Revchi Salik would never forget the person responsible for putting him in this prison.
No matter what, he had once been a Magic Knight of some repute.
To be defeated by three brats in a border village—that wasn't just humiliation. It was a stain he could never wash away.
He had sworn that the moment he left this prison, he would hunt those three down and exact his revenge.
What he never expected…
Was to see one of them here.
Wait.
Why was this brat here in the first place?
Yuuki looked at Revchi's furious expression inside the cell and instead smiled faintly. From his arms, he took out two grimoires, selecting one and raising it toward Revchi.
The grimoire trembled slightly, releasing a dim glow.
"…So, it is this one."
Yuuki spoke softly.
In the prison, mages weren't just sealed of their mana—their grimoires were confiscated and separately restrained to prevent accidents.
Seeing Yuuki holding his grimoire, Revchi froze.
Before he could even process what was happening—
BOOM!
The cell housing him exploded outward.
Before Revchi's eyes, wide with disbelief, his grimoire was devoured by Yuuki's own.
And in the next instant—
Yuuki was already standing in front of him.
"Y-You… what are you going to do?!"
Revchi's face drained of color as he instinctively shrank back.
"Obviously," Yuuki replied calmly,
"I'm here to deal with you."
He flicked his finger.
A compressed bolt of mana shot forward like a bullet.
"No— I—!"
Revchi didn't even get to scream.
His head burst apart like a smashed melon.
Yuuki erected a mana barrier in front of himself, blocking the spray of blood and shattered matter.
Feeling the negligible increase in mana within his body, Yuuki paid it no mind.
What mattered wasn't the mana—
It was Revchi's magic.
Among all the abilities in this prison, only two interested him:
Chain Magic, and Permeation Magic.
Chain Magic wasn't Underworld-tier magic, but its sealing property made it devastating against human mages—capable of deciding victory in an instant.
And magic could evolve.
With Yuuki's growing strength, the sealing effect itself might become even more terrifying.
"…Next cell."
Yuuki turned around, picked up the guard who had collapsed to the floor, pale and shaking, and headed toward Gueldre Poizot's cell.
Two minutes later.
Yuuki arrived.
Gueldre's cell was noticeably larger—and far cleaner—than Revchi's.
The plump man himself sat comfortably cross-legged on the wooden bed, looking completely at ease.
A merchant by origin—and a former Magic Knight captain known for dealing rather than fighting—Gueldre had lost all his official assets due to his charge of treason.
But those were only the assets on paper.
Spending a little money to live comfortably in prison was hardly difficult.
"Oh? You managed to break in this far?"
Gueldre chuckled strangely, his gaze sliding past the trembling guard before settling on Yuuki.
"Looks like things are going badly in the capital."
Yuuki was mildly surprised by Gueldre's lack of panic, but he didn't dwell on it. He raised the second grimoire and aimed it at Gueldre.
Nothing happened.
"…What?"
Yuuki frowned slightly and glanced at the guard.
"That's impossible! That is his grimoire!" the guard cried in panic.
Yuuki could tell—he wasn't lying.
Then the problem lay with Gueldre himself.
"…So you were prepared."
Yuuki tossed the guard aside and looked coldly at Gueldre.
Gueldre laughed.
"Heh. Trying to use my grimoire against me?"
"I'll guess—you're with the Eye of the Midnight Sun."
"I knew they wouldn't be wiped out so easily. With enough money, most problems disappear."
"I retrieved my grimoire long ago. Just didn't expect you to move this fast."
He raised a finger.
A grimoire glowing faintly purple floated before him.
"Permeation Creation Magic — Invisible Soldiers!"
Gueldre flipped off the bed and immediately activated his spell.
This was a once-in-a-lifetime chance.
He was escaping.
BOOM!
The reinforced cell was torn apart by invisible force as unseen soldiers charged toward Yuuki.
To Yuuki's Ki perception, their movements were crystal clear.
"Fire Spirit Magic — Salamander's Breath."
Yuuki sneered.
Unlike Gueldre himself, these created soldiers could be attacked by magic.
ROOOAR!
Scorching flames flooded the cell, melting everything in their path.
The invisible soldiers were incinerated the moment they touched the fire.
Along with them—
The unfortunate guard.
Yuuki wasn't bloodthirsty, but that guard had witnessed the devouring of grimoires.
From the moment Yuuki entered this prison, the man was already dead.
"…A fire spirit—Salamander?!"
Gueldre panicked, immediately activating his magic.
Permeation Magic — Invisible Explorer!
His body vanished.
"…Gone? Do you really think you can escape?"
Yuuki's gaze swept the inferno.
Through Qi, Gueldre's location was unmistakable—running through the flames toward the prison exit.
Permeation Magic nullified mana detection and magical attacks.
That was what made it terrifying.
Without Qi, Yuuki would've been helpless.
But this magic had one fatal flaw—
It couldn't block pure physical force.
BOOM!
Yuuki crouched, plunged both hands into the ground like blades, tore free a boulder taller than a man—
And hurled it.
"What?!"
Gueldre turned just in time.
CRASH!
The impact smashed him into the wall. Blood sprayed from his mouth as his face went deathly pale.
Yet even then—
He remained invisible.
Impossible…!
How did he find me?! Luck?!
Since mastering Permeation Magic, Gueldre had been virtually untouchable—
except once.
By that anti-magic brat.
And now—
Once again.
