At this moment, atop the cliff.

Looking up at the falling raindrops, everyone's expression was extremely peculiar.

There was certainly some joy.

After all, after working hard for so long, by sheer coincidence, they discovered that their theoretical judgment was actually correct; the cliff was indeed the 'exit' for the Y particles.

And the discovery of the exit meant confirming the location of the Earth Palace.

This was undoubtedly a significant discovery, tremendously valuable.

Alongside the joy came a strong urge to complain:

How could the Earth Palace end up in the sky?

Anyone reading that book would definitely focus their sight on the ground, right?

Old Zhang really isn't a straightforward person!

Of course.

The joy was ultimately greater, especially after the initial disappointment. Everyone had a delight akin to seeing the dawn in the darkness.

Then Wei Fan took to the skies again, flying around the cliff with his Sword Control, ultimately confirming that the winter rain containing the Y particles only fell on the area surrounding the cliff.

As for the area... about a thousand square meters, I guess.

Amidst the thrill, Lin Ziming suddenly heard a sigh.

He looked in that direction.

He saw Daoist Huang at this moment with a complex expression, gazing at the sky, letting the cold winter rain with Y particles hit his face.

His eyes were red, indistinguishable whether from rain or tears.

He quickly asked:

"Daoist Huang, what's...?"

Daoist Huang exhaled a long breath and said:

"Colonel Lin, do you remember the matter I told you about before?"

"Which matter?"

"About my predecessor coming to Qingcheng Mountain to seek the Earth Palace."

Lin Ziming was initially stunned, then realized:

"Daoist Zhang Zhishun?"

Daoist Huang nodded and said:

"The master explored Qingcheng Mountain for a long time and, before leaving, sat at the edge of the cliff, gazing at the sky, and finally sighed and left.

At the time, everyone, including myself, thought that the master gained nothing, but now it seems..."

Upon hearing this, Lin Ziming was startled:

"Do you mean... Daoist Zhang Zhishun discovered the Earth Palace back then?"

Daoist Huang remained silent for a while:

"Perhaps, or it could just be an imagination of mine as his later generation."

The ancestors have passed; further speculation is baseless.

Lin Ziming couldn't help but look up at the sky, saying somewhat regretfully:

"It's a pity Daoist Zhang has already passed away; otherwise, in this grand world now, he might have gone further than us."

He then comforted Daoist Huang a bit before nodding to bid farewell and found Li Bai'an:

"Academician Li, now that we've confirmed the location of the Y particles, what should we do next?"

Li Bai'an thought for a moment and said:

"Colonel Lin, the location of the Earth Palace is clearly above us, but we still need to investigate further to determine its distance, how far it is from us, and whether we can enter it.

So the next step is to pinpoint the location of the Earth Palace and explore why the winter rain with Y particles only falls near the cliff.

Yet at this point, calling it the Earth Palace seems unfitting; let's just call it the Celestial Palace."

Lin Ziming nodded in agreement with this statement, then asked curiously:

"Academician Li, where do you think the Celestial Palace might be situated?"

Li Bai'an glanced at the sky and said:

"Either in near space or in alternate space, only these two possibilities."

Students who studied geography should know.

The atmosphere is close to the ground, ranging from the surface to the stratosphere, the troposphere, and various other regions.

Currently, most countries on Earth have reached a pretty thorough understanding of almost all layers—although this sentence should be followed by several words, except for the near space.

The concept of near space was mentioned once in the Damo Realm when the rabbits first attempted to launch a near space probe.

Its alias is also called the unknown layer, with a height of 40 km to 100 km, both too high and too low.

Saying it's too high is because the air there is extremely thin, planes cannot fly.

Even meteorologists' weather balloons cannot cross the 40 km altitude threshold.

Saying it's too low, on the other hand, is because the air is too dense for satellites, causing satellites to fall into the lower atmosphere unavoidably within weeks due to friction's grip, wasting valuable materials worth billions.

By the way.

Elder Qian's trajectory lies within this layer.

Some amateur scientists even firmly believe that atmospheric creatures exist in this region, similar to the lightning men in Ultraman Tiga.

If full knowledge of this area is 100 points, the current level of understanding from current technology is probably around 7 points—don't assume it's a joke, this score is not exaggerated at all.

Currently, the only universal value we can apply to the unknown layer is 10e-4pa, and to get this number, it took over two billion.

As for alternate space, there's even less need to elaborate; it can also be called an exotic realm, known as a dungeon in games.

Alternate space, unknown layer.

These are the only possible places for the Celestial Palace to exist.

And to confirm its location is actually easy:

Just trace the Y particle-laden rain upwards.

The size of Y particles can be captured by sensor nets, and additionally, Wei Fan can act as a humanoid mobile detector, so operating it has no difficulty.

Of course.

Time is certainly not now.

Firstly, Li Bai'an and others only brought specialized detection equipment; flying a helicopter to five or six kilometers is fine, but going higher definitely requires launching a probe, for which they don't have technological reserves.

Secondly, Wang Qiang estimated the total amount of disappeared nitrogen.

Based on her research results on the Earth's vein flame in the Damo Realm, she calculated the total volume of Y particles produced.

Ultimately realizing that this rain might not last long, hastily ascending might end up with the rain stopping halfway.

Hence, today's detection temporarily drew to a close, and Lin Ziming reported the situation once again to the core team, seeking foreign aid.

Moments later, the core team replied:

A new batch of personnel will immediately depart from the Xichang Satellite Base, arriving on-site within twenty hours.

No choice.

The nation's support is simply so efficient.

After ending the communication, Lin Ziming found Daoist Huang and began transitioning issues related to the new batch of personnel.

Though not bringing excavators tomorrow, since launching probes is involved, the arrangement won't be insignificant.

Taking this opportunity, Li Bai'an, together with Wang Qiang, continued researching the cliff's structure.

Even though the sky location has been confirmed, many mysteries near the cliff still await unraveling.

For instance, why does the winter rain only fall within this area?

Is it an accidental result of the location, or is there something special?

Furthermore, although the Celestial Palace has been confirmed, is there truly nothing else beneath the mountain?

.......

The following noon, the new group of foreign aid arrived.

Compared to Li Bai'an's group of seven or eight, the second batch of foreign aid had many more, numbering over twenty.

The Xichang Satellite Launch Center conveniently lies in Sichuan Province, the birthplace of Huaxia's first geostationary satellite, the first communication broadcast satellite, Chang 3, Tianlian, all from here.

In some sense, during certain periods their confidentiality levels wouldn't be lower than that of the Damo Realm.

As the executor is rather a probe than an airship or even a rocket, despite the launching scaffold being sizeable, it was still successfully erected in less than half a day.

Another night passed.

At 5 a.m. the next day, the rabbits released prepared large amounts of unmarked nitrogen into the area, hoping this might increase Y particle generation.

Despite some nitrogen dispersed out of the cliff area due to wind disturbance, approximately 40% of the nitrogen stayed here.

Meanwhile, five probes ascended early.

Their targets were five different altitudes:

Three thousand meters, ten thousand meters, thirty thousand meters, fifty thousand meters, and one hundred thousand meters.

As planned.

The probes would prioritize their tasks with sensor nets; if this attempt failed, Wei Fan would ascend.

Hmm? This sentence sounds a bit odd?

......

Here's a little bonus game

If you think the Celestial Palace is in alternate space, type 1; if in near space, type 2
