The deafening, ear-shattering shriek of a Tier-1 critical emergency alarm vibrated through the floorboards and rattled against Sebastian’s ribs. The soft, ambient white lighting of the massive vaulted room violently snapped to a harsh, strobing crimson.

The Grand Archons had been watching the multiversal broadcast. They had watched him crush their newly minted champion, Vargas, and they had watched him declare open war on their entire simulated religion. They knew exactly what he was, and they were officially in full, unadulterated panic mode.

[CRITICAL ALERT: ANOMALY ZERO RE-ENTRY DETECTED.] [THREAT LEVEL: APOCALYPTIC.] [INITIATING ABSOLUTE FACILITY LOCKDOWN.]

CLANG! CLANG! CLANG!

All around the sprawling, circular central platform, massive slabs of thick, impenetrable durasteel slammed down over every single archway and exit. The heavy blast doors locked into place with a series of deep, metallic thuds that sounded like the sealing of a cosmic tomb.

Sebastian didn’t run for the doors. He didn’t try to slide under them like an action hero. He just stood in the dead center of the platform, his hands casually stuffed into his pockets, his silver-tinged eyes tracking the frantic red warnings flashing across his vision.

"Locking me in a room with you," Sebastian muttered, a dark, utterly unhinged smile spreading across his pale face. "Bold strategy. Let’s see how that works out for your life expectancy."

A booming, synthesized voice echoed from the ceiling. It didn’t belong to a single entity. It was the combined, overlapping voices of the Grand Archons, heavily distorted by sheer terror and administrative rage.

"YOU WILL NOT REACH THE INNER SANCTUM, VIRUS!" the voice roared, the acoustic pressure physically pushing against Sebastian’s black coat. "YOU ARE A MISTAKE! A GLITCH IN THE GRAND DESIGN! AND YOU WILL BE PURGED!"

"Yeah, yeah, skip the monologue and get to the boss mechanics," Sebastian sighed, rolling his shoulders.

The ceiling above the central platform groaned.

Sebastian looked up.

High above him, the pristine white marble of the vaulted dome began to shift and dissolve.

Massive, geometric vents opened up, completely circling the perimeter of the room.

"ACTIVATING QUARANTINE PROTOCOL: RIVER OF CODE," the Archons announced. "ENJOY YOUR DELETION."

From the massive vents, a liquid began to pour. But it wasn’t water. It wasn’t even the highly corrosive, neon-blue acid from the Vanguard Syndicate’s Harvest Dens.

It was pure, unadulterated anti-virus software rendered into a physical, fluid state.

It looked like a cascading waterfall of blindingly bright, white-hot static. It hissed and popped as it hit the air, instantly vaporizing the ambient mana in the room.

SPLASH! SSSSSSS!

The moment the River of Code hit the polished obsidian and marble floor of the platform, the stone simply ceased to exist. It didn’t burn or melt. The physical rendering of the floor was actively deleted, leaving behind nothing but raw, empty wireframes that were quickly swallowed by the rising tide of white static.

"Holy shit," Sebastian’s deadpan demeanor finally cracked. His eyes widened as the localized reality around him began to actively dissolve. "Okay. That’s actually a problem."

The anti-virus fluid wasn’t just pooling; it was flooding the entire central platform at a terrifying speed. It was a localized server wipe designed to melt any unauthorized entity down to their base polygons and scrub them from the Ethereal Plane forever.

Sebastian couldn’t punch it. He couldn’t drop his [Concept of Mass] on it to crush it, because it didn’t have physical weight. It was pure, aggressive logic.

The white-hot static surged forward, a tidal wave of deletion rushing straight for his boots.

"Think fast, Seattle," Sebastian gritted his teeth.

He violently pulled his hands out of his pockets. He opened his glowing green Admin UI and forcefully engaged the [Code Compiler].

If he couldn’t fight the liquid, he had to build a boat. Or at least, a really, really sturdy umbrella.

Sebastian dropped to one knee and slammed both of his black-gloved hands flat against the remaining marble floor beneath him. He didn’t cast a standard defensive ward. A magical shield would just be registered as an unauthorized spell and instantly deleted by the anti-virus. He had to use the server’s own physical assets against it.

[Action Registered: Access Physics Engine - Terramancy: Reshape.] [Nexus Glitch Activated: Proficiency x10,000.]

"Build a wall!" Sebastian roared.

He didn’t just ask the system nicely. He forcefully grabbed the foundational rendering code of the entire Hub’s floor. He ripped the absolute concept of the marble, the bedrock, and the underlying durasteel out of the ground and violently dragged it upward.

RUMBLE! CRASH!

The entire platform violently bucked. A massive, ten-foot-thick dome of compressed, hyper-dense marble and steel erupted from the floor, perfectly encasing Sebastian in a crude, jagged igloo of physical matter just a microsecond before the River of Code crashed into him.

FWOOSH! SSSSSS!

The sound inside the dome was absolutely deafening. It sounded like a billion angry wasps were trying to chew their way through the stone.

The inside of the dome was pitch black, save for the glowing green interface hovering in front of Sebastian’s face. He kept his hands pressed flat against the ground, his body trembling with the sheer, ungodly exertion of holding the physical construct together.

The anti-virus didn’t stop. It washed over his makeshift bunker, actively eating away at the stone.

[Warning: External Shield Integrity at 80%... 70%... 60%...]

"Fuck me, it’s hungry!" Sebastian grunted.

Sweat poured down his face, stinging his eyes. The ambient temperature inside the dome skyrocketed as the friction of the deletion code grinding against the physical matter created a massive localized heatwave.

He couldn’t just sit here. The River of Code was aggressively chewing through his barricade. He could feel the ceiling of his dome getting thinner and thinner.

"Re-compile!" Sebastian shouted. He shoved more of his limitless, glitched mana into the floor, ripping more chunks of the Hub’s foundational bedrock out of the surrounding rooms and forcefully funneling them into his shield to replace the deleted layers.

It became a brutal, frantic battle of attrition.

The Archons poured millions of gallons of anti-virus data over him, and Sebastian desperately shoveled the server’s own architecture into the gap to plug the holes.

[Shield Integrity: 40%... 55%... 30%... 45%...]
