The number on Ethan's screen still looked unreal.
$102,884
Only a month ago he had counted coins to buy instant noodles.
Now he had crossed one hundred thousand dollars.
Marcus was still celebrating.
"Six figures, man! Do you understand what that means?!"
Ethan nodded slowly.
"It means the game just got harder."
Marcus sighed.
"You really don't know how to enjoy things, do you?"
But Ethan wasn't listening.
Because the warning from the future phone still echoed in his mind.
Stop trading Helios.
And worse:
It will find you.
Ethan stared at the order book again.
The rival system was still there.
Quiet.
Patient.
Watching.
It had stopped placing large trades.
Instead, it used tiny probes.
Single-share orders.
Microsecond reactions.
Testing.
Learning.
Marcus leaned closer to the microphone.
"So what's the plan, genius?"
Ethan cracked his knuckles.
"We build something new."
Marcus groaned.
"Oh no."
Ethan opened a new terminal window.
Lines of code filled the screen.
His old AI system was designed to do one thing:
Predict the market.
But prediction no longer worked.
The timeline had changed.
Historical patterns were collapsing.
And rival systems were learning from his behavior.
So Ethan needed something different.
Not prediction.
Adaptation.
Marcus watched the code scrolling.
"What exactly are you building?"
Ethan answered without looking up.
"An evolutionary model."
Marcus blinked.
"That sounds expensive."
Ethan began explaining.
"Traditional trading algorithms try to forecast the next price movement."
"Yeah."
"But evolutionary systems do something else."
Marcus waited.
"They create thousands of strategies," Ethan said.
"Then?"
"Then they let them compete."
Marcus frowned.
"Compete?"
Ethan nodded.
"Each strategy trades in a simulation."
"The ones that lose money die."
"And the profitable ones reproduce."
Marcus stared at the screen.
"That sounds… kind of brutal."
Ethan smiled.
"Nature is brutal."
Lines of code continued flowing.
Inside the program, Ethan built a digital ecosystem.
Thousands of tiny trading strategies.
Each slightly different.
Different risk levels.
Different reaction speeds.
Different ways of interpreting market signals.
Marcus watched in fascination.
"You're basically creating a jungle."
Ethan nodded.
"Exactly."
"And only the strongest strategies survive."
The system began compiling.
Ethan pressed Enter.
The evolutionary engine activated.
Instantly, thousands of virtual traders appeared inside the simulation.
They began buying.
Selling.
Failing.
Dying.
Replacing each other.
Learning.
Marcus whispered,
"That's insane."
Ethan leaned back.
"Give it a minute."
The first generation finished quickly.
Most strategies failed instantly.
Losses.
Bad timing.
Overexposure.
The system eliminated them.
New strategies evolved.
Marcus stared at the screen.
"Generation two already?"
"Yep."
The numbers started improving.
Generation 5.
Generation 10.
Generation 23.
The surviving algorithms were getting smarter.
Not by prediction.
But by adaptation.
Marcus pointed at the results.
"Wait… those profit curves…"
Ethan nodded.
"They're learning."
But then something strange happened.
The system detected an anomaly.
A strategy appeared that didn't follow any known model.
It didn't predict trends.
It didn't follow momentum.
It didn't react to volatility.
Instead…
It watched other algorithms.
Marcus leaned closer.
"What's that one doing?"
Ethan frowned.
"I'm not sure."
The strategy waited patiently.
Then, when another algorithm made a move…
It reacted instantly.
Almost like it knew what the other system would do next.
Marcus whispered,
"That's creepy."
Ethan nodded slowly.
"Yeah."
The system ran another generation.
The strange strategy survived.
And then…
It improved.
Generation 31.
Generation 32.
Generation 33.
Its profits exploded.
Marcus stared at the screen.
"Ethan… that thing just outperformed every other strategy."
Ethan's eyes narrowed.
"That shouldn't be possible."
He opened the code structure.
The algorithm had evolved its own logic.
Something Ethan had never programmed.
Marcus asked carefully,
"Is that… normal?"
Ethan shook his head.
"No."
Marcus leaned back.
"That sounds bad."
Ethan whispered,
"It might be amazing."
Because the strategy had discovered something unique.
Instead of predicting the market…
It predicted other algorithms.
Marcus blinked.
"Wait… you mean it can predict the rival system?"
Ethan smiled slightly.
"Exactly."
At that moment, the Helios chart moved again.
The rival system placed another probe trade.
Small.
Precise.
Testing Ethan's activity.
Ethan activated the new algorithm.
"Let's see what you can do."
The AI responded instantly.
Instead of copying Ethan's old strategy…
It waited.
Studied the rival trade.
Then it placed a counter-order.
Perfectly timed.
Marcus gasped.
"Did you just see that?"
Ethan nodded.
"Yeah."
The rival system reacted.
Another probe.
Another test.
But Ethan's new algorithm responded faster.
Smarter.
Marcus whispered,
"That thing just beat the rival system."
For the first time all day…
The mysterious terminal printed a message again.
Unexpected development detected.
Ethan typed immediately.
What happened?
The response appeared slowly.
You created a strategy outside predicted models.
Marcus grinned.
"So basically you broke the simulation again."
Ethan watched the numbers rising.
$104,000.
$105,000.
The new AI was working.
Better than anything he had ever built.
But the system printed one more message.
Short.
And strangely cautious.
Warning.
Ethan leaned closer.
The next line appeared.
Algorithms that evolve independently become unpredictable.
Marcus frowned.
"That sounds like a movie line."
Ethan didn't laugh.
Because the final line appeared.
You may have created something you cannot control.
Marcus looked at Ethan.
"Please tell me that's dramatic exaggeration."
Ethan stared at the new algorithm running on his screen.
Watching.
Learning.
Adapting.
Growing stronger every second.
Then he said quietly:
"I hope so."
