Traces of The Sovereign Sin

Chapter 1: The Last Breath

The Abyss of Mourning was a maw of shadows that didn’t just eat light—it chewed on hope. At the bottom, amidst the pile of shattered bones and the stench of ancient rot, a finger twitched.

"Breathe. Just... one more."

A wet, ragged sound escaped Kael’s throat. Each gasp felt like swallowing broken glass. His chest didn't rise; it sputtered.

"Damn it... move. Come on, Kael. Move."

He tried to push himself up. His left arm collapsed, a sickening crunch echoing against the cavern walls.

"Arggh! Son of a...!"

He rolled onto his back, staring into the oppressive void above. He couldn't see the top of the cliff. It was a one-way trip for the unwanted.

"So this is it? The Pure Cloud Sect’s final gift to their 'most loyal' disciple?"

A memory flickered, burning brighter than his current pain. The sun had been high. The air was fresh with the scent of pine. And Elder Wu’s hand was firm on his shoulder.

"You’ve done well, Kael," the Elder had whispered.

"I only did what the Sect required, Elder," Kael had replied, bowing his head. "The corruption in the granary... it's gone. The ledgers are fixed."

"Yes. Fixed. Along with your fate."

"Elder? What do you—"

"You found things you weren't meant to see, boy."

Kael’s eyes narrowed in the dark of the abyss. He could still feel the shove. The sudden, terrifying loss of gravity. The laughter from the disciples at the rim.

"The Sect is pure, Kael! We don’t need pests like you pointing out the stains!" Disciple Chen had screamed, his face a mask of sadistic joy.

"Die in the hole where you belong, traitor!"

The memory faded into a coughing fit that sprayed crimson across the gray stone.

"Traitor... I did everything for them. Everything."

He reached out blindly, his hand scraping against a surface that felt colder than ice. It wasn't stone. It was smooth. Polished.

"What is this...?"

[Searching for Host... Correlation found.]

Kael froze. The voice didn't come from the cavern. It rang inside his skull like a tuning fork made of ice.

"Who’s there? Chen? If you’ve come to finish me, show your face!"

[Scan complete. Pulse: 22 BPM. Organ failure: 88%. Probability of survival: 0.02%.]

"Who the hell are you? A ghost? A demon?"

[I am neither. I am the Sin Cultivation System.]

"A system? Like the legends of the Old Emperors? Don't make me laugh. I’m dying. Leave me alone."

[Host refusal noted. Initiating terminal countdown. Ten. Nine...]

"Wait! Stop! What do you want?"

[I want your resentment. Your anger. Your sins.]

"Why would you want that? Is this some joke?"

[Six. Five...]

"Fine! Do whatever you want! If I'm going to die, I might as well die screaming at a voice in my head!"

[Warning: Direct contact with the Sovereign Altar required to bridge the Soul Gap.]

Kael looked down. His hand was resting on a black, obsidian-like pedestal covered in glowing, jagged runes. They were hungry, pulsing with every drop of blood that leaked from his palm.

"This altar... did I fall on a grave?"

[You fell on the Heart of the Sovereign. Blood confirmed. Resentment levels: Overwhelming. Condition met.]

The altar beneath him shivered. The ground groaned as if a giant were waking up.

"What's happening? It’s... it’s warm. The pain is..."

[The Altar is feeding. It takes your blood to give you power. Do you accept the path of the Sinner?]

"I don't care about the path. I just want them to pay. Wu... Chen... every single one of those hypocrites."

[Anger confirmed. Integrating Sin Cultivation core.]

Suddenly, white-hot needles stabbed into his brain. Kael shrieked, his back arching, bones popping into place with violent speed.

"AHHHHHH! Stop it! My head is—!"

[Rewiring Meridians. Purging Orthodox Qi. Replacing with Sin-Infused Essence.]

"Orthodox Qi... gone? That was my foundation! Seven years of cultivation... gone just like that?"

[It was garbage. Weak. Built on lies. Sin Qi is pure. Destructive.]

Kael felt his strength returning. He sat up, watching in shock as the jagged cuts on his arms sealed themselves, leaving thin, black scars.

"This is impossible. My ribs were powder five minutes ago."

[Energy levels stabilized. Welcome, Kael. You are currently at Rank 0: Disciple of Malice.]

"Disciple of Malice... sounds like a villain."

[To those who hide their filth in light, the truth always looks like a villain.]

Kael gripped his broken sword. The blade was snapped halfway, but he felt a strange connection to it now. It felt heavier. Meaningful.

"Alright, 'System'. If this isn't a dream, how do I get out? How do I get to them?"

[The Abyss is not a prison for those who know how to climb using the blood of their enemies.]

"There are no enemies here. Just me and a pile of bones."

[Behind you. The Shadow Wolves have sensed the Altar's pulse. They are hungry.]

Kael spun around. Dozens of glowing red eyes emerged from the darkness. The growling was low, a vibration in the ground that made his teeth ache.

"Wolves... great. More things trying to eat me."

[Current power insufficient for prolonged combat. Recommendation: Utilize 'Wrath' burst.]

"How? Just tell me how!"

[Scream. Release the hatred you felt when they pushed you. Don't hold it. Use it.]

The first wolf lunged—a blur of fur and fangs. Kael didn't think. He didn't use a sect form. He just lashed out.

"DIE!"

A wave of purple energy exploded from his hand. It hit the wolf mid-air, not just throwing it back, but disintegrating the flesh from its chest. The creature didn't even have time to howl before it was a pile of charred remains.

"Did I... did I just do that?"

[First Sin manifested: Wrath. Cultivation point +50. Bonus for the first kill: Triple Reward.]

"I feel... powerful. Stronger than I ever was at the Pure Cloud."

[That was only a taste. Wrath is a drug. Use it too much, and it will burn your mind. You need balance.]

The other wolves hesitated, circling him. They weren't just predators now; they were afraid.

"They should be afraid. Everyone should be."

[Warning: Host's body temperature is rising. Internal pressure exceeds safety limits.]

"It’s too hot. It feels like my blood is boiling. Help me!"

[Wrath requires a coolant. Vitality. Emotional depth. Lust.]

"Lust? You want me to find a woman in a cave full of skeletons? Are you insane?"

[Scanning nearby coordinates... Detection complete. Life signature found in the Inner Trench. Rank: Unknown. Sin Signature: Pure Lust.]

"Someone else is down here? Alive?"

[A vessel. High compatibility with your Sovereign Core. Move now, Host. Before the fire consumes your meridians.]

Kael stumbled forward, his vision blurring with a red tint. He wasn't walking; he was being driven by an instinct older than his sect.

"Where is she? Tell me!"

[Thirty meters. Behind the sealed slab. Her name is recorded in the annals of history, but the world has forgotten her. Do you wish to proceed?]

"If it stops this burning, I’d march into hell."

[You are already in hell, Kael. I’m just giving you the keys.]

Kael reached a massive stone wall covered in vines of iron. He didn't look for a keyhole. He just raised his hand, gathering every ounce of that boiling, hateful energy.

"Break!"

The slab shattered into a thousand pieces. Dust clouded the air. Kael stepped through, coughing as his heat-sensitized skin felt a sudden, freezing chill.

"What is this place? A tomb?"

[A prison.]

In the center of the chamber, illuminated by a pale, blue lichen, sat a figure. She was bound by chains made of white light, her head bowed, her long, violet hair spilling over her shoulders like silk.

"A woman?"

[The Vessel of Lust. Lyra. Fallen Empress. Do not be fooled by her beauty; she is the first key to your throne.]

Kael approached, his footsteps heavy. He could barely breathe. The heat in his chest was becoming unbearable.

"Hey... can you hear me?"

The woman's head tilted up. Her eyes were an electric shade of violet, sharp enough to cut through the dark. She didn't look scared. She looked... bored.

"A boy?" Her voice was like honey dripping over a blade. "Did the Orthodox bastards finally run out of executioners? Did they send a child to watch me rot?"

"I’m not... I’m not with them. They threw me down here to die."

Lyra’s gaze raked over his shaking form. Her nostrils flared slightly.

"You smell of it," she whispered, her chains rattling as she leaned forward. "Wrath. But it’s messy. Untrained. It’s burning you alive, isn’t it?"

"I... help me."

"Help you? Why? Give me one reason why I shouldn't watch you melt into a puddle of angry grease."

[Mission: Establish Contract. Reward: [Lust Core] Activation. Path: Survival.]

"Because," Kael growled, forcing himself to look into her eyes, "If I die, you stay in those chains forever. But if I live... I’m going to tear that Sect down stone by stone."

Lyra stared at him for a long, silent beat. Then, she laughed. It was a cold, beautiful sound.

"Ambition. In a dying boy. How refreshing."

"Touch me," he gasped, falling to his knees in front of her. "The voice said... contact. To balance the energy."

"The voice? You have the mark, don't you?" She reached out as far as her chains would allow. Her fingers were inches from his forehead.

"Are you ready, boy? Once we link, there’s no turning back. You won’t just be a disciple anymore. You’ll be a monster."

"I was a man who tried to be good, and it got me pushed off a cliff," Kael said, his voice dropping into a rasping growl. "Make me a monster. Make me anything, as long as I can see their faces when I return."

Lyra smiled, showing a flash of white teeth.

"Choose your Sin, Sovereign. The game has just begun."

[Emergency Prompt: Initializing 'Contract of the Blood Moon'. Option A: [Lust] Integration. Option B: [Death] by Overload.]

"Lust," Kael choked out. "Do it!"

The system screen in front of his eyes flared to life.

[Processing Choice... Integration: 1%... 5%... 10%...]

Lyra’s hand slammed onto the back of Kael’s neck, pulling him closer. The contact was an instant explosion. It wasn't just heat. It was a flood of memories, power, and a strange, intoxicating vitality that surged into his empty veins.
