The Vanguard did not hesitate. The moment the white barrier dissolved into grey ash, the front line erupted.
A wall of golden mana-rounds cut through the dark, tracing arcs of blinding, clinical light across the transit corridor. The sound was deafening—not the chaotic boom of black-powder ballistic weapons, but the synchronized, high-frequency hum of hundreds of automated firing pins discharging in perfect unison.
Matthew did not retreat. He stepped forward, his obsidian left hand slashing through the air horizontally.
[Noble Art: Void Circuit – Localized Horizon]
The air in front of them fractured. A jagged, vertical tear of pitch-black static materialized a foot away from his hand, hanging suspended in space. The incoming golden rounds didn't bounce off; they didn't explode. The moment the tip of each projectile touched the border of the black static, its velocity dropped to absolute zero, its data unraveled, and it simply ceased to exist.
"Keep firing!" a Vanguard captain roared from behind a heavy barricade of polished white steel. "The anomaly's capacity has a limit! Overload the vector!"
The barrage intensified. The corridor became a tunnel of solid gold light, the sheer heat of the mana-rounds melting the rusted iron pipes along the ceiling. Stagnant water began to pour down from the upper conduits, vaporizing into thick clouds of white steam the moment it touched the superheated air.
"Matthew, they're shifting their formation," Lyra warned.
She stood directly behind his right shoulder, her sapphire eyes glowing with a sharp, clear intensity. The blue thread of the Null-Bridge around her neck was humming, vibrating in response to the massive intake of energy Matthew was pulling from the dark. "The back line... they're setting up three Censer-Tanks. They aren't targeting us. They're targeting the structural pillars of the corridor."
"They want to bury us," Matthew said, his voice echoing with that cold, double-layered resonance.
"I can hold the ceiling," Lyra said, her hands coming up to grip his shoulder. "But you need to clear the path. Now."
The moment her fingers pressed into his tattered cloak, a wave of deep cerulean energy surged across the Null-Bridge, flowing directly into his obsidian chest plate. The violent, erratic violet static drifting off his skin suddenly steadied, focusing into a dense, razor-sharp edge around his left arm.
The partnership was no longer a theory. He was the destruction; she was the stability that kept that destruction from tearing him apart.
Matthew lunged forward, abandoning the defensive horizon. He moved with a speed that defied his tattered frame, his obsidian boots leaving footprints of fine black ash on the concrete floor.
The Vanguard captain barely had time to adjust his rifle before Matthew was upon the first barricade.
Matthew didn't use a weapon. He simply reached out with his matte-black left hand and grabbed the top edge of the white-steel barrier. The pristine armor plating, backed by the divine logic of the Architects, didn't hold. The moment his fingers made contact, the structure lost its solidity. The metal became brittle, turning to black dust under his fingers as the Void unraveled its chemical composition.
"Get back!" the captain screamed, drawing a short, glowing mana-blade from his hip.
Matthew didn't look at him. He swung his obsidian arm in a wide arc. The violet static trailing from his fingertips cut through the air like a physical blade, striking the weapons of the entire front line. Rifles shattered into useless pieces of inert iron; armor chest plates cracked open, the golden runes engraved upon them dying instantly.
He didn't kill them. He didn't need to. He stripped them of their function, leaving a dozen heavy infantrymen standing in broken, powerless suits of iron, completely exposed to the dark.
"The Censer-Tanks!" the captain shouted over the comms, scrambling backward on the slick floor. "Fire the payload! Now!"
At the far end of the corridor, the three massive, white-armored vehicles groaned as their main turrets locked onto the center of the ceiling directly above Matthew and Lyra. The barrels began to glow with an intense, suffocating violet-white light—the purification code meant to collapse the entire transit sector.
Matthew stood in the center of the ruined front line, his human eye locked on the heavy artillery, his obsidian arm already gathering a dense sphere of absolute blackness.
