Chapter 120.
Don’t Realize It!
Bounce. Whoosh.
Tap tap tap!
Yu So-young conducted a series of tests—starting with jumping jacks, then aerial flips, an all-out sprint, and a sudden halt—right in the middle of the Reboot Center.
While Ham Manager’s eyes widened in astonishment, Park Deputy unconsciously took a step backward.
“What is she doing right now?”
“Is that… really Dr. Yu?”
Looking closer, Yu So-young appeared utterly absorbed in her testing, her expression radiating pure delight.
Tap, tap! Whoosh!
Then, folding her body in mid-air while still wearing the auxiliary frame, she executed a perfect tumble.
Ham Manager blinked repeatedly, muttering to himself.
No way.
“Tumbling is necessary for auxiliary frame testing?”
By any measure, this was absurdly acrobatic for what should have been a test!
Doo-ho himself stood slack-jawed, watching the spectacle unfold.
At that moment, Bom-i, camouflaged atop Doo-ho’s shoulder in work clothes colors, spoke softly.
-Master.
“Hmm?”
Puff…
Bom-i puffed out her cheeks slightly.
-That’s not a mentor—that’s a woman who’s lost her mind, ribbit.
Well…
The embarrassment falls on me.
But then again.
‘From my experience, she wasn’t like this at all.’
Just then, Hawkeye’s voice slipped into my mind.
-She must be Seol Ye-na’s aunt.
Blood will tell, as they say.
I… suppose so?
As Doo-ho was coming to terms with this, Isto’s remark jolted him back to attention.
That one, that one.
-She’s even more of an attention-seeker than you, sir.
Yikes!
‘I can’t let him say things like that.’
Even as Doo-ho silently rebuked Isto, Yu So-young showed no signs of stopping.
This time, she planted one leg firmly and twisted her body with tremendous force.
At that moment, the assistant’s voice rang out.
-Should we continue with the limit tests?
Yu So-young’s lips curved upward.
“Can you keep up with me?”
-I’ve been doing that from the start.
Yu So-young clicked her tongue.
‘Where did he get an AI like this?’
A thought struck her suddenly.
‘This isn’t a joke—if this launches, exoskeleton companies are going to be screaming.’
Yu So-young leaped even higher this time.
She folded her body mid-air, and just before landing, the assistant spoke rapidly.
-So-young, twist your waist just slightly.
The auxiliary frame shifted subtly, smoothing out her movements seamlessly.
Thud.
As Yu So-young landed, she couldn’t help but laugh in astonishment.
‘How is it catching that in real time?’
As the limit testing continued.
The assistant spoke with a regretful tone.
-So-young, I’d like to test more, but if the smart actuator takes any more load here, it might become dangerous.
“Ah, I see.”
Looking at the time, it had already been fifteen minutes.
As Yu So-young stopped moving, the auxiliary frame slowly lowered its posture.
The locking mechanisms at her waist and knees positioned themselves to release in sequence for easy removal.
Sigh.
It really did everything perfectly until the very end.
Yu So-young gazed down at the auxiliary frame.
‘…I want to buy one too.’
As an emergency support device.
Noticing eyes on her, she glanced around.
From Ham Manager to Na Manager, who had somehow appeared at the doorway.
They were all watching her.
Gasp!
‘Have I lost my mind?!’
That’s how exceptional Lim Doo-ho’s auxiliary frame modifications were.
Yu So-young quickly cleared her throat.
“Ahem. The test results are….”
Yu So-young displayed an interim evaluation window on her smart glasses.
After completing her assessment, she spoke.
“It’s unfortunate that there’s no score higher than perfect.”
At those words, Ham Manager’s face brightened considerably.
“You hear that, Park Deputy?”
“Our ace, as expected…!”
When both of them showed such genuine enthusiasm, Yu Doctor turned back.
“I apologize. I’ve been quite intrusive in someone else’s workshop.”
Ham Manager and Park Deputy quickly waved their hands in dismissal.
“Oh no, not at all.”
“Thanks to you, we got to see something wonderful… or rather, conduct a proper test.”
Yu Doctor hesitated for a moment, then looked at Doo-ho, who was scratching his cheek.
“Lim Doo-ho.”
“Yes, Doctor.”
“I know this is sensitive, but could I see the assistant app?”
Na Manager’s eyebrows, standing by the door, shot up.
‘Wait, that’s not something we should show, is it?’
Just as he was about to step forward.
“You’re welcome to see it.”
Doo-ho agreed far too easily.
Immediately, smart glasses and a mirrored holographic workspace unfolded across the work table.
Na Manager’s eyes widened.
Lim Deputy!
‘Why are you showing that?’
He seemed worried that the technology might be stolen.
Yu Doctor quickly peered into the holographic workspace.
Hmm… uh…
The more he examined it, the worse his expression became.
Na Manager, wondering if something was wrong, quietly stepped back, and Yu Doctor turned his head.
“Lim Doo-ho. What exactly is this?”
Doo-ho pondered for a moment before opening his mouth.
“I just modeled it after the human brain, and it seems to work quite well.”
“…The human brain?”
“Yes. Humans normally have their subconscious handle most processes. Then they concentrate only when necessary.”
Doo-ho pointed to the holographic workspace.
“So I developed the OS to run on the subconscious, with the AI only activating when concentration is needed.”
“Wait a moment.”
Yu Doctor pressed his forehead.
Good heavens.
‘He developed a situational awareness architecture all by himself?’
Was that even possible?
This young man standing before him was describing something that would require hundreds of billions in investment from massive corporations.
Yet absurdly, the algorithm displayed in the hologram before them was a form he’d never seen before.
So he couldn’t help but believe it.
If what Lim Doo-ho said was true.
Yu Doctor recalled the sensation he had just experienced.
The twist of her waist just before landing—a reflexive response.
The judgment to isolate only the parts that would strain her.
The way she naturally accepted limit testing.
Intuition.
An odd word to attach to a machine, admittedly.
‘But that’s definitely what I felt.’
She gazed once more at the window Doo-ho had opened.
A structure incomprehensible no matter how many times she examined it.
Yet somehow it appeared simple.
A sudden thought crossed her mind.
‘Could this be a sign of a singularity?’
She pressed her lips firmly shut.
It wasn’t something to voice carelessly.
Meanwhile, Doo-ho found himself briefly recalling the days when he’d developed the assistant.
Hmm….
‘Truth be told, I was holed up in the Garage for fifty days developing the assistant.’
.
.
.
Not long ago, inside the Garage.
When Doo-ho decided to attempt substituting part of the mana circuit, it was Isto who raised his hand first.
But….
Doo-ho quietly averted his gaze.
In an instant, Isto’s LED eyes widened.
-Why are you avoiding my eyes?
“…You’re too much for this.”
-Isn’t that an advantage!
Ugh.
“I’m worried a troublemaker will emerge instead of an assistant.”
-Don’t you trust me, sir?
“No.”
-That’s too blunt!
Too blunt, indeed.
‘After you turned my words into crap and reported them to Wang Zhuxi!’
Doo-ho had happened to see a meme where Ghost dropped a poop-shaped meteor on Wang Zhuxi’s head.
Anyway.
Hawkeye would probably only care about efficiency.
And Meteor….
Seemed likely to keep slipping into sleep mode rather than provide auxiliary mechanics.
So Meteor was completely out of the question.
Eventually, my gaze settled on Bom-i.
Croak.
Bom-i puffed out his cheeks.
Master.
-Why are you looking at me, croak?
“Out of the four of you, you have the most easygoing personality.”
-I knew you understood, croak!
“Well… except for the explosions.”
-Croak?
In any case, the auxiliary frame’s companion wasn’t meant to surpass the user—it was meant to support from the side and catch you if danger arose.
‘I have no choice but to trust Bom-i in the support role.’
Bom-i climbed onto the workbench.
Whoosh.
I wrapped part of Bom-i’s mana circuit with the Soulbot.
At first, I thought it would be converted into electronic circuitry.
But then.
What was transferred wasn’t an electrical schematic—it was a structure closer to code.
“…Why is it coming out like this?”
Then a fragment of mana circuit that had been drifting through my mind clicked into place.
Based on that, I inferred that even within mana circuits, those governing the brain and those woven into the body had different properties.
After that.
I interpreted the converted code and developed a blank-slate companion.
I first trained it with standard educational data.
Then I added movement data from Father and my mentor Jang Moon-seo.
And finally!
‘I spent time in the Garage wearing the auxiliary frame directly and tuning the companion.’
That entire process took roughly fifty days.
Well.
‘It was only possible because it was the Garage.’
Through that process, I was beginning to dimly understand something.
‘What it meant for a Mechromancer to breathe life into machines with a Soulbot.’
.
.
.
I shook off my reverie.
Glancing to the side, Dr. Yu hadn’t taken her eyes off the hologram workspace.
Dr. Yu bit her lip firmly.
‘Is it really the right decision to submit this as an entry?’
Performance-wise, there were no issues.
No—it far exceeded expectations.
‘That’s exactly why it’s more of a problem.’
During the Global Competition, I couldn’t help but wonder how many temptations would come Lim Doo-ho’s way.
As his mentor, I was deeply concerned.
Moreover.
‘We might even lose our best human resources to overseas….’
The moment I turned around, my eyes met Na Manager’s.
I was about to nod and leave when I looked at Na Manager again.
“Excuse me, Na Yong-seok.”
“Yes, Dr. Yu.”
“Could we talk for a moment?”
“Of course. Let’s do that.”
Just as the two of us were about to leave, Doo-ho asked carefully.
“Doctor, what should I improve before the next evaluation?”
I froze in place.
‘What more could he possibly do!’
I nearly screamed internally.
I’d only mentioned the indicator, yet something absurd had materialized.
If I suggested he refine the functionality further, who knew what he’d bring next….
This was the first time I’d felt this terrified as a mentor!
I managed to compose my expression.
The appearance….
“Why don’t you refine it a bit?”
“Ah, I see.”
“No, don’t get any ideas!”
“Pardon?”
I snapped irritably and quickly added.
“Just make very, very minor adjustments.”
“Understood.”
Only then did I leave the Reboot Center with Na Manager.
* * *
A Cafe across from the Management Bureau Building.
“Then I’ll be going now.”
Even after Dr. Yu left the Cafe first, Na Manager remained seated for a while.
Her words continued to echo in his ears.
「During the Global Competition, there will be many people targeting Lim Doo-ho.」
In fact, the software he’d just witnessed was at a level that even major IT companies couldn’t easily replicate.
That’s why she was worried, and frankly, even frightened.
Sigh.
Na Manager rubbed the bridge of his nose.
To be honest.
‘I can prevent the technology leak, but….’
I gripped my head with both hands.
Lim Doo-ho.
“Why does everything come so easily to him…!”
The startled people around me stared.
As I bowed my head in apology, my stomach twisted painfully.
Stress-induced gastritis flared up again.
Na Manager pulled out a small medicine bottle from his pocket.
I swallowed the medication without water.
Sigh….
My stomach aches.
“Should I prevent him from going to the competition?”
But then the image of Lim Doo-ho preparing so diligently kept nagging at me.
No. I couldn’t prevent him from competing.
The Hunter Management Bureau couldn’t arbitrarily obstruct Lim Doo-ho’s path forward.
Yet I had no intention of letting his technology be stolen either.
‘He definitely said he wanted to mass-produce the auxiliary frame after the competition.’
A place where Lim Doo-ho wouldn’t waver.
A place he’d think of before any overseas temptation.
A place where his heart would bind most easily.
The answer wasn’t difficult.
“I need to pay more attention to Lim Doo-ho’s father.”
Na Manager immediately manipulated his smartwatch.
Soon, a hologram of Doo-ho’s father, Lim Tae-sang, materialized in the air.
Aigo~.
“It’s me, younger brother Yong-seok!”
-Huh? Ah, yes.
“Come on, we agreed to call each other hyung and dongsaeng over drinks last time, and you’re acting like this? I’m hurt.”
-Did, did I really say that?
How would a drunk man remember?
So then.
“Hyung Tae-sang!”
-Aigo, I’m sorry. No, I apologize, dongsaeng Yong-seok. I think I drank too much that night.
Yes!
Na Manager clenched his fist.
What I needed right now was.
‘To butter him up like crazy!’
“Hyung, I’m thinking of visiting your factory right now.”
-Wow, come. No, come! I actually needed some help anyway.
“Hahaha! Is that so?”
-That employee who works with him was formerly a Terraform… no, a Terraformer? Anyway, something like that is showing up in the system, but what would I know about such things.
“A, a Terraformer?”
Na Manager’s hand moved toward his stomach.
The medicine he’d just taken already felt insufficient.
Why.
How is it!
There’s never anything ordinary around Lim Doo-ho…!
Then Lim Tae-sang called out.
-Yong-seok, brother?
“Ah, yes! I’m coming right now.”
Na Manager shot up from his seat.
I can’t even manage being a superior to someone so accomplished.
