The cool night breeze brushed against Zeyren's skin as he stood across from Fenrir, his body tense and aching from brutal training. He could barely lift his arms, yet here he was, facing off against a beast who wasn't even using his full strength.
Zeyren (thinking): Damn it… I already know I'm gonna lose, but if I don't push myself now, I'll never close the gap between us.
Fenrir's golden eyes studied him, his expression unreadable. Then, without warning—
WHOOSH!
Fenrir disappeared.
A chill crawled up Zeyren's spine as his instincts screamed—MOVE!
Too late.
BAM!
A powerful force crashed into his stomach, sending him flying backward. He tumbled across the dirt, coughing violently. His vision blurred as pain exploded through his ribs.
Zeyren (gritting his teeth): Damn it… this is completely one-sided…
Fenrir cracked his knuckles, walking toward him slowly. "You're hesitating. You're thinking too much. In battle, hesitation means death."
Zeyren forced himself to his feet, gasping for air. "I… I don't have anything that can help me keep up with you."
He hesitated for a moment before speaking. "Can I use my monsters?"
Fenrir shrugged. "I was planning to give you monster cores after the fight so you could absorb spiritual energy and train them with you, but at their current rank, they won't be much help in battle."
"They can't even level up much."
However… he paused, staring at Zeyren. "If you manage to survive the next 30 days and defeat Master, he might give you advice on how to evolve them beyond their limits."
A spark ignited in Zeyren's chest. Evolution beyond limits…?
Fenrir smirked. "But if you want, you can use them now and train them alongside you."
Zeyren clenched his fists. "Then… I'll use them now."
Closing his eyes, he focused on his Spiritual Domain, preparing to summon his monsters—
And then—

[Flashback] – The Second Domain
Zeyren's eyes snapped open, confusion washing over him.
Zeyren (shocked): Wait… what the hell is this? Why am I sensing another domain?
His surroundings blurred as his mind was pulled inward. Before him, two separate spaces appeared—
One was familiar, filled with the aura of his tamed monsters. The Spiritual Domain.
But the second one…
It was different.
A vast, mechanical world stretched before him, filled with gears, blueprints, and towering metallic structures—a Mental Domain that only Machine Masters could use.
Zeyren's heartbeat quickened. "System… what is this?"
System: "Didn't I tell you? Ohhh, I forgot! You have two domains. One is for storing monsters, and the other is for unlocking blueprints of advanced technology."
Zeyren: "You damn system! That's the kind of thing you should have told me earlier!"
System: "I didn't tell you because it's useless to you right now. Unlocking blueprints requires a ridiculous amount of SP—1000 per blueprint, to be exact. And let's be honest, you're broke."
Zeyren twitched. "…"
System: "Also, you're too weak to kill monsters for SP, and even if you had blueprints, you wouldn't be able to build anything. So why waste time thinking about it?"
Zeyren groaned, rubbing his temples. "You… You just didn't want me to know, did you?"
System: "...…."
He took a deep breath, pushing down his frustration. Fine. If I can't use it now, I'll deal with it later.
But then—
A thought struck him.
His eyes widened.
Zeyren: "Wait… Yesterday, you mentioned a lottery spin that I could access after 24 hours, right?"
System: "Oh… um… yeah, I guess I did."
Zeyren's eyebrow twitched. "It's been more than 24 hours. Why didn't you remind me?!"
System: "Uh… I forgot?"
The System's voice sounded nervous, as if avoiding eye contact.
Zeyren: "You're really pushing your luck…"
System: "W-Well, anyway! You can spin it now! Go ahead!"
He exhaled sharply. Whatever…
"Alright… Spin the damn wheel."

The Lottery Spin – A Game-Changing Reward
A glowing roulette wheel materialized before him, filled with various rewards.
Zeyren (praying): Please, please, please, something good… something I can actually use…
System: "Spinning…"
The wheel slowed…
And landed on—
System: "Congratulations! You have won a Blueprint for Body Part Enhancement!"
Zeyren blinked. "Wait… What does that mean?"
System: "You can choose any part of your body to enhance. It can be a mechanical armor upgrade, a reinforced limb, or even a fully artificial replacement."
His heart pounded. A body part upgrade…?
Zeyren (grinning): "I knew I might be broke and weak now, but I have luck on my side!"
Then, he looked at his left arm—or rather, the empty space where it should have been.
His breathing quickened.
Zeyren: "System… Can I create a fully functional artificial arm?"
System: "…Yes."
For a moment, Zeyren just stood there, stunned.
Then, without hesitation—
Zeyren: "I choose a left arm."
System: "Processing…"
A sudden surge of energy rushed through him as the blueprint activated in his Mental Domain.
System: "Even if you unlock it, you can't use it yet."
Zeyren smirked. "Did you forget? I have Mimix. He can transform into it."
System: "…Mimix needs to be at least Level 5 to mimic this blueprint. And even at Level 5, his endurance and power will be low. You'll need to invest SP or your own Spiritual Power to use the functions of the arm."
---
[Back to the Present] – The Fight Resumes
Zeyren spent the remaining SP to level up Mimix.
System:
Mimix: Level 2 → Level 3 → Level 4
Used: (15 × 3 × 2) 90 + (15 × 4 × 2) 120 = 225 SP
Remaining SP: 39
Zeyren (thinking): I need more SP to reach Level 5…
He turned to Fenrir. "Can you give me a high-level monster core for recovery?"
Fenrir tossed him a Level 55 Legendary Monster Core. "Make do with this. I'll give you better ones after the fight."
Zeyren grinned.
System: "+880 SP received. Total SP: 919."
Zeyren: "Upgrade Mimix to Level 6 and use the remaining SP on my Spiritual Power!"
System:
Mimix: Level 4 → Level 6 (225 + 270 = 495 SP)
Spiritual Power: Level 8 → Level 10 (180 + 200 = 380 SP)
Remaining SP: 44

[FINAL SCENE] – A NEW LEFT ARM & THE FIGHT CONTINUES
The cool night breeze brushed against Zeyren's skin as he stretched his new left arm, flexing his fingers. The artificial limb moved smoothly, its red glow flickering like a heartbeat.
Nyx, perched on a nearby tree, let out a sharp whistle. "Well, well, well… Looks like the brat just got himself something interesting."
Fenrir crossed his arms, golden eyes locked onto Zeyren. "You absorbed a Level 55 Legendary Monster Core in just an hour?"
Zeyren smirked, his red hand pulsating. "Yeah. You gave it to me, didn't you?"
Fenrir's eyes narrowed. "I expected you to use it for recovery, not to boost your power this much in such a short time."
Nyx burst into laughter. "Pfft—Rock Head, you seriously underestimated him! This brat's full of surprises!"
Zeyren rolled his shoulders, feeling the burn of his muscles. The red glow in his hand pulsed again as if responding to his intent. "So? Are we gonna talk all night, or are we gonna fight?"
Fenrir smirked. "Fine. Let's see if that new arm is just for show or if you actually learned something."
---
WHOOSH!
Fenrir vanished.
Zeyren's instincts screamed at him—MOVE!
Without thinking, he launched himself sideways—
BAM!
Fenrir's fist grazed past him, creating a gust strong enough to send dust flying. Zeyren barely managed to avoid a direct hit, but the shockwave alone numbed his left side.
He's so fast!
He didn't even have time to counter. Fenrir was already closing in—
---
A ONE-SIDED BATTLE
Dodge. Dodge. DODGE!
Zeyren threw himself backward, activating the energy burst in his left arm. A sudden red propulsion blast shot from his palm, launching him away just as Fenrir's fist smashed into the ground where he had been standing.
BOOM!
The ground cracked and cratered beneath Fenrir's strength, sending debris flying everywhere.
Nyx cackled. "Hah! Look at him go! He's just running for his life!"
Zeyren gritted his teeth. I can't land a single hit!
Gritting his teeth, he flicked his left wrist, firing a rapid burst of energy toward Fenrir—
BOOM! BOOM! BOOM!
The red blasts shot forward like explosive bullets—
But Fenrir didn't even move.
He stood there. Unbothered.
The attacks struck him directly—and did absolutely nothing.
Zeyren's eyes widened.
"Tch. That tickles." Fenrir smirked, stepping forward, completely unscathed.
Zeyren's stomach dropped. "No way…"
Fenrir vanished again.
Before Zeyren could react—
BAM!
A powerful kick slammed into his ribs, sending him flying. His body skidded across the dirt, leaving a deep trail before he crashed against a rock.
"Guh—!"
Pain exploded through his entire body. His vision blurred.
Fenrir approached casually. "You're fast, but you don't know how to use that arm properly."
Zeyren gasped for air, his arms shaking. His Spiritual Power was draining too fast.
If this keeps up, Mimix will revert back to a slime—and I'll lose my only advantage.
I have to end this in one move… But how?
Then—an idea hit him.

FINAL GAMBLE – THE LASER BEAM
Zeyren steadied himself, gripping his left fist.
One attack. All or nothing.
He funneled everything—his SP, his Spiritual Power—into his left arm.
The red glow intensified, shifting from a flickering aura into a condensed, focused beam.
Minimize the spread… increase the damage output… concentrate everything into a single point.
His breathing grew ragged. His entire left arm felt like it was on fire, but he held firm.
Fenrir raised an eyebrow. "Oh? What's this now?"
Zeyren didn't answer. He gritted his teeth and unleashed everything.
"TAKE THIS!!"
A blinding crimson beam tore through the air, slicing forward at terrifying speed.
The attack was so condensed that it barely made a sound, yet its sheer intensity burned the very ground beneath it.
Fenrir's body blurred.
In an instant, he vanished—dodging before the beam could reach him.
BOOOOOOM!
The beam tore through a reinforced training dummy behind him.
It didn't stop.
It kept going.
SHHHHHHHRRRRRK!
The reinforced metal cracked, then shattered completely as the beam pierced through it—
Then the boulder behind that—
Then the trees beyond that—
And even part of the reinforced wall in the distance.
Then, silence.
Everyone was speechless.
Zeyren panted, barely able to stand. His arm trembled, smoke rising from his fingertips.
I put everything into that…
Nyx's beak hung open. "...The hell was that?"
Fenrir turned slowly, staring at the destruction left behind. He let out a low whistle.
"Huh. That could've actually been dangerous… if you had better aim."
Zeyren groaned, dropping to one knee. He was completely drained.
His left arm pulsed one last time before Mimix lost its form, melting back into its original slime state and slumping onto the ground.
Fenrir smirked, walking toward him. "Not bad, brat. But you still lost."
Zeyren exhaled sharply, forcing a weak grin. "Yeah… but you dodged."
Fenrir chuckled. "Tch. Don't get cocky." He crossed his arms. "That attack had potential. Maybe after a thousand more attempts, you'll actually land a hit."
Nyx laughed. "Aww, is Rock Head actually impressed?"
Fenrir ignored him. He extended a hand toward Zeyren. "Get up. You've got a long way to go."
Zeyren gritted his teeth and took Fenrir's hand, pulling himself to his feet.
This was just the beginning.
