Chapter 738
“Ohhh, what is this?”
Jin Cheon-hee faced this question and delivered what he had promised.
“Ah, you’re unfamiliar with it. This is serum. What appears red at the bottom are blood cells.”
There were platelets and white blood cells in the middle, but I simply glossed over that part.
I was just too embarrassed to explain it properly and wanted to die.
“Can blood truly be separated like that?”
“Your Majesty. All things in this world are mostly impure and mixed together. This apparatus is designed to separate them.”
To their eyes, it appeared to be sorcery.
But it was not sorcery.
Because I could see the Royal Sorcerer shaking his head.
The separated blood in the glass beaker was presented to the King. He gazed at it before opening his mouth.
“I see. Yes. Then what is your reason for showing me this?”
“Because this is precisely what resolves the plague.”
I spoke to the King and his ministers in a concise yet easily understandable manner.
The immune system.
And the method of creating the immune system.
A very rough explanation of the method and principles of the immune serum technique.
Since I had to omit the fundamentals, I ended up using somewhat mystical expressions, but it was easier for them to understand that way.
I had to prevent them from dragging people away and burning them as kindling due to lack of comprehension.
“Such a method….”
“Indeed… it is said that those who have contracted smallpox once do not fall ill again. Is it the principle that once the plague spirit enters, the body remembers and repels it?”
“Is it proof that our ancestors’ spirits watch over us?”
The ministers murmured in astonishment.
I realized they had understood in a somewhat peculiar way, but it was familiar to me. The Central Plains were the same.
Rather than saying germs swarm on our hands so we must wash them away, the explanation that soap removes malevolent energy and we must purify ourselves upon entering the house to prevent the plague spirit from coming works far better.
‘It’s like the process of how humans perceive and understand the unknown.’
Just as humans see thunder and think of divine wrath.
My words carried immense ripple effects.
“Be silent.”
At the King’s words, the ministers fell quiet.
“This is a most precious secret and hidden knowledge. Indeed…. They say you are a madman obsessed with saving lives. It seems that rumor is true.”
‘No. How did rumors about me even spread?’
I muttered inwardly while observing the King.
“Moreover, you have already resolved the plague in an entire city….”
‘So they’ve already finished investigating. Well, this is also a kingdom. They must have intelligence organizations.’
Yet they still intended to use human sacrifice. Because it was the ‘tradition’ by which this nation overcame calamities.
I could only hope that would change today.
The King continued.
“Your intention to resolve the plague has already accomplished more than half the task.”
“….”
He admitted it with his own mouth. I focused in silence.
“If I do not repay the debt owed to Jin Taesu, the great benefactor of this nation, then the people will mock their king, and foreign powers will mock our realm. Heheheh. What does the Empire desire?”
First, he bestowed favor, and only then did he request a transaction.
An ordinary person might have simply wiped their mouth clean after receiving goods, but this was international diplomacy.
If one lost ground on principle and word spread of such pettiness, the consequences could become severe.
And the counterpart happened to be the Hua Empire.
The Hua Empire, as the superior power, could even wage war on the grounds of wounded pride.
For the Damjin Kingdom, temporarily weakened by the plague, an invasion from the Hua Empire would be an enormous burden!
Of course, war did not arise easily, but this was not a democratic world—in the international diplomacy operated by autocrats and kings, such variables remained ever-present threats.
Thus the aging king could not help but feel astonishment at the dazzlingly beautiful young man before him.
And at the same time, a sense of threat as well.
‘I cannot fathom his true intentions at all.’
That he differed from the envoys the Hua Empire had sent before meant his hidden agenda was equally extraordinary.
Meanwhile, I wiped my chest in relief.
“Simply to end the plague and establish trade.”
My counterpart smiled calmly.
“Good. It shall be done as you wish.”
Trade agreement concluded!
‘Hehehehe, restrain yourself. My inner Black Flame Dragon! I’ve prevented human sacrifice—that’s enough.’
I never expected such a simple skill from Earth would cause such amazement here.
I wiped my flushed face.
I felt slightly like dying.
Meanwhile, Seon Geon was somewhat surprised.
‘Hmm, yes. I heard he went through great trouble to create that mechanical device, and it certainly proved worthwhile.’
It looked quite impressive.
* * *
Since I had come as plenipotentiary ambassador, I had to handle the practical affairs myself.
There was not a single person from a literary or scholarly background in this delegation.
‘Krkrkr, this is ruined. Completely ruined.’
Ever since I took hold of power at Baekrin Uisaek, such trivial administrative tasks naturally fell to my subordinates.
After so long, I felt the misery of practical work in a world without Excel.
‘The only person worth using is the military officer in charge of supplies at the army base—a scholar by training—but since he belongs to the military, it’s only right that he attends to military duties.’
No matter how much I’d become a provincial governor, it felt wrong to drag someone away from their own work and demand they do mine instead.
If I took them away like this, how would the generals even survive?
It seemed they had an allergy to abacuses anyway.
‘There’s no helping it. This old me will just have to roll up my sleeves.’
My body was spry and youthful, yet I was being needlessly dramatic.
First, I had the guards bring the equipment I’d brought and installed it on the wasteland beside the capital.
Then word arrived.
“What? They came on their own?”
“Yes. They requested permission from the kingdom and came up with the royal army. Oh, I believed Soggakju had authorized it.”
“What do you mean!”
These stubborn calves really don’t listen to orders.
The physicians from Baekrin Uisaek, whom I’d left in the pastoral city, had come up on their own initiative.
Fortunately, this time they came with support from the royal army, so they traveled comfortably without encountering any bandits along the way.
“Ahhh! Soggakju! We missed you so much!”
“No, you people. You should have just stayed quiet there.”
“It’s obvious you’d do something reckless on your own again. Ugh, seriously!”
“Even if you told us to leave, we wouldn’t. Not until this is all over.”
I asked in return.
“Isn’t it embarrassing to part so solemnly and then meet again like this?”
At my words, all the physicians blushed with shame.
Life is simply like that.
The grander the farewell, the more awkward the reunion becomes.
Especially in cases like this.
I thought to myself.
‘Seeing how much I’ve struggled since then, these people have been concerned about me.’
One person had died.
A child I had taught directly. Foolishly kind, and foolishly sentimental.
“Don’t worry, Soggakju. We’re selfish people, so we absolutely won’t die.”
“That’s right. If things get dangerous, we’ll be the first to run away, so don’t be concerned.”
“If we were truly selfish, we wouldn’t have come this far. You fool!”
The physicians spoke while rubbing their burning cheeks.
“We brought many cattle from the pastoral city. All of them have been vaccinated and have antibodies.”
“The royal army is impressive. Even our elite units couldn’t match their speed of movement through the wasteland.”
The chicks began chirping away, each with their own comments.
I let out a small sigh.
‘At least they came when diplomatic relations had stabilized.’
If the persuasion had failed and the king had tried to perform human sacrifice, I would have had to do something.
If that happened, I couldn’t guarantee the safety of these chicks.
‘Wretched calves! They really don’t listen worth a damn.’
Only then did I understand my Master’s feelings by 0.001%.
It was remarkable progress.
I spoke.
“Since it’s come to this, now I need to produce serum using these fools and bring shamans with royal cooperation.”
Specifically, shamans who handle cold energy.
Since the Minor Ice Essence was precious, I had the ice shamans create a magical portable ice storage using their sorcery.
Of course, since this was also something that hadn’t existed before, I had to create it by mobilizing knowledge of formation arrays and mechanical engineering.
‘Do I really have to create new equipment myself! You bastards!’
An intricate tracheal feeding tube wouldn’t work—it’s too complicated for this era.
To achieve that here, I’d need at least the Sichuan Tang Family or the Namgung Family’s field construction techniques.
I have to keep it simple and practical.
What I’m trying to create is a portable ice storage unit.
The goal is to travel throughout the kingdom delivering serum.
‘If I’m going to carry it and run, it might as well be easy to manage.’
This was an invention born from my heart demon.
Humans are curious creatures—only when faced with genuine malice do they discover kindness they never knew they possessed.
We call that hope, but how many people have died because of that very hope?
I burned through the tobacco, watching it smolder away.
The chicks never left my side.
Even as they cursed and grumbled, they remained steadfast beside me.
Yeo Ha-ryun observed this from the shadows from time to time.
‘A peculiar master-disciple relationship.’
It was something you could never see in the Demonic Cult.
Thus began the preparation work to implement the immune serum method we’d used in the livestock city across the entire nation.
Time passed.
I observed the signs of rain at the border once more.
‘Will it not fall as heavily this time?’
I could feel the moisture in the air.
I tapped out the pipe I’d been holding.
‘It’s nearly complete.’
Now it’s just a matter of sending the serum throughout the kingdom, but that’s work the Damjin Kingdom itself must do, not me.
Still, I decided to remain in the Damjin Kingdom for approximately two more months.
As the one who brought the immune serum method, I needed to confirm that the plague had truly ended.
‘I should gather plenty of materials while I’m here.’
New papers await me.
Of course, the King of Damjin wanted this as well.
In truth, the plague was already as good as resolved.
With the equipment to produce this immune serum and the portable ice storage, even if the plague resurged, prevention and treatment would be possible.
Yet as the person responsible, I remained here.
It was natural that the escort troops and the King had established their camps outside the capital and were staying there.
For that reason.
“Get some rest! Patriarch.”
“You’ll die living like that, sir.”
The ones who used to struggle and groan at my every word now treat the Patriarch like a child set loose by the water’s edge.
Unable to resist their pressure, I came outside.
‘I raised them, but somehow they’ve all grown far too strong.’
Good ones, bad ones, strong ones, gentle ones, arrogant ones.
In the end, I took a walk through the capital, with the now-smaller Hwang-gu and Noeji accompanying me.
“They’ve built this place quite well.”
I gazed around the royal capital, marveling at what I saw.
Things I hadn’t noticed while buried in work were finally beginning to catch my eye.
“I should meet with Ha-ryun. Hwang-gu, do you know where our second is?”
Woof!
As Hwang-gu took the lead, I followed behind.
