I don't know how long I walked......

Sean couldn't see the weather's timer in the dark, and it was probably estimated that it should be more than half an hour.

However, there is enough space in this cave that you can't see the point until you go inside, and the surrounding area is as empty as a bunker.

If it weren't for the fact that this was on the plateau, Komori would have even wondered if it was a military fortress before!

"How does this place look like something man-made?" Lucille sensed the anomaly here, the cave looked too much like a dungeon in every way.

"Probably not!"

Sean replied.

If it is said that it was built artificially, it can only show that the scientific and technological strength of the people in ancient times was too strong.

It's a few thousand meters deep underground, and it's good for ordinary people to dig down a hundred meters, but the ordinary dungeon is only at this depth, so what tools do you have to use to dig a few thousand meters below?!!

Now I have seen a lot of historical documents, if there is really such a powerful era, it is impossible to leave nothing, and this is a deserted plateau area, which is not suitable for human habitation for a long time, how can it be necessary to build a fortress here.

Can......

To say no, it doesn't seem so certain.

The surrounding environment always feels like it is deliberately polished, even the walls are very smooth, and it is impossible for something that is naturally formed to be like this, even if it is dug by the giant worm.

If it was the giant worm digging this place, it should be like an earthworm hole, crisscrossing the road everywhere, and it could not have been a single road like this, and it really looked like a bunker.

"But it's really like here!"

"It's a lot like, but I can't think of anyone building a bunker here. ”

To say that it is used to store the wealth of the state?

It seems possible.

Just like in those stories, a certain country is too powerful, and is afraid that its descendants will be retaliated against or destroyed, and when it is strong, it buries its national treasure somewhere and waits for future generations to open it when they encounter difficulties.

This is not only in the story, but also in reality, and it seems that Jagon used to do just that.

But the area here is not ordinary after all......

There has never been a strong ethnic group in the history of the plateau, and even many historians believe that the original inhabitants of the Shata country migrated and had to go to the plateau in order to escape the war in the plains, and the local race was slowly formed.

Whether this study is true or not, it is certain that there were no great powers in the history of the plateau, and it would be too difficult for them to dig underground fortifications thousands of meters underground!

Sean pulled Lucille on.

It's not just that it's as confusing as an underground fortification, it's also a little strange that there's plenty of oxygen.

If you can maintain the same environment as the surface air at such a deep depth, it means that there must be a certain passage here that faces outward, but even if there are other passages, the air cannot be exactly the same as the surface.

It must be some other device.

Sean subconsciously thought it was some kind of magic......

Now the place where the two of them walked was already in the depths of the plateau.

Since it is not easy to move around on the surface, it takes a lot of time to walk through the mountains, but once you reach the flat surface underground, the two of you must be able to walk faster.

It's also a lot closer......

If you follow the distance on the surface, Sean feels that he is probably already deep underground below the highest peak.

That means getting close to what you're looking for this time.

This should be the place where the Ancient Crystals have led you.

"Are we going to where we're going? Lucille sensed something strange too, but didn't think about it that way.

I simply feel that this place should be almost at the roof of the world that the two of them planned to go to before.

It's underground, but it's certainly above!

"This should be the place...... Do you feel that the air here is already the same temperature as the surface? "After all, it is thousands of meters underground, and I felt very stuffy before, but after I walked over, I felt much better.

"yes, that's weird!"

Lucille said, looking around.

It's weird......

"I'm afraid it's some kind of magic, or something with energy. Sean said.

"Is that stone still there?"

Lucille scrambled to pull open his pocket......

"It's still there. ”

Since the shockwave in the previous violent blast had almost destroyed most of the things the two were carrying, and there were not many left, Lucille had sorted out the rest of the things when he was on the ground before, and the purple crystal was the only one that had not been damaged at all.

It looks like it's as good as new, and it feels like it's not affected.

"...... here"

Lucille took him out and handed it to Sean.

In the palm of my hand, there is indeed a cold feeling.

This thing stores a certain power, a power that even humans can't explain, but this power can't be turned on by existing technology or magic, so it seems to outsiders to be a strange stone with cold properties.

Even if you have a powerful ability, if you can't use it, it can only be a stone.

Sean didn't know who had the ability to activate the Ancient One Crystal more than ten years later when he was in the Kingdom of Bashalam, and allowed Shuggoth to cross over.

This is still unknown to Sean.

But this time it would be much better, even if Shogues reappeared with his current strength and was not afraid of any creature, even ancient creations.

The two of them continued to walk forward, and the more they went, the more obvious the feeling of an underground fortress and the comfort of the environment......

It was as if the place had deliberately created a place where people could live, and neither the air nor the environment had the feeling of being deep underground, even if it was on the ground and on a comfortable plain at this time.

Lucille and Sean had gone up to the plateau in thick coats, but now they felt hot.

The surroundings are starting to become more comfortable!

Light gradually appeared in the dark distance.

"There's light over there. ”

"Well, go check it out!"

Sean likewise spotted a place where there was light in the distance.

Like the colorful beams of ice under the sun's light, the dark underground cavern is illuminated as day.

When Sean and Lucille got closer, they found that the reflective parts were all huge crystal blocks, extending from hundreds of underground to high places, even so high that the two of them could not see the top part.

This thing is supposed to lead directly to the surface......

Light is refracted from the outside.

"There's a statue in there!"
