Mystic Calling：Stone of Glory-Chapter 879: They Picked the Wrong Sky

Ethan snapped his head up.

High above, a figure in heavy armor hovered in the sky, radiating a twisted, domineering energy.

The moment he appeared, the surrounding natural energy surged toward him like it had found its true master—rushing in from every direction, flooding into his body.

Hummm.

Hummmm.

HUMMMMM.

The resonance built layer by layer, each pulse heavier than the last.

Within seconds, a massive energy sphere condensed in the man's palm, crackling with raw, unstable power.

He glanced around, a smirk tugging at his lips—openly mocking.

"Didn't expect the energy here to be this rich."

He let out a low, dismissive chuckle.

"This must be that so-called Phoenix Empire, huh?"

"Pretty damn remote. Can't believe I wasted my time coming all the way out here."

He raised his hand.

"Well then…"

"Let's start with a little lesson."

Without hesitation, he hurled the energy sphere downward.

The moment it left his hand, the air turned suffocating.

The sheer destructive force packed into that orb bore down like a falling star. If it hit—

The consequences would be catastrophic.

…

Ethan didn't have time to think.

The instant that energy sphere began its descent, he knew—

If it landed, the entire defensive line of Emerald Castle would be torn wide open.

His body blurred.

In the blink of an eye, he was in the sky.

The core of his Powered Combat Armor roared to life, channeling a torrent of power through the intricate energy circuits etched across its surface.

BOOM—!

BOOM-BOOM—!

Blinding energy compressed in his palm, shaping itself into a razor-sharp disc that shimmered with lethal intensity—an Energy Disc so dense it seemed to slice the very air around it.

Without pause, Ethan hurled it upward.

The silver arc streaked through the sky like a blade drawn across the heavens, slamming head-on into the falling energy sphere.

BOOOOM—!!!

The collision detonated midair.

A deafening shockwave ripped through the sky, space itself fracturing like shattered glass. The boundary between earth and sky blurred, warped by the sheer force of the impact.

Ethan held his position, floating in the chaotic swirl of energy fallout.

But inside, his mind was reeling.

That attack—just a casual throw from the armored man—

Had forced him to burn nearly all his power just to stop it.

"Who the hell is this guy…"

Ethan's eyes locked onto the armored figure above.

The strength he'd just displayed was far beyond what any standard high-tier legion soldier should be capable of.

And this… was only the beginning.

A low rumble echoed across the sky.

Then the heavens split open.

Hundreds of figures emerged in rapid succession, each clad in identical armor, their auras synchronized—wild, cold, and oppressive.

But what made Ethan's heart sink wasn't just their numbers.

It was their energy.

They weren't fighting as individuals.

They were linked.

Sharing power.

Moving as one.

Ethan immediately dropped back a step, energy flaring in his hands as he summoned a massive Energy Greatsword, its blade humming with condensed force.

At the same time, Emerald Castle's main forces launched into the sky.

The Sky Fortress formations deployed across the upper atmosphere, locking into full combat posture.

The battle was about to begin.

Just then—

From within the enemy formation, a soldier in lighter armor stepped up beside the commanding officer, lowering his voice.

"General… something's wrong."

"The spatial coordinates… they don't match."

The general's brow furrowed hard.

"What do you mean?"

"This… doesn't seem to be the Phoenix Empire."

The moment those words left his mouth, the air around them seemed to freeze.

The general's expression darkened instantly.

Without hesitation, he pulled a 3D starfield map from his personal storage and began cross-referencing the coordinates.

A few seconds later—

His face turned pitch black.

"Goddamn it."

"We hit the wrong target."

This place was, in fact, nothing more than a low-tier, backwater Plane World.

The general's fury practically leaked from the seams of his armor.

"Why the hell didn't you say something sooner?!"

"You wait until after we've launched an attack to tell me the coordinates are off?!"

He looked like he was about to tear the soldier apart on the spot.

But the next second, his gaze snapped forward again.

Too late now.

Retreat wasn't an option.

"We've already made our move," he said coldly.

"Might as well crush them."

"Order the entire force—maximize energy output."

"Advance."

The command dropped. 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

And war erupted.

Ethan had already fallen back into one of the Sky Fortresses.

His armor synced instantly with the fortress core, linking his consciousness to the entire defense grid. Power surged through him, flowing outward in waves.

The two forces clashed head-on in the skies above.

The enemy only numbered in the hundreds.

But the power they unleashed was terrifying.

Especially the strange energy radiating from their bodies—

Darkness. Death. Corrosion.

Layered together, it created a wide-area killing field.

Emerald Castle's soldiers began dropping fast under the onslaught.

Ethan's frown deepened.

If they didn't neutralize this force quickly—

The consequences would be devastating.

All their current defenses and reserves were meant for the coming assault from the Vorgar Empire.

If they got drained now by this unknown enemy—

Emerald Castle wouldn't survive the cost.

Ethan immediately pulled up the system's deep-scan interface, launching a full analysis of the enemy forces.

Data streamed across his vision.

Their energy signatures were saturated with Darkness and Death attributes.

But deeper in the structure—

There was something else.

A strange, alien aura he'd never seen before.

And it was spreading.

After rapidly analyzing the enemy's energy composition, Ethan finally reached a clear conclusion.

That power—cold, corrosive, steeped in death and decay—

It wasn't invincible.

"They're weak to fire."

The realization locked into place in his mind.

The most direct—and most effective—counter to this kind of energy was pure, searing flame. The kind that could burn everything down to its last atom.

Ethan took a deep breath, forcing down the chaotic energy surging through his body.

Then, without hesitation, he began channeling fire-element energy from deep within himself.

The flames surged through his armor's conduits, flowing along the neural link and pouring straight into the Sky Fortress's core.

Ultimate Annihilation Cannon—charging.

Hummmm—

A deep, dangerous resonance echoed through the fortress interior.

Then—

A massive beam of light tore into the sky.

The moment it reached altitude, the compressed energy detonated outward. A flood of blistering flame cascaded down from the heavens like a wrathful god had opened the gates of the sun.

Wherever the fire touched, the eerie, death-laced energy that had blanketed the battlefield reacted instantly—like it had met its natural predator.

It ignited.

It crumbled.

It vanished.

It worked.
