The academy no longer felt like a school.
It felt like a pressure chamber.
After the second field mission in Zone B-4, the atmosphere around Kael shifted again—subtle, but undeniable. Fewer dismissive glances. More calculating ones. Conversations quieted when he approached. Not out of fear.
Out of reassessment.
He was no longer "the defective noble."
He was becoming an unknown variable.
And unknown variables disturbed structured systems.
Morning assembly was called unexpectedly.
All first- and second-year students gathered in the main arena. The stone platform at the center glowed faintly as the academy's crest activated overhead.
Instructor Mareth stood with several senior instructors, including Selene.
"The western border is destabilizing," Mareth announced.
A murmur rippled through the crowd.
"Monster migration patterns have shifted. Corrupted entities are appearing in lower-density zones."
Kael felt the Hollow stir at the word corrupted.
Selene stepped forward.
"This is not random. Something is driving them."
Silence fell.
Driving them.
That meant intelligence.
Or influence.
Either way, it meant escalation.
"Until further notice," Mareth continued, "all field missions will be conducted in mixed-year units under direct supervision."
Leon's eyes flickered briefly toward Kael.
Mixed units meant stronger students together.
Fewer weaknesses.
Fewer easy targets.
Kael kept his expression neutral.
Inside, calculations adjusted.
More supervision meant fewer chances for uncontrolled extraction.
But it also meant exposure to stronger prey.
The Hollow pulsed once.
Anticipation.
Later that afternoon, Kael was summoned again—not to the council chamber, but to the training annex reserved for advanced evaluation.
Leon was already there.
So were two other second-years.
Mareth stood in the center.
"This is a controlled stress test," Mareth said. "You four will engage in rotational combat against a stabilized corrupted construct."
The ground shifted.
From beneath the arena, a large humanoid figure rose—stitched from hardened bark and infused with swirling crimson energy.
Not alive.
Not entirely artificial.
A training construct enhanced with corrupted fragments.
Kael's senses flared.
The corrupted signature was clean.
Contained.
But active.
"Begin," Mareth ordered.
Leon moved first—fast, precise, golden aura blazing. He struck the construct's shoulder joint, forcing it back.
The second-years followed, coordinating strikes with practiced rhythm.
Kael observed for three seconds.
Flow patterns.
Weak points.
Energy distribution.
Then he joined.
He didn't rush.
Didn't overextend.
He reinforced his body minimally and targeted structural fractures.
The construct swung.
Kael ducked under the arm and struck its exposed rib seam.
The corrupted energy flared.
The Hollow reacted sharply.
Not violently.
Just aware.
The construct staggered.
Leon capitalized, driving his blade into the core node.
The figure convulsed but did not fall.
It adapted.
The corrupted energy shifted pathways.
Mareth watched closely.
"Adjust!" he barked.
Kael saw it then.
The construct's core wasn't fixed.
It rotated.
Relocated every few seconds.
Adaptive corruption.
Interesting.
Dangerous.
Kael allowed the Hollow to activate at minimal output—not to absorb, but to analyze.
The corrupted fragment within him resonated faintly.
And suddenly, the pattern became clear.
The energy rotated clockwise.
Predictable.
Kael moved before the others understood.
He feinted left, then drove his palm into the construct's lower torso precisely as the core shifted there.
The impact wasn't explosive.
But it was exact.
Leon's blade followed immediately.
This time, the core shattered.
The construct collapsed.
Silence.
Mareth stepped forward, examining the remains.
"Who identified the rotation?" he asked.
Leon glanced at Kael.
"…He did."
Mareth looked at Kael carefully.
"You sensed the corruption flow."
Kael answered calmly.
"I noticed repetition."
Not a lie.
Just incomplete.
Mareth nodded slowly.
"Interesting."
That night, Kael couldn't ignore it anymore.
The corrupted fragment wasn't just integrated.
It was synchronizing.
When he activated the Hollow near corruption, resonance occurred naturally.
Not extraction.
Alignment.
He sat cross-legged in his room, eyes closed.
"Show me," he murmured.
The Hollow responded.
Within his perception, the internal structure shifted.
New pathways formed—designed specifically to process unstable energy.
Adaptation wasn't random.
It was specialized.
The more types of energy he absorbed, the broader his processing architecture became.
That realization sent a quiet chill down his spine.
If he absorbed elemental energy—he would gain affinity.
If he absorbed bloodline traits—he would gain characteristics.
If he absorbed higher-tier cores…
He would evolve beyond human limitations.
The Hollow wasn't just growth.
It was convergence.
And convergence led to singularity.
Kael opened his eyes slowly.
"This is how monsters are born."
Not the creatures in the forest.
Something worse.
Something that consumed diversity until only itself remained.
He exhaled.
Then imposed another restriction.
No full-core absorption without lethal necessity.
Corruption fragments only if externally unstable.
No targeting allies.
The Hollow resisted longer this time.
It did not like limitations.
But it obeyed.
For now.
The next field deployment came sooner than expected.
An emergency signal from Zone B-2.
A scouting team had gone silent.
Kael's unit was mobilized immediately.
Mixed-year.
High alert.
The forest felt wrong from the moment they entered.
Too quiet.
No ambient creatures.
No natural mana flow.
Only a dense, oppressive pressure.
They found the scouting team quickly.
Or what remained of them.
Three students unconscious.
One dead.
No visible wounds.
Just empty.
Drained.
Kael's heartbeat slowed.
This wasn't his doing.
The Hollow pulsed uneasily.
Not hunger.
Recognition.
Leon whispered, "What could do this?"
Mareth's jaw tightened.
"Something advanced."
A branch snapped behind them.
They turned.
From the shadows stepped a figure unlike any beast they'd seen.
Humanoid.
Tall.
Skin marbled with dark veins.
Eyes glowing faint red.
Not fully corrupted.
Not fully human.
It smiled.
And Kael felt it immediately.
Its aura wasn't natural.
It wasn't corrupted mana either.
It was… hollowed.
Like something had carved space inside it.
The creature tilted its head.
"You smell… similar."
Kael's blood ran cold.
The Hollow reacted violently.
Not in hunger.
In alarm.
This thing wasn't prey.
It was competition.
The creature stepped forward.
And for the first time since reincarnating…
Kael felt genuine fear.
Because whatever stood in front of him…
Had been built the same way.
