For the next hour, Zen and Maya descended deeper into the zone.

The deeper they went, the darker the neon smog became, clinging to the rusted skyscrapers like a physical weight. They encountered several more packs of low-tier monsters.

Zen let Maya take the lead on the smaller groups. He watched with quiet approval as she grew more comfortable wielding her staff, balancing her natural healing instincts with the predatory pull of the Leech spell. ANd soon she was getting better at draining the cyber-arachnids and lesser Synth-Hounds.

When a larger pack of mutated iron-boars charged them, Zen finally stepped in.

He didn’t even draw a weapon. He simply sidestepped the lead boar, coated his knuckles in heavy gold-purple Emperor mana, and punched straight through the beast’s reinforced skull.

But as they stepped over the smoking wreckage of the boars, Zen paused. He raised a closed fist.

Maya stopped immediately, her staff humming softly. "What is it? Did I miss one?"

"No," Zen replied in a low voice. He scanned the empty, ruined plaza ahead of them. "It’s too quiet."

"Isn’t that normal?" Maya asked, wiping a bead of sweat from her forehead. "This is my first time in a D-Rank zone, but I thought the stronger monsters just claimed larger territories."

"They do," Zen replied, crouching to inspect a deep, scorched gouge in the pavement. He touched the edge of the crater; the metal was still warm. "But the ambient mana here is extremely dense. A zone this rich should be crawling with Mid D-Rank strays fighting for scraps. Instead, we’ve only seen bottom-feeders."

The familiar blue screen materialized in Zen’s vision.

[System Alert: Probability Analysis Initiated.]

[Variable: Discrepancy in Sector 7 Monster Density.]

[Probability of natural monster migration: 3.1%]

[Probability of external human interference (Prior clearing): 96.9%]

[Conclusion: Hostile or competing entities are currently operating within the sector.]

Zen tapped the side of his mask, forcefully overriding his local comms to piggyback onto the Spymaster’s encrypted frequency.

"Nyx. You watching?"

"Obviously," Nyx’s dry, synthesized voice crackled directly into his earpiece. "The mortal has only tripped over her own boots twice. I’m taking notes."

"Run a full topological scan of the sector ahead and sync your stealth drones to my terminal," Zen ordered, ignoring the jab. "Someone is already here, and they’re carving a path straight to the core."

"One moment," Nyx muttered, the sound of rapid keystrokes echoing over the comms. "Ah. I see them. You have pests, Emperor. A six-man corporate strike team from Synapse Industries. They operate one of the largest networks of zone raiders and combat streamers in my domain. They are heavily armed, incredibly arrogant, and currently two miles ahead of you, heading for the Zone Boss."

"Can we beat them there?" Maya asked, stepping closer to Zen.

"We don’t need to," Zen said, his eyes locking onto a faint, secondary energy signature on his newly updated mini-map. It was a hidden, collapsed subway tunnel branching off the main path. "Synapse cleared the main road, but they missed a localized mana pocket underground. A hidden vault."

Maya’s eyes widened. "A vault? In a D-Rank zone?"

"It’s overflowing with raw energy," Zen said, standing up. "It will be packed with high-density materials. Exactly what I need for Aurelia’s tribute. We take the detour."

Zen led Maya down into the pitch-black subway tunnels. The air here was suffocating, thick with toxic spores and the grinding sound of metal on metal. The ambient mana was so dense it felt like walking through water.

The moment their boots touched the cracked tiles of the subway platform, the vault’s guardians woke up.

Dozens of blinding red optical sensors flared in the darkness. The horrifying sound of a hundred metallic legs skittering against concrete echoed through the cavern.

A swarm of D-Rank Mecha-Centipedes, each the size of a train car, began slithering down the massive support pillars. Their segmented bodies were forged from hyper-dense, rusted alloy, and their massive mandibles sparked with lethal, high-voltage electricity.

"Stay behind me, Maya," Zen commanded, his voice dropping an octave.

Maya didn’t argue. She slammed the base of her staff into the ground, instantly casting a wide, shimmering green barrier over them just as the first centipede lunged from the ceiling.

CRASH!

The beast slammed headfirst into Maya’s shield. The sheer kinetic impact rattled her teeth, and the concrete beneath her boots cracked, but the Emperor-infused barrier held firm. The centipede shrieked, its electrical mandibles sparking violently against the green magic.

Zen looked up at the monstrous insect.

For the first time since his core had been shattered months ago, Zen didn’t have to carefully measure his output. He didn’t have to worry about his mana channels cracking or his soul fragmenting.

His High C-Rank core was completely stable, burning like a localized sun in his chest.

He let the floodgates open.

A terrifying, suffocating wave of heavy gold-purple Emperor mana erupted from Zen’s body. The pressure was so intense it actually warped the air around him, forcefully pushing the toxic spores away.

Maya gasped, taking a step back as she felt the weight of the power he had been casually hiding.

Zen stepped through Maya’s barrier.

To the Mecha-Centipede, Zen was just prey. It reared back and lunged again, its jaws snapping fast enough to break the sound barrier.

But to Zen, the monster seemed to be moving in slow motion. The High C-Rank physical enhancements made his perception terrifyingly sharp. He could see the exact rotation of the beast’s gears, the flow of electricity between its segments, and the subtle, glowing weak point beneath its heavy armor plating.

Zen didn’t dodge. He planted his foot, coated his right arm in concentrated mana, and drove his fist forward to meet the beast head-on.

His fist slammed into the centipede’s hyper-dense skull. The alloy didn’t just dent; it completely caved in with a loud crunch. The kinetic shockwave of his punch rippled down the monster’s segmented body, blowing out its hydraulic joints.

Before the centipede could even register it was dead, Zen’s hand blurred. He bypassed the shattered armor, driving his fingers deep into the glowing electrical gap behind its head. With a brutal twist, Zen ripped his arm back out.

Sparks showered the platform. In Zen’s palm rested a glowing, heavily crystallized power core.

The centipede’s massive husk collapsed to the floor, instantly dead.

The rest of the swarm screeched in static fury and swarmed the platform.

Zen vanished.

He moved so fast he looked like a blur of dark fabric and deadly gold-purple light. He was incredibly accurate and precise. When two centipedes tried to crush him, Zen dropped low. He swept his leg to break the front jaw of one.

Then, he launched himself into the air. He landed hard on the back of the second centipede, driving his heel through its tough shell to crush its main power line.

Zen was not just fighting; he was collecting resources. He planned every move and every strong hit perfectly.

He didn’t use up his mana on showy spells or big explosions that would ruin the loot. Instead, he used his great C-Rank speed and strength to take apart the D-Rank monsters, just like a mechanic fixing a broken engine.

He quickly dodged a high-voltage attack. Then, he grabbed a centipede by its sparking jaws and used his raw physical power to flip the train-sized monster over his shoulder. It crashed onto its back, showing its soft underside. Zen pushed his hand in and pulled out a second core.

In just five minutes, the loud, mechanical screaming stopped.

The tunnel became completely silent again. More than a dozen huge, smoking metal bodies lay scattered on the ground.

[System Alert: Combat Concluded.]

[Loot Procured: D-Rank Mechanical Heart Stone x14.]

[Estimated Value: Exceptional. Suitable for High-Tier Crafting.]

Zen stood in the center of the carnage, his breathing completely even. He didn’t even have a scratch on his tactical suit. He casually wiped a smear of corrosive oil off his knuckles and tossed the glowing Heart Stones into his spatial storage ring.

He cracked his neck, turning back to look at Maya. She was still standing behind her green barrier, staring at him with her mouth slightly open.

"That covers the materials," Zen said calmly. "Now, let’s go see what Synapse Industries is up to."

They followed the collapsed tunnel upward, the sounds of heavy artillery fire and desperate shouting echoing closer and closer.

Zen placed a hand against a crumbling brick wall at the end of the tunnel. With a single pulse of Emperor mana, he blew the wall outward in a cloud of dust.

They stepped out onto a high overlooking ledge, arriving exactly at the sector’s central reactor core.

The arena below was a sprawling, ruined industrial plaza, illuminated by the flashing red lights of emergency sirens.

In the center of the plaza was the Zone Boss: a High C-Rank Titan-Class Arachnid. It was a massive, nightmarish spider made of black steel, its abdomen pulsing with corrosive green acid.

And the Synapse strike team was getting absolutely slaughtered.

Even with their sleek, white-and-silver high-tech armor and heavy plasma rifles, the corporate mercenaries were completely outmatched. The Titan-Arachnid moved with blinding speed, using its massive bladed legs to casually swat away their concentrated plasma fire.

Even though they had sleek, white-and-silver armor and heavy plasma rifles, they were no match for the zone boss. The Titan-Arachnid was incredibly fast, using its huge, bladed legs to easily knock away their strong plasma fire.

"Form up! Shield wall, damn it!" the Synapse Captain screamed. "Concentrate fire on its joints!"

A mercenary tried to flank the boss, but the arachnid simply spat a massive glob of green acid. The mercenary screamed as his energy shield instantly melted, forcing him to dive into the rubble to avoid being liquefied.

"They’re going to die," Maya whispered, peering over the ledge, her grip tightening on her staff. "They don’t have the output to break its outer shell."

Zen leaned casually against the broken railing, his Ghost Scrapper mask hiding a dark, calculating smirk.

[System Alert: Probability of Synapse Strike Team survival: 0.4%]

[Probability of Titan-Arachnid entering Enrage Phase within 60 seconds: 98.8%]

"Corporate mercs rely too much on their tech and completely ignore their actual mana cores," Zen noted coldly, watching the captain frantically reload his rifle. "They bought their way into a C-Rank fight with D-Rank skills."

"Are we going to help them?" Maya asked, looking up at him.

Zen pushed himself off the railing. The heavy, suffocating pressure of his High C-Rank aura began to bleed back into the air, causing the loose debris around them to float slightly off the ground.

"We are going to hijack their raid," Zen corrected, rolling his shoulders. "Watch and learn, Maya. This is how the Ghost goes to work."
