Doctor’s Rebirth

Chapter 47

“It seems you have a lot to ask.”

In response to Jin Cheon-hee’s words, Sama Byeong replied.

“We should learn what we can learn.”

It was an impressive thirst for knowledge.

Jin Cheon-hee answered everyone’s questions with a faint smile.

They all had fire in their eyes, eager to learn even a little of Jin Cheon-hee’s techniques.

This was what all physicians wished for.

It was even more so because gaining recognition for medical skills in the Medical Pavilion was not an easy task.

But Jin Cheon-hee himself felt differently.

Upon returning to his quarters, Jin Cheon-hee sighed as he changed his clothes.

“Haa…”

He scratched his head vigorously and then plopped down on the floor.

“As expected… I’m still lacking a lot. Especially a suction device and antibiotics are needed. Without clear visibility, surgery is impossible. Since martial artists who can use the Void Absorption Technique technique are rare, it can’t be used for many patients, right? And without antibiotics after surgery…”

Yoo Ho had done his best.

It was at a level beyond what could be hoped for.

But he wasn’t omnipotent. Items that are commonplace in any modern hospital were not available here.

It was frustrating that he couldn’t even deliver half of half of his skills.

He was anxious beyond measure. The biggest reason was separate.

‘The master’s condition isn’t good either. If I don’t prepare in advance, it’s dangerous. I can’t predict what variables might occur during surgery. A person’s life isn’t a game, and once the abdomen is opened, it’s too late.’

Thinking that far made his throat dry.

That’s why Jin Cheon-hee didn’t notice someone entering the room very quietly.

“These are words I’ve never heard before in my life. So, you still feel lacking?”

“Oh! Master?”

“I didn’t want to disturb you as you were deep in thought, but I couldn’t help being curious.”

Fortunately, he hadn’t voiced his worries about the master out loud.

“I was thinking about some points to improve after today’s surgery.”

“The four great hall masters were making a fuss as if it were a festival, but you look like you’ve seen it all.”

“Hahaha.”

“You’re laughing again. Don’t push yourself too hard.”

Zhuge Rin stroked Jin Cheon-hee’s head.

Jin Cheon-hee closed his eyes. The large, cold hand felt good.

It resembled a snake’s body temperature.

Jin Cheon-hee felt like he could do anything if he could make this hand warm.

‘Because the master’s life is at stake.’

In truth, if it were just about treating patients, Jin Cheon-hee might have been able to rejoice today.

What greater satisfaction could there be for a doctor than being able to save patients who otherwise couldn’t be saved with his knowledge?

But Jin Cheon-hee saw the limitations before the satisfaction.

‘It’s not enough. This alone is far from enough.’

Then it was something to overcome.

If nothing is done, the master will die.

“I want to create something new, Master.”

“There’s no need to be impatient, I said.”

“Because I have to treat you, Master! At this rate, at this rate, there will be a limit.”

Jin Cheon-hee’s lips formed a straight line.

Zhuge Rin finally burst into laughter at his disciple’s expression.

“How cute. To think that such a small disciple will be the one to treat my body.”

He laughed for a while, seemingly greatly amused, and then said,

“Then what can I do for you?”

“I think I’ll need to borrow Yoo Ho for a long time.”

“Hmm?”

“Because I need to make penicillin.”

Penicillin.

Humanity’s first antibiotic. Jin Cheon-hee decided to throw him into cultivation hell.

‘Let’s make a cultivation room, a cultivation room.’

The surgery at the Cloud Dragon Escort Agency. Wang Gak-yeon’s surgery. And the appendix surgery just now.

He could realize more clearly while performing these surgeries.

Although qi energy is certainly a remarkable power, and elixirs are indeed miraculous medicines of fantasy, they still absolutely could not replace advanced medical equipment including antibiotics.

Even if he couldn’t make advanced medical equipment, he at least had to make antibiotics.

The reason was simple.

Antibiotics can be mass-produced, and their effects are absolute.

So Jin Cheon-hee intended to make Yoo Ho the martial world’s first nurse and the fairy of the cultivation room.

‘Wow, our Yoo Ho, getting two jobs! I’m jealous. Hey! A nurse and a pharmaceutical researcher and producer! Just great!’

Not knowing the amount of work Yoo Ho would face, the master asked,

“Penicillin? Alright. I’ll arrange for him to come to the Medical Pavilion whenever you order. But will that be enough?”

Jin Cheon-hee nodded.

“Of course, Master! Yoo Ho is such an outstanding person. I’m grateful for his help.”

“I’m somewhat envious. He can receive a lot of living knowledge by your side. If only my body were better, I could do the same.”

Not knowing the truth, the master was simply envious of Yoo Ho.

“No, Master. Your priority should be preserving your health. You saw the appendix surgery, right? Surgery is an extremely dangerous treatment method. If any unexpected situation occurs during your surgery, even I wouldn’t be able to do anything.”

“So there’s a time limit even during surgery.”

Jin Cheon-hee smiled bitterly.

‘The time bomb during surgery is a problem, but everyday life is also an issue. It’s more like a landmine. We don’t know if it will explode in a year or today.’

He could only hope that the master’s internal energy would hold out.

Jin Cheon-hee said,

“Please stay healthy until then, Master.”

“Alright. I promise, my little doctor.”

Neither of them asked for Yoo Ho’s opinion.

The martial world’s first, fairy of the cultivation room!

It was truly a beautiful name.

And so, Yoo Ho once again gained a new job.

For the person in question, it was a cause for tears of blood.

***

Jin Cheon-hee’s daily routine became extremely busy.

He had to spread knowledge about surgical procedures to the Medical Pavilion physicians and give lectures on the book written with Yoo Ho’s help.

He also conducted dissection practices on corpses and managed to squeeze in martial arts training. And the most important thing.

He began the development of penicillin.

Penicillin is a beta-lactam antibiotic extracted from blue mold.

This much information can be found with a quick search in an encyclopedia.

But few people know that mold is sensitive to temperature, light, and humidity, and even if all these conditions are met, cultivation might fail if just one thing is off.

‘Why isn’t it growing? What’s the problem? The professor did it in one go, what’s your problem?’

Biology is different from mathematics. No matter how much I devote myself to the culture dish, if it doesn’t grow, it doesn’t grow.

It’s truly the heart of a house mushroom farmer.

Especially, blue mold is sensitive to air, and extraction and purification are hell.

Even if hundreds of flasks are used, the amount collected is only enough penicillin for one person to use.

Moreover, it’s difficult to administer orally, and due to its short half-life, its effectiveness is low.

The method Jin Cheon-hee was using was the submerged culture method using a large fermentation tank, that is, the Deep tank method discovered during World War II.

“I’ve prepared as you said, but is this really correct?”

Yoo Ho had prepared ceramic tanks necessary for penicillin production as per Jin Cheon-hee’s request.

“Oh, this is not bad.”

Although made of ceramic instead of metal, it wasn’t bad at all.

“So the Medical Pavilion members are hugging the fermentation tank at the bottom?”

“Yes. We need to continuously inject air at the bottom and stir using the Wind Qi of the Five-Elemental Cultivation Technique.”

Thus, the martial world’s first cultivation fairy (or slave) was created. On Earth, this would have been done by a machine motor, but Jin Cheon-hee decided to use people.

‘Sigh, isn’t this all to save lives? Also, the master said that recently the Medical Pavilion members have been neglecting their internal energy training, which has become a problem.’

Moreover, the qi of this world helps in the growth of all things. So he had hopes that it might be better for the blue mold as well.

Yoo Ho said with sunken eyes,

“Although I haven’t learned the Five-Elemental Cultivation Technique, I can handle wind energy. The master said that since you’ve already set it up, I should do the initial cultivation as well.”

Just what is that guy’s true identity? Jin Cheon-hee pondered this again today as he smiled brightly.

“Yes, because blue mold is sensitive. With Chief Yoo, I can rest assured.”

“Once fermentation is complete, a Medical Pavilion member who has mastered the ice condensation of the Five-Elemental Cultivation Technique will rapidly cool the fermented liquid for purification, right?”

3-5 degrees Celsius would be good. The acidic water to be used at this time should be about pH 2.

But since there’s no way to measure this accurately, they decided to strictly quantify the amount of internal energy to be used and the method of producing purified water.

After removing impurities this way, it will be made into pill form and stored in the coolest place in the medicine hall.

This is the plan so far.

‘But there are too many variables.’

Aside from maintaining consistent quality of penicillin, he couldn’t be sure if things from this world would have the same effect on people as on Earth.

He had to start with experiments using mice, step by step.

Jin Cheon-hee said,

“This is all for the master.”

“Hahaha, every time I think about the workload, my murderous intent towards you, young master, surges.”

He’s juggling studies as a nurse, work as a cultivation slave, training juniors, and various miscellaneous tasks.

‘Maintaining oxygen in the cultivation tank will be crucial.’

The nutrient to be used during the growth phase of the bacteria is lactose.

They plan to use cow’s and sheep’s milk.

Later, when they reach the full-scale production stage, he intends to try things like rapeseed oil.

‘Antibiotics are absolutely necessary for the master’s surgery.’

Originally, he would have forgotten the method of penicillin production itself. But thanks to the Profound Origin Heaven and Earth Divine Technique, even things he had briefly studied in passing started to come back clearly to his memory.

“And here are the items you requested.”

Yoo Ho additionally brought out the surgical tools Jin Cheon-hee had requested.

Jin Cheon-hee paid the most attention to the syringe needles among them.

After examining them for a while, he asked,

“Can’t the needles be made any thinner?”

“What? Even thinner than this? If you want them thinner, it would be faster to request from the blacksmiths of the Tang family, known as the ancestral home of hidden weapons.”

Jin Cheon-hee let out a sigh.

“Then please request from those blacksmiths even if we have to.”

“Is this also for saving the master’s life?”

“Yes.”

“Haa, I can’t handle you, young master. Alright. I’ll try to procure them.”

“Thank you.”

Jin Cheon-hee expressed his gratitude honestly.

“I’ll die from overwork before I get to kill you, young master. Really.”

At those words, Jin Cheon-hee grinned.

“You’re not going to tell me how you can do so many tasks at once, right?”

“Yes, it’s a secret, young master.”

Yoo Ho grumbled as he diligently noted down the additional items Jin Cheon-hee requested.

The Medical Pavilion members watched this scene with great curiosity.
