Jin Cheon-hee replied, "I have no choice but to give the same answer as Master. I will make sure you don't die easily."
Jin Cheon-hee habitually loosened his hands.
Behind him, only his father's beast-like roar echoed.
The hospital was not beautiful.
The hospital was not peaceful.
It was just fighting and fighting.
"Hahaha, I... I have become a surgeon in the martial world."
Jin Cheon-hee laughed as if he had lost his mind.
Outside, preparations for the operating room were in full swing.
They washed the entire operating room with strong alcohol and boiled water.
It was cumbersome, but there was no choice.
There was a small knife for dissection here, though not as good as a scalpel, it seemed usable in a pinch.
He had to do it without the help of basic medical equipment from Earth, like the common suction found in any hospital.
And that felt like a big problem.
Still, he had to do it.
Even in such poor conditions, it wasn't impossible to win.
"Shall I replace the scalpel with sword energy? Hahaha... At least our patient has vital signs, that's something..."
Jin Cheon-hee muttered helplessly for a reason.
The patient had a liver laceration, commonly known as a liver rupture.
The renowned Naegigong method had crushed the liver like tofu, causing a colon perforation.
A perforation means a hole in an internal organ, and if left alone, death is inevitable.
Because food will leak out of the intestines, causing peritonitis, and blood will pool in the peritoneum, causing hemoperitoneum.
Due to the nature of the Naegigong method, the ribs were intact.
It was a truly strange thing.
In fact, this patient should have died long ago.
Surviving for 15 days in this state was a bizarre thing for a doctor like Jin Cheon-hee to see.
'How is he still alive? Is it because of that inner strength and miraculous medicine? But inner strength and miraculous medicine can't heal a torn liver, can they?' Jin Cheon-hee sighed and washed his face with his hands.
Then he thought about the laws that govern this world.
Qi.
'Qi is truly omnipotent, omnipotent.
It seems to act as an antibiotic and also sustains life.
In reality, it should be a state of low blood pressure due to internal bleeding, but it somehow prevents ventricular tachycardia.
Wow...
If qigong treatment existed in modern medicine, it could save cancer patients.
Amazing.
Truly amazing.'
In this world, martial artists run on water and ignite fire with their fingers.
Their skin becomes as hard as steel.
Finally, when they reach the pinnacle of swordsmanship, aging stops, and they become young for a moment.
Here, they call it rejuvenation.
'I have to keep in mind the true qi during the surgery, but there are more than a few other things needed.
There's too much lacking.'
First, securing blood.
In a place without blood type kits, he used a primitive method.
He collected a little blood from the father and daughter to observe their antibody reactions.
Fortunately, they were compatible without antibody reactions.
'Transfusion between relatives is rarely done in modern medicine...'
Because of Graft versus Host Disease (GVHD).
It means the parent's white blood cells survive in the child's body and start dividing on their own.
And those divided white blood cells begin to attack the child's body, recognizing it as an enemy.
So, it's only used in unavoidable cases.
For example, when the person needing a transfusion has a rare blood type.
It's only used in such unavoidable situations.
In that case, a process to kill lymphocytes in advance is necessary.
'But radiation treatment is impossible in this era.
Usually, the probability of it going that far is low.'
Jin Cheon-hee fell into thought.
'But if I don't transfuse, the child will die 100%.'
There was no choice.
When he said he needed blood, Gung-gwi told him to take as much as needed to the point of death.
He didn't ask why it was needed or where it would be used.
Normally, one would shout, "It's sorcery!" but he just asked to save his daughter.
So Jin Cheon-hee had to devise a means to draw his blood and supply it to his daughter on the spot.
'What kind of person is Yoo-ho really?'
Yoo-ho's mysterious ability.
When he asked him to make an infusion line for transfusion, trusting in that ability, he made it in less than half a shichen.
That was actually more amazing, but it wasn't the time to worry about that.
The patient was in front of him.
Using that, he connected Gung-gwi's body to his daughter's body.
Blood flowed directly from Gung-gwi's body to his daughter's body.
This was also extremely primitive, but now was not the time to nitpick.
Jin Cheon-hee quietly took a deep breath.
'Incision is half the battle.'
Surgery starts with securing visibility and ends with securing visibility.
If visibility could be secured, half the battle was won.
'With the patient turned to the side, perform a posterolateral thoracotomy.'
Raise the arm and fix it, then cut along the scapula.
'If I cut through the intercostal space, I can secure visibility.'
But the problem was what to cut with.
To cut cleanly without modern instruments...
'Since I'm in the martial world, can I cut with sword energy and then reattach it? Maybe this could be much cleaner and have a better prognosis than modern medicine.'
Jin Cheon-hee wanted to use everything he could since he was in the martial world.
'A living sword is not just a living sword for nothing.'
Smiling for a moment, Jin Cheon-hee's expression darkened again.
'Once I open the body, there's no turning back.'
Master said that the moment the blade touches the flesh, the inner strength maintaining the body would drop sharply.
Right now, it's barely holding on with miraculous medicine, inner strength, and the father's true qi, but once the chest is opened, the vital signs will drop significantly.
During that time, it was Jegal-lin's job to somehow buy time using the formation.
But since it was unknown how long he could hold out, it was important to resolve it within that time.
Jin Cheon-hee closed his eyes and slowly moved his fingers.
In his mind, the liver and spleen, arteries and veins drawn by Master naturally appeared.
He missed the CT from Earth.
The time when he used to turn it around and look before surgery...
'Radiology...
I miss it.'
Like Master Jegal-lin, someday Jin Cheon-hee would also be able to unfold human radiology.
Even so, he was still a chick.
Even if the Five Elements Mind Method activated his brain, that fact did not change.
Complaining for a moment, Jin Cheon-hee began to train his image by constantly recalling the patient's insides.
He had to be fast.
And he had to be accurate.
And he had some confidence in that part.
In the past, he had been recognized for his abilities in surgery.
The experiences he gained from volunteering in remote areas also improved Jin Cheon-hee's surgical skills.
And now he had learned martial arts.
His five senses had risen to a state incomparable to the past.
'I can do it.'
Jin Cheon-hee's eyes sparkled.
Finally, all preparations were complete.
Jin Cheon-hee wrapped himself tightly from head to toe with cloth so that not a single hair was exposed.
Master, Yoo-ho, and all the medical staff also wore the same clothes.
They looked like masked men in white clothes, which made Jin Cheon-hee chuckle softly.
"Hee-ya."
"Yes, Master."
"I've been watching you for a while, and when you're under pressure, you deliberately laugh."
Hearing that, he felt as if his inner thoughts had been exposed, and he flinched.
Jin Cheon-hee spoke.
"But our attire is somehow funny."
An old senior once said, the only thing a patient has is the doctor.
If the doctor looks like they're about to die, the patient truly has nowhere to trust.
It was a senior who eventually left, unable to endure the politics of a university hospital.
But that saying remained with Jin Cheon-hee.
He said a little shamelessness was just right. 'That doctor is a bit annoying,' but still, 'He seems confident, so he must be good,' and trust him.
Yoo-ho spoke.
"It's because we're in a hurry now. Next time, I'll make it properly."
"I'm looking forward to it."
Jin Cheon-hee lightly stretched.
Master spoke.
"The operating room has been set up to be maintained by the formation. The entrance is affected by the fire technique, so cover yourself with water qi."
Master entered inside.
A small blue flame swept over Master's body.
It was surprising, but more than that, he thought, 'An automatic sterilizer is convenient.' The old days of struggling to put on gloves flashed by like a revolving lantern.
Jin Cheon-hee covered himself with water qi.
Then he followed Master inside.
The fire qi swept over his body.
The operating room was not the kind of place Jin Cheon-hee knew.
On the floor, formations using the formation method were drawn, and the surgical gowns worn by the medical staff were from the martial world.
However, the patient lying down was just like on Earth, so Jin Cheon-hee smiled bitterly.
'They said I laugh forcibly when I feel pressure.'
Now it had become a habit, and there was nothing he could do about it.
"The surgical plan you devised has already been conveyed to the medical staff. I made them memorize it, but in the end, you have to do it."
There was anxiety in the eyes of the medical staff.
Small stature, small body.
A child.
But they didn't utter any common complaints or words mixed with concern.
It meant that Master Jegal-lin's organizational control was excellent.
Jin Cheon-hee replied, "Well, it's not a difficult thing..."
The chief surgeon leading the surgery also needed to be a bit shameless.
Jin Cheon-hee continued, "Let's finish it quickly and eat something delicious."
Saying that, he picked up the small knife for surgery.
"Thoracotomy."
A red line was drawn above the patient's solar plexus.
There was no turning back now.
'It's a treatment method that involves cutting the body.
Until this treatment called surgery is over, you must keep breathing, but the medical staff here are not skilled enough to do that.
So you are needed.
Are you prepared to endure anything to save your daughter?' At Baekrin's words, Gung-gwi answered that he would do anything.
And now Gung-gwi was here.
In the operating room.
In this bizarre place he had never seen before, Gung-gwi steadied his trembling body and tightly grasped his daughter's wrist.
To connect his daughter's life, he was infusing his true origin qi.
Transfusing blood while simultaneously infusing true origin qi was not an ordinary task, but he was doing it with extreme concentration.
The power of qi is tremendous.
It can even temporarily keep a dying person alive.
Baekrin's medical staff also learned the Five Elements True Qi for that reason, as Baekrin explained to Gung-gwi.
To use acupuncture most effectively, inner qi was necessary, and the Five Elements True Qi was one of the fundamental methods that allowed doctors to treat patients more effectively.
It was also the reason Baekrin's medical staff was among the top three medical organizations in the world.
