The Iterator

The carpet was old, its pile worn, its colors faded, dotted with stains of unknown origin. The cheap plastic phone lay on it, its screen already dark, like a silent gray tombstone.

"All right, mentor."

"I'll be more careful next time."

Speaking into the empty air, I softly repeated what I had just said. My voice sounded hollow in the silent room.

All right. Be careful. Technological iteration.

Each word was like a cold pebble dropped into a bottomless, freezing pool, raising not a single ripple, only an endless chill sinking ever deeper.

Did he hear me? Probably not. But that didn't matter. What mattered was that I had said it. What mattered was that I knew.

I knew he was still there. I knew he was still cross-checking. I knew he was scanning every insignificant flaw like a tireless machine, drawing his pitiful, pathetic sense of superiority from them.

Technological iteration.

So he wasn't omnipotent. He had to rely on existing technological systems. A service provider's algorithm upgrades could leave him behind. His information could lag, too.

That was a weakness. A tiny weakness, but a real one.

Ryuk finally stirred in the corner. He discarded the shriveled apple core, rubbing his bony fingers together in the shadows with a faint rustle. He didn't look at me. His crimson eyes fixed on some point in empty space.

"Iteration..." he murmured hoarsely, as though chewing on the unfamiliar word. "You humans love coming up with troublesome words. If an apple's rotten, it's rotten. Eat the good parts and throw away the bad ones. Isn't that enough? You just have to study why it rots, how to make it rot more slowly... boring."

The wild laughter and astonishment were gone from his voice, leaving only pure, indifferent confusion.

I ignored him. My gaze returned to the screen. Zheng Guodong's death was like a drop of water hitting boiling oil, sending splashes everywhere. Academia, the legal world, public discourse... every voice was screaming, arguing, tearing at the others. The truth was too naked, too horrifying, and many chose not to believe it, denouncing this as yet another carefully orchestrated smear campaign and murder targeting an "upright scholar."

Chaos. Absolute chaos.

This was exactly what I wanted.

And what he feared.

The next target. I had to exploit this chaos. While all the noise distracted him, while he exhausted himself "cross-checking" information whose truth was impossible to distinguish from falsehood, I had to carry out a genuine "iteration."

A judgment he couldn't comprehend through his existing rules and knowledge.

The target had to be a mystery himself. Someone who skirted the boundaries of existing law and morality, who couldn't easily be defined as "good" or "evil," yet whose very existence created enormous injustice. His death shouldn't provide "truth" or "evidence." That would fall within the scope of his cross-checking. It should leave only... a huge, unsettling question mark.

My fingers flew over the keyboard, filtering the stranger names and incidents surfacing amid the chaos. Backroom manipulation of financial derivatives? Ethical black holes in gene-editing technology? The monopolization and manipulation of information algorithms?

Found him.

"Prophet." Not a real name, but a codename. The chief algorithm designer for a leading quantitative trading fund, and the hidden force behind several major online public-opinion incidents. His algorithms could not only reap profits from financial markets but precisely guide-even manufacture-public sentiment, buying and selling opinion like futures. The fates of countless companies, even small nations, were silently decided in the code he typed. No law could judge him, because he remained hidden behind layer upon layer of technological barriers. His "crimes" were abstract and intangible.

A true modern demon, hidden in code.

His death should be as... abstract as his existence. Just as incomprehensible.

I opened the notebook. My pen hovered.

His real name? Unknown. His face? Never made public. Only a codename and a pile of cold performance data.

But that wouldn't stop me.

The rules of the Death Note were far more... flexible than human law.

["Prophet"] (his consciousness is deeply bound to the core algorithm ["Pandora"]; they are considered a single life-form)

Cause of death: logical trap. Time: precisely nine tomorrow morning, the instant the New York Stock Exchange opens. Cause of death: the core trading algorithm ["Pandora"], on which his survival depends, will suddenly enter an irreversible self-referential loop, overwriting and deleting itself within one millionth of a second while triggering a chain of instantaneous flash crashes across seventeen major trading markets worldwide. Before death (in the final nanosecond before the algorithm collapses), it must output a line of garbled text across the public information feeds of all networked devices (including major exchange announcement screens, news notification terminals, and public interfaces on social platforms): [//Error: Truth_Is_Too_Expensive_to_Compute//]

No blood, no corpse, no last words.

Only a line of error code and a financial earthquake sweeping the globe.

Would this count as technological iteration, mentor?

The next morning.

Eight fifty-nine.

The global financial markets were calm.

Nine sharp.

The New York Stock Exchange. The opening bell had barely finished ringing.

The Dow Jones Index curve plunged as though an invisible giant hand had seized it and snapped it downward! This wasn't a decline. It was a sheer, vertical plunge into destruction!

Within three tenths of a second. London. Tokyo. Hong Kong. Shanghai... the core indices of seventeen major trading markets worldwide flash-crashed simultaneously! The scale was staggering!

Trading-halt alarms rang through every trading floor like apocalyptic wails.

At the same moment!

Every exchange announcement screen, the breaking-news pages of major news websites, even the giant billboards in some public squares were simultaneously overwritten by the same line of bizarre, distorted gibberish!

[//Error: Truth_Is_Too_Expensive_to_Compute//]

Chaos. No longer the chaos of public discourse, but the most tangible panic and chaos, smashing directly into everyone's wallets!

In my room, the screen showed the global financial markets awash in glaring blood-red, with countless alarm icons flashing wildly.

Ryuk shot to his feet, his enormous body almost filling the entire corner. He made no sound now. For the first time, his crimson eyes widened as far as they could, reflecting the destructive numbers constantly flickering on the screen, and that cold line of gibberish.

Was he... trembling?

The phone rang.

Amid the apocalyptic scene, it took a full ten minutes before it rang.

The ringtone was extraordinarily strange: an intermittent crackling, as though the signal were suffering severe interference.

I answered.

No electronic voice.

No breathing.

Only a... deeply suppressed, faint yet piercing sound of metal scraping, as though some precision instrument were overloaded and its internal structure was breaking apart.

Crackle... hiss...

The sound continued for nearly a minute.

Then came a deathly silence.

Then, at last, the electronic voice spoke.

No longer steady. No longer cold.

Instead, it was... dry, distorted, as though every byte were struggling to force its way out of a throat.

"...Unable..."

"To cross-check..."

The voice cut out briefly, leaving only crackling static.

Then, as though exhausting the last of its energy, it added a final few words with immense difficulty.

"...Iteration..."

"Effective."

The call was abruptly cut off.

A busy tone.

Shorter and more hurried than ever before.

I slowly bent down and picked the phone up from the carpet.

The screen remained dark.

I raised it to my ear and listened to the hollow busy tone.

The corners of my mouth slowly curved into a smile without a trace of warmth.

Effective.

Mentor.
