This F-Rank Bubble Mage Is Too OP!-Chapter 95: To Another City

The underground train station of Voulton City hummed with the quiet energy of advanced mana-tech, its crystalline walls pulsing with soft blue veins of light that guided passengers through the sprawling terminal. Unlike the ancient rail systems of the old world, these trains didn't run on metal tracks—instead, they levitated along specialized mana conductors that stretched through underground tunnels, connecting city to city beneath the transformed earth. The magnetic field generators created a gentle thrumming that resonated through the platform, a sound that had become as familiar as breathing to the citizens of this new world.

Hunters and civilians alike moved through the terminal with practiced efficiency, their conversations mixing with the ambient hum of departure announcements echoing from floating holographic displays. Some wore the standard gear of their professions—reinforced clothing for dungeon diving, formal attire for guild meetings, or the casual wear of those simply traveling between safe zones. The air carried the faint scent of ozone from the mana-powered systems and the distant aroma of street food from vendors positioned near the platform edges.

"Someone snuck into Melody's private lounge this morning… I wonder who could it be," Freya said before putting a lollipop in her mouth and staring directly at River, who stood beside her with studied nonchalance.

Gone was her usual crisp white blouse. Instead, she wore a dark tactical jacket that hung loosely over equally baggy pants, the kind of outfit that seemed designed for both comfort and concealment. But River's trained eye caught the telltale signs of what lay beneath—her personal battlesuit, its advanced fabric barely visible at her collar and wrists. Faint threads of mana coursed through the hidden garment like liquid starlight, particularly noticeable along her neck where the suit's neural interface connected with her nervous system. The soft glow pulsed in rhythm with her heartbeat, a reminder that even in casual conversation, Freya was always ready for combat.

River himself had abandoned his usual simple attire for a formal black suit, the kind worn by professional Hunters preparing for higher-rank dungeon expeditions. The tailored fabric moved with him naturally, designed to allow for combat mobility while maintaining an appearance of sophistication. As promised, Freya was taking him to another city where they would attempt a C-Rank dungeon together—a significant step up from his usual solo clearing of lower-ranked portals.

"So?" River glanced at her, raising an eyebrow as if he couldn't care less about the news she'd just shared. His voice carried just the right note of casual indifference, though internally he was already calculating how much Freya actually knew.

Platform 7 stretched out before them, where passengers waited for the next departure to Cairn City. The massive viewing windows offered glimpses of the tunnel mouth—a perfect circle carved through solid rock, lined with mana conductors that glowed like earthbound constellations. In the distance, the faint rumble of an approaching train grew stronger, the magnetic field creating small distortions in the air that made the tunnel entrance shimmer like a mirage.

"Well, she left the city after that encounter," Freya said playfully, rolling the lollipop from one side of her mouth to the other, her eyes squinting at River with obvious amusement. "I wonder who this mysterious intruder could have been, though. Someone skilled enough to bypass building security, reach her private lounge undetected, and somehow convince a terrified celebrity to pack up and leave town within hours." Her tone was light, conversational, but each word was carefully chosen, like a hunter setting snares.

She definitely knew what was happening, River thought, suppressing a sigh. There was no point in underestimating Freya's intelligence network. The woman had connections throughout the city, and very little happened in Voulton's Hunter community without her knowledge.

"We don't have to talk about that, you know," River said, trying to redirect the conversation away from dangerous territory. He adjusted his suit jacket with deliberate casualness, straightening the collar as if the topic was merely a minor distraction. "Some things are better left as mysteries."

Around them, the terminal continued its steady flow of activity. A group of young Hunters passed by, their excited chatter about their first C-rank dungeon assignment carrying over the ambient noise. An elderly couple sat on one of the floating benches, the woman's healing-class aura providing a soft green glow as she tended to her husband's arthritis. Near the platform edge, a Modern Class Hunter, a Technomancer was making adjustments to his mana-enhanced tablet, the device's screen flickering with incomprehensible data streams.

The approaching train's magnetic field grew stronger, causing small metallic objects throughout the station to vibrate softly. River could feel it in his bones—that peculiar sensation of standing near powerful mana-tech systems, like static electricity building before a storm.

Freya pulled the lollipop from her mouth with a soft pop, her smile widening. "Oh, but I find mysteries so fascinating, don't you? Especially when they involve talented individuals with... unique skill sets." She gestured vaguely with the candy, as if painting invisible pictures in the air. "Bubble-related skill sets, perhaps?"

River's jaw tightened imperceptibly. So much for keeping things subtle.

"Okay! You got me, alright? I'm the one who did it, I'm the intruder," River admitted with a defeated sigh, his shoulders sagging as if the weight of pretense had finally become too much to bear. "Nothing can really escape you, huh."

"Isn't this the reason why you wanted my cooperation? Why you wanted me to be your partner for whatever goal you have?" Freya shrugged, the lollipop clicking against her teeth as she spoke. "Now you know the true capability of my network."

"I already knew that from the start," River said, massaging his forehead with his fingertips. "I just didn't know how infuriating it could be to be on the receiving end of it."

"Hehe," Freya chuckled, her eyes glinting with something River couldn't quite decipher—amusement mixed with something deeper, more calculating. "You still don't know its limits though."

"I'll know about them eventually," River said with quiet confidence, though whether that was a promise or a threat remained unclear.

The conversation was interrupted by a deep, resonant hum that seemed to vibrate through the very bones of the station. The magnetic train emerged from the tunnel like a sleek predator, its surface gleaming with the same crystalline technology that powered the tracks. The vehicle moved with impossible smoothness, creating barely a whisper of displaced air as it came to a perfect stop at the platform. Doors slid open with a soft hiss, revealing an interior that glowed with soft amber lighting.

"Platform 7 express to Cairn City, now boarding," the automated announcement echoed through the terminal in multiple languages, the holographic displays shifting to show departure information.

River and Freya joined the stream of passengers moving toward the train. As they stepped aboard, River caught a glimpse of a young woman with glasses standing near the platform edge—Freya's assistant, he realized, her professional demeanor unchanged as she watched them depart. She offered a slight bow as the doors sealed shut with finality, sealing them into the train's climate-controlled environment.

The acceleration was barely perceptible, a testament to the advanced mana-tech systems that powered their journey. Within moments, they were descending into the underground tunnel system, the last traces of the station's lights fading behind them as they plunged into the earth's depths. The tunnel walls rushed past their windows in a blur of reinforced concrete and glowing mana conduits, creating a hypnotic pattern of light and shadow.

The underground portion of their journey lasted nearly an hour, the train maintaining its incredible speed through tunnels carved deep beneath the transformed landscape. Occasionally, River caught glimpses of other passages branching off into the darkness—maintenance tunnels, emergency routes, or perhaps connections to other city networks that stretched across the continent like veins of civilization.

Then, as suddenly as they had descended, they began to rise.

The train emerged from the tunnel mouth like a whale breaching the surface, and suddenly they were suspended high above the ocean on a magnificent bridge of pure engineering prowess. The special railing stretched across the water for kilometers, supported by towers that rose from artificial islands scattered across the sea. The entire structure was encased in a powerful magnetic field that shimmered faintly around the train, creating a protective barrier that even B-Rank Hunters would struggle to penetrate.

It was still deep night, and the full moon hung low over the horizon, casting a silver pathway across the dark waters below. The ocean stretched endlessly in all directions, its surface broken only by the occasional whitecap or the distant lights of shipping vessels navigating the transformed world's new trade routes.

River found himself drawn to the window, his reflection ghostlike against the glass as he studied the vast expanse of water below. The moonlight painted everything in shades of silver and deep blue, creating a scene of haunting beauty that seemed at odds with the dangers lurking beneath both the waves and the world itself.

Freya watched him with undisguised interest, her earlier playfulness replaced by something more thoughtful. She had tucked the lollipop away, and now her dark eyes studied his profile with the intensity of someone trying to solve a particularly complex puzzle.

"This is the same ocean that's going to surround Voulton in a few days," Freya said quietly, her voice carrying a note of anticipation that might have been unsettling to anyone who didn't know her. "And the more I look at it, the more I want it to cover Voulton completely—wash it away to destruction."

"You are evil," River observed, settling more comfortably in his seat without taking his eyes from the moonlit water. There was no judgment in his voice, merely a statement of fact delivered with the casual tone one might use to comment on the weather.

"So you fucked evil, huh?" Freya raised an eyebrow, her lips curving into a smile that was equal parts predatory and amused.

"You initiated, I complied and cooperated," River replied with a smirk, finally turning from the window to meet her gaze directly. The moonlight streaming through the glass cast half his face in shadow, making his expression difficult to read. 𝙛𝓻𝒆𝓮𝒘𝙚𝙗𝒏𝙤𝙫𝓮𝒍.𝓬𝒐𝙢

Silence stretched between them, filled only by the gentle hum of the train's systems and the distant whisper of wind across the magnetic barriers. The ocean continued to roll beneath them, vast and mysterious, holding secrets that neither of them could fully comprehend.

Freya's expression shifted subtly, her eyes taking on a lustful gleam that seemed to reflect the moonlight streaming through the windows. "Want to do it in the bathroom?" she asked, her voice dropping to a husky whisper. "There's still a few hours before we arrive in the next city."

River considered the offer for exactly three seconds, his gaze traveling from her face to the empty corridor beyond their seats, then back to her expectant expression.

"Hmm, interesting offer," he said slowly, as if weighing the pros and cons with scientific precision. Then his own smile turned wicked. "So no... there's no way in hell I'm going to refuse."
