This F-Rank Bubble Mage Is Too OP!

"Where is he?" Nolan muttered, a deep frown etched across his face as he scanned the area around him.

The sparse trees and rocky terrain had vanished, replaced by a dense, clinging fog that seemed to stretch endlessly in all directions. The mist dampened sound, dulled colors, and made it hard to gauge distance. It was like walking inside a dream—or a trap.

Surrounding him were the five women of his harem, their expressions tense as they huddled close to him, their bodies brushing against his. They had hired him to be their Guide, but now it was clear who was guiding whom. They clung to him not just for protection, but for direction—Nolan's presence was the only thing that felt solid in this world of mist.

After their most recent… indulgence, they'd resumed walking without any clear direction. Nolan hadn't stopped, even when some of the women began to hesitate. Complaints rose briefly, but none of them dared to stray too far from him. Whether it was fear of being left behind or simply the magnetism of his presence, they stuck close, their soft bodies pressing into his arms and shoulders as they moved.

Nolan, however, wasn't in the mood to enjoy their affection. His golden eyes were sharp with focus. For some reason, deep in his gut, he knew the biker boy was nearby. He couldn't explain it, but his instincts—which had never failed him before—were screaming that they were getting close.

"We better make sure to teach that guy a lesson!" Rachel, the blonde, snapped, her brows furrowed in frustration. She didn't bother hiding the irritation in her voice.

"Yeah! This place is creepy. He should pay for making us chase him all the way here!" another chimed in, hugging herself as she looked around nervously.

"He ruined our mood, after all that effort," a third muttered with a scowl. "He can't just run from us and expect nothing to happen."

Their voices echoed faintly in the mist, as if the fog was trying to swallow their anger.

Not long ago, their interest in River—the so-called biker boy—was twisted with curiosity and desire. But now, after exhausting their energy and pent-up aggression on the Smokey Wolves, that desire had cooled. What remained was a raw, bitter frustration. A need to regain control. To chase down the one person who defied them.

Their fixation turned darker, a thirst for revenge wrapped in the pretense of justice.

Nolan didn't say anything at first. His gaze was focused on the shifting fog ahead..

The fog whispered. The silence pressed in. He could sense Mana pathways stretching out from the distance, a strange familiarity creeping into his heart. Judging by the way the Mana was being disturbed, a possibility stirred in his mind.

"He's here," Nolan murmured under his breath, more to himself than anyone else. His eyes gleamed, excitement flickering within them. "I can feel it."

The women fell silent at his tone, instinctively sensing the shift in atmosphere.

Then Nolan stepped forward, the fog parting slightly with each stride.

"Let's go," he said. "We're close."

This time, no one dared to complain.

Nolan's gut told him something thrilling waited ahead. Maybe it was that guy… or something else entirely.

No sane person would willingly venture this far—the very edge of a dungeon, where the fog thickens, and even monsters hesitate to approach.

But that biker boy did.

Nolan's sharp gaze swept across the mist-choked terrain, his thoughts racing. The signs were here—the disturbed foliage, faint residual mana, subtle pressure in the air—and his gut never lied.

But why?

This place wasn't just deserted. It was dead. Still. Smothered in a fog so dense it muted the world itself. There were no creatures, no traps, no loot. Just an endless shroud.

Unless…

"Unless there's something here," Nolan murmured, eyes narrowing.

Something hidden. Something only he knew.

The thought made his blood simmer. Maybe that was the real reason his interest in the biker boy never wavered. From the start, it wasn't just about dominance, or revenge, or pride.

It was about intuition.

That guy is hiding something.

And now, finally, the fog was about to give up its secret.

They walked for a few more minutes when, suddenly, gasps erupted from behind him.

"What… is this even possible?!"

"Is this… real?"

"My god, this is my first time seeing anything like this…"

Rachel stepped forward, clutching Nolan's arm tightly. Her eyes, wide with awe, sparkled with excitement.

"Isn't this what they call—" she stopped, breath catching in her throat.

"A portal within a portal," Nolan finished for her, his voice calm but tight with tension. "A hidden Quest."

The fog thinned just enough to reveal it in full: a circular gate, over two meters tall, etched with ancient runes glowing faintly beneath its rim. Its edges swirled with a soft blue smoke, rotating in a slow, deliberate clockwise motion. The center was a pitch-black void, like the eye of something ancient and unknowable—pulling them toward it.

A chill ran through the group. But Nolan took a step forward, drawn in not by fear, but by the irresistible pull of the unknown.

"To think that this F-Rank Awakening Ceremony Dungeon was hiding something like this…" he muttered, a smirk tugging at the corner of his lips. "Seems like our biker boy knows a lot more than he's letting on."

Behind him, the women murmured in amazement and confusion. They could barely comprehend what they were seeing.

Nolan's golden eyes locked onto the swirling void.

"This isn't just a fluke. He came here on purpose. Which means—he's probably inside."

His smirk deepened.

"Well then… let's see if we can enter."

Hopefully, he's still alive.

He stepped closer to the portal, the fog whispering around him like a curtain drawing back.

"Don't fall behind," he called out to his harem, not bothering to look back. "We're not letting that guy out of our sights again."

One by one, the five women followed, uncertain but driven by his confidence—and curiosity.

Rachel walked ahead, her curiosity getting the better of her. She reached out to touch the swirling portal, fingers just inches from the blue mist that shimmered at its edge.

But before she could make contact, a red interface abruptly materialized in front of her.

[Access Denied. Candidate Currently Inside. Please Wait Until Trial Completion.]

The glowing letters hovered in the air, unmoving and final.

"What the hell?" Rachel frowned, pulling her hand back. "We can't enter?"

The others stepped forward one by one, each attempting to reach out—only to be met by the same crimson warning.

"Is this guy serious?" one of them muttered, folding her arms.

Another clicked her tongue. "How long has it even been? What is he doing in there?"

Nolan's expression darkened, eyes fixed on the interface.

So he was right. The biker boy was inside. And not just that—he was still alive, still progressing.

The thought stirred something inside him. Annoyance, yes, but also a growing interest. This wasn't just some F-Rank nobody. He'd already slipped past them once. Now he was inside a hidden quest even they couldn't access.

"Tch," Nolan clicked his tongue and took a step back. "Looks like we wait."

His voice was sharp, his patience thin, but he didn't take his eyes off the portal. The women exchanged glances but obediently settled in around him, forming a loose semicircle near the gate.

"I don't like this," one of them muttered.

"No one asked you to," Nolan said, voice cold. "If he's strong enough to get this far even though he's just a normal human, then when he comes out—he'll be even stronger."

A smirk tugged at his lips.

"All the more reason to be here when he does."

The wind whispered through the fog again, and the portal pulsed once with a deep, slow thrum—like a heartbeat from another world.

They waited in silence, eyes locked on the swirling void.
