The Inner Sanctum was Supposed to be a sanctuary. A quiet, pitch-black void where a mage could organize their thoughts and regulate their core.
Right now, the darkness was suffocating.
Neo drifted in the formless expanse. His spiritual projection was battered, the edges of his consciousness fraying. His Core, usually spinning with vibrant, overwhelming energy, was reduced to a dull, flickering ember. It was barely maintaining his heartbeat in the physical world.
He was dying. The blunt force from the Expert-rank spell had ruptured his internal organs.
A deep, heavy vibration echoed through the void. It didn't originate from his core. It came from the absolute, uncharted depths of his own soul.
Neo weakly turned his mental focus toward the sound.
It was the exact sensation he had experienced years ago. On the day he had forced his awakening, just before he breached the bottleneck, he had felt an unseen force pull at him. It had felt ancient. It had felt agonizingly lonely.
He had ignored it then.
But now, the force wasn't just pulling. It was surging.
The darkness in front of him began to writhe. A deep, blood-red hue bled into the void, illuminating a terrifying, ancient pressure that coalesced into a massive, formless shape.
A voice resonated through the Sanctum. It didn't sound human. It sounded like the grinding of tectonic plates and the whispering of a thousand forgotten ghosts.
"Do you want to protect what is important to you?"
Neo didn't hesitate. He didn't care what the entity was. He didn't care about the consequences. The image of the assassin raising a serrated blade over his sister's head burned fiercely in his fading mind.
'Yes,' Neo answered, his voice echoing with absolute, desperate conviction.
"Then let me out."
Neo wasn't in a position to negotiate morality. He had taken an oath to protect his family. If he had to forge a pact with a demon to keep that promise, he would sign the contract in his own blood without blinking.
'Take it,' Neo commanded, completely surrendering his control over his center.
'Take whatever you need. Just save them.'
The moment the thought formed, the dark red energy exploded.
It rushed forward like a tidal wave of blood, instantly swallowing Neo's flickering core and wrapping entirely around his consciousness. It felt like a heavy, burning seal locking into place directly over his soul.
The crushing weight of the ancient energy forced his spiritual body down, drowning him completely in the crimson darkness until his self-awareness violently shattered.
In the physical world, the damp stone bunker was silent, save for the heavy footsteps of the Expert-rank assassin closing in on the corner.
The shadow-mage raised his serrated blade, his eyes locked onto Caelum's defiant, tear-streaked face.
"Don't worry, little lord," the assassin mocked. "It will be quick."
He swung the blade down.
The air distorted. A sound like a massive, rusted iron bell being struck underwater violently shook the entire underground chamber. The ambient mana didn't just tremble; it shattered.
The assassin froze, his blade stopping mere inches from Caelum's face.
Every shadow-mage in the room whipped their heads around. Their survival instincts blared.
Lying against the far wall, the broken, bleeding body of the white-haired boy was completely engulfed in a terrifying, dark crimson aura.
The energy wasn't structured. It wasn't an element. It was a thick, viscous miasma that practically burned the air around it.
Slowly, smoothly, defying all laws of biology, the boy stood up. His broken bones snapped back into place with sickening crunches, rapidly healed by the unnatural red energy.
Neo opened his eyes.
They weren't deep blue anymore. They were a glowing, piercing, absolute crimson. The miasma swirled around his white hair, making it dance in a bloody wind.
He slowly raised his hands, clenching them into fists. He stared at his knuckles, bathed in the red light.
His expression was completely devoid of its usual pragmatic calm. Slowly, his lips twitched upward.
It wasn't a smile. It was a twisted, unhinged grin that stretched entirely too far across his young face.
"Heh... hehehehe..."
A low, raspy chuckle escaped his lips, building into a full-blown, maniacal laugh that echoed off the stone walls. It didn't sound like Neo. It sounded ancient, chaotic, and absolutely delighted to finally be awake.
The Expert-rank leaders exchanged a horrified glance.
"What is that?" one of them hissed, instinctively stepping back.
"That's not a child's aura. That's a monster."
The boy stopped laughing. His crimson eyes locked onto the nearest Adept-rank assassin.
He didn't run. He didn't cast a spell. He simply vanished from the wall and materialized directly in front of the cloaked assassin.
It wasn't a mortal speed. It was a spatial tear.
The assassin didn't even have time to activate his shadow-shift.
The boy raised his hand.
[ Unnamed Art: Siphon ]
He lightly flicked his index finger against the center of the assassin's chest.
The red energy surrounding his finger violently expanded upon contact. The result was devastating. The upper half of the assassin's body simply ceased to exist, atomized in a spray of blood and shredded cloth. The headless, armless lower half crumpled uselessly to the stone floor.
The twisted, maniacal smile on the boy's face didn't falter.
"Heh... heh... hehehe..."
He casually leaned over the remaining bloody half of the corpse. The dark red miasma instantly lashed out, wrapping around the dead flesh. In seconds, the body dissolved entirely into glowing red particles, which the boy effortlessly absorbed directly into his own skin.
[ Vitality absorbed... ]
[ Mana Capacity increased... ]
The sheer horror of the display paralyzed the remaining assassins.
As the body was absorbed, the crimson aura around the boy surged, growing significantly denser. The invisible barrier holding his rank shattered audibly. The absorbed life force catapulted his core directly into the Intermediate stage of the Apprentice rank.
The temperature in the room dropped to an absolute, biting zero. The remaining assassins felt their blood run cold.
"Kill him!" the leader screamed, completely losing his professional composure.
"All of you, attack at once!"
The boy just tilted his head, his twisted smile widening.
It wasn't a fight. It was a slaughter.
He moved through the room like a blood-soaked phantom. He didn't use structured spells. He used the raw, devastating physical reinforcement of the red miasma.
An Adept lunged, swinging a short sword. The boy didn't dodge. He caught the steel blade with his bare hand. The metal hissed, melting instantly under the corrosive heat of the crimson aura.
He grabbed the advancing Adept by the throat. His small fingers crushed the man's windpipe before the assassin could turn to shadow. The red miasma enveloped the dying man.
[ Vitality absorbed... ]
[ Mana Capacity increased... ]
He batted away a dark-elemental spell from the second Expert-rank leader, the magic completely disintegrating upon contact with his miasma. He closed the distance in a blur, grabbed the Expert by the face, and slammed his head into the solid stone floor so hard the entire bunker shook.
Absorb... Grow... Smile...
Within a minute, his rank skyrocketed again, completely bypassing the boundaries of normal magical progression. He broke into the Peak of the Apprentice rank, entirely fueled by the life force of the men he had butchered.
Finally, he turned his glowing crimson eyes toward the last remaining assassin—the leader who was still standing frozen near the children in the corner.
The assassin dropped his serrated blade. His legs gave out, and he fell to his knees. His cowl fell back, revealing a pale, terrified face.
"P-Please," the elite killer begged. His voice cracked with raw terror as the blood-soaked child slowly walked toward him.
"Have mercy. I was just following orders!"
The boy stopped in front of the kneeling man. He didn't look like he was even conscious of the words being spoken.
"Heh... hehehehe..."
He simply stared down at the trembling assassin, his head cocked to the side, maintaining that horrifying, unhinged grin.
He raised his hand, placing it gently on the top of the assassin's head.
[ Unnamed Art: Siphon ]
The man screamed.
The shadow-mage's body violently imploded under the pressure of the red energy, leaving nothing behind but a cloud of dark dust that was instantly absorbed into the boy's aura.
[ Vitality absorbed... ]
[ Breakthrough Initiated... ]
[ Rank Up: Adept (Early Stage) ]
The bunker was finally quiet.
The boy stood in the center of the room, completely surrounded by the swirling, dark red miasma. He slowly turned around, his crimson eyes locking onto the corner.
Caelum and Lyra were still huddled there.
Caelum had pushed himself in front of his sister again, his small arms spread wide. He was shaking violently, tears streaming down his face, absolutely terrified of the monster that had just slaughtered a room full of elite killers.
The boy took a slow, deliberate step toward them. His expression didn't change. The twisted smile remained plastered on his face as the heavy red energy whipped around his white hair.
He stopped just a few feet away, towering over the cowering twins.
The silence in the room was deafening.
Suddenly, Lyra broke.
She didn't scream. She didn't hide. She ignored her brother's protective arms, pushed past Caelum, and stumbled forward on her wobbly legs.
She walked directly up to the terrifying, blood-soaked boy and threw her arms around his waist, burying her face into his dirty tunic.
The boy froze.
His hand, heavily imbued with the volatile red energy, slowly raised into the air. It hovered directly over Lyra's white hair.
But before the hand could descend, the boy's entire body jerked violently.
His twisted smile faltered. His crimson eyes widened, the dark red glow flickering wildly as the deep blue irises underneath fought desperately to resurface.
A voice—cold, furious, and overwhelmingly familiar—suddenly echoed entirely inside the boy's own head. It was Neo's voice, ringing out with the absolute, unyielding authority of a soul taking back its vessel.
'Don't you dare touch my sister.'
The red energy violently retracted, snapping back into the depths of his Dantian like a whipped dog.
The boy's eyes rolled to the back of his head. His body went completely limp. He collapsed heavily onto the cold stone floor, utterly unconscious.
