Kiro liked simple things.
Buy low.
Sell high.
Don't ask questions.
And most importantly—
If something moves on its own,
Increase the price.
"…This is a good product."
He held up a small pulsing unit.
thmp…
It responded.
Slightly.
Alive-adjacent.
Problematic.
Profitable.
"…Very good product."
The customer did not look convinced.
"…It moved."
"…Yes."
"…It reacted."
"…Correct."
"…It looked at me."
"…Premium feature."
The customer hesitated.
Kiro leaned in slightly.
Lowered his voice.
"…It adapts."
That was the keyword.
Customers loved that word.
Even if they didn't understand it.
Especially if they didn't understand it.
"…Adapts how."
Kiro smiled.
That practiced, reliable, slightly dangerous smile.
"…To you."
Silence.
The item pulsed again.
thmp…
The customer flinched.
"…I don't think I want something that adapts."
"…That's understandable."
Kiro nodded.
Then immediately placed a second item down.
This one—
Didn't move.
Didn't pulse.
Didn't react.
"…This one does nothing."
"…That's better."
"…It's also cheaper."
"…I like that."
Kiro paused.
Then—
"…It also doesn't defend you."
The customer froze.
"…The other one defends me?"
"…Aggressively."
"…Against what?"
"…Unclear."
"…Unclear?"
"…Situational threats."
The item pulsed again.
THMP—
The customer immediately grabbed it.
"…I'll take this one."
Kiro nodded.
"…Excellent choice."
"…No refunds."
"…Wait—"
Too late.
Transaction complete.
Kiro stepped back.
Counting coins.
"…Good morning."
He didn't like patterns.
Patterns meant predictability.
Predictability meant saturation.
Saturation meant reduced margins.
And right now—
There was a pattern.
More customers.
Same question.
Same concern.
Same reaction.
"…Does it always do that?"
"…Yes."
"…Is that safe?"
"…Relatively."
"…Will it attack me?"
"…Only if necessary."
"…What determines necessary?"
"…User interaction."
"…That's vague."
"…That's flexible."
Another sale.
Another satisfied customer.
Or at least—
A customer who left quickly.
Kiro adjusted his inventory.
Carefully.
He separated the items into categories:
Reactive
Adaptive
Unpredictable (Premium)
"…Good classification."
One of the "Unpredictable" items shifted slightly.
shff…
"…Don't do that."
It stopped.
thmp…
"…Better."
The system flickered.
Merchant System Update
Inventory Behavior: Active
Item Stability: Variable
Customer Satisfaction: Irrelevant
"…Correct."
Customer satisfaction was optional.
Profit was not.
The problem arrived in bulk.
Three adventurers.
All holding the same type of item.
All looking—
Unhappy.
"…We need to talk."
Kiro smiled.
"…Of course."
"…Your products are unstable."
"…They are dynamic."
"…They attacked us."
"…They defended you."
"…From each other."
Pause.
"…That's team synergy."
"…That's not synergy."
"…That's conflict resolution."
"…That's not—"
One of the items pulsed.
THMP—
The others responded.
THMP—THMP—
Kiro stepped back slightly.
"…Ah."
"…That's new."
The items began reacting to each other.
Not violently.
But—
Actively.
Like they recognized something.
"…Why are they doing that?"
Kiro tilted his head.
Watching.
Analyzing.
"…They're syncing."
The adventurers looked confused.
"…That's bad."
"…That's excellent."
"…They almost fought each other."
"…Almost."
"…That's not reassuring."
Kiro crouched slightly.
Observing closely.
The items aligned briefly.
Then stopped.
thmp…
"…Fascinating."
System Notification
New Mechanic Detected: Cross-Item Interaction
"…Oh, that's very good."
"…That's very sellable."
The adventurers stepped back.
"…We don't want these anymore."
"…That's unfortunate."
"…We're returning them."
"…That's impossible."
"…Why?"
"…No refunds."
"…You sold unstable items."
"…I sold evolving products."
"…That's not better."
"…That's more valuable."
The items pulsed again.
This time—
Toward Kiro.
thmp…
He froze.
Just slightly.
"…You're responding to me now."
That was—
New.
Very new.
Very interesting.
The adventurers slowly backed away.
"…We're leaving."
"…That's reasonable."
They left.
Quickly.
Quietly.
Kiro looked down at the items.
Then at his inventory.
Then at the horizon.
Toward the farm.
"…You're changing faster."
The items pulsed again.
thmp…
Not aggressive.
Not unstable.
Just—
Connected.
