That's right.

Although it's somewhat dim inside the Celestial Palace, the scenery is still discernible to the naked eye.

After encoding Omega ccc++ baryons, they can transmit light, a technology that was mastered by the Rabbits as early as 2011.

Currently, many domestic private institutions have the relevant technical reserves, making it a mature particle encoding technology.

However, the breakthrough of the channel carrier was unattainable before, and image transmission was mostly done with waves or rendered photons, rendering this technology unused.

Now, with a microscopic channel made of beryllium ions as the carrier, Omega ccc++ baryons can perfectly transmit images back.

However, although Omega ccc++ baryons can transmit light, they do not — or rather cannot — encode infrared functions.

That is to say, if there is no light inside the Celestial Palace, the screen would definitely display complete darkness.

And the current situation clearly indicates...

There is a light source inside the Celestial Palace!

It must be said, this is a very crucial piece of information.

In a modern context, having enough energy reserve for certain small areas to last a thousand years is not absurd.

Many high-purity energy sources, given the right conditions, can last even until the end of Conan, not to mention two thousand years.

But what era did Zhang Daoling belong to?

The Eastern Han Dynasty!

Back then, there were no nuclear reactors to store energy, and civilian methods of igniting a fire were either candles or bonfires, while outdoors it was bonfires or torches.

At most, when encountering a tyrant in power, one might occasionally light a human lamp or something.

Whether there is oxygen inside the Celestial Palace still needs to be further investigated, but it's certain that low temperatures of tens of degrees below zero are inevitable, ruling out the possibility of combustion emitting light.

Under such circumstances, there's only one possibility for the Celestial Palace to have visible light:

Spiritual Energy!

That is to say.

There must be some device in the Celestial Palace powered by spiritual energy, providing a light source for over two thousand years!

And it's likely that the reserves of spiritual energy in the Celestial Palace are not low at all.

Subsequently, Academician Pan Jianwei reported the situation to the ground.

Soon, Lin Ziming replied:

Next time, make sure to...no wait, increase the effort!

Currently, the limit of the beryllium ion channel installation is eight hundred meters, with the distance from the helicopter to the cyclone being a little over thirty meters.

Let's assume about fifty meters, then the beryllium ion channel can extend about seven hundred and fifty meters inside.

To simplify understanding for some classmates unfamiliar with this concept, let's use another analogy:

Everyone can think of the beryllium ion channel as the frame of a camera lens, while the Omega ccc++ baryons are the lens.

This analogy is honestly not very precise, as the core theories are completely different, but their nature or application is somewhat similar,

so just bear with this comparison.

Anyway, we aren't aiming for perfection, just passable will do.

The principle of a camera is known to everyone: converting optical image signals into electrical signals.

When we capture an object,

the light reflected off the object is collected by the camera lens, focusing on the light-receiving area of the image sensor.

Then, through the imaging device, the light is converted into electrical energy, thus obtaining the "video signal."

The photoelectric signal is very weak and needs to be amplified by a pre-amplification circuit, then processed and adjusted through various circuits.

The final standard signal can be recorded by a recorder or transmitted to a monitor through a broadcasting system.

So, without considering the impact of building obstructions,

the ratio of the beryllium ion channel to the shooting distance is about 1 to 3,

meaning a 750-meter channel can theoretically 'shoot' a scene over two kilometers with a 360° view without any blind spots.

Thus, after receiving Lin Ziming's instructions, Academician Pan Jianwei immediately waved his hand:

"Maximize output power! Hit it hard!"

"Understood!"

A moment later.

The beryllium ion channel suddenly thickened and lengthened as if it had taken medicine!

As if it evolved from a toothpick to a mineral water bottle!

As a result, the transmitted image quality naturally improved significantly.

Very quickly.

The images displayed on the screen became more numerous and clearer at the same time.

The technician timely divided the main control screen into twelve split screens.

These twelve split screens included the four major orientations of the Celestial Palace, close-ups of the Array, clusters of collapsed buildings, etc.

However, due to the dim light, many distant scenes still appear blurry.

Such as the light source.

Even though Academician Pan had already maximized the power, it's still unclear where the light is coming from.

Nevertheless, from the numerous images transmitted back, one simple thing can be analyzed.

That is, the area of this Earth Palace is probably not small, with a length and width of at least three kilometers.

Much larger than the few hundred meters squared that the Rabbits had previously estimated.

Although the area of the Earth Palace is unknown, its height is not difficult to determine.

The top is about a hundred meters high, indicating that this space is unlikely to be as hard to measure as the pit of Qian Gu Mountain.

Subsequently, Academician Pan tried enlarging several images and finally confirmed three very clear images:

The first image is naturally of the cyclone entrance.

It's somewhat strange to say the least.

The entrance outside is a cyclone, while the interior has a square green mark about five centimeters in length and width.

Moreover, the cyclone's orientation on land is obviously facing the ground, but the mark is on the side of this space.

That means the ground of the space is perpendicular to the land's surface.

The center of the mark is carved with an odd character, somewhat resembling the letter ༂.

Academician Pan thought for a moment and said to Wei Fan:

"Clan Leader Wei, could you take a look? Do you recognize this mark?"

Wei Fan glanced at it a few times, shook his head:

"Sorry, I've never seen such a symbol, but perhaps you can ask Qiangsheng; he's much more knowledgeable in this field than I am."

Academician Pan nodded slightly, thanking him.

This was just a casual question, so he wasn't too disappointed.

Then he shifted his attention to the second image.

The second image is of the collapsed main structure of the palace.

This palace is located a kilometer directly in front of the entrance, making it hard not to see.

The original height of the palace is unknown, various ruins and broken walls are collapsed and heaped on the ground, a sight of desolation.

But from one of the load-bearing columns that hasn't collapsed, its original height should be between twenty to thirty meters.

The third image is of the Array about ten meters in front of the palace, the only suspected functioning object in the Celestial Palace.

The Array is about five to six meters wide, with numerous runes engraved around it.

Some of these are still emitting a crystalline glow.

Unsurprisingly, this should be the legendary grand Array 'beneath' Qingcheng Mountain.

The beryllium ion channel could gather only this much information, and then Academician Pan returned to the ground.

As soon as he landed, Lin Ziming approached:

"Academician Pan, do you have any way to open the Celestial Palace?"
