My Supernatural Girlfriends Spoils Me Rotten

The world twisted the moment he crossed the threshold of flesh and fang.

Light vanished

But even without seeing, he could tell that this place was colossal.

He could unleash his strongest and biggest spell, the kind that lit up battlefields and cracked asteroid crusts… and it would've flickered here like a spark.

Power meant nothing in a place this vast.

So instead of trying to fight the darkness, he changed tactics.

He muttered a quiet incantation under his breath, weaving it tight and low. No flare. No light. Just a change in perception.

A ripple moved through him.

Suddenly, the world returned—not to his eyes, but to every nerve in his body.

The air pressed in different rhythms. The walls hummed with faint vibrations. He felt space itself breathing, pulsing.

Like a bat mapping the world in echoes, he saw with sensation.

SWOOOOSH!

He pressed forward.

Then, faintly at first, a glow appeared in the distance—a pale light cutting through the thick darkness.

Curiosity prickled at him. 'Where was that coming from?'

As he drew closer, the glow grew brighter, warmer.

And then the tunnel opened up.

Before him stretched a vast cavern the size of a planet.

Jagged, green crystals jutted from every surface, pulsing with luminescence.

Some were towering like mountains, their sharp edges casting shimmering reflections that danced across the walls.

But what made the scene even more surreal was the ecosystem thriving within it.

Creatures of all shapes moved around him—crawling on the crystalline ground, fluttering through the glowing air.

They pulsed with the same green light as the crystals, their translucent skin revealing veins of radiant energy flowing beneath the surface.

Some looked like insects, others like strange, twisted beasts—none of them anything he had seen before.

'Did they… evolve in this environment?' he whispered, eyes scanning the glowing creatures.

(Brat, don't go attracting attention. These things are volatile—kill one, and it's like setting off a series of bombs)

Pantheon's voice echoed in his mind.

He nodded, silently agreeing. Just looking at the creatures gave him the same uneasy feeling—they seemed like walking explosives, like those spawns Seris had warned about.

And if anything, these were even more unpredictable.

For now, they hadn't sensed him. He needed to take full advantage of that silence.

Move fast, stay hidden, and strike only if absolutely necessary. Every second counted.

SWOOOOSH!

He propelled himself forward.

Flying gave him freedom—and speed—but it also meant every sudden move risked drawing unwanted attention so he maintained a stable speed.

Ahead loomed a towering mountain of green crystal.

Drawn by curiosity, he dipped lower, gliding closer until he could reach out and touch it.

His fingers brushed the smooth, cold surface.

He focused, tapping into his senses to identify its elemental nature.

A subtle pulse vibrated beneath his skin.

'What kind of energy is this? Never felt anything like it before...'

(That's Aether)

"You know about it?"

(Yeah, but it's useless to study. Aether's exclusive to creatures like the Astral Beast. From what I remember, no one's ever managed to tame it. At least not and lived to tell the tale.)

"You've been gone for ages," Asher reached toward a jagged shard glowing at the base. "Things change. Maybe someone has figured it out."

His fingers hovered over the crystal. "I'll take one. Study it later. Could be another path to power."

(Brat—wait!) Pantheon's voice snapped like a whip.

(Aether can't be stored in a space bag. It's the very thing letting the Astral Beast lock space. You try to contain it, and you'll blow a hole in your space bag—or yourself.)

Hefroze mid-reach, fingers inches from the glowing shard.

"Right. Noted." He pulled back slowly, brow furrowing. "Guess I'll leave the glowing rock alone."

(Yes. That's the smartest decision you've made all day,)

Asher shook his head, pushing the thought aside.

But out of nowhere.

The entire place began to tremble.

A deep, guttural vibration rippled through the air, followed by a low rumble that seemed to come from every direction at once.

Glowing creatures around him paused mid-motion, twitching as if they, too, felt the shift.

The walls pulsed, and the ground cracked beneath a towering crystal mountain.

"What's happening?" Asher muttered, his eyes narrowing as he looked up. "Why do I feel vibrations… from the surface?"

(Brat…) Pantheon's tone grew serious. (That's not normal. Something just pissed this thing off—for real this time.)

Asher gritted his teeth. "What the hell did they do up there?"

The green crystals began to hum.

And they lit up—one by one—like a chain reaction across the massive chamber.

Their glow pulsed brighter and brighter, intensifying until the entire cavern bathed in emerald radiance.

His heart drummed. Every nerve screamed danger.

"Damn it!"

He snapped his hands forward, and magic exploded around him.

The first barrier surged into existence—a standard kinetic shield, silver and firm, wrapping tight against his skin.

He didn't stop.

The moment the first one clicked into place, he layered another on top—a magical filtration ward, filtering out unknown energies that might seep through.

The crystals crackled with power.

He stacked a third—a temperature-buffering dome, reinforcing his inner space to resist scorching heat.

Asher didn't stop.

Couldn't stop.

He knew that if the green energy pierced even a sliver of his defenses, it wouldn't just burn him.

It would creep and burrowed past muscle and mana channels, slithering straight into his core.

And once it reached there?

He wouldn't bleed or break. He would detonate like an overcharged bulb.

CRACK!

A layer got destroyed.

It held for two seconds. Maybe three.

Then—CRACK!—Another shattered like thin ice under a war hammer, shards of translucent energy scattering into the air.

Asher didn't pause.

He immediately replaced it with another.

'Rebuild. Reinforce. React.' He chanted under his breath, like a mantra keeping him sane.

Another pulse of green aether surged toward him. This one was faster, hotter, heavier.

The air around him had turned syrup-thick, his barrier dragged down by gravity he couldn't see.

He managed to stay afloat, but every second drained him.

'Why did I say yes to this?'

It was too late for regret now.

Gritting his teeth, he kept weaving barrier after barrier, each one shrinking his safe space, like a fortress closing in around him.

The walls grew thinner, the energy drained faster, but still he held on—desperate to buy even a few seconds.

Then, suddenly—

The green light vanished.

Asher hovered there, chest heaving, drenched in sweat, every nerve on edge—wondering if it was over.

(Brat, don't waste time. Fly straight deeper—we need to get out of this area.)

"I think we should retreat!"

(No. Go forward!)

He hesitated for a moment, unsure.

But in the end, he moved forward,

The creatures remained frozen in stasis, their condition giving him the precious margin he needed.

Even drained to the bone, he kept going, fueled by sheer willpower.

Finally, he reached a new section—swallowed in near-total darkness.

THUD!

Landing awkwardly on the soft, pulsing muscle beneath him, he let himself collapse, every ounce of strength draining away as he lay there, utterly exhausted.

Still, he didn't forget to cast a barrier to hide his presence while he rested and recovered his strength.

(Brat, you can use your space storage now. Take some of the dragon cores you stored earlier and absorb them.)

"Okay,"

He focused, feeling the cores' energy flow into his body. Quickly, his strength began to return, the exhaustion easing from his limbs.

This was another function of the cores that Pantheon taught him—storing energy beforehand so he could instantly regain his power when needed.

Usually, this kind of tactic was risky and harmful to the body, often causing serious permanent damage.

But because he got a perfect magical body, fused with his dragon body, he became something else entirely—a being able to withstand and channel extreme energy flows without breaking.

Though that didn't mean he could handle every kind of energy. That's why he never dared absorb Aether. Instinctively, he knew it wasn't meant for him.

Trying to take it in would be like swallowing poison.

With his power restored, he pushed himself up and took to the air again, flying deeper into the beast's dark, vast interior.

He still felt faint vibrations from the surface now and then—clear signs that things up there weren't going well.

Soon, a slow, thudding echoed ahead—like the steady beat of a giant heart.

"This has to be the circulatory system," Asher muttered, eyes narrowing.

He floated forward, careful to keep his barriers active.

The walls here oozed a viscous, oily fluid that hissed when it touched his barrier.

Ahead, a massive artery stretched like a dark tunnel. he could almost feel the blood—thick, hot, and full of strange energy—rushing past.

He steeled himself. This wasn't just a monster's gut anymore. He was diving straight into the beating heart of the Astral Beast.

(Brat, that Genesis Crystal has to be close. I can feel something ahead. Get your guard up—and link those dragon cores. Just in case the space locks down again.)

"Got it," Without question, he reached deep within and clamped the cores in his robe.

Once his preparations were locked in, he moved closer to the heart.

But the moment he crossed , the pressure hit him—hard.

It wasn't just physical weight pressing down; it clawed at his mind, a force that whispered doubt, fear, and madness all at once.

'No. Focus.' He clenched his jaw, teeth grinding. 'Can't let it get to my head.'

"Asher... Asher..."

He was stunned. The voice was hers. Index.

And she sounded like she was in pain.

Images began forming in his mind.

Her face, pale and tear-streaked, trapped inside an endless void, reaching out, waiting.

"Why? Why did you leave me alone?" Her voice cracked, tears and blood mixing as they overflowed from her eyes.
