Proceed down the long corridor.

At the end of the opening of the entrance to the tower there is a dark corridor without lights, where you can see the light that seems to be the exit in the back.

"This place..."

At the end of the hallway there was a vast circular space.

If you look up, there's a ceiling about 30 meters away.

Given the height of the tower seen from the outside, the ceiling would not be the end point.

"There's a way to get up..."

"There is a spiral staircase on the outside"

The staircase has begun from the wall opposite the entrance and continues along the wall to holes drilled in the ceiling.

I don't want to think about the number of steps.

"That's a hassle..."

I lost my mind climbing when I saw the stairs.

But if you're investigating the inside of the tower, you can't just not use the stairs.

There were numerous doors on the walls of the circular space.

What's inside?

If we're going to investigate the tower, we'll have to check inside the room as well.

And the door is also halfway through the spiral stairs.

I also have to make sure there are no traps on the spiral stairs anyway, so I need to climb.

"What do we do? Split up and explore?

"So is that."

Given the laser earlier, there could be dangerous traps.

Too much splitting is also a problem.

So Sylvia and I can [detect] and split up.

For me, Iris and Noel.

As an adventurer, I will combine it with Ilis, who has the longest history of adventurers, in order to follow up on Noel, who is still immature.

Sylvia and the others enter the room on their right.

We'll have the room on our left from the entrance investigated.

"Warehouse?"

In the room there was a regular line of shelves made of metal.

A worn out container of about fifty centimeters is placed on the shelf. I'll check the contents, but I couldn't know what was worn out and in more than the container.

"No, other containers feel the same way"

"It's pretty old stuff, but I can't smell it. Save it."

Even though I opened the decaying container, there is no such thing as dust.

I tried to get in touch with the group on the other side, but they seem to be in the same situation.

"Does anyone know what this is?

I'll ask him to try, but Illis and Noel are shaking their necks to the side.

Sylvia and the others are in the same situation......

"This container was used to maintain its contents during ancient civilization."

Melissa knew.

"You know what?

'Yes, a rarely discovered substitute in a building that doesn't know when it was built, like this tower, and unlike a poorly placed substitute in this warehouse, if it's in good condition, it's something that can be stored without time passing, just like a storage ring'

Containers with the same effect as storage rings.

Rather than that, it seems that the storage ring was a substitute for researching this container and making it.

'Unlike a storage ring, it may seem ineffective because it can be stored up to the size of the container, but this container is open to anyone'

In the case of storage rings, it is necessary to flush magic when storing them, and thus the user is recognized at that time, so that it cannot be released without the user.

Such disadvantages make no sense if you only have what you store in your own hands.

So we never cared before.

'It seems to be treasured when exchanging supplies in the military and the Chamber of Commerce because of this benefit'

He who gives and receives things.

If it becomes an organization, it will come differently.

"It seems this one is more common for these people than storage rings."

Above all, there is a cost problem.

Because the storage ring also compresses the space, it uses a number of expensive materials.

I can get it as long as I can give you the money. But in order to do that, an adventurer would need to earn the same income as an A-rank adventurer. As a result, small and medium-sized chambers of commerce are harder to reach.

"Above all, I have been successful in generating storage rings, but not in containers."

There are such circumstances and they are not more prevalent than storage rings.

"You knew me well."

'If you're dealing with a merchant, you'll get this much knowledge'

Before I became an adventurer, Melissa had accumulated funds by doing various things with merchants against her.

It wasn't strange for her to know about the container.

"If it's the most ancient civilizational legacy, there's someone more familiar with it than me."

―――――

Everyone's consciousness is directed towards you.

"The truth is, I don't want you to rely on me."

"You know about this"

"Yeah, it's a normal substitute for the times I lived as a person."

Convenient containers that can be made cheaper than storage rings.

Such a handy tool was also prevented from obtaining material by the catastrophe that had existed a long time ago, and technology was lost at some point by the fact that no one was there to make it.

Instead of saying, how do you not know about containers?

"What do you mean?

"Take a look at the labyrinth catalogue"

Calling out a list of magic tools that can be made with the power of the labyrinth as they say.

There are tens of thousands of magic tools alone in the catalogue. They range from magic tools that can be used in everyday life to things that can help you fight.

So being a labyrinth owner, I don't remember everything either.

This neighborhood is just like demons.

"There was..."

Illis, who was looking at the catalog just like me, found it.

"" Box of State Preservation ". It's the same thing we have here."

"How could you not remember?

Noel wonders what I didn't remember.

I remember looking at the catalog and I used to look at it too.

"You can see that by looking at the magic needed to produce it."

I had no trouble with the storage ring for my own use.

I didn't even think about giving it to adventurers who visited the labyrinth, but it took a lot of magic to produce it. I needed adventurers with enough strength to come to the middle class to stay for days when I thought about taking it, but if an adventurer with all that strength sold a "state preservation box," it would only be a bundle of sandwiches.

I was losing interest because I would lose money trying to produce it by magic alone.

"Still, I found out that there was a" state saving box. "

"Right."

"What, what do you mean?

Noel doesn't seem to understand, but the warehouse situation was bothering me and Iris.

The three of us on the other side have the same vibe.

"This container was commonly used in ancient civilizations. And since the catastrophe, the very way it is made has been mourned. This means that the tower... or the ruins themselves were used before the catastrophe."

I am told that before the catastrophe there was a better civilization than there is now.

Then I have to make sure.

"Hey, in ancient civilizational times, did you have enough technology to create cities under the sea?

'It should be technically possible, but you're going to need a lot of technology to keep a city like this alive. I guess I can finally get it done by collecting a collection of pieces of technology from those days?

The best technology of the time.

A substitute, arguably the symbol, is at the top of the tower.

"What. You have a treasure."

I thought it was worth a lot because it was a magic tool that could maintain the bond.

But I found it worth more than I could imagine, and I was smiling naturally.

However, at the same time, she was pregnant with the problem.

"Ancient civilization-era ruins and stuff. It's too much trouble."

He seems to know a lot about the labyrinth nucleus, but he doesn't give me any useful information easily.
