Zen froze, hand hovering over the paper.
Then he picked it up.
The letter was folded once. Heavy stock. No seal. No signature—because it didn't need one.
Zen unfolded it carefully.
Zen,
Your mind is willing.
Your body will fail first.
I've had a full container of high-grade restorative potion delivered to the Warrior Hall.
It's keyed to you.
Use it.
Punch the dummy.
As hard as you can.
Again.
And again.
Don't pace yourself.
Don't measure progress.
Break your limits and let the potion do the rest.
If your hands fail before your will does, you're doing it right.
—V
Zen stared at the last line.
No concern.
No encouragement.
Just instruction.
"…Of course you planned this," he muttered.
He folded the letter and slid it into his pocket.
Then he turned toward the training floor.
The reinforced dummy stood where it always did—scarred, cracked, repaired more times than Zen could count. Beside it sat a sealed container, crystalline and heavy, faintly glowing with dense restorative liquid.
Zen picked it up, uncorked it, and took a long swallow.
Heat flooded his chest immediately—sharp, medicinal, alive. His muscles tightened reflexively as the potion began circulating, priming his body rather than fixing it.
"Alright," Zen said quietly. "Let's see."
He planted his feet.
He didn't warm up.
His fist drove forward.
The impact cracked the dummy's outer layer. Pain flared instantly—sharp, deep, familiar. Skin split across his knuckles.
Zen hissed—but didn't pull back.
He struck again.
And again.
Knuckles screamed.
Bones protested.
Pain stacked faster than his body could adjust.
He stepped back just long enough to grab the container and drink again.
The potion burned on the way down.
Not gentle healing—forced repair.
Skin crawled as it sealed. Bones realigned with dull, grinding pressure. The pain dulled—but didn't disappear.
Temporary.
Zen exhaled once and went back in.
Minutes blurred.
Then hours.
The dummy fractured and was replaced.
The floor beneath his feet was swapped out mid-session by automated systems responding to structural damage.
Zen didn't stop.
He drank.
He punched.
He broke himself.
Again.
Again.
Again.
By the time the container was half empty, his arms were shaking uncontrollably. His hands were swollen, raw, barely closing into fists.
He drank again.
The potion struggled now—repairs slower, heat lingering longer. His body resisted being forced back together this many times.
"Not enough," Zen whispered.
He hit harder.
When the container finally dimmed, its glow fading to nothing, Zen staggered back. Sweat dripped from his chin. His chest rose and fell in heavy, controlled breaths.
The dummy stood dented and fractured in front of him.
Zen flexed his fingers.
They hurt.
Badly.
Good.
He turned toward the exit, already thinking about food, rest—about coming back tomorrow and doing this again with a fresh container.
That's when the air shifted.
Not inside the hall.
Outside.
A distant pressure rolled through the academy—subtle, wrong, like the world drawing a breath it shouldn't have been able to take.
Zen stopped.
"…What was that," he murmured.
Far above him, something struck the academy barrier.
And this time—
It didn't bounce.
Meanwhile in the room next door,
Aren's fist went through the dummy.
Not into it.
Through it.
Iron Fist wasn't a technique anymore. It was a state. Mana wrapped tight around his forearm, compressing, hardening, devouring impact instead of dispersing it. The reinforced training dummy folded inward as if it had been swallowed, its core collapsing before the sound of the strike even finished forming.
Fragments clattered across the floor.
Aren didn't stop.
He stepped forward and struck again.
The next dummy didn't shatter—it ceased. The iron-bound plating crumpled, mana channels burning out as his fist passed through the space they had occupied. The air rippled briefly, protesting the force it had just failed to contain.
Aren exhaled through his nose, shoulders steady.
Good.
Still clean. Still controlled.
He rolled his wrist once, mana cycling back into place, then set his stance again. The hall was quiet except for the low hum of reinforcement systems rebuilding what he destroyed.
Another dummy slid into position.
Aren raised his fist—
And felt it.
Not pain.
Not pressure.
Impact.
Something struck the academy barrier.
Hard.
The mana around his arm wavered for a fraction of a second. Just enough for Aren to notice. His fist stopped mid-motion as the sensation rippled through the hall, through the stone beneath his feet.
That wasn't a fluctuation.
That was contact.
Aren straightened slowly, eyes lifting toward the ceiling.
"…That wasn't a drill," he said under his breath.
The reinforcement systems hesitated.
Then, somewhere far above the Warrior Hall, the barrier rang—a deep, resonant vibration that carried through the academy like a struck bell.
Aren clenched his fist, Iron Fist flaring instinctively.
Whatever had just hit them—
It had meant to be felt.
Evan was on the top floor when the light changed.
Not dimmed.
Not flared.
It warped.
He stepped closer to the tall window, eyes narrowing as the sky beyond the academy barrier bent inward like glass under pressure.
"…What the hell am I looking at," he whispered.
Then he saw it.
An airship.
Not academy-built.
Too angular. Too dark.
Its hull was etched with unfamiliar markings, mana thrusters flaring in controlled bursts as it hovered just outside the barrier.
And it was firing.
Not wildly.
Not recklessly.
Each strike hit the same region, over and over, testing the barrier's response.
The barrier rang.
Evan's heart slammed against his ribs.
"That's… that's not possible," he muttered.
He activated his communication rune—but not the public channel.
Private.
First Zen.
Then Aren.
Then Rex.
Then Niel.
"Answer," Evan said sharply. "Now."
The first response came from Zen, breath still uneven. "Evan? What's wrong?"
Evan didn't look away from the window.
"There's an airship outside the barrier," he said. "Not ours. It's attacking."
A beat of silence.
"…An airship?" Rex said. "You sure?"
"I'm watching it," Evan snapped. "It's adjusting fire patterns. This isn't random."
Another impact slammed into the barrier. The mana field rippled violently, stress lines flashing for a fraction of a second.
Aren's voice came through next, tight. "I felt that."
"You should have," Evan said. "It hit hard enough to shake the towers."
Niel didn't speak immediately.
Then, quietly, "This didn't happen before."
Evan swallowed.
"…Yeah," he said. "That's the problem."
He forced himself to breathe, mind racing. In his past life, the academy had never been attacked like this. Not openly. Not with an airship. Not while students were inside and instructors were gone.
This was new.
And new meant uncontrolled.
"Listen to me," Evan said, voice lowering. "I don't know how long the barrier holds. But if it breaks, it won't be clean."
Zen cursed softly. "What do you see?"
Evan leaned closer to the glass, eyes tracking the ship's movement.
"Multiple mounted cannons," he said. "Mana-charged. Coordinated firing. Whoever's piloting that thing knows barriers."
Rex let out a slow breath. "So this isn't a scare."
"No," Evan replied. "This is an entry attempt."
Another strike hit.
The barrier didn't ring this time.
It cracked—just for a heartbeat.
Evan's hand tightened around the rune.
"Get ready," he said. "All of you. Gear up. Stay together."
A pause.
Then Aren spoke, steady and dangerous. "If they get through—"
"They won't be facing teachers," Evan finished. "They'll be facing us."
Outside the window, the airship shifted position slightly.
Adjusting.
Learning.
And Evan knew, with a cold certainty that settled deep in his chest—
Whatever this was,
it wasn't supposed to happen.
The airship drifted sideways, engines flaring as it adjusted its angle.
Not retreating.
Repositioning.
Evan watched the barrier flex again, stress lines flashing and vanishing like cracks that refused to stay broken. His grip tightened around the communication rune.
"Get ready," he said quietly. "All of you."
No one argued.
Outside, the airship fired once more—deliberate, measured.
The barrier held.
For now.
Evan didn't step back from the window.
Because in all the lives he remembered,
this was the moment that never existed.
And that meant whatever came next
was going to change everything.
