Chapter 208: Serum Delivery

Chapter 208: Serum Delivery

Zain smirked as he now knew that Scavratt had become stronger thanks to the serum

He turned to the serum, grinning.

"System. You scanned the serum. That means you know how it works."

He paused, thinking carefully, then nodded once.

"So if you know how it works, then you can recreate it. Duplicate it."

He raised his hand slightly, changing the hack a bit.

"Put a copy of that serum into my system storage. But don’t just make a raw copy."

His eyes narrowed.

"Change it. Fix whatever made it unstable. I want a version that works every time."

Zain then lowered his hand, smirking.

"System. Do it now."

Zain watched the system window flash in front of him.

When the status changed to complete, he smirked.

"Good. It worked."

He opened his system inventory and pulled out a small container.

The vial inside pulsed faintly with dark orange liquid.

It looked heavier than normal serum, thicker, more alive.

He turned it in his hand and watched the light flicker across the surface.

"So this is it. The serum that can give someone a class."

He crouched down and tapped the vial lightly.

"And not just any serum—this one works every time."

His eyes narrowed slightly.

"It may not let them evolve beyond that class, but most people never even get one in the first place."

He stood up and looked into the distance.

"A lot of people out there are stuck. Powerless. Forgotten."

"Blazren is one of them. He’s already strong, but what he lacks is a class."

"Just one dose of this..."

Zain smiled to himself.

"That’s enough to shake the balance."

He spun the vial between his fingers and tucked it back into storage.

"Now it’s time to act."

He opened the system window again.

"Let’s begin phase one of the plan."

---

The black wolfman stood still inside the shadows of a crumbling rooftop.

His breath was quiet, calm.

Just like Zain predicted, he had come.

The chaos down below was part of the plan, but he didn’t expect it to drag on this long.

His eyes narrowed, locked onto the fight in the distance.

"Still no sign of him..."

He crouched, claws resting on the metal edge, tail flicking once.

"Heavenly Demon... where are you?"

He traced his gaze to Blazren, now limping slightly, his flame aura flickering irregularly.

"You should’ve come by now," he muttered.

"Blazren’s the one who promoted you. He vouched for your power."

"You’re supposed to protect your allies..."

He leaned forward, squinting through the smoke.

"Or maybe... are you testing me?"

He let out a low growl.

"Are you watching right now? Waiting for something?"

His ear twitched. Another impact shook the street. Scavratt was pushing harder.

"Damn. If you’re not going to show, then so be it," he muttered.

"This test... was enough."

He turned, stepping back into the darker parts of the rooftop.

His voice dropped lower.

"At least now we know it works. That serum—it’s more stable than I thought."

"One percent survival, yet Scavratt’s still going."

He started walking, shadows clinging to his legs.

"A failed gang rat turned into a beast-class monster..."

He stopped mid-step. His body was locked in place.

Below, Blazren’s flame aura suddenly pulsed—hot, loud, alive.

The wolfman looked back, eyes widening.

"What the hell..."

Blazren, barely standing seconds ago, was now bracing both arms forward.

His whole frame burned in unstable waves. His chest glowed faintly.

The air around him shimmered from pressure and heat.

"That’s not [Flame Punch]... no, that pressure..."

The wolfman clenched his claws.

"Did he activate [Infernal Drive] already...? No. That’s something else."

He took a cautious step closer to the edge, eyes fixed.

"Don’t tell me you’re trying to self-detonate just to take him down..."

"Blazren, you old fool."

He exhaled sharply and scanned the rooftops across from him.

"...Still nothing from Zain."

Then his jaw tensed.

"No matter. If the Heavenly Demon won’t show..."

"Then I’ll make sure the next experiment forces him to."

Meanwhile, Zain stood on a quiet rooftop just above the fight.

His eyes were on the system screen floating in front of him.

Zain crossed his arms and chuckled under his breath.

"So cheap. Only 1,000 points to inject it directly into his bloodstream."

He was watching as the system silently injected the serum into Blazren’s bloodstream without anyone noticing.

Not even Blazren himself.

"No one’s going to question anything."

"The energy will just feel like his own flames getting stronger."

Zain tilted his head as he spoke softly.

"Back then, you told me once."

"You wished you had awakened a Class. That you were tired of being stuck at your limit."

He grinned wider.

"Consider this my little gift, old man. A promotion bonus from your favorite ’hero.’"

Down below, Blazren suddenly stumbled, then dropped to one knee.

His hand hit the ground. Flames sparked wildly from his shoulders, uncontrolled.

His eyes went wide. He clutched his chest, breathing hard.

Zain watched closely.

"Good. You’re feeling it, aren’t you? That change. That power crawling through your bones."

"I wonder what kind of class you’ll get."

"You’ve been using fire all your life... Let’s see what the system turns that into."

Zain stepped forward, boots scraping the rooftop.

"Scavratt is right in front of you. He’s brutal, ugly, and pissed off."

"The perfect punching bag to test your new class."

Below, the rusted ratman was laughing, pointing at the struggling Blazren.

"You done, old man? Where’s all that fire now?"

"Come on, I thought you were the Flame Leader of this zone!"

Zain smiled, tapping his knuckle lightly on a rooftop pipe beside him.

"Not for long."

He locked his eyes on Blazren again.

"Come on, show me. What kind of beast did the system make you?"
