The Void Vault was a cathedral of absolute, shadowless white.
It was a place of silence. A place of perfection.
But right now, it was a high-stakes laboratory where the very laws of physics were being systematically bullied into submission.
Lencar Abarame sat at the absolute center of the expanse. His legs were crossed, his spine was straight, and his hands rested loosely on his knees.
On the outside, he looked like a statue of a monk. A man who had found inner peace.
On the inside? He was losing his damn mind.
"The 'Smart Skin' is functional," Lencar muttered, his voice echoing in the hollow vacuum of the vault.
"In any standard engagement, it's a solid B-plus. It blocks. It deflects. It's reactive. It's exactly what a 'model student' mage from the Clover Academy would aim for after ten years of training."
He opened one eye, staring down at the palm of his hand. He could see the faint, almost invisible shimmer of mana clinging to his skin like a second, translucent epidermis.
"But it's still a drain," he grumbled. "A massive, glaring, inefficient energy sink."
He clenched his fist. The shimmer flared for a millisecond, then settled.
"Every time someone hits me, I have to pay the mana tax. Every kinetic impact requires a corresponding output from my core to maintain the shield's integrity. In a battle of attrition against a Zero Stage monster... I'm just a high-capacity battery waiting to run dry."
His analytical mind, forged in the fires of 21st-century data analysis, began to run the numbers.
He visualized the graphs. The mana consumption curve was linear. In a prolonged fight against someone like Kael Vortigen, the curve eventually crossed his regeneration rate.
And at that intersection? He was a dead man.
Sure, he had the Breath of Yggdrasil. He had the Quintessence. He could probably outlast most people on the continent just by standing in his private dimension.
But the "Sect Master" mindset he had adopted wouldn't allow for such a sloppy, lazy solution.
The goal wasn't just to survive. The goal was Absolute Reciprocity.
Or, in layman's terms: Self-sustenance.
"I don't want to just block the hit," Lencar whispered, his eyes narrowing. "I want to own it."
He visualized the loop construct he had salvaged from the ancient, rotting rune books Garrick had brought him. It was a beautiful, terrifyingly efficient circle of geometric logic.
The theory was simple. The implementation was hell.
If he could weave this specific rune into the very fabric of his Mana Skin, the kinetic energy of an enemy's sword strike—or a fire spell, or a boulder—wouldn't just be deflected.
It would be converted.
The impact would be the fuel. The kinetic energy would be stripped of its momentum and fed directly back into his meridians as raw mana.
The more he was hit, the more mana he would have.
He would become a perpetual motion machine of war. A black hole of kinetic energy. A god-tier tank that got stronger the more you tried to kill him.
"First attempt," Lencar said, centering his breathing. "Let's try to be civilized about this."
He closed his eyes. He reached into his Stage 3 Peak mana core.
He didn't pull a torrent. He pulled a thread. A single, hair-thin filament of emerald-tinted mana.
With the precision of a master watchmaker, he began to guide that thread to the surface of his skin. He started to weave it.
Line by line.
Angle by angle.
He was drawing the complex, interlocking loops of the ancient rune directly over his forearm. It was like tattooing himself with liquid light.
The air around him began to hum. A low, vibrating frequency that made the marble floor beneath him tremble.
A faint, emerald glow began to pulse just beneath his pores.
"Come on... just close the circuit... match the frequency..."
Snap.
The mana structure flickered violently, hissed like a dying snake, and dissolved into a useless mist of green sparks that faded into the white air.
Lencar didn't move. He didn't even flinch. He just let out a long, heavy, annoyed breath.
"Again," he muttered. "The frequency of the Smart Skin is too jittery. The reactive pulses are shaking the anchor points of the rune loose before I can finalize the seal."
He recalibrated his mana output. He adjusted the tension.
Second attempt.
Failure. The rune inverted and tried to eat his own mana.
Third attempt.
Failure. The loop was too tight and caused a localized mana burn on his wrist.
By the tenth attempt, the front of Lencar's shirt was soaked with sweat. His jaw was clenched so tight his teeth were aching.
Every single time the loop tried to actually close—the exact moment the recycling process was supposed to initiate—the entire structure collapsed like a house of cards in a hurricane.
"It's incompatible," Lencar whispered.
His voice was cold. It was the voice of a man who had just spent ten hours debugging a code that refused to compile.
"The modern mana signature I've developed... it's too 'noisy.' It's too chaotic for the ancient, rigid logic of these runes. It's like trying to run the world's most advanced technology on a rotting, water-damaged motherboard from the eighties."
He stood up abruptly. His joints popped like dry kindling in the silence.
He began to pace the white floor. His shadow, cast by the unnatural light of the Vault, stretched long and jagged against the pristine marble.
Frustration was an emotion he tried to avoid. It was a waste of processing power. It clouded the analytical mind.
But as the hours ticked away, the absolute, mocking silence of the Vault began to feel like a heavy weight.
He checked his internal clock.
Forty hours.
Forty hours before he had to step out of this sanctuary. Forty hours before he had to put on that stained apron in Nairn, smile at the regulars, and pretend he was just a "normal guy" who worried about the price of potatoes.
He didn't have time for "civilized" anymore.
"The rune won't be correctly drawn on the surface," Lencar muttered.
His eyes narrowed behind the dark slits of his mask. A cold, reckless light began to shine in his pupils.
"If the surface is too noisy... then I'll just have to go deeper."
He sat back down. But this time, he didn't reach for his mana with a gentle, guiding touch.
He didn't treat it like a thread.
He gathered his Stage 3 Peak reserves—the oceanic pressure of his core—into a single, concentrated, razor-sharp point.
He wasn't going to layer the rune on his skin anymore. That was the "safe" way. The "Magic Knight" way.
He was going to carve it directly into his spiritual foundation. He was going to etch the loop into his very meridians.
"Forced integration," Lencar said, his voice dropping to a low, dangerous register. "If this goes south, it's going to be a great mess to clean up."
He gripped his knees so hard his knuckles turned a ghostly, bloodless white.
He directed the raw mana flow. He visualized the loop construct. And then, he forced it.
He drove the mana into his own flesh, past the skin, past the muscle, and directly into the channels where his soul met his body.
The pain was not physical.
It was an existential agony.
It didn't feel like a knife or a fire. It felt like someone was trying to rewrite his DNA using a hot poker and a rusty, jagged saw. It was the sound of a thousand glass windows shattering inside his skull.
"ARGH!"
A strangled, guttural cry escaped his throat.
The green light of the rune didn't just glow this time. It burned.
It turned from a soft emerald to a harsh, blinding neon.
Suddenly, the rune began to draw in the ambient Quintessence of the room. It didn't sip it; it gulped it. It was a violent, unregulated suction. The air in the Vault started to swirl, a mini-cyclone forming around Lencar, pulling at his clothes, whipping his hair.
The loop closed.
For a single, glorious, terrifying millisecond, Lencar Abarame felt a power that defied all magical logic.
He felt the universe pause.
He felt as if he could see the atoms in the air. He felt as if he could reach out, catch a falling star, and turn it into a snack. He was the center of all things. He was the perpetual motion machine.
He was a god.
Then—the universe pushed back.
BOOM!
A shockwave of raw, distorted, and pressurized mana exploded outward from Lencar's chest.
It wasn't a spell. It wasn't an intentional release. It was a catastrophic system failure.
The force of the explosion threw his body across the Vault like a discarded doll. He flew through the air, his black cloak billowing, and slammed into a massive stone pillar with a sickening, heavy thud.
