Rain had fallen the night before.
The earth under the old banyan tree was soft, black, and smelled of worms and wet stone. The tree itself was a giant, its branches a gnarled cathedral, roots breaking through the school's back wall like stone fingers. It was a place for secrets. For things adults never saw.
Seven children stood in a rough circle. The air was cold. Their breath made ghosts. A persistent mosquito whined near Long Jin's ear. He ignored it.
He held the knife.
It wasn't the obsidian sliver. This was a simple pocket knife. Wang Lei's. Its blade was dull, speckled with rust. It felt heavy in his six year old hand.
This was his idea.
The Circle was still just a concept. A fragile alliance of convenience and childhood loyalty. It needed cement. Something stronger than a promise. Something that would linger in the blood and the memory.
A ritual.
"This is stupid," Liang Wei mumbled, shifting his feet. He kicked a pebble. It skittered into the roots. "I mean, what if it gets infected?"
"It's not stupid," Wang Lei said, his voice firm. He stood tallest, a bulwark against the world. "It's how brothers are made. In movies."
"We're not brothers," Fang Jie observed quietly, his sharp eyes missing nothing. He pushed his glasses up his nose.
"We will be," Long Jin said. The wool of his sweater collar was damp and itchy against his neck. "After today."
The system was silent. Watching. Analyzing this non economic, non strategic expenditure of time and social energy.
[Social bonding ritual detected. Primitive. Emotional utility: unquantified. Proceed?]
He ignored it.
He opened the knife. The click was loud in the quiet grove. The mechanism was stiff.
"We each cut," he said, his voice sounding too old, too sure for his body. "One palm. We mix the blood. We swear."
Chen Bo, the dreamer, looked queasy. "Will it hurt? Like, a lot, or just a bit?"
"Yes," Xiao Ming said, the artist. He was already imagining the composition. The red against the green. The solemn faces. "It has to hurt. Or it doesn't count. That's the rule."
Ma Yong, the quiet one, just nodded. He sniffled. He had a slight cold. He offered his hand first.
Long Jin took it. The boy's palm was calloused already from carrying things. From hard work.
He pressed the blade. Not deep. A quick, sharp sting. A red line welled up.
Ma Yong didn't flinch. He just watched the blood bead, his expression thoughtful.
One by one, they came.
Wang Lei, grimacing not from pain but from the intensity of his own feeling. He held his hand out like a soldier.
Zhang Hao, calculating the optimal depth for symbolism versus healing time. He adjusted his hand at the last second.
Chen Bo, shutting his eyes tight. He turned his head away.
Xiao Ming, watching the blood with fascination. He said, "The color is brighter than I thought."
Liang Wei, making a joke that died on his lips as the metal bit. He hissed through his teeth.
Fang Jie, his gaze locked on Long Jin's face, as if reading the future in his eyes. He didn't blink.
Last, Long Jin cut his own palm. A familiar sensation. Pain was just data. But this pain meant something else. It was an anchor. The cut was slightly crooked.
They pressed their palms together. A clumsy, seven pointed star of stinging flesh and warm blood. Chen Bo's hand was trembling. Wang Lei's was rock steady.
It dripped onto the roots of the old tree. The dark wood drank it in.
"Swear," Long Jin commanded.
They spoke over each other. A chaotic chorus of childhood loyalty.
"Never tell secrets!"
"Always share food! Except if it's the last candy, then maybe..."
"Fight each other's fights!"
"Protect the weak!"
"Stay friends forever! No matter what!"
The words hung in the damp air. Silly. Profound.
Then, in the silence that followed, Wang Lei added, his voice low and gruff, "Family. No matter what happens."
That was the one. The core vow.
Family. No matter what.
The system chimed then. A soft, surprised sound in his mind.
[Alliance formalized. Emotional Capital: +350. Bond designation: 'Blood Oath - Primitive Tier'. Durability: high. Future betrayal penalty: catastrophic.]
The green text glowed. It had quantified the unquantifiable. It had turned their bleeding palms into a ledger entry.
Long Jin felt a chill that had nothing to do with the weather. The mosquito finally bit his neck. He slapped at it, leaving a smudge of his own blood.
He had wanted a bond. He had created a liability.
The memory was a knife twist.
Now.
Long Jin stood under the same tree. Alone. He was sixteen. A decade of life lived in the space between that oath and this silence.
The rain was the same. The smell was the same. The mosquito was probably a descendant.
But the Circle was gone.
Wang Lei was in a juvenile detention center, taking the fall for a decoy empire.
Chen Bo was in the south, bitter and confused.
Xiao Ming was chasing social status, his art forgotten.
Liang Wei was drinking away his father's legacy.
Zhang Hao was a strategist without a board, hiding with his family.
Fang Jie was a silent observer of the ruin.
Ma Yong was dying quietly in a hospital, saying nothing.
The blood oath had not saved them. The +350 Emotional Capital had been spent, withdrawn, and was now deep in the red.
The system displayed the current tally.
[Emotional Capital: -682. Status: Default. Blood Oath Contract: breached by multiple parties. Penalty: ongoing.]
He placed his hand on the rough bark. Where their blood had fallen, a dark stain was still visible. A faint, rusty shadow swallowed by moss and time. A beer bottle cap was wedged in a crevice nearby.
He had come here for a reason. Not for nostalgia. For a tactical assessment.
The oath was a vulnerability. A point of emotional leverage the Zhou family could exploit. They knew about the Circle. They would seek to use its broken pieces against him.
He needed to neutralize it. To close the ledger.
But you can't close a ledger with a balance that negative. You can only settle it.
Li Mei found him there. She didn't ask why he'd come. She saw the tree. She understood. Her boots splashed in a shallow puddle as she approached.
"You're auditing the damage," she said, leaning against the opposite side of the massive trunk. She picked at a piece of lichen. It came away in a dry, crumbling sheet.
"I'm calculating the remaining risk."
"The risk is you." She flicked the lichen away. "This tree. This oath. It's your original sin. The moment you tried to force a human feeling into a system's framework. You gave it a number. Of course it broke."
"It was supposed to make it stronger." His voice was flat. "A quantifiable bond."
"You can't strengthen a rope by assigning it a tensile strength rating." Her voice was tired. "You just start noticing when it begins to fray. And you cut it before it fails. Or it fails anyway."
He looked at his palm. The scar was a faint white line now. Almost invisible. It itched sometimes when it rained.
"They'll come for them," he said. "One by one. To get to me."
"Yes."
"I have to protect them."
"You can't." She pushed off the tree. "You chose the fortress strategy. One core asset. The rest is expendable. You sacrificed Wang Lei to that logic. Can you un sacrifice the others?"
The question was a trap. And the answer was a wound.
"No." The word was final.
"Then your only move is to make them worthless as leverage." She stepped closer, the rain misting her hair. "You have to sever the tie. Publicly. Brutally. Make it clear they mean nothing to you. That the oath is dead."
He stared at her. "You're telling me to betray them first."
"I'm telling you to release them." Her eyes were fierce. "The oath is a chain. On you. On them. As long as it exists, Zhou can use it. Cut the chain. Let them go. It's the only protection you have left to give."
The moral ledger pulsed. A sick, green wave.
[Proposed action: Strategic severance of primary social bonds. Moral debt projection: +100. Emotional Capital reset possible. Survival probability increase: significant.]
A hundred points of debt. To save them.
To become the monster they already thought he was.
"How?" he whispered. His throat was tight.
"You know how." She turned away, her shoulders a hard line. "You're the calculator. Find the most efficient path. Even if it... even if it feels like cutting off your own hand."
The path was a newspaper.
Two days later, a small article appeared in the business section of The Metropolitan Daily. Page six. Easily missed. It was next to an ad for discount office furniture.
'Reclusive Young Investor Severs Ties with Past Associates'
It was three paragraphs. Dry. Legalistic. Badly typeset in one spot.
It stated that Long Jin, through his legal representatives, formally disavowed any and all ongoing business or personal relationships with a list of named individuals. Wang Lei. Chen Bo. Xiao Ming. Liang Wei. Zhang Hao. Fang Jie. Ma Yong.
It cited "irreconcilable differences" and "a divergence of commercial ethics."
It was a lie. It was a masterpiece.
He had used the last clean channel to Feng to place it. A favor called in. No trace back to him.
The article was a scalpel. Cutting the thread of the blood oath in the most public, most humiliating way possible.
It didn't just say they weren't friends. It said they were ethically compromised. It painted them as liabilities. It made them toxic.
To the Zhou family, they were now worthless. Damaged goods. No leverage.
To the Circle, it was the ultimate betrayal.
He sat in the empty apartment he kept for meetings. The one with no personal items. A shell. The window had a crack in the corner, making the view of the rain washed street warp slightly.
He watched the rain streak the window.
The system updated in real time.
[Public disavowal broadcast complete. Zhou surveillance protocols indicate shift: subject associates downgraded to 'non essential'. Threat reduction: confirmed.]
[Emotional Capital reset to: 0. Blood Oath Contract: officially nullified.]
[Moral Debt incurred: +102. New balance: 148.]
A hundred and forty eight. The number sat in his gut like a cold stone.
He had traded their loyalty for their safety. He had paid for their freedom with a piece of his own soul.
He wondered if they would understand. He knew they wouldn't. Not at first. Maybe not ever.
The reactions came. As whispers. As wounds.
Chen Bo's father called his parents, screaming about libel, his voice crackling down the poor connection. His mother cried on the phone to Long Jin's mother, her voice broken. "What did we do? What did my boy do to deserve this... this public shame?"
Xiao Ming's new, social climbing friends dropped him immediately. The article was a social death sentence. He was now "that kid who got called unethical by the phantom whiz kid." He was overheard at a cafe, his voice rising in a shaky defense that trailed off into silence.
Liang Wei got drunker. He was reported for a fight at a bar. He used Long Jin's name. It meant nothing now. It made him look more pathetic. He was heard muttering, "He said family, he said no matter what, and then he just..." before his words slurred into incoherence.
Zhang Hao sent no word. His silence was the loudest rebuke. The strategist would see the move for what it was. And he would hate it. Because it was right. Because it was cold. Because it worked.
Fang Jie, the observer, simply vanished. No one knew where he went. He was the first to truly disappear. His father told neighbors he'd gone to study abroad. The neighbors didn't believe it.
Ma Yong's sister came to the door. She didn't yell. She just stood there, her eyes hollow with grief and fury. She spat on the doorstep. A small, wet sound. Then left.
Wang Lei, in his cell, heard through the grapevine. His response was to get into a fight with a bigger inmate. He won. He sent no message. The guard reported he was quieter afterwards.
The Circle was not just broken. It was erased. Denounced.
The blood under the old tree was just a stain now. A forgotten mistake.
Michael Zhou's response was a single sentence, delivered via a postcard. A generic cityscape of a place Long Jin had never been. The message on the back was typed.
'Clever. Ruthless. You learn fast.'
It wasn't a compliment. It was an acknowledgment. A predator recognizing a new predator's tactics.
Long Jin burned the postcard over the kitchen sink. The plastic coating melted and bubbled, giving off a foul smell.
The game had changed. He was no longer a specimen to be studied. He was a rival to be contained.
And he was alone.
Truly alone.
Li Mei was still there. But she was separate. She was the tether to humanity, not to the past. She watched him with new eyes. Sad eyes. She had given him the knife. She had watched him cut.
She didn't apologize. Neither did he. They ate dinner in a silence that was no longer comfortable. The rice was slightly undercooked.
He went back to the tree one last time.
Night. No rain. A cold, clear sky. The moon was a thin sliver.
He took the rusty pocket knife from his own pocket. Wang Lei's knife. He'd kept it all these years. The hinge was even stiffer now.
He found their names. Carved clumsily into the bark a week after the oath. A child's permanence.
WANG. CHEN. XIAO. LIANG. ZHANG. FANG. MA. JIN.
He took the knife. He scraped his own name out first. The wood was soft underneath. He dug until the letters were a raw, ugly gash. Splinters stuck to his fingers.
Then, one by one, he scraped out the others. The knife slipped once, nicking the 'G' in Zhang. He kept going.
He didn't stop until the bark was a mess of scars. Unreadable. A monument to nothing. His palm ached from the pressure.
The system was silent. No debt was added. No capital was lost. It displayed only the ambient temperature and the time.
Some acts were beyond its calculus.
He dropped the knife at the base of the tree. It landed in the wet leaves with a soft thud. Let it rust. Let it return to the earth.
He walked away and did not look back.
The oath was dead.
The fortress was complete.
He walked for blocks, his hands in his pockets. The city around him was a blur of light and shadow. He passed a late night noodle stand, the steam rising in a fragrant cloud. He didn't stop.
When he finally got home, he stood at the sink and washed his hands. The water was very hot. He scrubbed at the dark grime and tiny splinters embedded around the old, faint scar on his palm.
He scrubbed until the skin was red and raw.
The green glow in the mirror behind him was the only light in the dark room. It lit the steam rising from the sink, making it look like ghostly, glowing breath.
He turned off the water. The silence was absolute.
He looked at his clean, empty hands. Then he turned and walked into the dark of the apartment, leaving the green light reflected in the blank eye of the mirror.
