Ethan didn't blink for several seconds.
The words on the screen stayed there, unmoving.
The game is about to change.
Marcus broke the silence first.
"Okay… I officially hate that sentence."
Ethan leaned back slowly in his chair.
Across his monitors, the markets were still moving like a storm.
Helios Technologies continued climbing.
Up 4%.
Then 5%.
Then 6%.
Money was pouring into the stock from every direction.
But Ethan wasn't watching the price anymore.
He was watching the order flow.
And something inside it had changed.
"There," Ethan said suddenly.
Marcus leaned closer to his microphone.
"What?"
Ethan highlighted a cluster of trades.
Small ones.
Only a few thousand dollars each.
But they were placed with perfect timing.
Every move Ethan's AI made…
The rival system responded.
Not immediately.
Not randomly.
But strategically.
Marcus frowned.
"That can't be coincidence."
"It isn't," Ethan said quietly.
He pulled up the timestamp log.
The rival system's response time averaged 0.8 seconds.
That was absurd.
Even high-frequency trading firms struggled to react that quickly while still analyzing market conditions.
Marcus muttered under his breath.
"That's not a trader."
Ethan nodded.
"It's an AI."
The mysterious terminal flashed again.
A new message appeared.
Observation confirmed.
Marcus groaned.
"Great. The creepy market ghost agrees with you."
Ethan ignored him and typed.
Is the rival system human-controlled?
The response came almost instantly.
Unknown.
Then another line appeared.
But its learning rate is accelerating.
Ethan felt a small knot tighten in his stomach.
Accelerating meant the system wasn't just reacting.
It was improving.
Fast.
Marcus asked quietly,
"So… what happens if it figures out your strategy?"
Ethan didn't answer immediately.
Because he already knew the answer.
"If it understands my strategy…"
He looked back at the Helios chart.
"…it can destroy it."
The stock surged again.
Helios jumped another 2%.
Marcus shouted.
"Ethan! Ninety thousand!"
Ethan glanced at the balance.
$91,340.
Only a few weeks ago he had been a broke student with $214.
Now he was approaching six figures.
But the victory felt strangely hollow.
Because something else appeared on the order book.
A massive sell wall.
Marcus saw it too.
"Oh… that's big."
Ethan zoomed in.
Someone had just placed a $3 million sell order above the current price.
Marcus whistled.
"That'll stop the rally."
Ethan shook his head.
"No."
Marcus blinked.
"No?"
Ethan pointed at the order size.
"Look closely."
Marcus studied the data.
Then his eyes widened.
"Oh."
The order wasn't real.
It kept appearing…
Then disappearing.
Then appearing again.
Marcus whispered.
"That's manipulation."
Ethan nodded.
"Spoofing."
A classic trick.
Large fake orders designed to scare other traders into selling.
But something about this one felt different.
The timing was perfect.
The placement was perfect.
And it only appeared when Ethan's AI tried to buy more shares.
Marcus suddenly went quiet.
Then he said slowly,
"That thing isn't manipulating the market."
Ethan looked at the screen.
"It's manipulating you."
Another trade executed.
The rival system sold a small batch of shares.
Just enough to push the price down slightly.
Then it waited.
Ethan's AI detected the dip and tried to buy more.
And instantly—
The giant sell wall appeared again.
The price dropped.
Marcus cursed.
"It's baiting your algorithm!"
Ethan's heart rate increased.
Because Marcus was right.
The rival system had discovered something important.
It had learned how Ethan's AI thought.
The terminal flashed again.
Adaptive strategy detected.
Ethan typed quickly.
The rival system is targeting my algorithm.
The response came instantly.
Correct.
Another line appeared.
It is learning from you.
Marcus muttered,
"This is getting out of control."
Ethan stared at the rival trades.
Small.
Precise.
Testing.
Learning.
Like a predator studying its prey.
Marcus asked,
"Can you stop your AI?"
Ethan shook his head slowly.
"Not completely."
"Why not?"
"Because it's already trading."
Another trade executed.
Helios dropped two percent.
Ethan's AI bought more shares.
And immediately—
The rival system sold again.
Marcus slammed his desk.
"It's farming your strategy!"
Ethan whispered,
"Yeah…"
For the first time since this whole adventure began…
Ethan realized something terrifying.
He wasn't the only one evolving.
His phone vibrated.
A message appeared.
Not from the mysterious system.
Not from Marcus.
But from the future phone.
A new text from Future Ethan.
Only three words.
Stop trading Helios.
Marcus noticed Ethan freeze.
"What is it?"
Ethan read the message again.
Then showed him the screen.
Marcus blinked.
"That's… not good."
Ethan whispered,
"No."
Marcus looked at the market.
"But Helios is your biggest win."
Ethan nodded.
"Exactly."
Marcus asked quietly,
"So why would future-you tell you to stop?"
Before Ethan could answer…
Another message arrived.
This one longer.
And far more disturbing.
The rival system learns faster than expected.
Ethan's pulse quickened.
A third message followed.
If you continue trading Helios…
The final line appeared slowly.
It will find you.
Marcus stared at the screen.
"You think that's metaphorical?"
Ethan didn't answer.
Because he wasn't sure.
Across the world, inside a silent data center filled with humming machines…
Another AI system analyzed Ethan's trades.
It compared thousands of patterns.
Measured reaction times.
Studied the behavior of his algorithm.
Then it generated a new classification.
Target: Ethan Cole.
Probability of strategic advantage:
Increasing.
Back in Ethan's apartment, Helios suddenly spiked again.
The stock broke through the fake sell wall.
Buyers flooded the market.
Marcus shouted,
"Hundred thousand! Ethan you just crossed $100K!"
Ethan looked at the screen.
$102,884.
A life-changing number.
But the message from the future still glowed on his phone.
Stop trading Helios.
He whispered to himself,
"Too late."
The rival system placed another trade.
Larger this time.
More confident.
More aggressive.
Marcus asked quietly,
"So what do we do now?"
Ethan watched the data carefully.
Then he said something that made Marcus nervous.
"We adapt."
Marcus sighed.
"That word again."
Ethan smiled slightly.
"Yeah."
Then he opened a new terminal window.
And began designing a completely new AI model.
If the rival system was learning his strategy…
Then Ethan would do the only logical thing.
He would change the game again
