Sin Collector Cultivator

3. Betrayal at Mount Merapi

The air at the summit of Mount Merapi was thin, tasting of sulfur and impending death. Jagged volcanic rocks clawed at the gray sky like the fingers of a buried titan.

`[Notice: Proximity to First Vessel: 50 meters.]`

`[Emotional Frequency: Crimson-Shattered. Intensity: 9.8/10.]`

`[Observation: The 'Betrayal' resonance is vibrating at a frequency high enough to cause minor spatial distortions.]`

"I can smell it," Arion whispered, his boots crunching on the black ash that dusted the mountain peak. "It smells like scorched iron and copper."

`[Correction: That is the smell of a genius bleeding out. Proceed with caution. Five 'Virtuous' auras detected ahead.]`

Arion pulled his hood lower, merging with the jagged shadows of the crags. Below him, on a wide natural ledge overlooking a sea of clouds, a drama of 'holy' treachery was unfolding.

"Is this the 'High Virtue' you were talking about, Caspian?" Lyra’s voice was a jagged blade, cutting through the whistling wind.

She was slumped against a scorched pillar, her white sect robes ruined by slashes of red. Her left arm hung limp, and a strange, pulsating violet vein crawled up her neck—the sign of 'Heart-Piercing Frost' poison.

"Don't be so dramatic, Lyra," a tall, handsome man replied, casually wiping a droplet of blood from his jade-encrusted sword. Caspian, the Prime Disciple of the Sky Sword Sect, looked every bit the legendary hero. "This isn't betrayal. This is a strategic realignment of assets."

"You... you shared my bed yesterday," Lyra hissed, coughing up a spray of dark blood. "You swore on the Ancestors' Grave that we would refine the Heavenly Core together!"

"And I meant it, at the time," Caspian laughed, a bright, melodic sound that lacked any trace of warmth. "But then the Sect Leader reminded me: a sect only needs one Sun. You’re too talented, Lyra. Your 'virtue' was making the rest of us look like dim lanterns. It was unbalancing the harmony of the sect."

"So you poisoned my tea?" she spat. "You waited until I fought off the Infernal Beast to strike me in the back?"

"The Beast provided the perfect cover," one of the younger disciples sneered, stepping forward to flank her. "The records will say the great Sword Genius Lyra died a martyr's death, sacrificing herself so that Brother Caspian could secure the relic for the sect’s glory. We’ll even build a shrine for you. Think of the karma you’ll earn in the next life!"

"You're animals," Lyra growled, her hand trembling as she tried to grip the hilt of her broken sword.

`[Target Scan: Lyra. Talent: Heaven-Grade Sword Seed. Current State: Dying. Accumulated Despair: 8,000 units.]`

`[Target Scan: Caspian. False Virtue Rating: 95. Actual Sin Value: 12,000. Quality: Highly Refined Malice disguised as Fate.]`

"System," Arion thought, his eyes narrowed. "If I kill Caspian right now, what's the payout?"

`[Extremely high. Killing a 'Golden Boy' of the Aliansi provides a massive 'Truth Shock' to the local fabric of reality. Estimated Energy Gain: 15,000 units. But warn: The Vessel’s heart is about to shatter. If she dies before the link is established, the resonance is lost.]`

"I'm not here for the loot yet," Arion whispered. "I’m here for her."

On the ledge, Caspian stepped closer, his boots making a slow, rhythmic sound on the stone. "Give me the Jade Emperor's Core, Lyra. Don't make me cut it out of your dantian while you’re still breathing. Let’s keep this 'pious'."

"Come and get it, you hypocritical dog!" Lyra screamed. She lunged, her movements blurred and desperate, but the poison took its toll. She stumbled, her sword clattering uselessly against the rock.

Caspian effortlessly parried the pathetic strike, his sword hand striking her across the face. "See? This is why I had to do this. Even poisoned, your instincts are faster than mine. It’s disgusting. It’s an affront to the natural order of birthright."

"My instincts... come from ten years... in the icy trenches!" Lyra gasped, pinned to the floor by Caspian’s foot on her shoulder. "While you were sipping spirit wine and acting the part of a prince!"

"And now, that prince is the one with the sword," Caspian smiled, raising his blade. "Goodbye, Lyra. May your next life be a little more... humble."

"Wait," Arion’s voice drifted across the ledge, cold and indifferent.

Caspian froze, his sword hovering inches from Lyra's throat. The four other disciples whirled around, drawing their weapons.

"Who’s there?" Caspian demanded, his voice dropping an octave into a defensive growl. "This is private Sect business. Begone, if you value your life!"

Arion stepped out from behind the volcanic rock. He looked small, dressed in scorched rags, his aura a complete void that the cultists’ spiritual senses couldn't even grasp.

"It’s just a mountain scavenger," the younger disciple laughed, relaxing his stance. "Hey, peasant! Did you get lost looking for herbs?"

Arion ignored him, his gaze locked on Lyra. He saw the arterial red of her betrayal swirling around her like a violent storm. "She’s dying quite beautifully, isn't she?"

"Step away, brat," Caspian warned, his eyes narrowed. "Or you’ll join her in the pyre."

"I was just looking at your karma, Caspian," Arion said, tilting his head. "It’s very... gold. Almost too gold. Like a coin that’s been polished to hide the rust."

"How do you know my name?" Caspian asked, his grip tightening on his sword. "You have no cultivation. You’re a wretch."

"Does it matter?" Arion stepped onto the ledge, his presence suddenly feeling ten times heavier. "I'm just an accountant. And by my count, you’ve racked up quite a debt today. Killing your fiance? Striking a poisoned woman? That’s a lot of 'correction' needed."

"He’s crazy," the disciple in the blue robe muttered. "I’ll handle this, Brother Caspian. Just some rogue who’s seen too much."

The disciple lunged at Arion, his sword glowing with a faint blue spiritual light. "Go to sleep, beggar!"

`[Shadow-Sin Step: Initializing.]`

In the eyes of the cultists, Arion simply flickered. He wasn't there, and then he was—inside the disciple’s guard, his hand resting gently on the man's chest.

"You really should have checked your own aura first," Arion whispered. "It’s very... hungry."

"What—?"

A muffled *boom* echoed through the ledge. A pulse of black energy erupted from Arion's palm, turning the disciple's ribcage into dust. The man didn't fly back; he simply crumpled into a heap of shrivelled skin and bones, his essence dragged into Arion’s sleeve.

`[Absorbing 300 units of Arrogance. Power level updated.]`

Caspian backed away, his face pale. "Black... black energy? Demonic cultist? I knew Oakhaven’s survivor was a plague! You’re the monster the guilds were talking about!"

"Monster? That's a funny word coming from you," Arion said, stepping over the corpse.

"Kill him! All of you! Formation Nine!" Caspian roared.

The remaining three disciples scrambled to form a triangle, their swords connecting in a web of golden spiritual light. A 'Purifying Circle' meant to incinerate dark energy.

"The Holy Light shall purge your filth!" they chanted in unison.

"System," Arion thought. "Is that light bothering you?"

`[Scanning 'Purifying Circle'... Status: Fraudulent. It is dually powered by the fear of the disciples. Would you like to use 'Void-Siphon' to bypass?]`

"No," Arion said, his eyes glowing purple. "I want them to feel their 'Holy' light turn into lead."

Arion walked straight into the golden barrier. The golden flames lashed at his skin, but instead of burning, they were dragged into the black tattoos on his wrists. The barrier flickered, the gold turning to a sickly, charred gray as Arion’s 'Correction' inverted their power.

"It’s... it's not working!" one disciple screamed, his sword beginning to smoke. "It’s drinking our qi!"

"It’s not drinking it," Arion said, his voice cold as the mountain peak. "It’s simply returning it to its true state: empty greed."

Arion moved like a reaper. Three flashes of black mist, three sickening crunches. Three more bodies were reduced to husks, their 'merit' and 'virtue' stripped and converted into pure Sin Energy.

`[Energy Gained: 2,400 units. Total Pool: 7,400.]`

Arion stood five feet from Caspian, who was shaking so hard his sword rattled against the stone.

"Wait! Wait!" Caspian stammered, holding up the Jade Emperor’s Core—a glowing green orb of immense power. "You want this, right? It's worth a fortune! Take it! Just... just let me leave! I’ll tell the Aliansi you weren't here! I'll tell them the girl did it!"

"Still negotiating with sins?" Arion asked, his voice filled with genuine disgust. "You don't get it, do you? I don't want the rock. I don't want your lies."

He turned his eyes to Lyra, who was staring up at him with a mix of terror and dying hope. "I want her."

"The... the sword girl?" Caspian gasped, confused. "She’s a corpse! She’s poisoned by a Heart-Piercing Frost! No healer in the three continents can fix that!"

"I'm not a healer," Arion said.

He stepped past the terrified Caspian and knelt beside Lyra. The red aura around her was so intense it was stinging Arion’s eyes.

"Who... what are you?" Lyra wheezed, her blood bubbling on her lips.

"Your only choice," Arion replied. "Tell me, Lyra. At this moment, looking at that man... what do you want more than life itself?"

Lyra looked at Caspian, her eyes blazing with a hatred so pure it momentarily stilled the poison in her veins. "I want... I want him... to rot. I want him to know... the cold... I feel."

"Is that all?" Arion asked, reaching out to touch the cold sweat on her forehead.

"No," she snarled, a visceral, animal sound. "I want them all to pay. The sect. The lies. Everything they call 'Holy'. I want to see it all turn to ash."

`[Core Resonance Detected. Compatibility: 99.9%.]`

`[Warning: Subject's life force at 2%. Internal poison at 98% of the heart.]`

"Good," Arion said, a ghost of a smile appearing on his lips. "That’s exactly the fuel I’m looking for."

He turned his head to look at Caspian. "She wants you to rot, Caspian. And as an accountant of the cosmos, I think your debt is finally due for collection."

"Stay back!" Caspian screamed, throwing the Jade Core at Arion like a bomb and turning to bolt toward the cliff’s edge, where a flying sword awaited him.

Arion caught the Jade Core with his left hand. The green relic instantly turned black as its spiritual essence was suffocated by his touch. With a flick of his wrist, Arion crushed the ancient relic into dust.

"Run as fast as your 'virtue' can take you," Arion said softly.

He turned back to Lyra. "You have two paths. You die here, as a martyr for a man who hates you. Or, you give me your hatred. You give me your sins. And in return, I give you the world’s end."

Lyra’s hand reached out, clawing at Arion’s cloak. "Do... it. Make me... your monster. Just... let me... kill him."

`[Vessel Candidate 1: Lyra. Contract Initiation?]`

"Initialize," Arion whispered. "Rantai Karma: First Link."

`[Protocol: Karma Chain Initiation. Processing 5,000 units of Sin Energy for Soul Grafting.]`

`[Warning: The process is... excruciating.]`

"Do it anyway," Arion said.

He grabbed Lyra’s hand, his fingers interlacing with hers. Suddenly, black smoke didn't just rise from the ground—it erupted from Arion’s chest, forming a heavy, spectral chain that hummed with a sound like a choir of the damned.

Lyra’s eyes flew open. She didn't scream; the sound was lost as the black energy surged into her, seeking out the violet poison and devouring it like a wolf devours a lamb.

In the distance, Caspian had reached his flying sword. He glanced back, seeing the mountain peak erupting in a pillar of black light that blotted out the sun.

"What... what kind of hell have I unleashed?" Caspian whispered, before plunging his sword into the clouds and fleeing for his life.

Arion ignored the fleeing man. He felt Lyra’s heart rhythm merging with his. He felt her memories—the icy training, the fake smiles of the sect, the crushing weight of Caspian's betrayal—flowing into his mind like a river of thorns.

"Drink it all, System," Arion groaned as his own skin began to crack from the pressure. "Filter it through her!"

`[First Vessel Binding... 50%... 80%... 100%.]`

`[Karma Chain Established.]`

`[Status Update: User Arion & Vessel Lyra are now linked.]`

The black light faded.

Lyra sat up, gasping for air. The violet poison was gone. Her eyes, once a clear hazel, now had flecks of violet and black swimming in the iris. On her right wrist, a jagged tattoo of a chain was burned into her skin, trailing up her arm.

She looked at her hands. They weren't cold anymore. They felt like they were made of living lightning.

Arion stood up, his face pale but his eyes burning with renewed power. "How do you feel?"

Lyra looked at Arion, then at the empty cliff where Caspian had fled. She stood up, her movement so fluid it defied the laws of the body. She picked up her broken sword. With a pulse of her new energy, the shattered steel was coated in a layer of dark, solidified shadows, making it longer and sharper than it had ever been.

"I feel," Lyra said, her voice dropping into a register that made the mountain tremble, "like I finally see the world for what it truly is."

She turned to Arion, a dark, terrible realization dawning in her gaze. "I’m yours now, aren't I?"

"In sin and blood," Arion replied, his purple eyes scanning the horizon where Caspian’s aura was still a faint, terrified flicker. "But look on the bright side. You’re the first one who gets to watch me break the heavens."

`[Mission Update: Harvest the Fleeing Sin. Distance to Target: 2 miles.]`

"Let’s not keep your 'beloved' waiting, shall we?" Arion smiled.

Lyra didn't answer with words. She simply stepped off the cliff edge, her body vanishing into the shadow-folds of the air, moving faster than any flying sword.

Arion followed.

On the peak of Mount Merapi, only ash and five shrivelled husks remained. The 'Holy' Light of the sun touched the stones, but it couldn't penetrate the silence left behind.

The first link was forged. The correction had truly begun.
