy sends signals with flags.”

“Similar but different.”

In response to Jo Mal-saeng’s remarks, Hyang turned over the paper.

The fourth piece of paper contained four-digit number combinations for various situations.

“Starting with 1111, which indicates that there is no problem, the combination of numbers allows us to know not only the invasion of Japanese enemies but also its scale, and even the outbreak of natural disasters and plagues.”

“It’s okay. It’s okay, but… it’s a 10-digit number in total. Do you mean to convey this using the watchtower? how?”

The ministers all nodded at Sejong’s point. Hyang answered Sejong’s question with a confident face.

“Two flags are enough.”

“Two flags?”

“We have prepared a demonstration in the front yard of Geunjeongjeon.”

“okay? “Let’s all go out.”

“Yes, Your Highness.”

At Hyang’s words, King Sejong came down from the house and walked with great strides. The ministers also followed Sejong’s footsteps.

* * *

When King Sejong and his ministers, filled with curiosity, appeared in the front yard of Geunjeongjeon, the waiting soldiers and military officers all saluted.

“Military courtesy!”

“insect!”

“Thank you for your hard work.”

When the military officers and soldiers straightened their postures in response to King Sejong’s response, King Sejong looked back.

“okay. “I want to see how you do it.”

“yes. “Let’s proceed with the demonstration!”

“ancient! Forward to the signalman!”

At the military officer’s order, four soldiers stepped forward holding flags in both hands. The military officer gave an order as the soldiers lined up with each hand holding a flag painted half diagonally in red and yellow.

“preparation!”

At the command of the military officer, the soldiers stretched out both hands holding the flag.

“one! two! three! “Four!….”

Every time a military officer gave an order, the soldiers expressed the number by moving the flags in both hands around.

Sejong nodded after confirming that the 10 numbers from 1 to 0 were expressed as flags.

“Surely, in this way, all numbers can be expressed with two flags. Hmm… let’s organize things a bit. Sir, what you were thinking was to build watchtowers at intervals of 5 ri and deploy soldiers trained like that to communicate?”

“you’re right. We communicate on a regular basis for every city, and when there is urgent news, such as an invasion by Japanese enemies, we hang a red flag on the top of the watchtower to announce the emergency, and send hand signals to spread the message. In addition, just in case, we place one horse at each watchtower.”

Sejong repeatedly nodded at the explanation of the fragrance.

“It’s okay. are you okay.”

As Sejong received favorable reviews, Lee Jik, who was standing behind him, pointed out a problem.

“But the size of the chi is small. Considering the distance of 5 ri, wouldn’t it be difficult to confirm?”

In response to Lee Jik’s criticism, Jo Mal-saeng stepped forward on Hyang’s behalf.

“No, it’s entirely possible. “If it’s a large monoscope used by the navy on board a warship, it can go up to 10 miles.”

“Is that so?”

“exactly.”

Jo Mal-saeng, who responded to Lee Jik, spoke to King Sejong.

“majesty! The crown prince insisted on 5 ri, but considering the deployment and operation of soldiers, the gap is too narrow. “I believe that the large monoscope used by the navy would be able to detect it even from a distance of 10 ri.”

“Hmm… 10 liras…”

Hearing Jo Mal-saeng’s words, King Sejong stroked his beard and was lost in thought.

‘Of course, training soldiers and maintaining facilities all cost money. It’s good to spend as little money as possible, but there’s no way this bastard wouldn’t have thought about it…’

Sejong thought for a moment and came to a conclusion.

“The military team will take the monoscopes used by the Land Guard Army and the Giseon Army and test which one is more useful. Also, please test and report what distance between watchtowers is most appropriate.”

“I follow your orders!”

Jo Mal-saeng excitedly responded to King Sejong’s command. Thanks to the incense, jobs increased, but for the military, it was because a very good high-speed means of communication was created.

Returning to Geunjeongjeon and entering the temple, King Sejong looked back at the ministers.

“I gave the order to the soldiers, but I want to hear the officers’ judgment.”

Heo Jo was the first to answer King Sejong’s question.

“I am reporting this to Lord Heojo, the new Judge of the Joseon Dynasty. I think the method suggested by the crown prince is a truly useful method. Even excluding wars, the quicker we respond to epidemics and disasters, the less damage we can do. “If we use the plan proposed by the crown prince, we will be able to respond quickly and incomparably with today.”

“is it? “Any other opinions?”

In response to King Sejong’s question, Yeonguijeong Lee Jik stepped forward.

“I believe that the plan proposed by the crown prince is the optimal means.”

The situation ended with the Yeonguijeong, the head of the ministers, coming forward and agreeing. No, it was almost over.

Dae Heon, who had been quietly listening to the conversation, stepped forward.

“majesty. I have one question to ask the crown prince. Please grant it.”

“Daesaheon? Huh~. It’s been a while since I heard Dae Heon’s remarks. “I guess it’s okay.”

“I am devastated.”

After receiving permission, Daesaheon looked at the incense and asked.

“I have something I would like to ask the crown prince.”

“Yes, I will listen.”

At Daesaheon’s words, Hyang became very nervous and straightened his posture. No matter what anyone says, the representative figures of ‘Kkojangkkojang’ were Daesaheon and Daesagan.

After hearing Hyang’s answer, Daeheon slowly opened his mouth.

“God does not know much about war and does not know much about weapons. However, I understand the usefulness of what the Crown Prince said today.”

‘what? A sudden compliment?’

King Sejong and the ministers, as well as Hyang, who were involved in Daesaheon’s praise, all looked at Daesaheon in surprise.

Again, the representative of ‘Kkojang Kkojang’ was Dae Heon. Usually, if there was even the slightest problem, Daeheon was the one who would stick to it until the end.

That’s why Hyang looked at Dae Heon with an even more nervous expression. Daeheon Daeheon continued speaking, whether he knew how that scent felt or not.

“I’ll say it again, I don’t know much about props. That is why I have a question for you. That flag signal is useful, but you have to see it with the human eye to check it. What should I do if there is fog, rain, or it is nighttime and I cannot see the flag with my eyes?”

“ah!”

Everyone in Geunjeongjeon gave a look of disappointment at Daesaheon’s point. Sejong looked at Hyang with eyes full of worry.

‘Son!’

‘It’s within the expected range!’

At Daesaheon’s question, Hyang internally breathed a sigh of relief. After taking a moment to catch his breath, Hyang answered Dae Heon’s question.

“As the Great Saheon asked, flag signals are definitely unreasonable in situations such as cloudy weather or rainy weather at night.”

“Then do you have an alternative?”

“We are currently researching it. “The reason we didn’t bring it out now is because it was a problem that would have to be decided first on how to build a watchtower.”

“Is that so? “You mean there is an alternative?”

“That’s right.”

In response to Hyang’s response, Daesaheon opened his mouth and addressed King Sejong.

“God’s curiosity has been answered, so there are no more questions.”

“Then do you agree with Crown Prince Gyeongdo’s proposal?”

“Yes, Your Highness.”

After hearing Daesaheon’s answer, King Sejong looked at the ministers.

“Now I will come to a clear conclusion. “The military team will conduct an experiment according to the command I mentioned earlier, and the officers of other departments will build communication watchtowers across the country in accordance with the results that the military team will present.”

“I follow your orders!”

After hearing the ministers’ answers, King Sejong looked back.

“The Crown Prince did a good job too. “I look forward to seeing even better results in the future.”

Hyang bowed deeply at Sejong’s request.

“I follow your orders!”

Hyang, who returned to the East Palace, muttered as he relaxed his stiff neck from tension.

“Mr. Samcheonpo, that gentleman is right. It is very correct to say that people in the past were not stupid, but only looked stupid because of the limited amount of information available.”
