The sky above Eisenvald was no longer recognizable as night.
It had become a burning ceiling of smoke and collapsing light.
Somewhere beneath that sky—
Seraphina Noctrelle stood at the center of a shrinking holy barrier.
Her breath was uneven.
Not because she was injured.
But because she understood something she did not want to admit.
Outside the barrier—
Valtherion was still standing.
The Demon King's General rotated his axe slowly, as if testing its weight again.
"You are holding longer than predicted," he said calmly.
Seraphina wiped blood from the corner of her lip.
"…You talk too much for a weapon."
Valtherion's eyes narrowed slightly.
"That is incorrect."
"I am not a weapon."
A pause.
Then—
"I am the part of war that learns."
The pressure in the air deepened.
Seraphina felt it immediately.
He was adapting.
Every exchange.
Every movement.
Every defensive pattern.
He was recording her.
Not fighting her.
Studying her.
"…So that's how it is," she whispered.
Her grip tightened.
"Then I will make sure you don't finish your research."
Holy light erupted again.
---
Inside the collapsing command tower, a surviving captain shouted orders through smoke.
"Retreat the civilians to the southern tunnels!"
"The west gate is gone!"
"We've lost communication with the outer walls!"
A soldier burst into the room, armor cracked.
"Captain! The Hero is holding the center—but the monsters are adjusting around her position!"
The captain froze.
"…Adjusting?"
Another explosion shook the building.
A wyvern shadow passed over the broken window.
The soldier swallowed hard.
"They're not just invading…"
"They're coordinating."
Silence.
For the first time—
the word "army" felt too small.
---
Far above the burning battlefield—
a black silhouette cut through the clouds.
Hax was no longer walking.
No longer observing.
He was descending.
The wind tore past his armor, but nothing touched him.
[Distance to Epicenter: 12.4 km][11.9 km][11.2 km]
The system kept updating.
But something was wrong.
Hax narrowed his gaze.
The battlefield was not chaotic.
It was structured.
There were layers of mana control.
Frontline pressure. Rear reinforcement. Aerial dominance.
"…Military formation," he murmured.
Not monsters.
An army.
That was the difference.
And then—
the system flickered.
[WARNING][Secondary High-Grade Entity Detected]
Hax paused mid-air.
Another one.
Something else.
"…So there's more than one commander."
For the first time—
interest sharpened in his voice.
---
Far behind the demon army lines—
a massive figure stood atop a ruined fortress.
Clad in layered black armor engraved with ancient sigils.
Not a soldier.
Not a beast.
A strategist.
Beside him floated a warped crystal showing battlefield projections in real time.
Valtherion's position.
Seraphina's barrier.
Civilian collapse rates.
Mana density spread.
Everything.
He tapped the crystal once.
"…Interesting."
His voice was calm.
Not excited.
Not angry.
Curious.
"The Hero is stronger than expected."
A pause.
"But not enough."
He turned his gaze northward.
As if sensing something beyond the battlefield.
"…And something else is approaching."
The air around him distorted slightly.
Space itself felt heavier.
Then—
he smiled faintly.
"Good."
"Let it come."
---
Back in the burning city—
Seraphina's blade clashed again.
But something changed.
Valtherion did not block.
He stepped into the strike.
Holy blade cut across his armor—
but instead of retreating—
he grabbed her wrist.
Seraphina's eyes widened slightly.
Valtherion's voice lowered.
"I understand you now."
A beat.
"You are not the strongest Hero."
"You are the most stable one."
Seraphina tried to pull back—
but the pressure intensified.
Valtherion released her suddenly and stepped away.
"…So the report was correct."
"You are still incomplete."
Seraphina narrowed her eyes.
"What are you talking about?"
But Valtherion only raised his axe again.
"This battlefield is no longer enough."
Then—
he struck the ground.
Not toward her.
Not toward the city.
But upward.
"Axe Skill: Rift Sever."
A crack opened in the air.
Space itself distorted.
Seraphina's expression changed instantly.
"…A spatial gate?!"
Valtherion stepped back.
And for the first time—
he looked upward.
Not at her.
Not at the city.
But at something far beyond.
"…Arrive faster, My Lord."
Then—
he disappeared into the rift.
Silence.
The battlefield froze for a moment.
Then chaos followed.
"Retreating?!"
"He withdrew?!"
"Why now?!"
Seraphina stood still, breathing heavily.
Her barrier faded.
The holy light dimmed.
She stared at the place where Valtherion vanished.
"…He wasn't defeated," she whispered.
"He left."
That realization was worse than victory.
Because it meant—
this was not the end of anything.
Only a probe.
A test.
A measurement.
[7] Hax — Final Approach
High above—
Hax saw it.
The spatial distortion.
The tear in reality.
"…So they can open gates."
His gaze sharpened.
Not surprised.
Not alarmed.
Just calculating.
[New Variable Confirmed][Enemy System: Multi-Commander Structure]
Hax exhaled slowly.
"This is not a raid."
"It's an operation."
Then—
his speed increased.
The sky cracked under his acceleration.
Clouds parted violently.
Mana condensed around him like collapsing gravity.
And he spoke softly—
not to anyone.
"To think I would see something structured enough to challenge my design…"
A pause.
"…Interesting."
Then—
He descended toward war.
And at that moment—
the world below him did not realize that something far more dangerous than an invasion was already moving.
Moments after Valtherion vanished,
Seraphina's holy barrier completely collapsed.
Not because it was destroyed.
But because it was no longer needed.
The surrounding monsters around the city paused for a brief moment.
As if they had sensed something.
Then—
they began to retreat.
One by one.
No visible command.
No panic.
No chaos.
Like a tide suddenly pulling back into the sea.
"…They stopped?" a soldier's voice trembled.
"That's not a retreat… that's…" the captain stared blankly, "a phase shift?"
Seraphina stood amid the ruins.
Her eyes narrowed.
This was wrong.
An invasion of this scale does not stop just because a commander disappears.
Unless—
something else had replaced control.
The wind above Eisenvald changed.
Not merely in direction.
But in pressure.
As if the sky itself was restraining something that was approaching.
Seraphina looked up.
"…What is this now?"
The previously burning sky began to fracture visually—not literally, but as if the perception of space itself was being disrupted.
The mana in the surrounding area trembled.
Not chaotically.
But drawn toward a single point.
Like gravity.
And all the monsters that had just retreated—
stopped completely.
Then slowly—
they turned their heads in the same direction.
Toward the northern sky.
High above that sky—
Hax pierced through the final layer of clouds.
His system no longer displayed distance.
Only a single blinking message remained:
[ENTERING WAR DOMAIN]
The air beneath him felt heavy.
Not because of mana pressure alone—
but because the entire battlefield was still "alive."
The structure had not collapsed.
It was still running.
Still operating.
Hax lowered his gaze.
Eisenvald lay below like a burning wound.
Fire, smoke, and the silhouettes of creatures still moved between the ruins.
He did not stop.
He descended.
---
A shadow fell from the sky.
Not a large scale magic.
But a single figure.
DENT—
The ground cracked slightly as Hax landed on the roof of a half-collapsed building.
No explosion.
No light.
Only a small pressure that slowly lifted the surrounding dust.
Several nearby monsters paused.
They did not immediately attack.
Their instincts caught something different.
Something that did not belong in this battlefield.
Hax did not look at them.
He stepped down from the roof.
Toward the main street filled with rubble.
-
On the other side of the city—
Seraphina stood among the ruins, her breath heavy.
The holy barrier from before was already gone.
Her mana was nearly depleted.
She could only rely on the remaining light in her blade.
Then she saw it.
That figure.
Black armor.
Tall.
Silent.
And a mana pressure unlike any of the monsters before.
"…A new commander?"
Seraphina's expression hardened.
Her reflexes kicked in immediately.
Her sword rose halfway.
"There's more…?"
Her voice was low.
Not angry.
But sharpened exhaustion.
"How many more did you send?"
She was already prepared.
One more strike.
It might be enough to force them to retreat.
Even if only for a few minutes.
But Hax did not look at her.
He did not even stop.
Ahead of him—
a group of monsters was destroying the last barricade protecting the remaining civilians.
Hax walked toward them.
Then—
his sword came out.
Not a greatsword.
Not a special weapon.
Just a standard adventurer's blade.
And he moved.
CLANG—
One slash.
Not spectacular.
But clean.
One monster fell.
The other two reacted instantly.
A counterattack came.
Hax slightly lowered his body.
Evaded.
His steps were small.
Efficient.
No skills.
No light effects.
Just a body moving as if already accustomed to the rhythm of war.
CLANG—CLANG—
Two more slashes.
The monsters fell.
[4] Seraphina's Shock
Seraphina went silent.
"…He's not attacking me?"
Her eyes narrowed.
Her instincts conflicted.
That armor was still suspicious.
That aura was still dangerous.
But—
that person was not targeting her at all.
He was instead—
cutting down monsters.
Saving humans.
Seraphina lowered her sword slightly.
"…What is this?"
She did not understand.
On a battlefield like this—
there was no "neutral."
--
Hax kept moving.
He did not use large-scale skills this time.
Only a sword.
And fast decisions.
One step forward.
One slash.
One opening created.
He read the battlefield like a system.
Not as chaos.
But as an optimal route.
Monsters on the left.
Safe route on the right.
Civilians behind the rubble.
Pressure point ahead.
Everything processed without sound.
Like a real-time simulation being executed.
--
Seraphina finally moved.
But not to attack.
She approached slowly.
Her sword was still raised, but not activated.
"Hey!"
Her voice was firm.
Hax did not stop.
Another monster attacked from the side.
CLANG—
One more slash.
The creature fell.
Only then—
Hax spoke.
"…If you interfere, fall back."
A flat voice.
Not aggressive.
Not defensive.
As if Seraphina was merely an irrelevant external variable.
Seraphina frowned.
"…You're not one of them?"
Hax did not answer immediately.
He cut down another monster.
Only after that—
"…No."
One word.
Seraphina fell silent.
Her grip on her sword loosened slightly.
"…Not…"
She looked at the armor again.
Not a monster's speech pattern.
Not a demon's aura.
Not the usual hostile pressure she felt.
Just—
cold.
stable.
and too controlled.
She turned her gaze toward the remaining monsters.
Then back to Hax.
"…Then why are you here?"
Hax finally came to a slight stop.His sword was still dripping with monster blood.
He turned his head slightly.Not toward Seraphina.But toward the city still burning behind them.
A brief silence.
Then he spoke."…I was sent."
Seraphina frowned slightly."Sent?"
Hax continued, flatly."…From another kingdom."
He shifted his sword a little, flicking off the blood clinging to it.
"…To gather information."
Seraphina did not answer immediately.Her eyes narrowed.
"…Information about what?"
Hax looked at the ruined city a moment longer before replying.
"…Rumors."
A brief pause.
"…The emergence of the Demon King."
Seraphina stood still.
For the first time since the war had begun—she did not know who she was supposed to be wary of.
The enemy?Or this man?
In the distance—the remaining monsters slowly began to withdraw from the area Hax had cleared.
As if the battlefield itself was being "reset" around his presence.
