Doctor’s Rebirth

Chapter 23

“It’s Western Continent style. It will cost a lot since we need to use special workers, but we’ll manage somehow. Or I could make it myself.”

‘Himself? A glass window?’

Jin Cheon-hee looked at Yoo Ho with questioning eyes. The blueprint Jin Cheon-hee had drawn required a huge plate glass wall on one side of the house.

The rectangular plate glass would dramatically increase the amount of natural light.

‘This guy is really suspicious. No, never mind. Isn’t vitamin D more important than that anyway?’

What Jin Cheon-hee had devised was a triple-pane glass window. He completely removed the opening and closing function.

It’s more like a glass wall than a window. Of course, curtains are designed for convenience.

And he drew a separate window for ventilation. This is also made of glass.

It feels like he’s put some effort into architectural design at this point.

Yoo Ho rubbed his chin with his finger and said:

“I was planning to give you a good scolding if it was useless talk, but this is beyond my imagination. And it certainly seems like it would be effective. It’s worth trying whether it works or not.”

He honestly admitted his misjudgment.

It meant he was starting to trust Jin Cheon-hee. Jin Cheon-hee felt a little happy.

“It goes without saying, but… the sooner the better, right?”

“Considering Master’s condition, of course.”

“Good. Let’s have the stove and glass windows made within a day. For the ondol, we’ll need to call in a separate craftsman and redo it from the construction stage.”

He rubbed his chin, lost in thought. Finally, he added:

“It will take additional work to move Master’s quarters elsewhere… but it shouldn’t take more than ten days.”

‘Great! This will greatly alleviate Master’s condition.’

Ondol. It’s one of those things that a hardcore fan of martial arts novels, especially so-called fusion martial arts novels, might search for on the internet at least once.

There’s a reason why protagonists start by making ondol when they cross over to another world.

‘Kudos to myself for watching that documentary to the end!’

Even if you can somehow design it, you need an expert to build it. Suddenly, Jin Cheon-hee realized something odd about Yoo Ho’s words.

“Wait a minute, you’re going to make the stove and glass windows in one day?”

“Yes, is there a problem?”

Yoo Ho looked at Jin Cheon-hee as if asking why he was questioning something so obvious.

‘Come to think of it, this guy was also learning some martial arts. If he says it’s possible, it must be possible. But how?’

Unable to contain his curiosity, he finally asked.

“How?”

“Hahaha, do you think you’re the only one with secrets, young master?”

“Ugh.”

He hit the nail on the head. Yoo Ho said:

“My secret might not be much compared to yours. Well, still. Since you got me good this time…”

“You’re going to tell me?”

“No. I’m petty, you see. I need to keep you curious somehow.”

He smiled mischievously.

At first, I thought he was scary and inscrutable, but he has this side too, Jin Cheon-hee thought. Yoo Ho said:

“If it goes well, I’ll install one in your room too. This is your achievement, after all.”

His voice, pretending to be indifferent, contained quite a deep sense of gratitude.

***

A day later.

When he got up early in the morning and came out, Yoo Ho was removing the existing wooden windows and installing glass ones.

‘He really made them. How did he make these so quickly? It hasn’t even been 10 hours, right? And it’s not like he has modern tools or equipment.’

A deep question appeared on Jin Cheon-hee’s face. But he decided to let it go for now.

Isn’t the important thing that glass windows have been installed!

Moreover, right next to it, a new house is being built.

Seeing that they’re laying the ondol first, it showed incredibly fast execution.

‘Calling in craftsmen and getting them to work right away in just a day. Isn’t that extremely fast?’

It was a bit different from what’s on Earth, but glass was glass.

Moreover, it was a triple-pane window, making it much more airtight than wood.

“The house looks much brighter now that it’s installed, young master.”

“Yes. A lot of sunlight will come in.”

Previously, windows had to be opened to get sunlight.

Now that wasn’t necessary.

‘Actually, I thought the glass windows would be harder to make than the ondol, but he did it so quickly.’

It’s not like glass is common in this world either.

Even Cloud-Dragon Escort Agency used wooden windows with paper. In human history, glass windows didn’t become widespread until much later.

‘Well, many things are different from the actual Earth.’

Jin Cheon-hee scratched his head.

Yoo Ho said:

“Ah, the stove installation is also complete. Master is inside.”

“Really?”

Jin Cheon-hee hurried inside.

Inside, he felt a warm heat. Jin Cheon-hee’s master, Zhuge Rin, was sitting on a long chair, leisurely reading a book.

Warm sunlight poured in from the fairly large glass window, shining down on the master.

It was a dazzling sight, worthy of a movie scene.

‘It’s so warm just by closing the windows and lighting the stove in winter… and with the glass windows improving lighting, we must have saved a lot of time.’

Jin Cheon-hee felt good seeing the room that had completely changed from before.

The sight of Zhuge Rin sunbathing while reading a book was so peaceful.

“Ah, Hee-ya.”

Zhuge Rin opens his mouth, sensing Jin Cheon-hee’s presence.

Jin Cheon-hee’s face reddened as he called him by the nickname. It’s not easy to adapt to being called by such a name at this age.

‘If I had biological parents, would it have felt like this?’

Divine Doctor Baek Rin, Zhuge Rin, said to Jin Cheon-hee:

“Come in. I can’t tell you how nice it is to be able to close the windows and use the stove. My body has truly warmed up. It feels like I’m soaking in a hot spring.”

“How are you feeling?”

“Until yesterday, I was coughing all day and my throat hurt, but now it’s subsided a lot. To think that a stove could be this good… Hee-ya. Now that I’m using it, I can immediately tell that what you made is truly remarkable.”

Zhuge Rin urged him to sit beside him.

‘The chair looks big because I’m small.’

Jin Cheon-hee’s small body wriggled as he climbed onto the chair.

Zhuge Rin smiled broadly, finding Jin Cheon-hee cute.

“How can our Hee be so smart and cute? No one has ever thought of using glass for windows to let in sunlight and raise the indoor temperature. The head of the Namgung family boasts so much about how great his successor is, but I bet those guys couldn’t even keep up with your toes.”

“Hehehe!”

“And what about this stove? It’s incomparably warmer than a fireplace or brazier, I wonder why we didn’t know about this until now.”

‘No, the reason glass windows weren’t used is because glass is extremely expensive in this era, and there’s no technology to make such large glass, Master.’

To begin with, he couldn’t understand how that extra Yoo Ho made glass windows in just one day.

‘And when did he make the stove while making the glass windows? Is he using alchemy or something?’

Jin Cheon-hee inwardly doubted Yoo Ho’s identity.

Realistically, making such glass windows in a day was absolutely no ordinary feat.

‘Yoo Ho… I’ll have to look into him later. They say his loyalty to Master is extraordinary, but something seems fishy. Still, seeing Master so happy makes me feel good too.’

It hadn’t been long since Jin Cheon-hee met Zhuge Rin. But Zhuge Rin was a person with an extraordinary love for his disciple, beyond imagination.

Look at him now.

Those doting remarks are enough to give one goosebumps.

“I only knew about medicine until now. I was a frog in a well. You’ve removed the scales from my eyes.”

Unable to bear the doting remarks any longer, Jin Cheon-hee said:

“Ahhh, Master, please!”

“What’s wrong?”

Master tilted his head and then said to the servant attending them:

“Ah, bring some sweets. Our Hee must be bored. He’s still young, he needs to eat a lot.”

At Master’s urging, the servant rushed to the kitchen.

***

Yoo Ho didn’t follow Jin Cheon-hee inside. But he hadn’t left either.

He had been standing there, carefully listening to the voices coming from inside the door.

And Yoo Ho sighed.

‘He’s been fond of Jin Cheon-hee since he first saw him, and now he’s completely doting on him.’

Who is Divine Doctor Baek Rin? He’s not only a peerless medical sage but also the last successor of the Zhuge family.

He’s a person who rarely smiles personally, except for the business smile he uses when necessary.

Moreover, perhaps due to his deteriorating health day by day, the medical pavilion was full of gloomy silence.

But since meeting Jin Cheon-hee, he’s been smiling non-stop.

‘So this is why people raise children.’

And he’s not just any child. He’s a child with many secrets.

As soon as he arrived, the child started changing the chilly atmosphere of the medical pavilion.

For Yoo Ho, it was a small but significant change.

There was also a practical change.

Zhuge Rin’s complexion had improved.

Zhuge Rin, who quickly loses body heat due to the Nine Yin Meridian Obstruction.

For such a Zhuge Rin, the heat inside that sealed house was precious and absolutely necessary for extending his life.

The glass window. And the bronze stove designed to exhaust smoke without leaking.

These two alone would considerably support Zhuge Rin’s health.

How much more excellent will it be when combined with the ondol heating method currently under construction?

That was extremely valuable to Yoo Ho.

‘I guess it wasn’t just empty words. But possessing such knowledge is suspicious. Master probably won’t care since he thinks he doesn’t have much life left anyway, but…’

Yoo Ho’s expression, lost in thought, turned frightening.

‘Jin Cheon-hee. If you truly save Master’s life, I’ll give you anything for your sake. Even if it’s this life of mine.’

An undetectable murderous intent flows out from between his narrowed eyes. But suddenly, his expression softened.

The sound of Zhuge Rin laughing comes from inside.

The murderous intent in Yoo Ho’s eyes quietly disappeared.

‘It’s been years since I’ve heard Master laugh…’

A smile appeared on Yoo Ho’s lips.
