Chapter 11
The next master of the Kalibor Magic Tower, Ivrin Kalibor.
She was researching flying objects, and was using a lightning spell—where lightning elements flowed in a dense spiral form she had developed—to lift an aluminum flying object into the air.
She believed that by using this magic, based on the compatibility between lightning elements and metal, she could save humanity from the evil grasp of penguins.
“That’s really amazing. I never thought magnetic force could be controlled this precisely.”
Until she heard Yujin’s words.
“…Is it really magnetism?”
Ivrin muttered with a trembling voice.
Magnetic force.
As far as she knew, it was a force created by magnets.
A metal called magnetite, which naturally contained magnetism, could pull or push other metals.
That was all she knew.
But—
‘If the reason lightning affects metal is actually magnetism…?’
Most believed that lightning magic affected metal simply because of good compatibility.
But what if it wasn’t just compatibility—
what if the flow of lightning created magnetism?
If that was true, it would also explain why it only affected metal.
“…Wait. I think there was a magnet nearby…”
Ivrin picked up a magnet and began experimenting.
This time, she placed the magnet outside and brought the spiral current closer to it.
And then—
“…This really is magnetism, isn’t it?”
She was shocked.
Depending on the polarity and position of the magnet, the electric magic either pulled, pushed, or even rotated.
Her magic was behaving just like a real magnet.
Watching her—
‘…Come to think of it, this world hasn’t discovered Ampere’s Law yet?’
Yujin was also surprised.
Magnets existed. Magnetism existed.
So he naturally thought the relationship between electricity and magnetism was already known.
After all, in his previous life, it was basic education.
But thinking about it—
that discovery was actually quite recent.
So Ivrin’s reaction wasn’t strange at all.
“…How is this possible…”
Ivrin stared blankly at Yujin.
“…How did you know?”
“Ah… well… I just had a feeling.”
“A feeling…?”
“When I saw that aluminum plate… flying like that, it felt similar to how magnets push things up. So I thought it might be magnetism… but I didn’t expect it to be true. Haha.”
Yujin laughed.
“I see… But I need to test more, but if this is true… this is a huge discovery…”
Ivrin looked troubled.
“If it’s about credit, don’t worry. I just said it casually.”
Yujin didn’t care about academic credit.
What mattered more was building a good relationship with the future master of the Magic Tower.
But Ivrin shook her head.
“No, this is a discovery that will go down in the history of magic. I’ll definitely put your name on the paper. Maybe it’ll be called the Yujin–Ivrin Law?”
“…You don’t have to…”
“No, this kind of thing must be clear. Also, if you want anything, just tell me.”
“…Then… could you teach me that magic you just used? I’m interested.”
Yujin had a reason.
He wanted:
- A good relationship with the future master
- Magic that couldn’t be obtained from the “Infinite Library”
This magic was Ivrin’s original creation.
So it was perfect.
“…You want to learn this? Wow, you’re really serious about magic!”
Ivrin looked touched.
“No one in the tower asked to learn this… so I was a bit sad. But you’re so eager—even though we just met. I’m really touched.”
“Haha… I’ve always liked magic.”
“If you’re that serious, I have to teach you. I’ll make sure you learn it quickly.”
“Thank you, noona.”
“Of course. Oh, I haven’t named this magic yet. Do you have any ideas?”
“…Hmm… how about ‘Coil Lightning’?”
Because the electricity was shaped like a coil.
Also, he wanted to keep terminology consistent.
“Coil Lightning… that sounds great! I like it!”
And so, Ivrin began teaching.
“The most important thing is to imagine a spiral pipe in your mind. The lightning flows like water inside it…”
Yujin imagined a coil and wires instead.
That part was easy—
but controlling mana was difficult.
So Ivrin directly guided the mana flow inside his body.
After that—
“Wow, you’re really talented! This is a high-level 3-circle spell, but you learned it so fast!”
A tightly wound current appeared in Yujin’s hand.
He had successfully learned Coil Lightning.
“It’s thanks to your teaching.”
“A good teacher is made by a good student. Honestly, I wish you would join our Magic Tower.”
“Haha…”
Yujin just smiled.
“I’ll go plan my experiments. I’ll contact you later!”
“Yes.”
Ivrin left.
Then—
“Everything is ready. Come to my lab for a moment. It’s on the top floor!”
Robak’s voice echoed.
“I understand.”
Yujin headed to his lab.
Inside Robak’s Laboratory
‘This should be the best magic to teach…’
Robak prepared to teach Mid-Level Mana Stone Creation.
Mana stones—
they stored mana for later use.
They were essential for artifacts.
Low-level methods could be learned.
But mid-level?
Only taught to chosen disciples.
Because:
- Efficiency depended on technique
- Element compatibility changed
- It affected artifact performance greatly
“A mage who can create mana stones can survive for life.”
They were always in demand.
That’s why Robak chose to teach this.
“Welcome. This is my lab.”
It looked similar to an alchemy workshop.
Books. Materials.
But also—
complex magic circuit blueprints.
“Interested?”
“Yes. What is this?”
‘Perfect timing.’
Robak decided to explain.
“This is an artifact designed to create light-based forms…”
He explained:
- Mana flow
- Light interference
- Circuit structure
It was like creating 3D light illusions.
Using:
- Gems
- Mana circuits
- Flow control
But—
‘This might be hard for him…’
Artifact design required genius-level talent.
Even Robak took a lifetime.
Meanwhile—
Yujin thought:
‘…This is basically circuit design.’
It was complex—
but familiar.
In his previous life, he designed experimental boards.
Because his professor forced him to.
“…I expected more from you.”
Those words made him study all night.
Now—
he understood this easily.
‘What a waste of time that was…’
Looking at Robak—
‘It would’ve been better to have a teacher like this…’
“…That’s why I needed pure gold.”
Robak pointed to a complex circuit.
“Yes… that makes sense.”
The density was high.
Low purity would cause instability.
“After this part, the mana flows like this…”
Yujin suddenly noticed something.
‘Wait… this design is dangerous.’
“Sir, this part…”
“What is it?”
“If you leave it like this, won’t excess mana reduce the artifact’s lifespan?”
“…Hmm? I don’t think it’s a big issue.”
“But this amplification rune keeps increasing output, right? Then during certain operations, overload might happen again.”
“…What?”
Robak quickly calculated.
‘…He’s right.’
There was a real risk.
And yet—
‘He understood this just from my explanation?’
Then—
“If you add a feedback circuit here, it could adjust the amplification based on mana flow…”
Yujin drew a simple concept diagram.
Not perfect—
but enough.
“….”
Robak was shocked.
‘…This level of insight… from someone seeing it for the first time?’
In his entire life—
he had never seen such talent.
In design, of all things.
And that made it even more unbelievable.
