The four remaining God Hounds did not possess souls. They possessed programming written in the absolute zero of the deep null. And that programming, despite the impossible, terrifying resonance radiating from the boy in front of them, demanded they complete the hunt.
They attacked in perfect, simultaneous synchronization.
It wasn't a physical charge; it was a collapsing dome of anti-reality. They leaped from four cardinal directions, their bodies elongating into streaks of pure, pitch-black erasure. They aimed to intersect at the exact spatial coordinates of Jax's heart, creating a localized singularity that would delete him from the timeline.
Cassian, paralyzed on the ground, could only watch.
Jax didn't brace himself. He didn't spark the Crimson-Dragon to burn them, or the Gravity-Well to crush them. In the state of Perfect Harmonics, violence was obsolete. Violence required friction, and Jax had become the frictionless center of the universe.
The first God Hound, striking from the vanguard, opened its jagged, null-space maw to consume Jax's face.
Jax simply raised his left hand and caught the beast by the snout.
The collision of anti-reality and Perfect Harmonics produced no sound. There was no shockwave. When Jax's prismatic aura touched the pitch-black void, the Hound's physical geometry actively rebelled against its own existence.
Jax didn't crush the snout. He corrected the math.
He sent a single, harmonic pulse through his fingertips. The pulse traveled through the Hound's anti-reality matrix, instantly rewriting its dark-matter code into ambient, harmless starlight.
The Hound didn't even have time to whimper. Starting from its snout and rushing down its spine, the pitch-black entity unraveled into a shower of glittering, iridescent mist. By the time Jax lowered his hand, the creature had simply ceased to be.
Three.
The remaining three Hounds did not abort the strike. They collided with Jax's position, their claws swinging in a synchronized vortex of null-space designed to shred his prismatic shield.
Jax didn't block. He stepped into the vortex.
Because his thirty cores were spinning in a flawless, infinite loop, Jax's body had become conceptually fluid. A Hound's claw swiped cleanly through his torso, but it didn't cut flesh. It passed through him as if he were a projection of light, the anti-reality finding nothing to grip, nothing to erase. Jax was mathematically occupying the space, but his physical density had shifted out of phase with their weapons.
As the second Hound's momentum carried it past him, Jax extended his right index finger.
He traced a single, glowing prismatic line across the Hound's flank.
[ ART OF THE SOVEREIGN: HARMONIC DISSONANCE ]
He didn't inject energy into the beast; he simply introduced a contradictory frequency into its localized physics. The Hound hit the black glass plateau and instantly shattered. It didn't break into pieces of flesh—it broke like a dropped mirror. Its anti-reality form splintered into a million jagged, two-dimensional fragments that passively dissolved into the heavy fifty-G atmosphere.
Two.
The final pair of Hounds realized close-quarters combat was a mathematical impossibility. They scrambled backward across the razor-sharp obsidian, their faceless heads twitching in unison.
They opened their maws and began to actively siphon the ambient Aether of Tartarus-4, combining their internal dark matter to manifest a massive, localized sphere of absolute erasure. The black sphere hovered between them, rapidly expanding, absorbing the light, the heat, and the very concept of gravity in a hundred-yard radius.
They launched the sphere directly at Jax. It moved with the terrifying, silent speed of a collapsing star.
Jax didn't run. He walked forward to meet it.
His boots crunched softly against the glass. The translucent, prismatic aura around him hummed a single, continuous, perfect note.
As the massive sphere of erasure engulfed him, Cassian held his breath.
For three agonized seconds, the sphere of anti-reality hung over the plateau, a terrifying black sun.
Then, a single crack of prismatic light appeared on its surface.
The crack spider-webbed, spreading across the void with blinding speed. The sphere didn't explode; it bloomed. The pitch-black anti-reality was violently converted into a lotus of pure, unadulterated white light, its petals expanding outward before dissipating into harmless rain.
Jax walked out of the dissipating light, completely untouched.
He didn't give the final two Hounds a chance to formulate another equation.
He closed the distance instantly, his body a blur of flawless motion. He placed a palm on the chest of the third Hound, and the back of his other hand against the flank of the fourth.
He didn't push. He exhaled.
The Perfect Harmonic state peaked, releasing a localized wave of absolute, uncompromising reality.
The two God Hounds turned entirely white. Their anti-reality matrices were flooded with so much pure, harmonized Aether that they were conceptually overwritten. They crumbled into perfectly white, sterile ash that blew away in the heavy, toxic winds of the dead world.
The plateau was empty. The hunters were dead.
Jax stood in the silence, his golden eyes staring out at the magma ocean. The universe was still. The fifty-G gravity was nothing more than a gentle embrace.
And then, the music stopped.
The Perfect Harmonic state was a miracle, but it was a miracle being channeled through a mortal, heavily traumatized teenage body. The infinite loop of the Bagua engine suddenly snagged on the sheer, catastrophic physical damage Jax had sustained.
The translucent, prismatic light shattered like a pane of glass.
Jax's golden eyes instantly rolled back into his head, the terrifying, divine authority vanishing from his face, replaced by the pale, slack expression of a dying boy.
The fifty-G gravity of Tartarus-4 immediately slammed back into him.
"Jax!"
Jax plummeted toward the razor-sharp obsidian, his body entirely limp.
Cassian moved. He didn't have his liquid-silver cores. He didn't have the Tier 10 Aegis. He had only the desperate, agonizing willpower of a man who refused to let his student die.
Cassian threw his battered, burned body across the black glass, sliding on his knees, his hands reaching out.
He caught Jax a fraction of an inch before the boy's skull struck the obsidian.
The impact of catching the hyper-dense, fifty-G weighted body nearly snapped Cassian's arms, but he held on, dragging Jax's limp form into his lap.
Jax was bleeding from every orifice. His internal organs were failing. His spiritual architecture—the magnificent thirty-core ecosystem—was completely, dangerously silent. The boy was in deep systemic shock, slipping rapidly toward a permanent erasure that had nothing to do with dark matter.
"No, no, no, you don't get to clock out yet, Monarch," Cassian wheezed, blood spilling over his own lips as he cradled Jax's head. "The universe just learned your name. You can't die in the first act."
Cassian's hands trembled. He was burned out. But an ancient Inquisitor always kept one final, heavily classified secret buried for absolute emergencies.
Cassian bypassed his shattered combat cores and reached into a dormant, heavily encrypted sub-layer of his marrow.
He forcibly sparked the Tier V [Regeneration-Spore] core.
It was a forbidden biological frequency, a core he had stolen from a Harvest Hive-Queen centuries ago and purified. Cassian coughed violently, his chest heaving as the core ignited.
He opened his mouth and exhaled a thick, glowing cloud of shimmering, emerald-gold spores.
The spores descended over them both like a localized, bioluminescent fog. The moment they touched Jax's broken skin, they went to work. The spores burrowed into his flesh, acting as microscopic, hyper-accelerated cellular surgeons. They violently knitted his fractured collarbone together. They sealed the ruptured capillaries in his lungs. They coated his burned, tearing muscles in a soothing, highly pressurized layer of biological Aether.
Cassian felt the spores washing over his own horrific Aether-burns, cooling the agony, forcefully repairing the nerve damage left by the Tier 10 armor.
It wasn't a gentle healing. It was aggressive, exhausting, and primal.
The bleeding stopped. The jagged, terrifying sound of Jax's failing lungs smoothed out into a slow, shallow rhythm.
Cassian slumped backward, resting against the intact pillar of black glass, his arms still wrapped protectively around the boy. The emerald-gold spores slowly dissipated into the freezing air, leaving behind only the heavy, oppressive silence of the quarantine zone.
Cassian looked down at Jax.
The boy's physical wounds were closed, but his eyes remained shut. His breathing was frighteningly slow. Cassian reached out with a tiny, fragile thread of Void-Sense to check Jax's marrow.
The thirty cores were intact, but they were in deep stasis. Jax's consciousness had retreated so far inward to protect itself from the trauma that he was completely unreachable.
"A coma," Cassian whispered to the dead world.
He leaned his head back against the cold obsidian, staring up at the shattered, starless sky. The Vanguard was burning. The Master of the deep null was waking up. The universe was tearing itself apart, and the only weapon that could fix it was currently sleeping in his lap.
Cassian let out a long, exhausted sigh, a weary smile touching the corners of his bloody mouth.
"Rest well, Jax," Cassian murmured, pulling his tattered coat over the boy's shivering shoulders. "When you wake up... I need to know what the hell you are. He chuckled.
