Approximately 3,000 years ago, when we came to see the base "Brave Force Research Institute" used by nine brave men, we decided to build a villa for everyone on the ground at the suggestion of the Duke of Euphemia.

Everyone was so excited that suddenly a meeting started and a plan was made.

The architecture itself will be ready soon if you use "house magic" and so on, so I'm going to visit again tonight and make it.

Once we had the building on the ground, we decided to open a communication passage with the underground base space that had been there before.

Therefore, I decided to confirm the location where the passage was previously located.

I checked with Fumina, the former "Guardian Warrior", Hina, the former "Healing Warrior" and the ancestor of the vampire, and Emeraldia, the fourth princess of the "Machimagna Fourth Empire" who fought with the "Warriors" and who is now the Funeral of the Ship.

Looking from the top, the Heroic Power Laboratory is shaped like glasses with two large circular spaces connected, but it seems that the communication passage was connected to the circular space on the sea side.

The circular spaces on the ocean side are the ones that were not hidden.

There is a circular space hidden in the back.

The former was known as the "open zone" and the latter as the "secret zone".

One of the many rooms built on the walls around the "Open Zone" was like a magic elevator that connected to a castle on the ground.

It appears to have an auxiliary spiral staircase.

I was guided to the room where it was, but it was quite a big room.

I saw it when I first came here, but I only had the impression that some of the walls had collapsed in a large space.

Apparently there was a magic elevator and stairs in the collapsed part.

Emeraldia's prediction is that they destroyed it to prevent intrusion from the ground.

Perhaps when we quickly retrieved this base, we blew it up to prevent intruders after everyone had left the ground.

Once the debris is removed, the passageway to the ground should appear, so I will install a staircase.

I really want to make something like the magic elevator that was there at the time, but I can't make it with my technology...

"I think it would be nice to make more space and create a device that goes up and down with a hover!Mine makes it! "

Mine-chan, a genius girl from "Dwarf", made such a suggestion, as if she had perceived what I was thinking.

Sure, Mine-chan is good at making hover devices, so if you make a hover up and down vehicle and come down and climb with it, it's almost with the elevator.

It might be good.

"Thank you, Mine-chan. Please."

I thanked Mine-chan, had a few simple meetings, and decided to have him make it quick.

"Hey hey, there's nothing down here, right?I've been feeling something since yesterday...Even with the "subspace detection" skill, I don't feel anything like a sway in space... but I'm curious about something.I jumped over again today... but I still feel like there's something I can't help it.And... when I look at the room with this communication corridor, I feel like there's something more... "

Nia suddenly said that.

Indeed, yesterday, while everyone was setting gear on the ship, Nia was flying around the base alone.

Apparently, he wasn't just playing randomly, he felt something uncomfortable and used his "subspace detection" skills to find out if there was anything else.

"As far as I know, there was nothing else."

Emeraldia answered with her arms up and her head tilted.

"I don't think so, either."

"Well... I never came to this base after the final showdown, but I didn't hear anything about renovations or additions at that time..."

Fumina and Hina also answered with thoughtful faces to trace their memories.

"That's right... I think there's something going on...It's not refreshing... "

Nia can't give up and is flying around this big room.

"Chappie, don't think this place is suspicious ~Don't think Nia-chan's guess is right ~ "

Now that Chappie said so, he made a trick of smelling the smell around the rubble.

If Chappie says so, he may be suspicious.

It's not like I don't trust Nia, but Chappie also found the location of the activation switch when she first entered the ruins.

As Nia and Chappie are feeling, if there's still a hidden space outside, it's probably either... further underground or further back than the 'Secret Zone'.

First of all, I suspect Nia and Chappie are worried about the underside of this communication corridor.

I don't know because the rubble is blocked now, but there is a possibility that there was a contact passage on the lower side.

If I collect this debris in one go in my Wave Storage, space may emerge.

Conveniently, there are only my "bond" members here now.

Emeraldia has already become a member of the Bond.

Mine-chan from "Dwarf" is not a "bond" member, but she is no longer a "bond" member, so there is no problem.

Will you use "wave storage" to remove debris without hesitation?

The Dukes of Euphemia know that I used my storage skills to store meteorites, so there's no point hiding them now.

However... when I think about it, I haven't been asked about it in detail.

Maybe you didn't think you had a meteorite.

Maybe he thinks he erased it with some special magic tools.

Well, anyway, I was worried about something under here, so I decided to use "wave storage" to collect it all at once.

When you collect the current rubble, the rubble above falls down.

Visually recovered the debris before landing on the floor. All debris falling from natural falls was removed.

When the debris was removed, a large cavity was opened.

The space with the magic elevator and the spiral staircase would still be a cavity.

The problem is down here.

Since the debris on the floor is gone, I will try to remove the debris on the floor.

Oops, visible debris has been recovered and holes have spread underneath.

And the debris is even more clogged.

Looks like it wasn't just a floor.

The same space as above is spreading.

This feeling... there was probably a communication corridor down there.

I picked up more and more rubble.

The space that seemed to have been the communication corridor continued to the bottom.

It looks like there's totally another space underneath.

I used my "floating" skill to collect the debris that was floating in the air, but I got down to a place where the debris was gone.

I wonder if he got down about five meters... there's a big room like the one above.

One more thing, it's confirmed that there was space underground!

Nia, who was flying with me, was also very pleased.

Or Nia's big Venus!

I would like to sincerely apologize to everyone for thinking that Nia was playing alone yesterday while they were working.I'm sorry, Nia.

It's kind of near... "Queen Pixie", and it's like a conjecture.

Good job, Nia!
