Today, the lecture hall felt different.
Not just because it was full, but because everyone was here.
All departments. All years. Combat Division. Healing Arts. Sword Division. Rare Magic. Summoning Division and much, much more.
Even the usually detached Alchemy Division had been summoned.
Mandatory attendance.
When that word circulates through an Academy like ours, it never means anything trivial.
I took my seat beside Mei Lin, the murmur of hundreds of students pressing against the high stone ceiling.
Even the Legendary Students were present, scattered among the rows like quiet constellations.
Kean leaned back in his chair. "Since when does World Structures require the entire Academy?"
"That's what worries me," I muttered.
The doors closed.
Silence fell almost immediately.
Professor Qian stepped forward, robes immaculate as always, but there was no leisurely composure today.
No polite academic preamble.
He raised his hand.
The air above the platform shimmered.
A vast projection unfolded, a detailed map of the continent, glowing softly with flowing lines of mana currents threading across cities, forests, mountains, and borders.
Then the cracks appeared.
Thin at first.
Then branching.
Crimson fractures splitting across the projection like stress lines in glass.
A collective intake of breath swept the hall.
"These," Professor Qian said evenly, "are confirmed spatial ruptures."
The word settled heavily. Confirmed…
"In the past six months alone," he continued, "rupture activity has increased by thirty-two percent."
The map shifted. Several fractures pulsed brighter.
"Three weeks ago, a mid-scale breach formed near the eastern trade corridor.
Two days later, a rural settlement ninety kilometers away reported a coordinated attack by corrupted magical beasts."
The image changed.
It showed burned farmland, collapsed wooden structures and many different forms of destruction.
"The beasts displayed unusual cooperation patterns," he added. "Strategic flanking. Delayed engagement. Coordinated retreat."
"They were being influenced."
The word lingered.
Professor Qian let the silence stretch before speaking again.
"Lower- and mid-tier infernal entities have crossed through several of these ruptures. In previous years, such crossings were sporadic. Recently, their behavior has become… organized."
A second projection appeared.
A silhouette, humanoid,with elongated horns curling backward, eyes glowing faintly through a haze of distorted mana.
"Infernal entities do not breathe our air," he said. "They do not feed as we do. They sustain themselves through mana corruption. What enters our world is not simply a creature."
The image darkened.
A fog-like substance spread from the fracture zones, seeping along mana currents like ink in water.
"Infernal miasma."
"When ruptures form," he explained, "miasma seeps through.
It integrates into our normal mana, destabilizing its structure. Living organisms exposed to high concentrations may experience mutation, aggression spikes, or loss of cognitive restraint."
The projection shifted again,
magical beasts before and after exposure.
The difference was subtle at first.
Then horrifying.
Mana signatures once smooth and rhythmic now jagged and erratic. Eyes glowing. Veins darkened.
"They become more susceptible to external influence," he said quietly.
Mei Lin's hand tightened around her sleeve.
"And the demons," someone whispered from the back, "can control them?"
"Increased susceptibility does not equal complete control," Professor Qian replied. "However, coordination suggests higher infernal oversight."
The hall felt colder.
He gestured again.
The map zoomed out.
It pulsed faintly, fractures glowing brighter.
"More concerning," he continued, "is the rate of formation. Ruptures are appearing more frequently. Larger. Less stable."
My pulse quickened.
I forced myself to breathe evenly.
He wasn't finished.
"In addition," he said, voice steady, "there have been documented cases of human exposure."
The projection changed again.
A diagram of a human mana circuit appeared, clean, luminous pathways flowing through a body.
Then the same diagram, faintly darkened.
"In low concentrations, infernal miasma may cause mild symptoms. Irritability. Heightened aggression. Emotional instability."
A murmur spread.
"In moderate cases, subjects report intrusive impulses, distorted perception, and loss of self-regulation."
The diagram darkened further, mana currents warping.
"In severe cases, identity destabilization may occur. Individuals may no longer recognize their own behavioral patterns."
That landed heavily.
I swallowed.
"But," he added firmly, "students are not to panic."
The word echoed.
"Human mana systems possess natural purifying tendencies. When exposure is limited and identified early, the body attempts to cleanse itself.
Furthermore…Healing Magic significantly accelerates recovery."
A faint wave of relief moved through the hall.
"Most cases documented thus far have been reversible."
Most.
"As long as large-scale contamination does not occur," he clarified.
That small addition was enough to keep the tension intact.
Professor Qian clasped his hands behind his back.
The Academy has therefore implemented immediate structural changes."
The projection shifted again. I read the updates in my mind:
New schedules… increased field simulations… coordinated exercises… and more exposure with infernal mana and affected beasts.
Additionally, there will be specific training exercises for the different divisions.
For example, Alchemy will focus on understanding the miasma itself, Healing will specialize in mana purification techniques,
and all Combat Divisions will study its effects in the field. This includes observing animals that have been mutated by the miasma, learning to anticipate their unique abilities, and practicing techniques to safely contain or counteract them. More detailed instructions will be provided to them later.
The words echoed in my chest.
"If rupture frequency continues at its current rate," he added, "frontline engagement within your lifetime is statistically probable."
I tried to recall the original plot.
The ending had been sudden and I can only remember that it was a real tragedy. It was so bad, that I threw the Book around my room.
Was it because of this?
Professor Qian's gaze sharpened.
"You will face corrupted beasts."
The projection displayed a towering wolf-like creature, body partially crystallized, mana jagged and blackened.
"Some may be reversible."
The image shifted, another creature, fully warped, mana structure collapsed beyond recognition.
"Some will not."
Silence pressed against the walls.
"Engagement with irreversibly corrupted organisms will be considered lethal containment."
The weight of that word settled over us.
Mei Lin was very still now.
Kean's usual smirk had vanished entirely.
The projection faded slowly.
But the fractures remained burned into my mind.
As the hall emptied, the air felt heavier than before.
No laughter and no casual chatter.
Just quiet processing.
Kean exhaled sharply. "So. Mutating beasts. Organized demons. Possessed villagers. That's… comforting."
Mei Lin elbowed him weakly, but even she didn't protest much.
I walked a step behind them, letting my mana extend outward without thinking.
Scanning.
The Academy felt stable, I sensed layered wards and clean circulation.
But beyond it?
If miasma integrated into mana currents…
If ruptures were distortions in space itself…
Then they weren't just tears.
They were structural failures.
Could I sense them from here?
I pushed my awareness outward cautiously.
The mana at the Academy's edge felt slightly thinner.
It was not corrupted, but somehow already felt a bit strained.
Like fabric pulled too tight.
My chest tightened.
If space was fracturing…
Then my magic wasn't just mobility.
It was architecture.
And architecture could collapse.
Or be reinforced.
I still couldn't remember the original plot clearly.
Just the feeling.
The shock.
I exhaled slowly.
I wasn't strong enough yet.
Definitely not strong enough to stabilize ruptures,
Not strong enough to mend boundaries between realms.
But I could train.
Harder.
Because this wasn't just about subtle interventions in classroom formations anymore.
It wasn't just about improving teleportation.
This was about the balance of worlds
And if the boundary between realms was weakening,
then someone with Space Magic couldn't afford to remain mediocre.
Professor Qian's word echoed again.
I looked toward the horizon beyond the Academy walls.
The sky looked normal.
But now I knew better.
Somewhere beyond that calm surface,
the world was cracking…
And I intended to understand exactly how.
