Boundary Labyrinth and the Foreign Magician

Spacious space. Enough passageways for even teal to come and go and holes with mouths all over the place. The aisle overlaps in 3D... and it's definitely a shaped fit. The walls are slightly smoother. It seems that the currents flowing in from somewhere have eroded.

It's just that the currents outside are steep, but not so much inside the cave.

Higher water transparency is helpful...... it would be better to keep life instruction because there are so many blind spots.

The internal movement itself is not so difficult...... after all, care will need to be taken not to get lost.

"I wonder why such a cave was formed?

Osgrave says by doing his hand to his jaw.

"Right. If it's land, the rain melts the limestone beneath the ground, forming a cavity little by little... Since the formation of the cave, it has sunk to the bottom of the ocean due to crust fluctuations, the effects of flowing currents, or as a result of the activities of some creature or demon…"

I can't tell you how interested I am. It's just... even if one of the speculations had hit me, I don't know if I'd find any evidence in this exploration.

Since the purpose of this one is not to look for reasons for cave formation in the first place, the priority is low, even if it is of interest.

"Well for starters... let's just leave out how the cave was formed and see how strong the walls, ceilings, etc. are, while moving in the direction of Donna's reaction."

When it comes to it, everyone nods too.

I'll just scrape a little bit of seemingly less influential and let Wiz analyze it - but the moment I scraped it, I saw blue luminescence like sparks scattering. It has a high magic content.

"No, this is-"

Wrapped in dark magic to block magic lights...... Increase the accuracy of life instruction. We saw a reaction like a chisel and a spark like neurotransmission running.

The blue light ran to react when magic flowed over the rock shards in my hand. Wiz analyzes the response that returns.

"... ok. Looks like the cave walls themselves are covered with coral-like creatures. Underwater mountains... melted and eaten over a long period of time resulting in these undersea caves forming...?

"I don't know what that means again... it's magnificent..."

Weltes leaks his voice as he looks around inside the cave.

"If you're a creature that's been on the current, you might find a similar place along the current. Although it may not be suitable for survival unless it is in the same environment as this place. I think it's classified as a coral demon because it's reacting to magic."

Push shards of sharpened rock into their original location and soil magic assimilates the layer of rock beneath the coral with the cave. Is this the way it was?

"So the cave coral itself is layered to cover the interior of the cave, and this has considerable strength. I think the cave itself is getting pretty sturdy, though it's strange that it's internal but exoskeleton…"

"That's a relief."

Wimberg nodded yeah. Right. So there was less collapse. Does the safety level increase somewhat while exploring?

"In any case, the policy will remain the same. We need to worry about fighting to avoid destroying walls and ceilings if we encounter demons. Because the cave itself is formed as a coral, he said, choosing an unaffected way to fight."

If the coral dies, it could become brittle. If you choose a massive attack, you may also find yourself structurally collapsing.

Describing the area as a preexploratory mindset, they all nod with a serious look.

"Then it's better not to use my awakening abilities. You can make lightning directional even in the water, but when the impact on walls, floors, and ceilings is huge."

Tesdiros said.

"Do you think you can handle it with a normal sword?

"Right. If you don't use your abilities, your physical abilities are fine. Respond without imposing."

Tesdiros answers my question.

"Okay."

I snort too. It is said that you will not be able to move like lightning with thunder, but Tesdiros has had enough experience as a mercenary and will be fine.

Essentially, it's better to respond in melee combat than flying gear. "

Elliot says. I wonder if it will.

In the case of Osgrave, it can move while reducing the impact on the environment, so should it be called the responsiveness of boulders? You can rest assured that you will serve as my lord.

Okay. As for the coordinates - are we going to aim slowly in the lower direction? The entrance where we came in will be a little above the center where the golem was formed.

It doesn't always go straight. I also want to be cautious about drilling holes, so let's be cautious about choosing a route.

First, choose a route that honestly goes downwards. We are slowly swimming downwards through a vertically spreading crack-like structure, while installing a rod with magical lighting in the foreseeable range. The rod part is an impromptu of earthly magic, and although the magic stone is only blurry, it is as simple as a magic prop.

"The interference... Oh. I think I can."

Permeate the coral layer to interfere with the cave walls beneath it. The coral layer is also deformed with the soil by interfering with and deforming it with circulating smell, and the holes are drilled, where lighted rods are inserted and assimilated. It also has no effect on coral life reactions…

"This will make it easier to understand where we are now exploring."

"Right. You should also return to the direction of light when you are lost. When you explore and hit the end of the line, go back to retrieve the lighting and place a different color light at the branch point, indicating that the search is over."

I also have each magic item indicating my relative position to take shipwreck prevention measures, but if I still get shipwrecked, I will deal with it with metastatic magic and summoning magic.

Even if you go back to the airship, the road you pass leaves a lighting rod, so it's easy to explore again if you follow the lights.

"You're thankful for the transparency. I can spread the lighting a little bit."

If you move on for a while and then look back, you can see the shaking lights continue up a little bit. Because we passed by, we can also see the life response of strange fish coming out of the shadows of the rocks.

"As far as life and magic reactions go, strange fish are normal fish anyway. Doesn't seem like you need to be too vigilant."

"So you need to be careful with people who have a big life force or a magical reaction."

Oldia says. Don't be. More caution will be needed because the life response from penetrating the rock seems to become distorted and slightly less visible to the coral.

There are several horizontal holes, but they were proceeding towards the coordinates of the center through a space like a crack spread lengthwise, eventually leading to a protrusion.

"What shall we do?

"There was a big horizontal hole a little back, so let's move on that way"

Waldom also said the route selection inside the cave was not so surprising.

With the aim of building a seal, it would have been necessary to bring its subject here, and the chosen location itself does not already bring people in. There would have been a weak reason for purposefully choosing a narrow path.

Besides... if cave corals eat rocks, caves will expand over time. I don't know how much it expanded from the time Waldom arrived... but then it would be okay to exclude the narrow hole as a route option from the start because it would conclude that it was something smaller at the time.

While explaining those thoughts, we go back a little bit and move on to the big horizontal hole of purpose. The space with the impression of a longitudinal crack gave rise to an atmosphere such as a natural sinus with a different low ceiling when entering the horizontal hole.

According to Donna, it's still a long way to the center. Collapse or shipwreck… and I'd like to proceed with caution while also being aware of unknown but hostile demons.
