After that distant, heavy impact—
the entire street seemed to lose a layer of sound.
Not silence.
More like everything in the background had been turned down at once.
Rain was still falling, but thinner now.Wind pushed in from the north, carrying something strange.
Not blood.Not wet concrete.
Something colder—
like the inside of a chalk wall that had been cracked open.
Zhou Qiming was the first to move.
He rushed to the glass door and leaned in close, staring north.
The color drained from his face.
"…It's cracked."
The moment he said it, everyone moved.
Pei Wan stepped up beside him.
Qin Zheng lifted his gaze.
Even Su Yu shifted half a step toward the shelves, holding Sui Sui tighter—wanting to look, but not daring to fully.
Lin Wu didn't rush.
She checked the system first.
[Reality-side interface fluctuation rising][Source: Northern White Tower sector][Notice: Not structural movement. Projection fissure expanding toward reality]
Good.
The wall wasn't moving.
But that didn't make it better.
Only different.
Then she walked to the door.
From here, the northern skyline had always been heavy and dark.
Now—
it looked like something had been pried open from the inside.
Between distant high-rises, a long, faint grey-white line had appeared.
Not bright.
Not wide.
But once you saw it—
you couldn't unsee it.
Worse—
it wasn't stable.
It was spreading.
Like ink bleeding through water.
"It's not the wall moving," Zhou Qiming said, his throat tight."It's what's behind it starting to project over."
"What happens next?" Pei Wan asked immediately.
"First the temperature shifts. Then direction starts to break. And after that…"His voice turned dry.
"…black snow."
The last two words had barely left his mouth—
when something fell.
Ten meters out, right at the edge of the protection field—
a small, drifting shape descended.
Not ash.
Not rain.
Snow.
The flakes were thin, edged in black, with a faint pale core—like something burned but not fully consumed.
One of them touched the invisible gold-lined boundary.
—hiss.
A soft sound.
It didn't bounce.
Didn't vanish instantly either.
It curled, like something landing on heated metal—
then dissolved into a trace of black vapor.
Zhou Qiming went completely pale.
"It's here."
No one spoke.
Because everyone had seen it.
This wasn't rumor.
Wasn't theory.
Whatever lay beyond the White Tower perimeter—
was bleeding through.
And in front of Lin Wu—
the system continued updating.
[First detection: Black Snow (reality-side)][Notice: Protection field can delay, not eliminate][Recommendation: Establish outer-ring order on reality side]
Outer-ring order.
Lin Wu caught those words immediately.
Which, translated simply—
meant this store couldn't just defend ten meters in front of its door anymore.
If the northern side kept bleeding in—
she would eventually have to extend her rules outward.
Into reality.
And that—
was a much bigger business.
"Zhou Xubai," she said.
"I'm here," came the immediate reply.
"You just bought the first route," Lin Wu said calmly."Now you're adding to the order."
Qin Zheng glanced at her.
At a moment like this—
she was thinking about upselling.
And yet—
it made perfect sense.
Because the one who needed answers about this spreading phenomenon—
wasn't just her.
It was all of Hengan.
"What do you want?" Zhou asked, no detours this time.
Good.
He was learning.
"First: the three northern blocks—switch from containment protocol to registration protocol. No sealing, no blind clearing."
"Second: heavy snow barriers, mobile generators, emergency lighting units. I want them in the back warehouse before morning."
"Third—"
She paused, watching the place where the black snow had just dissolved.
"I want a construction team."
There was a brief silence on the comm.
Pei Wan turned her head slightly.
"A construction team?" Zhou repeated.
"Yes," Lin Wu said immediately. "You wanted to know what I'm building here."
"Now you do."
"I'm paving the road in front of the door."
That made Qi Ye's eyes shift.
Because she meant it.
Not metaphor.
Not strategy talk.
She was literally starting to extend structure outward.
"You're insane," Qin Zheng muttered under his breath.
"Consistently," Lin Wu ignored him.
She waited.
A few seconds later—
Zhou answered.
"First and second, approved."
"The third—I can give you a temporary engineering unit and material access. No full team."
"Fine," Lin Wu nodded. "Then add structural load maps for the northern buildings."
"Done."
The system flashed.
[Crisis-response add-on completed][Store reputation +3][Prerequisite unlocked: Reality-side outer ring construction]
Good.
Logged.
Then—
the second piece of black snow fell.
This one didn't touch the protection field.
It landed across the street—
on the metal shutter of a dead pharmacy.
—tap.
The moment it touched—
a thin black line began to appear across the dull metal surface.
Like wet ink being drawn.
"What is that?" He Qing's face went pale.
Zhou Qiming stared at it, voice tightening.
"It's starting to write."
That landed harder than "it cracked."
Because everyone remembered what Cen Dong had said.
The White Tower perimeter—
had begun exactly like this.
Line by line.
Writing outward.
And now—
reality was being written on.
Which meant—
whatever rules existed beyond that wall—
were no longer staying there.
"Stop it," Zhou Qiming said immediately. "If it completes a phrase, the local coordinates stabilize further."
"What does that mean?" Qin Zheng asked.
"It means…" Zhou Qiming swallowed."The door won't just recognize this store anymore."
"It'll start recognizing other surfaces nearby."
Recognize surfaces.
Lin Wu understood instantly.
Right now—
this store was the only stable anchor.
But if the black snow kept writing—
walls, shutters, glass—
everything nearby could become secondary anchors.
Which meant—
this street would stop being hers alone.
Unacceptable.
"System," Lin Wu said internally. "Can the protection field extend to the pharmacy?"
[Not as a whole][But: "Threshold marking" available]
Threshold marking.
Another new term.
"What does that mean?"
[Using current anchor authority, the shopkeeper may mark a nearby surface with a boundary line][If successful, temporary interruption of black snow inscription]
Good.
That was enough.
"How?"
The next second—
a faint golden pattern surfaced across her palm again.
The same as before.
[Use your hand as the pen]
[Content determined by the shopkeeper]
Perfect.
This time—
the system wouldn't write it for her.
She would.
Lin Wu didn't move immediately.
She looked at the shutter.
The black line was still forming.
Slow.
But continuing.
Then she glanced back—
glass door. shelves. ledger.
Then down at her own palm.
It felt like the entire store—
was waiting for her to write the first rule outside it.
"I'm stepping out," she said.
Everyone looked at her at once.
"No," Qin Zheng cut in immediately. "If you go out now—"
"I'm not asking," Lin Wu said.
"At least let us go with you," Pei Wan said.
"No need," Lin Wu replied calmly. "I'm just going across. Ten meters still holds."
She turned.
"Qi Ye, watch the door."
"Cen Dong, watch the second route."
Then she slid the monitoring terminal onto the counter toward Pei Wan.
"Watch these three indicators."
"If anything changes—log it first, then call me."
Pei Wan: "…"
Even now—
she was delegating observation like it was routine.
But no one argued.
Because this was Lin Wu.
She finished and walked to the door.
It opened.
Cold air rushed in.
Rain. Wind. That grey, dry scent.
The golden lines of the protection field flickered slightly against her shoulder—
as if recognizing her.
She stepped out.
The second team tensed instantly.
Qin Zheng followed half a step—
then stopped as the boundary held him back.
He could only watch her move into the wet night.
Ten meters.
Eight.
Six.
She stopped in front of the pharmacy.
The black line had grown longer.
Trying to form a second stroke.
Lin Wu raised her hand.
The golden pattern in her palm warmed.
Then—
she drew a line.
Simple.
Horizontal.
Not long.
But clean.
And the moment her finger moved—
a faint golden line remained on the metal shutter.
Clear.
Defined.
Like she had just written the first rule of this street.
The black line hit it—
and stopped.
Then—
—cracked.
It broke apart instantly, like the intention behind it had been cut off.
The entire street seemed to pause.
The system lit up.
[Threshold marking successful][Effect: temporary interruption of black snow inscription][Notice: First "shopkeeper boundary line" established]
Good.
Very good.
That familiar, sharp satisfaction rose in her chest.
This was right.
The other side could write.
So could she.
And apparently—
reality accepted her handwriting too.
She was just about to turn—
when something shifted in the sky.
From the grey-white fracture to the north—
a larger mass of black snow broke loose.
Not flakes.
A cluster.
Like shredded dark fibers twisting as they fell—
straight toward her.
Inside the store—
Zhou Qiming's face changed instantly.
"Lin Wu! Back!"
Lin Wu looked up.
The mass wasn't heading for the shutter.
Not the ground either.
It was coming straight for her.
Instinctively, she raised her hand—
But before she could move—
the golden pattern on her palm flared first.
The black mass stopped—
half an inch above her skin.
Not repelled.
Not blocked.
It hovered—
then shifted.
As if it had just found something better to land on.
And the next second—
the entire cluster turned—
and dropped straight into the golden lines on her palm.
