The journey to the Iron-Gate Pass took three days of traversing the lower ridges of the floating islands, where the air lost its crystalline purity and took on the heavy, metallic scent of damp earth and stagnant Qi. By the time Blake reached the mouth of the canyon, the sky above had turned a bruised, permanent violet, obscured by a ceiling of thick, unnatural clouds.
The Iron-Gate was once a vital artery for the Azure Vault, a terrestrial trade route that allowed the lower sects to transport raw ores to the refineries. Now, it was a wound in the landscape. Two massive obsidian pillars, each carved with ancient suppression runes that had long since flickered out, stood like tombstones at the entrance. Beyond them lay a narrow pass choked with a grey, powdery mist—the ash of a thousand failed rituals.
Blake stood before the threshold, the black-wrapped weight of Silence resting against his shoulder. He took a deep breath, feeling the air grate against his lungs.
[System Warning: High concentration of Necrotic Qi detected.]
[Atmospheric pressure increasing. Recovery rate reduced by 40%.]
"The grave doesn't welcome the living," Blake whispered to himself.
He adjusted his grip. He had discarded his academy robes for a simple suit of dark, reinforced leather—no flashy colors, no symbols of rank. He was here as a warrior, not a disciple. As he stepped across the threshold, the temperature dropped instantly. It wasn't the clean cold of the mountain peaks; it was the clammy, intrusive chill of a cellar.
He hadn't walked half a mile when the first one appeared.
It didn't roar. It didn't announce its presence with a flare of energy. It simply rose from the grey ash like a puppet being pulled by invisible strings. The Grave-Walker was a horrifying fusion of man and metal—its flesh had been replaced by a grey, stony substance, and jagged shards of iron-ore protruded from its joints. Its eyes were hollow pits, devoid of light or intelligence.
Blake didn't hesitate. He swung Silence in a low, horizontal arc, aiming to bisect the creature at the waist.
CLANG.
The sound was like a hammer hitting an anvil. The matte-black blade, which had sliced through Chen's spirit-sword, only bit an inch into the creature's stony hide. The vibration traveled up the handle, making Blake's 2nd-layer muscles hum with the shock.
The Grave-Walker didn't flinch. It swung a heavy, slab-like arm, the speed of the strike defying its lumbering appearance.
Blake used the Weightless Breath, drifting backward a split-second before the blow connected. The creature's fist smashed into a nearby rock, shattering the stone into dust.
No soul, Blake realized, his eyes narrowing. No spirit gate to sever. No blood to drain. It's just a mountain of compressed malice.
He shifted his stance, moving from the "Light" of his footwork to the "Heavy" of his physical foundation. If the edge wouldn't cut, he would use the weight. He gripped the center of the scythe's handle, spinning the weapon like a staff. He stepped inside the Walker's reach, delivering a thrust with the blunt end of the scythe directly into the creature's chest.
He channeled his 2nd-layer Vital Essence not into a sharp point, but into a Vibration Pulse—a technique he had visualized after watching the Iron Guard.
THOOM.
The Grave-Walker's chest-plate of stony flesh cracked. The internal structure, held together by necrotic Qi, shattered under the resonant frequency. The creature collapsed into a heap of grey rubble and scrap metal.
[Enemy Neutralized.]
[Vital Essence Harvest: 0.0 Units.]
[Note: Husks contain no harvestable soul energy.]
Blake frowned. This was the true danger of the Iron-Gate. In the valley, every kill made him stronger, fueling his recovery and growth. Here, every kill was a net loss. He was spending energy to survive, with no way to replenish it other than the slow, stagnant Qi in the air.
"This is why the Inner Sect stayed away," Blake muttered, wiping a smear of grey ash from his cheek. "It's a war of attrition."
He continued deeper into the pass. By the end of the first day, he had fought twelve more of the husks. Each fight was a grueling exercise in precision. He couldn't afford a single wasted movement or a single unnecessary flare of energy. He had to become a miser with his strength.
As night—or the darker version of the violet twilight—settled over the pass, Blake found a small alcove in the canyon wall. He didn't build a fire; the light would be a beacon for the things that hunted in the dark. He sat in the shadows, his back against the cold stone, and began to manually refine the thin, bitter Qi of the pass.
It felt like drinking silt. The necrotic energy tried to corrode his meridians, but his Void-Internalization acted as a filter, painstakingly stripping away the rot to find the tiny grains of pure essence.
[Refinement Rate: 10% of normal.]
[Physical fatigue: 15%. Recovery estimated: 6 hours.]
His body ached. The 2nd-layer breakthrough had made him stronger, but these Grave-Walkers were physically comparable to 4th or 5th-layer masters. They didn't have techniques, but they had a relentless, unyielding density that punished every mistake.
On the third day, the terrain changed. The pass widened into a valley of jagged iron-spires, and the mist turned from grey to a sickly, luminescent green. Here, the Grave-Walkers weren't alone.
Blake crouched behind a shard of obsidian, watching a pack of four "Stalkers"—smaller, multi-limbed versions of the husks that clung to the canyon walls. They moved with a jerky, insectile grace, their blades of bone-metal clicking against the stone.
"One week to reach the midpoint," Blake whispered, consulting the map Vane had given him. "Two weeks to the hive. I'm already at 70% energy."
He reached for a small leather pouch at his belt—one of the few Spirit Stones he had left from the arena. He looked at it, then put it back. Not yet. Save the stones for when the heart stops.
He unstrapped Silence. He decided to try something new—a merging of his Martial Intent and the Weightless Breath. He wanted to move so quietly that the husks' sensitivity to vibrations wouldn't trigger.
He stepped out from the shadow. He moved with a haunting, liquid motion, his feet barely touching the layer of ash. He was a shadow among shadows. He reached the first Stalker, his blade moving in a vertical arc that mirrored the falling of a leaf.
The blade found the "seam" where the necrotic Qi held the neck to the torso.
The head fell without a sound.
The other three Stalkers paused, their sightless pits scanning the air. Blake was already behind the second one.
Swish. Swish.
In three seconds, the clearing was silent again. Four husks lay in the ash.
Blake stood in the center, his breathing steady. He felt a flicker of pride, but it was quickly replaced by a cold realization. His hands were shaking. Not from fear, but from the constant, microscopic vibrations of the necrotic environment. It was trying to break him down, cell by cell.
"I am the weapon," Blake reminded himself, his voice a low growl. "A weapon doesn't tire."
By the end of the first week, Blake's appearance had changed. His leather armor was scored with deep gouges, and his face was gaunt, his eyes burning with a fierce, sunken light. He had reached the "Bridge of Sighs"—a narrow arch of stone that spanned a pit of boiling, green miasma.
At the far end of the bridge stood something different.
It was a Grave-Walker, but it was twice the size of the others. Its body was encased in a suit of rusted, ancient plate armor that seemed to have grown into its stony flesh. In its hand, it held a massive, notched greatsword that pulsed with a dark, rhythmic light.
[System Warning: Elite Grave-Guardian detected.]
[Estimated Power Level: Peak 5th Layer (Physical).]
[Combat Recommendation: Full output required.]
Blake felt the Divine Reaper stir in his spirit gate. It felt the threat. It wanted to emerge, to shroud the bridge in emerald fire and erase the Guardian from existence.
Blake's grip tightened on Silence.
"No," Blake whispered, his teeth bared in a grin that was more bone than flesh. "If I use you now, I've lost the lesson. This is my bridge to cross."
He stepped onto the arch. The Guardian raised its greatsword, the rusted metal screaming as it moved.
The battle for the Iron-Gate was no longer a mission for the academy. It was a crucible for Blake's soul. He was a 2nd-layer warrior standing against a 5th-layer mountain, with nothing but a black scythe and a will that refused to break.
