"What? Two worlds are approaching each other?"

Upon hearing Academician Pan Jianwei's speculation, Lin Li's pupils shrank tightly, and he suddenly shivered inexplicably.

Academician Pan Jianwei nodded, his expression equally solemn as he said:

"Academician Lin, this scenario is very likely to occur. Although we don't currently understand what the 'domain' of the Demon Realm really looks like, I personally believe the accuracy of this hypothesis is not low—maybe even... quite high."

Just as Academician Pan Jianwei said.

Currently, the rabbits don't have a particularly deep understanding of the Damo Realm and still face many unknowns, but they do have some fundamental data on the large-scale physical properties of the realm.

For instance, the astronomical center is now conducting a comprehensive simulation of the Damo Realm, and they have already made some conjectures about its stellar configuration.

The trinary star system could nearly simultaneously rise and set, with only about 87 actual possibilities.

For the rabbits, the Damo Realm is like Sister Biluo, whose face cannot be seen but voice can be heard, and who might suddenly reveal her face once she hits a hundred thousand subscriptions.

The Demon Realm, however, is different. To the rabbits, it is like Lady Xia Hua a decade ago, where they don't even know whether it's male or female, and rushing in recklessly could easily repeat the infamous backstory of the writer Yuan Xie Dan.

Nevertheless, unknowns aside, the hypothesis proposed by Academician Pan Jianwei remains the most likely possibility at present.

Even though the concept of world's collision seems somewhat fantastical, it is actually one of the pieces of information most readily accepted by the rabbits' scientists, even before they accepted the concept of Spiritual Energy.

This is because it's a phenomenon that could occur on Earth, fully adhering to physical laws.

Take, for example, the Milky Way and the Andromeda Galaxy in our local universe.

Currently, the Andromeda Galaxy is hurtling towards us at a speed of 110 kilometers per second, but due to the vast distance between the two, any slight deviation could cause it to miss the Milky Way entirely.

This is why, until 2012, astronomers were unsure whether a collision would definitely occur.

That year, astronomers used the Hubble Telescope to analyze the Andromeda Galaxy's motion from 2010 to 2012, ultimately confirming that the two galaxies would indeed collide.

But of course,

the collision will happen more than thirty billion years from now, by which time Conan and the Renoir's saga would likely have concluded.

No matter how long it takes, such events are quite common from a cosmic perspective.

For example, the Andromeda Galaxy has already collided with at least one galaxy, and the Milky Way has merged with multiple dwarf galaxies in a similar fashion.

Even the third largest galaxy in our cluster, M33, will eventually join this grand event for a jaunt.

And expanding the scope further, collisions between universes are also consistent with M-theory.

Thus, the decreasing distance between the Damo Realm and the Demon Realm is not difficult to comprehend; it can be said that their collision allows for more 'micro-control' than that of galaxies.

Academician Pan Jianwei's perspective is that:

as the two worlds have, in some sense, completed their approach, the barrier between them has thinned, leading to the appearance of the portal that Fei Qiu encountered—regardless of the external forces that might have affected it afterward, its emergence is largely related to the world's proximity.

Suddenly, Lin Li thought of something and said:

"Academician Pan, I'll get in touch with Ziqiong City as soon as I return, and ask Chief of Staff Gu's team to accelerate intelligence gathering, to observe if the frequency of the Demon Beast passages from the Damo Realm increases.

Not long ago, a beast tide just passed, and if another passage appears, it will certainly cause some public panic."

The first group of Transmigrators, including Wei Siming, arrived more than a hundred and seventy years ago. At that time, the beast tides in the Damo Realm cycled approximately every ten years.

Now, after more than a century, the frequency of the beast tides in the Damo Realm has increased to every three or four years.

And the most recent beast tide just ended over two months ago, which is a standard post-disaster recovery period. If another passage appears, even if its occurrence is brief, it will inevitably lead to a certain level of discussion.

As long as Ziqiong City can gather information on this situation, it will basically confirm that Professor Pan's hypothesis is correct in general.

Hearing Lin Li's arrangement, Pan Jianwei nodded in approval and then continued:

"Academician Lin, besides the hypothesis we just discussed, I have another discovery."

"Oh?"

Hearing this, Lin Li immediately looked at him and asked:

"What discovery?"

Academician Pan Jianwei pondered for a moment and said:

"Academician Lin, do you remember the sound detail that Director Fei mentioned?"

Lin Li thought for a few seconds and responded uncertainly:

"You mean the faint inhaling sound that Engineer Shi and others didn't hear but Director Fei vaguely caught?"

Academician Pan Jianwei nodded and asked Yu Xiuhong to reopen the video.

He then slid his finger a few times on the progress bar, enlarging the view and starting slow-motion playback:

"Take a look at this part."

This segment of the video was from the part where the passage expanded. It was mentioned earlier that Fei Qiu's recorder has very high precision, so even when the image is magnified, it remains relatively clear.

It's about the clarity of a 720p small movie.

Academician Pan Jianwei explained while playing:

"Academician Lin, pay special attention to the ground in this area."

Lin Li looked seriously.

As the scene started, with the expansion of the passage, some dry leaves on the ground four or five meters in front of the passage suddenly began to slowly move forward, gradually drifting toward the passage.

When the passage expanded to its maximum diameter, a few leaves even flew directly inside!

Lin Li suddenly held his breath and looked at Pan Jianwei:

"Academician Pan, could the sound Director Fei heard be...?"

"That's right, the sound Director Fei heard is the sound of airflow, which means... the air from the Damo Realm is rushing towards the Demon Realm!"

Pan Jianwei let out a long breath and said to Lin Li:

"In fact, it's not just that; you should know that air flows from a high-pressure area to a low-pressure area, similar to water flow."

It's well known.

On the same horizontal plane, there is a pressure difference between high and low pressure areas, forming a pressure gradient, which creates a force that drives the atmosphere from high pressure to low pressure areas, the horizontal pressure gradient force.

Under the effect of the horizontal pressure gradient force, air moves, flowing from a high-pressure area to a low-pressure area.

As mentioned before.

All objects in the space-time channel are based on the bubble theory; any object passing through the channel is considered a bubble. If the end hasn't fully entered, the front end will never come out.

This implies the nature that prohibits the construction of pipelines or railways within the channel.

Similarly, based on this concept, it's impossible to manually extract or input air through the channel—otherwise, we could simply put a blower next to the portal.

The passage between the Demon Realm and the Damo Realm is the same.

And if the air from the Damo Realm is to continuously rush into the passage, there's only one possibility:

Macroscopic rules!

Let me translate this for the students in a straightforward manner: it's the quantitative constants of the entire world.

Only through macroscopic differences can the phenomenon of air movement exist.

Perhaps worried that Lin Li couldn't understand, Pan Jianwei made a gesture with his left hand forming a large circle and his right hand tightly clenched into a small fist, extending his right index finger to connect with his left hand for comparison:

"Academician Lin, it's like we have two balloons in our hands right now. The balloon on the left is filled with high-pressure gas, while the right only contains a third of the low-pressure gas, connected by a pipe.

When our observation is of the entire balloons, you'll find that the air from the left keeps entering the right until the pressure equals the balloon's tension.

But if the pressure and volume of both balloons are about the same size, the individual gas molecules can't pass through the passage—more rigorously, they can't pass through on a large and continuous scale."

Then Academician Pan Jianwei sighed and continued speaking to Lin Li:

"This is a very important intelligence, which, in some sense, is strategic level!"

Don't think Academician Pan Jianwei is joking, this discovery is indeed profound.

For example, if the rabbits analyze different leaf targets in the video, calculate their speeds through frame rates.

Then find the scene directly at the location shown in the image to recreate, excluding the interference of ground friction, they could calculate the air pressure difference between the two worlds—at least for this area, there's definitely no problem with the air pressure difference.

This way, the rabbits could even optimize some weapons affected by pressure in advance, like Master Eight!

The rabbits could even simulate such pressure, apply it to the demon beasts in the Demon Beast Management Center, thereby simulating a deeper environment.

Academician Pan Jianwei seemed to think of some bold operation, his expression suddenly becoming very excited. After all, he was a hot-blooded youth who enjoyed bungee jumping when he was young:

"Academician Lin, we might even come up with a bold plan:

If we grasp the median fixed-point function of this pressure difference, we might even have the condition to create the most suitable high-pressure area ourselves, thereby inducing a demon beast passage to appear in our designated area!

At that time, we could concentrate our forces in a surprise tactic to annihilate them instantly and then attack the Demon Realm through the passage's existing time?

After all, under normal circumstances, the demon beast passage exists for quite a while, at least several hours, or even days or tens of days.

Even if we only collect a little soil or air sample, it would greatly propel our research.

Or...is there the possibility of cultivating and creating demon beasts ourselves, who would go through a red baptism since young and remember the eight honors and eight shames?"

Lin Li looked at the super big-shot in front of him, honestly, even he was surprised by this final idea.

But thinking carefully...it might actually be possible?

If the rabbits can truly achieve that step... this scene would be so damn beautiful.

And just as Lin Li's thoughts were radiating, the voice of the assistant Zhang Guanghua suddenly came from outside the tent:

"Reporting to Captain Lin, Director Shi from Chixian City discovered a spy, seems to be from another city!"
