After Sinaya, Sulla, and Karin entered the dungeon, they didn't have time to think about what was inside. If they hesitate and don't go in, they'll freeze to death outside. Anyway, both horizontal and vertical are dead, so it's better to fight.

After the three of them came in in a hurry, they felt a different gravitational trend from the outside.

It's not as good as the feeling of being oppressed by the sea. Dive...... Especially in deep diving, under certain circumstances, the pressure and gravity of deep diving operations are very large, so that Sinaya's underwater movements are very difficult. It was a kind of oppression, tight, binding-like locking up of their bodies and movements.

To be honest, if you don't have much experience, ordinary people are afraid that it will be difficult to bear.

But even a veteran of his kind can't stay in such a deep sea cold situation for too long.

After all, people are still people, not robots.

Miraculously, this feeling suddenly disappeared after entering the dungeon.

The weight on their bodies was completely removed, and their bodies returned to a relaxed and natural state. So much so that with a snap, the three of them fell.

Yes, it fell.

This is the peculiar place, that is, there is no excessive weight required in this underground palace, so that the three of them fell down.

However, not only is there no weight inside, but the sea water outside has not invaded it at all.

In other words, it is an enclosed space that is completely separated from the outside.

Sinaya began to monitor the air quality around her, and found that it was as pure as the water outside.

In other words, the air quality below 20,000 meters below the sea floor is better than the air quality above.

And Sinaya also found that the air in it will be purified and replaced to a certain extent.

Since the air quality is so good, then there is no need for them to waste oxygen, and they directly opened the oxygen mask. Taking a deep breath, I found that not only is the air quality good, but also the temperature outside.

It was almost absolute zero outside, and even if Shinaya had the equipment to prepare everything and thought they were foolproof, they still couldn't hold out in such a terrible cold for more than half an hour, not even half an hour!

But it's warm inside the dungeon, and the temperature here should be about twenty degrees above normal body.

The normal temperature made the three of them slowly adjust their body temperature.

Not to mention that the three of them felt surprised, even those who were also connected to them and observed from the outside would inevitably show a look of surprise.

After all, the difference between the inside and outside temperature is several hundred degrees!

Although there was some surprise, I was able to recover quickly. At the end of the day, some things are good or bad, but the most important thing is that they have to be rare and weird!

It's nothing more than the influence of the ambient air, as well as everything that appears in front of you when you enter this dungeon.

From the outside, this dungeon is all made of ice, and when the entrance switch of the dungeon was opened, the three of them touched it and found that it was indeed the texture of ice.

And after entering the dungeon, I found that the inside of the dungeon was also ice.

In other words, this underground palace is made of ice from the inside out.

Then strange places appeared. If this dungeon is full of ice from the inside out, then why is it that the temperature inside is as high as 20 degrees Celsius without causing any ice to melt?

Not only does it not have the slightest trace of melting, it looks ...... It's pretty sturdy.

The three of them briefly walked around the neighborhood and found that this was the case.

Sinaia realized that it must be due to the temperature of the seabed. Of course, this is not entirely justified.

Sinaya thinks it has something to do with the special building materials here. That is, the ice here ...... It should be a bit of a problem.

Shinaya, Sura, and Karin observed and scanned in three different directions. They were overjoyed by the region beneath the depths of the sea, so desperate to get more of the secrets of this great miracle.

The interior of this dungeon is also amazing.

It was a surprise that was deep in their consciousness.

In the Old Earth period, there was no shortage of tomb robbers.

If there is no shortage of tomb robbers, there will naturally be no shortage of tombs that have been robbed. After all, you can't let a tomb robber return in vain, can you?

Although they are not genuine tomb robbers, they are not necessarily scientific researchers who have never seen the world. On the contrary, they have seen a lot of various 'things' because of their research. Among them, there is naturally no shortage of 'tomb robbing'.

Of course, there are many different forms of so-called tombs.

Earthen cave tombs, stone chamber tombs...... In addition, there are also mausoleums that exist at the bottom of the sea, or in snow-capped mountains, continents, or even in mountains.

In the hands of skilled craftsmen, there is almost an endless stream, and the underground palace where they are now is not completely designed according to the mausoleum.

The ordinary mausoleum is divided into a tomb passage, a front room, a side room, a back room, and a main coffin room......

Not counting those mausoleums with more responsible structures, ordinary mausoleum structures should also be well understood.

It was because they knew the basic structure of the burial chamber of an ordinary mausoleum that they were able to be sure that this place was not entirely designed according to the mausoleum.

After the three of them groped and rested on the spot for a while, they were eager to explore the entire underground palace.

In addition to finding the source of the vital signs in the dungeon, I have to admit that this place is still very interesting for them.

Because of the peculiar architectural style, they couldn't tell whether the design style here originated from that dynasty or what design principles or so on. But if you judge it by style, it's a bit inappropriate.

The style here is similar to variety, but there is no point in the point. It may seem like a casual style, but the architectural pattern here is very exquisite. environment, and institutions.

Of course, if there is no delicate mechanism, how can it be possible to easily change the air in the entire dungeon? Obviously, some of the secrets underlying this place were still not known to Sinaya.

As the three of them went deeper into the interior of the dungeon, the surrounding environment began to change. After walking for a while, they found that the buildings here were unusually ...... Huge.

At first, they thought it was their own illusion, but the height and width of the corridor were very exquisite, as if it was a place specially designed for giants. It was only after the hindsight that they realized the mystery of this place. This is even more like the castle where Shinaya, the rich people, the eldest young master and the young lady live.
