Chapter 80: Core Whispers, the Silver Moon Vortex, and the Key to Annihilation

The heavy alloy gate slowly opened amid the shriek of gears, revealing a deep metal staircase spiraling downward behind it. A breath of air rushed in, thick with the scent of concentrated ley-line sulfur, faint azure light of Order, and… a thread of icy, rotting stench. The air was heavy and viscous; every inhale carried a burnt taste of metal and overloaded energy. The emergency lights on the walls flickered between dim and bright, casting twisted, swaying shadows through the corridor lined with aged pipes and enormous rivets—shadows like ghostly claws choosing their prey.

The scan beam of the "Abyss Probe" stretched forward cautiously, like a blind man's cane. Wrench cowered behind Lin Mo; on the probe box's screen, the energy readings twisted violently—purple (rot) and blue (Order) waveforms writhed like two maddened giant serpents trying to devour each other, nearly bursting the display. "Interference's too strong, boss! Noise everywhere! The countdown signal and the distress signal… are completely overlapping down below!" His voice buzzed with a hollow echo inside the helmet, thick with terror.

Sister Ai Li walked ahead and to Lin Mo's side, her condition serving as the keenest detector. Deep within the wound on her left arm, that dark-purple tumor pulsed at an unprecedented frequency; each pulse brought drilling agony and a cold, gnawing erosion, while the purplish-black veins beneath her skin writhed faintly like living things. She pressed her lips tight, cold sweat dampening the hair at her brow, her icy eyes fixed dead ahead on the darkness, following the resonance between pollution sources to guide the way: "Turn left… energy nodes are denser… the corruption is intensifying… something is… whispering…"

Lin Mo gripped the "Ley Line Arbiter"; the dark-purple glow on the sword-guard emblem flickered like breathing, faintly synchronized with the pulse in Sister Ai Li's arm. The azure light of the Order's Anchor churned at full power within him, resisting the all-pervading spiritual erosion of rot and the maddening seduction coming from the mark itself. He followed Sister Ai Li's guidance, each step landing where the energy nodes were densest and the spatial structure relatively stable.

The corridor opened abruptly at its end into a vast, spherical space like a furnace at the earth's core. At the center of the space floated a colossal blue orb of light assembled from countless nested, precise geometric solids—the Sanctuary Core! Now, its originally steady flowing blue currents had grown chaotic and dim, and the orb's surface was webbed with purplish-black energy fissures! Directly beneath the orb, a grotesque device shaped like a heart, formed from twisted purplish-black crystal clusters, was sunk deep into the ley-line energy conduits! On the device's surface, crimson countdown digits flowed like fresh blood: 【00:07:23】! It was the Doctor's Seed of Annihilation!

The Seed of Annihilation was like a greedy parasite; countless purplish-black energy tendrils reached out from the crystal heart, stabbing deep into the gaps between the Sanctuary Core's geometric solids, madly siphoning Order energy while simultaneously pumping the cold corruption of rot back in! With every pulse, the Sanctuary Core's azure light dimmed a fraction more, and the fissures spread a fraction more!

"That's it!" Wrench shrieked, pointing at the Seed of Annihilation. "The countdown source! It's draining the Sanctuary Core dry!"

"Destroy it!" A cold light exploded in Lin Mo's eyes as he swung his war-blade and surged forward!

Hum—!

The instant Lin Mo stepped into the spherical space, dozens of dim-purple energy nodes flared to life across the four walls! The nodes linked in an instant, forming a colossal energy network that blanketed the entire space! Countless condensed purplish-black energy beams, like spears of judgment, lanced in from every direction! The beams carried intense corrosive rot and spiritual shock, aimed straight at Lin Mo! It was a preset automatic defense trap of the Doctor's—【Corruption Judgment Matrix】!

"Careful!" Sister Ai Li barked sharply, enduring the agony, and slammed her hands together before her!

"Moonlight—Thorn Bulwark!"

A thick shield of thorned moonlight instantly condensed before the two of them! But the purplish-black energy beams were far more powerful than imagined! The beams slammed into the light-shield, erupting with a shrill sound of annihilation! The shield shuddered violently, the thorn-runes flowing across its surface rapidly dimming and collapsing! Sister Ai Li grunted; the purple tumor on her left arm pulsed madly, a wisp of dark-purple aura snaking back up along the moonlight force, forcing a trickle of black blood from the corner of her mouth! The shield teetered on the brink of collapse!

"Wrench! Jam the synchronization of its nodes!" Lin Mo roared, simultaneously driving the "Ley Line Arbiter" viciously into the metal floor beneath him! "Heart of Thorns—Root Spike!"

Dark-gold thorn roots burst through the solid alloy floor, bearing the force of tearing all before them, and slammed hard into the walls of the spherical space, aimed straight at those dim-purple energy nodes! Yet, a flowing purplish-black energy membrane instantly materialized on the wall's surface! The roots struck it with a muffled, thunderous crash; the rock armor was rapidly corroded, the wooden spikes snapped, and they could not advance an inch!

Wrench fumbled frantically with the probe, releasing chaotic energy noise in an attempt to jam the matrix nodes: "It's no good, boss! This damn matrix's energy level's too high! My noise isn't even enough to scratch an itch!"

【00:05:48】 The countdown ticked on mercilessly. The Seed of Annihilation siphoned energy even faster; the Sanctuary Core's wailing fluctuations came through clearly! The Corruption Judgment Matrix's attack beams grew ever denser! Sister Ai Li's Thorn Bulwark was webbed with cracks, about to collapse at any moment!

"There's only… that one thing left…" Sister Ai Li's voice carried a frail, desperate resolve; silver light blazed in her eyes to the extreme, even overwhelming the purple aura churning deep in her pupils! She abruptly withdrew the hands sustaining the bulwark, letting the last few energy beams graze past her, leaving deep corrosive scorch marks on her thorn-steel armor! Her hands crossed rapidly before her chest, forming an extraordinarily complex seal with an ancient cadence, and the silver scar on her chest erupted with an unprecedented, fierce silver radiance like a small moon!

"By the moon as guide, by thorns as cage… bind! Silver Moon Vortex!"

She thrust both hands forward sharply!

Hum——!!!

A tiny silver point of light, radiating terrifying suction, instantly formed before her palms! The point spun and swelled at breakneck speed, and in the blink of an eye transformed into a silver vortex several meters in diameter, woven from countless high-speed rotating thorn-shaped moonlight filaments! At the vortex's center was absolute darkness, radiating a purifying cold that froze the soul!

A tremendous suction force erupted suddenly! The purplish-black energy beams shooting at the two were seized as if by an invisible hand, their trajectories forcibly twisted, and were dragged one after another into the spinning silver vortex! Within the vortex, the beams were torn apart and annihilated by the violent purifying force and the thorn-slaughtering power! The entire Corruption Judgment Matrix's attack stalled!

But the price was enormous! Sister Ai Li's arms, sustaining the vortex, trembled violently; the purplish-black veins beneath her skin surged upward like boiling water, instantly corroding up to her neck! Her face was paper-white; threads of blood tinged with purple aura seeped from every orifice! The tumor on her left arm pulsed even more wildly, nearly bursting from her body! She was burning her life and will, fighting the backlash of the pollution within her, forcibly wielding this power beyond her limits!

"Sister Ai Li!" Lin Mo's eyes nearly split with fury! The chance would vanish in an instant! He hesitated no longer; seizing the moment the Judgment Matrix was held in check by the Silver Moon Vortex, he poured his full will and power into the "Ley Line Arbiter"! On the sword-guard emblem, the earthen-yellow halo representing the Thorn Will blazed brighter than ever, briefly overwhelming even the azure light of the Order's Anchor! He reached into the slumbering power deep within the ley lines and let out a roar of guardianship!

"Ley Line—Arbiter!"

Gripping the sword in both hands, he slashed viciously down at the core of the Seed of Annihilation, rooted in the ley-line conduits!

A dark-gold sword aura, condensed to the extreme and mingled with Earth's Heaviness and the thorn's keen edge, tore through the viscous air, ignored the distance of space, and struck in an instant!

BOOM——!!!

Amid the deafening explosion, the purplish-black crystal heart of the Seed of Annihilation was struck precisely by the sword aura! Countless purplish-black crystal shards sprayed in all directions like a rainstorm! A shriek like shattering glass came from the core! The crimson countdown froze instantly at 【00:03:01】, then went completely dark!

Success!

However, the instant the Seed of Annihilation was destroyed—

Pfft!

Sister Ai Li, sustaining the Silver Moon Vortex, could hold on no longer; she vomited a mouthful of purplish-black blood mingled with chunks of internal organs, and the vortex instantly collapsed! She flew backward like a kite with its string cut; the bandages on her left arm completely burst apart, exposing that dark-purple tumor to the air, pulsing wildly, its surface splitting with fine fissures and emanating a sickening stench of rot! The purplish-black veins had already crawled over half her face!

"Sister Ai Li!" Lin Mo's spirit jolted violently; forcibly steadying the backlash tremors of his sword aura, he lunged toward her!

But an even more terrifying mutation came from himself!

Hum——!!!

The sleeve of his right arm exploded! The Dark Purple Mark, suppressed by the Order's Anchor, under the impact of the purest essence of rot unleashed in the Seed of Annihilation's final moment of destruction, blazed like flames doused with hot oil, instantly shattering every restraint! Violent dark-purple energy, like floodwaters breaching a dam, surged madly along his right arm's meridians toward his entire body! The cold, chaotic will of rot, brimming with endless hunger to devour, completely drowned Lin Mo's consciousness!

"Gaaaaah——!!!"

Lin Mo let out a roar that no longer sounded human! His eyes were instantly filled with dark purple! On the sword-guard emblem of the "Ley Line Arbiter" in his hands, the dark-purple light surged, completely devouring the other three colors! Wild thorn roots burst uncontrollably from the ground around him, no longer the gold of guardianship, but corrupted thorns coated in a sticky purplish-black fungal mat! They whipped madly at everything around them, battering deep dents into the alloy walls!

The azure light of the Order's Anchor flickered frantically in the depths of his soul, like a candle in the wind, battered by the violent purple tide until it was on the verge of going out! The Thorn Will wailed in agony under the erosion of the corrupt energy, nearly being assimilated! Lin Mo's body had become a battlefield where two forces fought savagely!

"Boss!!" Wrench was scared out of his wits, clutching the probe box and retreating again and again.

At this critical, hairsbreadth moment, just as Lin Mo was about to lose control completely—

Hum…!

From the wreckage of the destroyed Seed of Annihilation, a faint point of blue light struggled free of the purplish-black bindings and shot like a meteor toward Lin Mo's brow, on the verge of collapse! It was a small fragment of core data that the Sanctuary Core had stripped off with all its might in the instant the Seed of Annihilation was destroyed!

The instant the data fragment sank into Lin Mo's brow, a broken, blurred vision of intent, carrying endless sorrow and urgency, forced its way into his mind, already flooded with the will of rot:

In the vision, it was not a cold mechanical structure, but an emerald forest shrouded in boundless withering mist (foreshadowing: the elven homeland). At the forest's center, a colossal emerald ancient tree piercing heaven and earth (the World Tree?), its core deeply pierced and parasitized by a ferocious purplish-black crystal giant tree (the Rot Claw's true body?). The ancient tree's anguished wailing became a tangible sound wave. A blurred figure radiating silver moonlight and emerald light (Priestess Liyana?) struggled to hold up a crumbling seal before the ancient tree, the figure translucent, as if it might dissipate at any moment. At the vision's end, the focus shifted to the parasitized emerald ancient tree's core, where a complex light-pattern shaped like a key, formed from pure Order energy and life-runes, flashed and vanished! At the same time, a faint but clear thought rang out in the depths of Lin Mo's soul:

【…key…taken…Rot Claw…descends…stop…fusion…otherwise…all worlds…annihilation…】

"Key"!

That keyword struck like a thunderbolt, instantly cleaving part of the rotting fog! Within Lin Mo's chaotic consciousness, the azure light of the Order's Anchor seized this fleeting clarity, mingled with the Thorn Will's final defiant roar and the tremendous shock of the "key" information delivered by the Sanctuary Core, and slammed hard into the violent will of rot!

BOOM——!

Within the consciousness-space, it was as if a nuclear explosion had occurred! Lin Mo's body shuddered violently; he vomited a mouthful of black blood, and the dark-purple light in his eyes receded like a tide, revealing pupils shot through with blood. The corrupted thorns instantly withered and dispersed. He dropped to one knee, gasping violently, drenched in cold sweat; though the mark on his right arm still burned and pulsed, it was temporarily pressed back into the depths. The azure light of the Order's Anchor had dimmed to its extreme, and the Thorn Will had also suffered grave wounds, but at last… he had temporarily regained control of his body.

He raised his head, looked at the unconscious Sister Ai Li, her entire body covered in purplish-black veins, then looked at the Sanctuary Core—the purplish-black fissures on its surface had not vanished, but had stopped spreading, and its light remained faint.

The crisis… was far from over. And the mystery of the "key," like deeper storm clouds, hung over everyone's hearts.

Just then, the probe in Wrench's hands suddenly emitted a burst of urgent alert tones. He looked down; on the screen, the life-reading for the World Tree sapling beside the ley-line fissure was skyrocketing at an extremely bizarre speed! Yet, the energy imaging returned by the scan beam showed—on the tip of that withered sapling, on the surface of the newly sprouted emerald buds, wisps and threads of… dark-gold eerie patterns were silently appearing!
