As Orton poured magic power into the magic array in the hall, the magic array of the entire hall was lit up, and a huge stone pillar rose in the center of the hall!

This stone pillar is more than three meters high, and the width is even more than three or five people can not hold together, and when this stone pillar is fully raised, the magic circle in the hall will be extinguished little by little.

"Teacher, this is ......"

It wasn't until all the circles around them were extinguished that Rocky and Karina came back to their senses, and then they looked at the huge stone pillar in front of them.

"This is the door. ”

As he spoke, Orton walked around the stone pillar, but stopped halfway through.

"Come and see. ”

Rocky and Karina, who heard this, immediately came to him, and when they followed his gaze, they couldn't help but widen their eyes.

"Stairs?"

If you look at them, you can see that there is a spiral staircase inside the stone pillar, and from the downward spiral direction of the staircase, it is obvious that it leads to the ground!

I see!

Seeing this staircase leading to the underground, Rocky and Karina finally understood what was going on, it turned out that the real core of the institute was not the building they were in, but underground!

In this way, things are much more reasonable.

Because after finding the diary and reading the contents of it, in fact, Rocky also had some doubts, he always felt that this place was not like a research institute, and continued to conduct research in a mobile building surrounded by demons, this kind of thing would feel unrealistic even if he thought about it, but now it seems that he still underestimated the people of the year, in fact, the people who stayed here back then had already thought of everything, and arranged everything, and the research institute where they were located was just a disguise, even dispensable, and the real core was underground!

And since the most important part of the institute is underground, what good things will be in it?

Thinking of this, the two couldn't help but get excited again.

"Don't think about it, go down quickly, maybe it's just a pile of broken copper and iron. ”

Just as Rocky and the others were fantasizing about finding some treasure, Orton poured a basin of cold water on them at an inopportune time, and then urged the two of them to walk down the stairs up the stone pillar with him.

Walking down the stairs, as expected, it took a long time, indicating that the location of this underground research room is still very deep, and it took more than ten minutes to finally finish.

As their feet finally stepped on the ground, darkness appeared in front of the three of them, so Rocky and Karina quickly turned on the lighting system of the battle armor, and from the eyebrows of the white demon's head, a bright light appeared on the shoulders of the Valkyrie battle armor, although it was not very strong, but it was enough for them to see what was in front of them.

Looking along the light, the two of them found that it was still pitch black in front of them, and the light did not dispel the darkness, and they still didn't need to figure out what kind of place this was, was it a research institute, or a research room?

"What is this place?"

Where......

Place......

Square......

When Karina said this sentence in confusion, she was surprised to hear one echo after another!

It's just a sentence, and it's not a very loud sentence, but it triggers such a long series of echoes, what does this mean?

It means that this place must be huge!

At this moment, the light suddenly appeared, at first it was just a dot, but soon one dot after another spread into a piece, and the darkness was dispelled in an instant.

It turned out that when the two of them couldn't figure out the situation, Orton had already found the location of the magic lamp, no, it should be said that it was the magic lamp, and used the magic power to activate it.

And it wasn't until all the magic lamps were lit that Rocky and the others finally got a full view of the place.

The place they came to was not a research institute or a research laboratory, but a huge factory!

The area here, literally hundreds of meters, is an incomparably huge factory, so it only echoes when you speak, but it is not empty, on the contrary, there is a huge guy here!

"It's ...... What is this?"

"Oh my God......"

When the lights came on, Rocky and Karina first looked around, and then they were caught together by a behemoth in the center of the factory.

If you follow their line of sight, you can see a huge fortress, this fortress is more than ten meters high, huge like a small building, and there are a large number of cannons on the fortress, and the barrels of each cannon make the fortress look like a huge hedgehog, which is extremely exaggerated.

The two people who saw this fortress were instantly stupid, they thought that they would see the research of the Ten Thousand Kingdoms here, but they didn't expect to see such a big guy.

Don't...... The research conducted by the kingdoms of the whole country with all their might...... Is this the thing?

It took them a long time to research such a fortress?

While the two of them were dumbfounded, Orton had already walked in front of the huge fortress, and when they saw this, Rocky and Karina also flew over and came to him.

"Teacher, what is this?"

Looking up at the big guy bigger than a battleship, Rocky couldn't help but ask.

"I think that's the research mentioned in the diary. ”

"That's it, that's what the kingdoms are studying, what can this thing be for?"

Hearing this, Karina couldn't help but look at Orton, and her words showed obvious disappointment.

What an invention is such a hedgehog-like fortress!

"It doesn't have to be ......"

But as soon as she finished speaking, Orton shook his head, and then pointed with his finger: "Look, this thing is made of steel." ”

"What?"

Orton's words made the two of them look at the fortress at once, and sure enough, they found that this thing was indeed not made of stone, but made of steel!

"That's too much of an exaggeration......"

Perhaps it was because they had lived in the sky for so many years that people now always believed that minerals were an incomparably precious resource, so when they found out that this siege was actually made of steel, both of them gasped, and they couldn't help but sigh, I'm afraid that only people in the land era can be so extravagant and wasteful.

But when the emotion passed, they felt disappointed at the same time.

Obviously, the big guy in front of them is a new invention that the kingdoms are researching, and they must be trying to use this steel fortress to defend against demons, and this is precisely the disappointment.

Because even if this fortress is made of steel, it is only a fortress after all, and history has fully proved that it is impossible for demons to be stopped by a fortress, not any fortress.

But just when they were disappointed, Orton said beside him: "Don't be disappointed, look at this, I just found it." ”

As he spoke, he casually handed over a piece of information to Rocky, and Rocky and Karina, who took it, were stunned, and then immediately looked down.

The two of them bowed their heads at the same time, and then they saw a few big words on the information at the same time: "Moving Fortress Plan." ”
