Artery.

It is the vein that supplies oxygen to various organs in our body. It means it comes right from the heart.

Therefore, the blood pressure is very high and if the risk is unbelievably high when it is improperly touched.

Ganghyuk is going to cut the vein and reconnect it.

On the table made of wood.

Without any kind of modern equipment.

‘It is a nonsense.’

He thought.

It is not an operation that can be described as a difficult and hard operation.

‘Dangerous. Too dangerous.’

Ganghyuk was hesitant to touch it seeing the vessel bouncing.

The others who have already learned the structure through practices were frozen.

“Can we cut it?”

Yeoni asked with worries.

As a matter of fact, it was not the first time for Ganghyuk to treat it.

But in those cases, he tied the broken parts.

He did not cut the artery.

Anyway, he knows and experiences the artery spurting blood.

“If not?”

Ganghyuk set aside the swollen vessel.

He could see a white structure pressed under it.

“There are nerves.”

Dolseok, Ganghyuk’s best student, said.

He might not know which nerve it was.

But it was encouraging that he could distinguish nerves from other structures.

“Yes, they are nerves.”

Ganghyuk nodded his head being proud of his teaching method.

Then he pointed the nerves.

“They are responsible for the senses of the face. As they are pressed, he got strange stimuli. He felt pains as he was cut.”

“Therefore, he grinned.”

“It gave him enormous pain. Normal people would not stand it.”

If he did not have a strong will and nerves than general people, he would become an invalid long time ago.

The keen pain from time to time makes other issues.

It brings fear for the extreme pain.

People with panic disorder cannot live a normal life because they are afraid when the panic comes to them again. It makes them retreat from the normal life.

This pain plays the same role.

Fear for the pain ruins the patient frequently.

“Then, we should do something on this artery which presses the nerves anyway.”

“Yes, we have to do it, although it is dangerous. It is worth the risk. We have come halfway as we found the cause.”

It was really a fortune.

When he first took the scalpel, he was suspicious if he was right.

It was the first moment in his life.

Using a scalpel without confidence.

‘It is good to find the cause.’

But it was a misfortune that the cause was the artery.

It is the structure to avoid rather than to deal with.

But now he had to cut it.

He was not a killer, so he had to persuade himself.

‘I have to think of Dolseok’s remark.’

Ganghyuk looked at Dolseok who was following Kim Simin every day.

He practiced archery following Simin and his fingers had blisters and bruised.

After some time calluses had formed on his fingers and he was not wounded any more.

However, at the first time, Ganghyuk had to take care of Dolseok’s wounds every day.

It was not clear, who was the servant and who was the master.

Anyway, he could hear from Dolseok about the skills of Simin.

He was a really great archer.

‘Yes, he was a great archer.’

As a matter of fact, Ganghyuk did not have to borrow Dolseok’s remark to know his archery skill. He could see sparrows on the ground with his eyes. All the sparrows were killed by an arrow with the right-side strike.

‘But he makes mistakes when the seizure comes because of this illness. It can be the cause of his death in Jinju War.’

Keen pain can disperse concentration.

Then the possibility to be shot is going up.

‘Given the circumstance, this operation is not only for the pain…’

It can be said that this operation is related with life with some exaggeration.’

In other words, Ganghyuk may save his life.

The great general who led Jinju war to the victory.

Then he should not hesitate.

‘It may bring an earlier end to Imjinwaeran [War between Joseon and Japan].’

There was no possibility to prevent the war given the situation of the government.

They were fighting each other, and they did not pay attention to Japan at all.

Toyotomi Hideyoshi was looking for the cause to invade Joseon at that moment.

But the noble people in Joseon had a cultural superiority complex.

They thought Ming is the center of the world and Joseon, the subject country of Ming, is naturally superior to Japan.

The notion did not have any objective grounds. It was merely from their sense of superiority based on illusion. It was clear that the war would happen.

‘But I cannot make any active role to prevent it.’

If you are a Korean, you may once think of going back to Joseon and save the country.

If I were in Joseon, I would resolve all the issues including Imjinwaeran.

I would make Joseon the strongest country in the world and unify the world.

Ganghyuk was no exception and he had those thought once but he found out that it could not be realized.

‘If I had not been a noble man, I would have already died.’

As caste system was strong, an individual could not do many things.

Even a modern man with intelligence could do little.

Ganghyuk saw how they tortured the people opposite to them in Euigeumbu.

If he tried to work with a party and rushed into the factional strife, he might be killed.

‘I have to keep my position and do what I can do.’

Even though they were not big things themselves, they might bring big changes.

Such as curing Sunshin’s leg, treat Ryu Seongryong, Gwanghae and Simin.

“Ok, we must finish it as soon as possible. Give me a thread.”

“Yes.”

“No, not that one. I need thicker one.”

“This?”

“Yes, that is right. When you cut the artery, you must use the thickest thread. If not, it would burst.”

“Yes, sir.”

Ganghyuk smiled at Yeoni who answered with confidence.

It was good to look at his students who grew every day.

‘They may play big roles in the war.’

They are already good medical professionals.

Especially in trauma.

Moreover, they are excellent in sword fighting.

“Sit, here you are.”

“Yes.”

Ganghyuk came back to the reality from illusion.

He saw the facial artery which became as large as a coin.

“Eum… tie here.”

“Why tying it? We will cut it anyway.”

“If we cut without pretreatment, it will bring a disaster, as it is expanded like this. Although Makbong made his breath lower, it is still too dangerous.”

When the breath decreases, the air in the chest will decrease.

Decreased air means decreased pressure in the chest.

Consequently, it reduces blood pressure.

‘But the effect is very small. That is the trap.’

It can reduce at most 10 to 20.

It means the blood column can be lowered from the height of ceiling to the height of shoulders.

In both cases he will die.

Therefore, they need to reduce the section of the vessel to be cut.

To do this, they need to tie it first.

“Ok, if we tie here and here… We can cut here. It is better to cut here rather than the swollen part, tight?”

“Yes, sir. If we make like this, it can be similar to cutting the normal artery.”

“Yes, we may leave it without sewing if it is impossible to connect.”

“Is that Ok?”

“It should not be, but Simin can survive, I believe.”

Ganghyuk looked at Simin’s face with arms folded.

He could see the scar which was made more than a year ago.

‘He could not have right blood circulation with this broken blood vessel system.’

Imagine it.

If a part is expanded, then the blood will circulate in the expanded part.

The blood may not go to the direction that it should go.

However, the structures behind the artery looked good.

‘Then the opposite side artery is more developed.’

It is not only true for Kim Simin, but also for everyone.

Human bodies are being operated under the same principle.

If a side is destroyed, the other side will help.

Therefore, even if he cut the facial artery in this side, there will not be a big problem.

‘But… to do that, it is injured too much. There are few vessels here.’

The injured part may decay without correct treatment.

He may not die thanks to antibiotics, but it will make a big problem.

It is better to do the right thing from the first place, if possible.

“But in principle we should connect them.”

“Yes, sir.”

“Therefore, your roles are very important. When I give you a signal, you must act promptly.”

“Yes…”

“Ah, then…”

He looked at Dongpa who was standing there at a loss.

He could not do anything but standing and looking at the operation.

It was not because he did not have knowledge or skills.

He lost the rock-paper-scissors game yesterday with Makbong and Dolseok.

Taking a rest is not a bad thing but there was a reason why he was at a loss.

“You should roll up the sleeves so that we can see your arm. Yeoju, prepare the syringe.”

“Yes, euk.”

“You received Makbong’s blood before. Now it’s your turn. You have to give some to others.”

“Yes, sir.”

“It is unclear if we need blood but it is better to be prepared.”

Ganghyuk turned his head from Dongpa who was preparing to be a blood bag.

As there was Yeoju who was an expert in blood collection, he did not need to worry at all.

“Ok, Scissors.”

“Yes”

“Makbong, are you controlling the breath?”

“Yes, I am doing well.”

“Yes, good.”

Ganghyuk knew that Makbong did a good job.

‘The blood color is good. If oxygen lacks, it will not have this color. Heartbeat is about 100 per minute. Although it gives overload, I think he can stand it.’

He was a very strong man.

He could survive if Ganghyuk did not take too much time.

“Now, I am cutting the vessel. When I give you a signal, block it with your hands first.”

“Yes, yes.”

Ganghyuk cut the part which was distant from the heart.

As it is not the direction of blood flowing from the heart, the blood flash was not so much as expected.

If flew like a stream.

The amount was not frightening.

“Block it.”

“Yes, sir!”

Yeoni kept her hands on the section of the artery.

She did not press it as Ganghyuk gave her instruction in advance.

She simply blocked the section.

The blood could be blocked with the blocking only.

“Good. Now, it is the important turn. Yeoju, find the vessel of Dongpa.”

“Yes, sir.”

“Have you done it yet?”

“Yes, I wanted to be prepared.”

“Ok, it is good to be ready.”

Yeoju seemed to have sadistic characteristic.

She injected the iron needle in advance.

Ganghyuk moved the scissors thinking that he must find a B type blood bag, too.

-Cut

It was little different from the last one as it was near the heart.

Although they tried their best to lower the blood pressure, blood splashed.

It might splash to the shoulder of Yeoni who was standing at the opposite side.

“Dolseok”

“Yes”

“Yeoju, draw blood as much as possible. Blood is splashing a lot.”

“Yes, yes.”

“Now, we connect it. He will become a great man, although you don’t know it yet.”
