Chapter 6
The next day.
Yujin Magnus returned to the main house after a long time and met the butler, Jeffrey.
“It’s been a while, Young Master.”
Jeffrey greeted him with a mysterious smile.
…As expected, he’s hard to read.
Yujin thought that while looking at his narrow-eyed smile.
“Hello, Uncle Jeffrey.”
Yujin was still acting like a polite and bright young master in public, so he greeted him naturally.
“So, what brings you here?”
“I came to check my merit points. What rank am I now?”
Merit points were a system that measured how much a member of the Magnus family contributed to the family.
Depending on the score, their authority within the family would change.
“I see. I was just organizing that. Here, I’ll show you.”
“Thank you.”
Yujin checked his merit points.
Thanks to completing the Kalibor Magic Tower’s request, his score, which was almost zero before, had increased significantly.
And this score meant—
“You now qualify to enter the next floor of the ‘Infinite Library,’ Young Master.”
The Infinite Library was a place where all the knowledge gathered by the Magnus family over generations was stored.
That was exactly why Yujin came back to this annoying main house.
“Please guide me, Uncle Jeffrey.”
“Understood.”
The Infinite Library was located deep underground, heavily guarded.
Since the Magnus family was an alchemy family, they valued knowledge greatly, and countless books were stored there.
After passing the guards, Yujin met the librarian, Eloise.
She was a gloomy-looking woman wearing thick gold-rimmed glasses.
“Have you been well, Lady Eloise?”
“…More or less. And who is this…?”
“This is Young Master Yujin. He has earned enough merit points to gain access.”
“Ah… I see… With this score… you can access Security Level 2… up to the second basement floor…”
The library was divided into 10 security levels.
Level 1 could be accessed by anyone, but higher levels required higher merit points.
Level 10 could only be accessed by the family head.
“I’ll grant you access.”
When Eloise used magic, two key-shaped marks appeared on Yujin’s chest.
Jeffrey left, and Yujin entered the library.
The library had 10 underground floors, divided into sections like history, literature, religion, art, alchemy, and magic.
Yujin went to the magic section.
More specifically—
the area with 2-circle magic books.
He had already learned all 1-circle magic, but he couldn’t access 2-circle magic before due to lack of qualification.
But now—
“But now, it’s different.”
He finally had access.
Still, there was a problem.
The books were extremely expensive.
To borrow a book, you needed not only merit points—but also money.
“These crazy capitalists…”
Yujin couldn’t accept it at all.
“I can only borrow one… I have to choose carefully.”
He decided to choose an elemental magic.
The five main elements were:
Fire, Water, Earth, Light, and Darkness.
But—
they were too expensive.
“Why are they so expensive…?”
He couldn’t even afford them without going into debt.
“I can’t go into debt just to learn one magic…”
While thinking, his eyes stopped at one book.
[Lightning Field]
A 2-circle lightning magic.
It created a field where lightning continuously flowed.
Normally, it was used as a trap to shock enemies in metal armor.
Because of its limited use, it was cheap.
“Lightning…”
Yujin thought.
Lightning magic was powerful, but hard to control and easy to block.
So it was underrated.
But—
“I already used lightning for electrolysis.”
And—
“If I want to surpass others, lightning is my only path.”
Electricity was something he deeply understood from his previous life.
But in this world, people only saw it as “lightning.”
Their understanding was primitive.
“I definitely understand electricity better than anyone in this world.”
Also—
“If I focus on one element… lightning is the right choice.”
After thinking for a long time—
“…Yes. This is the answer.”
Yujin picked up the Lightning Field magic book.
At Workshop 43
“What book is that, Young Master?”
Edgar asked.
“It’s a 2-circle magic book—Lightning Field.”
“…Lightning Field? That’s difficult and dangerous…”
Edgar looked worried.
But—
“This is easier than I expected.”
Yujin was surprised.
The theory was extremely simple.
This world only understood electricity at the level of “lightning.”
Even middle school science was more advanced.
But—
“The magic control part is what matters.”
That part was useful.
After learning, Yujin tried casting the magic outside.
He created a field in the air.
Lightning spread outward in a spherical shape.
“This is basically an electric sphere…”
Then suddenly—
“Wait… isn’t this like an electric field?”
An idea flashed in his mind.
“If I can create an electric field…?”
Yujin immediately ran to the electrolysis setup.
Later
Edgar was worried.
Yujin had been working nonstop.
Making aluminum required constant magic input.
It was extremely exhausting.
“I wish I could operate that device myself…”
Edgar entered the workshop.
Then—
“Eh?”
The electrolysis device was working on its own.
Aluminum was forming without Yujin.
“What is going on…?”
At that moment—
“Ah, there you are, Workshop Master.”
Yujin entered.
“Why is it working by itself…?”
“Oh, the magic is holding? That’s great!”
Yujin checked happily.
“It’s because I applied the Lightning Field magic.”
“…What?”
Edgar was shocked.
That magic was supposed to be for attacking enemies.
Yujin explained at length—
“Lightning Field is basically an electric field…”
Edgar didn’t understand a single word.
But—
“At least… the Young Master can finally rest.”
That was enough for him.
“Now aluminum production will become faster.”
Yujin concluded.
Then Edgar said—
“Now that production has increased, shouldn’t we promote aluminum to other Magic Towers?”
Yujin nodded.
“That’s a great idea. Let’s do it.”
A few days later — Workshop 35
Raisha showed a silver metal to Cassian.
“I heard that half-commoner made this.”
“…What is it?”
“It’s called aluminum. A Magic Tower asked us to check if it’s real.”
Cassian looked at it.
Then—
“Trash. Throw it away.”
“What? But shouldn’t we analyze—”
“No need. It’s light and weak. Useless.”
He dismissed it.
Raisha agreed.
They ordered it to be thrown away.
“Making something no one wants… his end is near.”
Cassian smirked.
Back at Workshop 43
“Young Master, someone from the Cartier family has arrived.”
“The Cartier family?”
They were one of the top jewelry families in the Empire.
Yujin was confused.
He met the visitor.
“This is an order from Ellen Cartier.”
“The head herself…?”
Yujin checked the document.
They wanted to use aluminum to make jewelry.
“They want to use aluminum… for accessories?”
It didn’t make sense to him.
But then—
he saw the payment.
“….”
Yujin froze.
“…They’re paying this much?”
