I Became a Scoundrel From a Wealthy Family 161

## Chapter 161 – 16. Gominji’s Night.

+++

It took a total of 36 hours to manufacture the RK-99 sample.
There were quite a few cumbersome tasks in between, and I had to keep changing the temperature every 12 hours, so I had to keep hovering around the chemistry lab.

But since it’s my house, it wasn’t boring or anything.
If I got bored, I could just fill the next room with secretaries and laze around, or go bother Danto, or watch the collaboration between Ha Eun-young and Ma Yeon-joo, or get reports on how the various things I had started were going.

There were plenty of things to do.

Anyway, after spending time like that, the final process was finally completed.
I took the RK-99, which had been pre-shaped and baked, out of the kiln.

The shape I had made was a round cylinder about the size of a soju bottle cap.

Ssshhh.

It was emitting a lot of heat and white smoke.
It looked like dry ice with water poured on it.

I carefully placed it on a dish.

“…Ah.”

But there was a very big problem.
I didn’t know how to check for superconductivity.

I only knew how to make it, but I had no idea how to test it or prove it.
This was a complete disaster.

‘Was there something about…negative? Something like that.’

In times like this, you can just pass the buck to a competent person next to you.
Probably.

“Seol-ah, you know how to test if this is a superconductor, right?”
“Yes.”

Fortunately, Baekseol said she knew how.

“Basically, we measure electrical resistance, and measure the Meissner effect and AC magnetic susceptibility. If superconductivity is confirmed during the test, we also measure the critical magnetic field and critical current. It’s a test of how much current and magnetic field it can maintain superconductivity under.”

For some reason, she explained it in quite a long and detailed way.
I wonder if this girl noticed that I don’t know how to test it.

“Okay. Do it.”
“Now? Without cooling it down?”
“Yeah. That’s the finished product.”

Baekseol tilted her head for a moment.

“…I need equipment.”

Then she rummaged through the lab for a while.
Fortunately, it was a space equipped with a full set of basic equipment, and the test didn’t require anything too fancy, so it didn’t take long.

“This is a resistance measuring device using the four-point probe method.”
“Uh. Okay.”

Baekseol grabbed the RK-99, which looked incredibly hot, with her bare hands and placed it on the sample holder of the measuring device.
Then she touched the four probes to it.

“Two are current electrodes and the other two are voltage electrodes.”
“Okay.”

Baekseol fiddled with the settings on the power supply.

“Generally, superconductors only exhibit their properties at temperatures close to absolute zero. Even -130 degrees Celsius is considered a high-temperature superconductor. Of course, if you apply a very high pressure of over 100 gigapascals, you can make it superconduct even at ultra-high temperatures.”
“Ultra-high temperature? How much is that?”
“Minus 30 degrees Celsius. That’s the superconductor currently used in 8th generation mechas.”
“I see.”

Minus 30 degrees Celsius is ultra-high temperature…
But what is a gigapascal?

“But this one has a surface temperature of about 80 degrees… and it’s even at atmospheric pressure. Nevertheless, if this is superconductive, it’s an incredible discovery that will change the history of mankind, just like you said.”

Considering that’s what she thought, Baekseol’s expression was bland.
Her eyes seemed to have no emotion.

Was she thinking it would fail, or was she just not showing any expression?

‘She’s explaining it to me in detail, so she must have noticed that I don’t know much about it.’

She probably doesn’t believe it.
There’s no way that something made by a guy who doesn’t even know what a superconductor is would be superconductive.
That’s probably what she’s thinking.

That ungrateful girl.
Even if I don’t know much about superconductors, the recipe is real. You faithless girl.

“If the resistance is 0, then V=IR, so even if you apply current, the voltage drop should be 0.”
“What’s that?”
“V is voltage, I is current, and R is resistance. Since the resistance R is 0, the voltage V naturally becomes 0.”
“I see.”
“In an experimental environment, it may not be measured as exactly 0V due to the sensitivity of the measuring equipment or external factors. Considering that…”

Baekseol fiddled with the panel again.
Her eyes widened slightly.

“…The voltage is 0. For now, the resistance value is 0 at this current.”
“Oh.”

But the reaction was more bland than I expected.
If the resistance value is 0, isn’t it a superconductor?

“Hmm.”

Baekseol fiddled with the measuring equipment for a long time.
She tilted her head and applied current several times, wrote down the results, and then suddenly put her finger on the surface of the RK-99 and pressed down hard.

“The resistance is 0 even though the surface temperature is close to 80 degrees… The critical current value is also high… For now… This alone is enough to guarantee a Nobel Prize.”
“Oh, really?”
“Yes. If it can be reproduced, that is.”
“Of course it can be.”

Baekseol took a pose with her chin in her hand, like a detective, and stared at the sample for a while.

“…How did you make it?”
“You saw it next to me. How to make it.”
“No…”

She picked up the sample and checked it.
Her expression was still blank, but her eyes were a little wider.

“You’re saying that if you grind copper, sulfur, and lead and bake them, you get a substance with 0 resistance?”
“Yeah.”
“…”

She still doesn’t believe it even after seeing it.

“It can’t be this easy… It feels like physics is being completely denied.”
“Anyway, the voltage is 0, right? Do the next test.”
“…”

Baekseol bit her lip, put away the measuring equipment, and prepared for the next test.

+++

“Voltage clear, Meissner effect clear…”
“Which means?”
“It’s a superconductor… It’s correct…!”

Baekseol looked noticeably more flustered than before.
Confusion and surprise crossed her face.

She picked up the RK-99, which was now slowly cooling down, with her hands.

“This simple thing… is a superconductor…”
“Okay. Then the test is over. Now I have to make the real goal.”
“Yes?”
“That was just a side project. The goal is to create a material to make a necklace to give to Minji noona.”
“A room-temperature, ambient-pressure superconductor… is a side project…?”
“You can have that one. It’s the first superconductor I’ve ever made, so I’ll give it to you.”
“You made it for the first time?”
“Yeah.”
“…”

She was even more confused.
She couldn’t understand it at all.

To be honest, I think I would be the same, but I can’t say that I’m a possessor, can I?
I’m not confident that I can convince her of that.

I have no choice but to gloss over it.
Doesn’t Baekseol think of me as a genius of the century?

“Actually, I’ve known the recipe for a long time. But I can’t make it, can I? If I don’t have the power and I make something like this, it’ll be a big problem.”
“…Certainly, it’s not something you can make carelessly.”

She clenched the RK-99 in her palm.

“Do you think you can protect it now?”
“Because you’re here.”
“…!”
“It’s still a bit lacking, but I feel like I can worry less because we have Seol-ah? I wonder how itchy my mouth has been all this time.”
“Yes…”
“Anyway, it’s not the time yet, so only you know about it. I’m going to release a new material while making this necklace, and I’m going to start a chemical-related company with it. I’m going to slowly build the foundation.”
“Yes. I understand. I’ll study and prepare as much as possible.”

Our Seol-ah has a lot to study.
She also has to study medicine.

It took another day to make the material for the necklace to give to Go Minji.

“Wow… This, this is…”
“Yeah. This is the new material, RK-77. Amazing, right?”
“It’s so pretty…”

Sua held the round object as if possessed.

This was also made by grinding and baking copper, lead, and sulfur, just like RK-99, but it became a completely different material from RK-99.
Like a jewel.

This is actually physically impossible.
You grind copper, lead, and sulfur and bake them, and you get a superconductor, and if you change the magnification, temperature, and time a little, this time a jewel pops out??

It really doesn’t make sense.
Since it’s a game world, I can just gloss over it by saying, “Oh, that’s how it is…”

Anyway, RK-77 is a jewel that contains the universe.
There are jewels in nature that give a similar feeling, but this one has the universe flowing inside.
When you actually see it, it’s really mysterious and strange, and your consciousness is endlessly drawn into it.

Like being brainwashed.

Of course, it doesn’t have that function at all.
It’s just a pretty pebble.

But that’s what a jewel is, right?
A pretty pebble.

“I’m going to process this and make it into a necklace.”
“This… will have an effect.”
“The way to make it is very simple, right? Automation is also possible, so if the reaction is good, I’ll just start a company and mass-produce it.”
“I think it will definitely work. I want to buy it now.”

Sua was already almost completely mesmerized.

“What’s its name?”
“RK-77.”
“…”

Then, after hearing the name, her expression turned sour.

“Do you… have to give it that name?”
“Then what should I call it? Should I call it Im Sua?”
“Hup…!”

Oh.
Now that I think about it, that’s not bad?
There are quite a few materials derived from RK-99.
I can give them the names of my favorite playthings.

‘So, RK-99 is Baekseol? RK-77 was made because of Go Minji, so I’ll call it Go Minji… Is that how it is?’

“I, I think it’s a little… that… It’s a gift for the young lady…”

Sua twisted her body.
She seemed to feel good when she imagined it.

“That’s right, isn’t it? Then I should call this Go Minji.”
“…”

She’s disappointed.

You little rascal.
Cute.
