Did You Destroy the World Today?
Chapter 58: Higher-Dimensional Space

A mirror?

Flat?

What does that mean?

Lin Xu frowned deeply as he read Bai Mo's message.

Before he could reply, another message from her had already arrived.

Bai Mo:

"What else do you know? Why are you so familiar with these things?"

"Is the extra-dimensional experience you mentioned the same as what I call mirror space? Have you personally experienced it?"

"What is the apocalypse? Does it truly exist?"

Looking at Bai Mo's messages, Lin Xu momentarily didn't know how to respond.

Did the apocalypse exist?

Of course it existed, and according to current clues, it would arrive in 20 years.

But higher-dimensional space?

That didn't seem similar to the "mirror space" Bai Mo described.

Based on Skull Head's wife's description, it was more like a "singularity space" dimension.

What Bai Mo described... seemed more like some kind of two-dimensional space?

After brief consideration, Lin Xu typed his reply:

"You can assume I've entered that space, but my experience was different from yours."

"Describe in detail what you mean by mirror space."

Moments later, Bai Mo's response came.

Bai Mo:

"Different is exactly right!"

"It's a... higher dimension!"

"Everyone's experience is different!"

Lin Xu:

"Why?"

After sending the message, Bai Mo called moments later.

She didn't give Lin Xu time to speak, immediately firing off words like rapid gunfire after the call connected:

"It's a higher-dimensional space!"

"Like when a two-dimensional being is pulled into three dimensions - you'd never know where you'd land on the Z-axis!"

"I see a plane because I'm further along the Z-axis, maybe even at its endpoint."

"You might see layered cross-sections because you're still on the Z-axis!"

"What everyone sees is different - that doesn't matter at all!"

"What matters is that you saw it! Anyone who's entered that space would immediately sense its difference!"

"...I understand."

Lin Xu exhaled deeply before asking:

"What exactly did you see?"

"A plane! A mirror!"

"Like countless mirrors stacked together, their reflections endlessly nested in infinite recursion!"

"But those reflections... I can't describe them."

"From my perception, I thought they were flat, but actually they weren't - it was a comparative flatness... How should I explain..."

Bai Mo's words became somewhat disordered, but Lin Xu suddenly understood her meaning.

"When a two-dimensional being ascends to three dimensions, with only two-dimensional vision, its original two-dimensional world would appear as just a one-dimensional line formed by the intersection of visual plane and dimensional plane."

"When three-dimensional beings ascend to higher dimensions, all we can see is a two-dimensional plane formed by the base circle of our vision cone intersecting the three-dimensional world."

"Lower-dimensional beings ascending higher inevitably perceive their native dimension as reduced - sensorily reduced."

"That's why you thought what you saw was flat."

"It's unrelated to the Z-axis, but rather to your 'orientation' in the higher-dimensional space."

After he finished speaking, Bai Mo on the other end fell silent.

Then her slightly trembling voice came through:

"Yes!"

"That's exactly it!"

"How do you know?? How can you describe it??"

"...I don't know."

Lin Xu slowly shook his head.

He himself didn't know how he'd spoken those words.

It was like some subconscious knowledge - upon hearing Bai Mo's description, the words had instantly come out.

Just like when he'd blurted out "Mars."

After a pause, Lin Xu continued:

"Probably because I've been there, so I understand."

In truth, he'd never been.

He'd only heard Skull Head's wife describe it.

But in this moment, Bai Mo completely believed him.

"What... what should we do??"

"Never mind what we should do for now..."

Lin Xu sighed.

"You haven't answered my question."

"Why do you want to go to Mars? Why space?"

"This is important!"

"Because I saw Mars in that space!"

Bai Mo answered without hesitation:

"It was different from other planar objects... it was three-dimensional!"

"By your explanation, it likely shared a higher dimension with me at some instant."

"Also, I saw a spacecraft..."

"I don't know what kind, but it was flying toward Mars!"

"It was also three-dimensional... I want to know where it entered that higher-dimensional space from!"

Zhurong rover.

Lin Xu's hair stood on end.

Now he finally understood what made this Mars probe so special.

It had passed through higher-dimensional space.

Perhaps just a higher-dimensional "bubble," but having entered, it must have been altered.

That's why it became so crucial.

So crucial that everyone seeking apocalypse clues needed to physically possess it!

One mystery had been solved.

Of course, deeper mysteries followed.

Where did that higher-dimensional space come from?

How was it connected to the apocalypse??

Such questions likely couldn't be answered simply from the world within the wristband.

Because its inhabitants probably hadn't solved this either!

He'd reached the boundary.

Beyond lay only the vast, uninhabited starry void.

To solve this, only one method remained:

A temporal pincer movement.

Acquire technology from the future, utilize current resources, and initiate the process twenty years early!

Lin Xu looked at the wristband.

He realized its appearance in his possession was no accident.

He exhaled softly.

Then he said to Bai Mo:

"What you saw was the Zhurong Mars rover."

"I guessed that!"

Bai Mo immediately responded.

"Then why did you say you hadn't heard those keywords?"

Lin Xu frowned.

"I was too nervous... That's not what I meant, I meant I didn't..."

"Enough."

Lin Xu interrupted.

"Regardless, we're allies now."

"Our information exchange must be completely transparent - you must tell me everything you know."

"Take time to organize your clues and send them to me."

"Understood."

Bai Mo answered immediately.

"What about Tianqiong Technology? Should I still go?"

"Yes."

Lin Xu answered gravely:

"You'll go, and you'll push for Star Voyager-1's accelerated launch."

"Because... you'll be its astronaut!"
