…
No one could have predicted that, on such an ordinary morning,the "Black Box" that had suddenly appeared not long ago—covering the entire desert and drawing worldwide attention—would vanish in this way.
No explosions.No bombardment.Humanity had done nothing to interfere.
And yet, this morning…
That "Great Wall" spanning over 300,000 square kilometers simply vanished without a sound!
Just as mysteriously as it had appeared.
Even more shocking for all research teams and the countless witnesses from cities near the northwest region was what replaced it:the barren desert, once filled with endless yellow sand, had transformed into a vast oasis.
So immense.So impossible to ignore.
Even from dozens of kilometers away, the outlines of mountain ranges could be seen clearly.
Any attempt to "cover up" such a sight was meaningless.
And as the news spread upward to government authorities, outward to the public, and across the world, it drew everyone's attention.
"The Tack Black Box has disappeared!!"
In cities across both hemispheres—whether in daylight or under the night sky—countless connected devices buzzed to life.
Through group chats, news feeds, push notifications… this explosive story instantly filled people's screens,spreading like a virus across the global internet.
On countless platforms, the topic's discussion and views skyrocketed at a terrifying pace.
News outlets, big and small, rushed to publish stories and videos, feeding the frenzy like rolling snowballs.
Half an hour later, "Black Box Disappears" topped every domestic and international trending list.
One hour later, it was the #1 global headline.
Once again, the world's gaze turned toward the distant East.
"Bzzz—"
At the Lishan Martial Hall, inside the study.
Lin Tack stood quietly by the Sand Table.In his sight, with the disappearance of the isolation barrier, faint ripples appeared where the oasis met the outside world.
That was the Evolution Sand Table adjusting the two ecological systems, reconciling subtle differences.
Sections of land near water shifted—some areas rose, others sank.Underground rivers were rerouted by mysterious forces to merge with the external environment.
Some surface rivers even "grafted" directly into outside riverbeds, water levels automatically equalized.
This was all part of the "adjustment."Even though Lin Tack had already witnessed such powers before, when the Sand Table had moved desert highways and facilities…
Seeing it again still filled him with awe.
Once the adjustments were complete and the Sand Table entered "Observation Mode," the phone on his desk buzzed violently.
He picked it up, raised an eyebrow, and wasn't surprised.
The notifications list was overflowing—either news alerts or messages from group chats.
Opening the company chat, the first thing he saw was several forwarded headlines.The thumbnails confirmed it: news of the Tack Black Box's disappearance.
"Big news! Big news! The Great Wall is gone!!"
One lively coworker shouted in the chat.
Replies scrolled in rapidly:
"I just saw it too, was about to post here."
"Damn, it's already trending #1. Another huge scoop!"
"You guys just treat this as entertainment? Am I the only one worried? It appeared out of nowhere, now disappears out of nowhere… feels like some unseen hand is controlling everything."
A girl added a nervous emoji.
"What's the point of worrying? Doesn't seem bad so far… let's wait for the official statement."
The group seemed surprisingly "calm."
Lin Tack skimmed the chat, then habitually opened Weibo.
As expected, #TackBlackBoxDisappears was locked at the top of the trending list.Second place: #Oasis.
Clicking in, he scrolled quickly:
Breaking: #TackBlackBoxDisappears# — Officially ConfirmedAt 7:10 this morning, the "Great Wall" silently vanished.The desert within transformed into a primeval oasis.Nearby research teams confirmed immediately, and the area has been sealed off…
He scrolled further.Official news agencies, major media outlets, influencers—all reposting, all commenting.
Underneath, netizens flooded comment sections:
"I'm shocked! Just got to work and saw this. Whole office is buzzing. We didn't even have our morning meeting—something huge is happening!"
"I'm scared. So the Black Box wasn't just random, right? First sealed off, now lifted, desert turns green… no way that's a coincidence."
"Is this real life? Feels like I'm reading a sci-fi webnovel… what if aliens really are watching Earth? What do they want?"
"What do they want? Maybe to help with desertification? If so, someone give the aliens a medal…"
Lin Tack read through the posts, half amused.
But beneath the jokes, he could feel the unease and tension bleeding through.
No one knew whose hand was behind all this.No one knew if some "will" truly existed—and what it intended.
He scrolled again and came across a long-form post:
"Just heard the news about the Black Box disappearing. Checked with some friends—confirmed real.The oasis is no mirage, it's physically there.Research teams are already using drones and satellites to observe further. The area is under lockdown.This isn't just a local or national issue—it concerns 7 billion people.Every move made by the frontline teams is tied to the hearts of humanity…"
"So everything must be done with caution.As ordinary people, all we can do is wait patiently, avoid spreading rumors, and trust official channels.I know many are worried, even fearing this is the work of an unknown advanced civilization.But from what we've seen—there's been no malice.When the Black Box first appeared, highways, buildings, people were all safely moved out. That even showed a trace of goodwill."
"That doesn't mean we drop our guard.Vigilance is crucial.But panic helps no one.Change always brings both risk and opportunity.This could be danger—or it could be the greatest chance humanity has ever had.And the fact it appeared in our country… may be our once-in-a-lifetime opportunity."
"Of course, maybe I'm overthinking.Maybe eventually, it will be proven that we were worrying for nothing.Maybe the so-called Black Box was just some natural phenomenon we can't yet explain."
The post was long.
Lin Tack checked the author: a famous internet industry influencer.No wonder it had gone viral.
Thousands of comments below—mostly agreement, though some disagreed:
"Agree! Vigilance yes, but blind panic no."
"Too idealistic. Advanced civilizations don't necessarily mean higher morals. Look at humanity—we fight more than most species in nature…"
The debate was fierce.
As the story grew, discussions sparked across industries.Different viewpoints clashed, drawing huge attention, becoming a phenomenon of its own.
And such debates weren't confined to one country—they erupted everywhere.
