The store went quiet for two full seconds.
On the other end of the comm, Zhou Xubai didn't answer right away.
Maybe because even he hadn't expected this.
He had just pushed through an escalation order—
—and within moments, the store had already closed its first deal with whatever was behind the door.
The first safe route had been posted to the shelf.
Right in front of him.
Lin Wu stood behind the counter, still holding the snow-salt crystal.
Inside it, the pale glowing line of the White Tower Outer Ring Safe Route — Night Use Only shone steadily, like a path someone had already stepped out through a blizzard.
At this point, it wasn't just collateral from the other side.
It was bait.
Visible. Valuable.
And impossible for reality-side command to ignore.
"Qin Zheng," Zhou Xubai finally said. His voice was still cold, but no longer pressing down like a direct order. "Confirm what you're seeing on site."
Qin Zheng looked from the shelf to the crystal in Lin Wu's hand.
"Confirmed," he said heavily. "Grey Tower has put up the first safe route as collateral. White Tower Outer Ring. Night route."
The expressions on the second team outside changed immediately.
To anyone else, it might have sounded like intel.
To them, it was survival.
A route meant deployment options. Evacuation options. Mission access.
A route meant people lived.
Zhou went silent for a beat.
Then his voice came back lower.
"Lin Wu."
"Mm?" she answered lazily.
"You were right," he said at last. "If I want this now, I negotiate on your terms."
Pei Wan's eyes lifted first.
Qin Zheng said nothing.
Because that sentence meant one thing, very clearly—
someone from the highest tier of authority had stepped down from taking control to making a deal.
And Lin Wu had dragged him there by force.
"Good," Lin Wu said, setting the crystal carefully beside the register. Her fingertip tapped the ledger once. "Then get in line."
"What do you want?" she asked.
"I want duplication rights for the first route," Zhou said without detouring. "And synchronization rights for every future update Grey Tower provides after this."
The store went still again.
Not because no one understood him.
Because they understood him perfectly.
He wasn't asking to look at the route.
He wasn't asking for one pass through.
He was asking for copy rights and update access—
which meant he wanted a permanent pipeline from Lin Wu's store into the real world.
Professional.
Aggressive.
Efficient.
Lin Wu smiled.
"Mr. Zhou," she said, "that sounds a lot like paying once and taking a cut from the next several deals."
A pause.
"Name your price."
There it was.
That was the phrase she liked.
She didn't answer immediately.
Instead, she looked down at the ledger, then swept her eyes across the people in the store.
Zhou Qiming, with the experimental chains from Subject One and Subject Two.
Qin Zheng and the second team, holding emergency authority and access to real-world resources.
Pei Wan's side—boots-on-the-ground people. The kind who could actually move things, build things, execute.
Cen Dong and Qi Ye—the most valuable repeat customers and guides she had beyond the door.
So what was she short on now?
Not medicine.
Not food.
Not water.
What she lacked now was infrastructure—
the kind that could actually support a business at the mouth of a door.
"You want the route? Fine," Lin Wu said. "But I'm not selling duplication rights."
No objection came immediately.
"Why?" Zhou asked.
"Because the route isn't yours," Lin Wu said smoothly. "Grey Tower posted it as collateral to my store. It's not public property."
"If I let you duplicate it, I'm taking someone else's goods and using them to build your channel."
"That's bad business."
Qi Ye's gaze shifted slightly.
Good.
She wasn't just ruthless.
She knew how to protect inventory.
That was what made her a real shopkeeper.
"Then what are you selling?" Zhou asked.
"Transit authorization," Lin Wu said clearly. "If reality-side personnel, cargo, or teams want to use this first route, they register through me."
"What you pay for isn't the map."
"It's my approval."
Silence.
Qin Zheng understood immediately, and his expression darkened.
Because that was far harsher than selling the route itself.
Selling the route was a one-time transaction.
Selling transit rights meant she was building a toll gate.
A real one.
Zhou was silent for two seconds.
"Specific terms."
Lin Wu wrote four characters into the ledger.
Reality-side route access.
Then she began.
"First: a complete survey map of the West District Collapse Zone."
"Second: a callable inventory list for Hengan Bio's cold storage, pharmaceutical storage, and backup energy reserves."
"Third—"
She paused, then lifted her eyes toward the comm unit still glowing red.
"I want the full evaluation standard for a 'living interface.'"
That was the line that truly froze the room.
Zhou Qiming looked up sharply.
Pei Wan's expression tightened.
Even Qin Zheng visibly frowned.
Because this was no longer just materials for access.
She was openly asking for the framework—
the actual standard used to decide what she was worth, what category she fell into, and how she might one day be handled.
It was sharp.
And dead accurate.
The comm remained silent longer this time.
Zhou Xubai didn't answer immediately.
Because he knew the same thing she did.
The first two were resources.
The third was the ruler.
Once someone got the ruler being used to measure them, half the game changed.
And Lin Wu was exactly the kind of person you did not want getting ahead of your math.
"The third item is impossible," Zhou said finally, his voice turning colder. "That is not trade-level material."
"Then I don't sell."
She answered instantly.
No hesitation.
That, more than anything, stalled him.
Because right now, he was the one who wanted the route.
Not her.
The tension held for three seconds.
Then, for the first time, Zhou adjusted.
"I can give you a redacted version," he said. "Ranking logic. Loss-of-control thresholds. Observation indicators."
"Response permissions and reporting chains removed."
Lin Wu didn't answer at once.
She ran through it quickly in her head.
Good enough.
For her, the most valuable part was never the paperwork of who might come after her.
It was the measuring standard itself.
What made them classify her as cargo, as infrastructure, or as a controllable interface.
If she had most of the ruler, she could live without the rest for now.
"Fine," she said. "Then I add one more condition."
Zhou clearly saw it coming. "Go on."
"For the first safe route, your side gets exactly one registered transit slot."
"Personnel, cargo, timing, and destination all get reported to me in advance."
"Anything after that goes back in line."
Good.
That was the point.
She wasn't turning this into a single sale.
She was turning it into recurring business.
Zhou went quiet for a second.
"You're writing rules for yourself."
"Yes," Lin Wu said. "I run a store."
That even got Qin Zheng to fall silent.
Because it sounded ridiculous.
And yet it made perfect sense.
The world outside was starting to look less like a disaster zone and more like first contact between two systems.
And Lin Wu, somehow, was still thinking in the same terms:
How goods were stocked.How customers were queued.How routes were billed.
And somehow, that was exactly how she kept taking control.
"Done," Zhou said at last.
The system lit up immediately.
[High-value reality-side route transaction completed][Store reputation +5][Unlocked prerequisite: Registered Transit]
Good.
Lin Wu's mood improved on the spot.
This one had real weight.
"How are you delivering the materials?" she asked.
"Qin Zheng has a temporary access key," Zhou said. "The survey map and inventory list can be dropped locally first."
"The redacted living-interface standards will arrive by encrypted delivery in ten minutes."
"Perfect," Lin Wu said. "Then now you can buy the first slot."
That got a pause.
"You're charging again?"
"Obviously," Lin Wu said, as if he'd asked something stupid. "The last deal bought rules. It didn't buy the ticket."
This time Pei Wan actually raised a hand to her forehead.
She had completely surrendered.
Lin Wu wasn't just doing business.
She was training everyone around her into paying customers.
Even Zhou went quiet for two seconds.
Then a low response came through the static, almost sounding amused despite itself.
"Fine."
"Write the invoice."
Good.
Another one behaving properly.
Lin Wu turned to a fresh page in the ledger and wrote:
Reality Registration: Route One, First Ticket
Then she looked up.
"Price for the first ticket: three boxes of broad-spectrum anti-infection injectors, two portable water purification modules, and one emergency generator vehicle dispatch authorization."
The second team outside changed expressions again.
Because that wasn't the price of one passage.
That was infrastructure.
She was using a single route ticket to upgrade the store itself.
And Zhou didn't even try to haggle.
"Accepted."
Too fast.
Fast enough that Lin Wu arched a brow internally.
Which told her exactly what she needed to know.
This route was worth far more to them than what she'd just extracted.
Good.
That meant the next price could go higher.
The system prompt flashed again.
[First reality-side registration ticket sold][New function unlocked: Registration Plaque]
On the far right side of the counter, above the little rotating rack that had once held candy and lighters, a small black sign rose silently into place.
A single pale line of text glowed across it:
Today's Registration: 1 / 1
Perfect.
Limited quantity.
Now it really looked like a business.
The store stayed quiet for two seconds before Qi Ye finally spoke.
"You're only releasing one slot?"
"Of course," Lin Wu said without looking up. "The first route is Grey Tower's trial collateral. Reality-side gets one trial ticket."
"If I sell too many, the route collapses."
"If I sell too few, the price never climbs."
Qi Ye watched her and said nothing else.
But for the first time, he understood something very clearly.
The most dangerous thing in this store was not the rules.
Not the door.
Not the shelves.
It was Lin Wu.
Because as long as she stood behind that register, anything chaotic, dangerous, or unknown that landed in her hands—
would be broken down into deposit, trial shipment, collateral, registration, and the next transaction.
She could take a disaster—
and turn it into order.
That, perhaps, was more dangerous than the door itself.
Then the system flickered again.
[Grey Tower response status updated][Second Route Pending → Available to Open]
Good.
Reality-side had just bought the first slot—
and the second route lit up immediately.
Which meant one thing:
both sides were now recognizing the scale of business she was handling.
The light in Lin Wu's eyes finally sharpened into something impossible to hide.
She looked at the grey ticket still resting on the shelf, then at the snow-salt crystal carrying the first safe route.
Then she smiled.
"Good."
"The first real-world ticket is sold."
Her fingertip landed lightly on the ledger.
Steady. Almost gentle.
"Now it's my turn—"
"to negotiate Route Two with Grey Tower."
