Volcanic field from the 26th basement to the 30th basement.

It's a field surrounded by rock-skinned walls that can mine ore, just like mine fields, and walk down the road to the back, but the difference with mines is the magma of volcanoes gushing from all over the aisle.

It is a dangerous substitute for melting in an instant, such as a person's body, if touched, and because of the heat emitted by the magma, the volcanic field just gets steamy and sweaty when there is one.

And the basement 27th floor that came was a little different.

The place transferred from the 26th basement floor is stretched with serpentine paths to the left and right, with a structure aimed at the deepest 10 km away while diving into a cave along the way.

However, a course exists that can only be shortcut on the 27th basement floor.

That's Magma's rapidly descending.

"It's a very simple boat."

A river of magma flows straight from the front of the entrance, the metastatic crystal, so that it can be reached in one kilometer to the deepest part of the 27th basement floor, just as it was when it took the left and right paths normally along the stream.

The boat to go down the river was prepared by the labyrinth.

It is not a normal boat, of course, because it goes down the river of magma, and it cannot be dissolved even if it flows over the magma in a special boat built using special metals that can be collected in the labyrinth.

The boat was built so large that there was no problem with ten people sitting down because it was meant to carry the party, as Illis said, but it was a boat with no decorations at all.

"Don't complain because building this boat consumes the magic of the labyrinth."

Get in the boat. Sylvia and the others follow me.

The moment they all got in, the boat rocked slightly, but not because the last Melissa they got in was heavy or anything, but because that's the specification.

"It's the first time I've ever gotten in just listening to you, but five people just got in and you're shaking."

"That sounds more interesting, doesn't it?

"Sounds interesting..."

In fact, the rapid-flow magma on the 27th basement floor was not created for adventurers who visited the labyrinth to prepare shortcuts for the course. It was an attraction created in his spare time by the then Labyrinth Lord (Dungeon Master), who had too much power.

Stand at the tip of the boat making sure everyone gets in.

We just need to be cautious because if we fall into the Magma Sea, we won't be safe.

"Let's move it."

"Shah."

Moves forward when magic runs through the boat.

"You're setting directions in response to the will of the human being who's running the magic."

"Want me to move it?

"Yes."

entrust the operation to the United Kingdom on behalf of the lead.

Operation, even if said, can be manipulated by anyone as long as they have the magic manipulation capability necessary for the operation, as only the degree to which they are required to move to the left or right side and what speed to do is required.

"Look, it's a turtle."

Sylvia looks out at the sea of magma as she sits on a boat in a relaxed manner.

Turtles face from the sea of magma. This turtle - the flare turtle - also lives in a demonic, volcanic, hot place, a large turtle bearing a burning methyl on its back.

I'm spitting out a chunk of magma.

Raise your un-female voice as Ira looks at the flare turtle in the same way.

A mass of burning rock spit out of the flare turtle approaches the boat.

There's nothing like breaking in a single blow, but if you've had a bunch of shots, your boat is starting to break.

"By the way, when you explore the 27th basement, you need to be alert to demons that suddenly appear from the sea of magma and prepare for the attack."

"Please say that quickly!

Beat the magically created ice column on a magma bullet as Illis screams.

Magma and ice collide and water vapor can stand around.

A flared turtle escapes into the chilled air generated. Flare turtles have the nature of being vulnerable to cold air and water, so they tend to escape when they feel there is imminent danger to them.

"What other demons are there?

Iris asks me to check first because it's dangerous to fall.

But demons aren't the only ones in danger.

All of a sudden a magma erupts from the sea of magma and hits me like a snake.

"Icewall"

Melissa's ice walls, which let her out in the air at speeds higher than those of Illis, take the magma.

A wall of ice that is melted but receives magma falls into the sea of magma.

"Watch out for natural traps, as they can come at you."

"Why, it sounds like so much fun!

It's actually fun to taste just the right tension.

I can see the feeling that the labyrinth lord of the time made of boredom.

Even then, running the boat, a man-made demon made of magma - a magma man or a magma shark, a magma shaped demon, has been attacked, but it has all been repelled by the magic of Illis and Melissa.

Unlike on the ground, long-range means are required because they have to attack enemies coming from the top of the boat.

Sylvia and Ira also have knives and bows that fly away as a means of ranged attack, but the physical attack is swallowed by Magma's body and is not an effective means of attack, so it is left to Iris and Melissa.

I was enjoying the presence of enemies jumping out of the sea.

Such a pleasant journey will also come to an end by the time ten minutes pass.

"It's time for the event boss."

"Event boss?

"Are you different from the boss that emerges on the tenth or twentieth floor?

At the deepest end of each field exists a boss with mighty power.

Many adventurers are haunting their heads because they can't move on to the next tier without defeating the boss.

There's a different boss than those bosses.

The sea of magma rose, and from inside there was a dragon with a long torso, like a snake with a bright red scale.

This is the last trial of the rapid-stream magma.

"What is it, level 200!?

I was surprised using the appraisal. Illis screams.

A level of demon you won't see outside the labyrinth at all - the Magma Dragon.

At this level, it is beyond the strength that a normal human being can defeat alone. It's strong enough that if it emerges on the ground, the country needs to stand up to it even though it makes a total sacrifice.

Ma, I can take it down if I'm the labyrinth lord, but it's hard for a family member to have only 20%.

Magma Dragon throws up flamebullets.

"Hih, left!

Turn the boat's direction of travel to the left as Illis puts it in his mouth.

Seems more in a hurry than I imagined.

"Don't worry, he's not going to attack me for real."

"Reason!?

"He came down the magma. The goal is to block the path of the other guy and make him turn back. So it's easy to avoid attacks depending on how you stand around."

"You don't have to say that!

However, Illis continues straight ahead as he moves the boat to the left and right.

If you stay like this, you will receive the enemy within ten seconds.

"I have no choice."

Illis flies off the tip of the boat, snuggled by flaming bullets coming down one after the other.

- What?

"Absolute Zero"

Flame bullets spit out of the Magma Dragon are frozen in an instant, and the body of the Magma Dragon is frozen from everywhere.

GYAOOOOO!

A frightened magma dragon growls at her frozen body.

The magic used by Illis is the magic used by the boss on the 75th floor of the labyrinth, an absolute zero degree magic that freezes moving objects in a certain space and stops the opponent from moving. The quicker you deal with this magic, the more frozen the object will be, so you will take down the opponent after suppressing as much movement as possible. Magma's dragon body was always a shaky magma, so it was impossible to suppress movement.

It is classified as the finest magic, and it has a matching effect, but during activation, there is an amount of magic from the United Kingdom that is dependent on it to continue to consume magic abnormally, and it can only be used for 25 seconds. Besides, I've consumed my magic power by the time I get here, so the limit of time I can be activated is ten seconds.

Ten seconds of the limit goes by.

Iris falls as he stood frozen the air at his feet while in the air.

"Oops."

Not if you're looking at magic that's rarely seen.

Take the Illis that falls by manipulating a boat that is no longer manned by those who shed their magic by the fact that Illis popped up.

"Were you able to defeat him?

"Naturally."

Let them stand on their feet with their shoulders supported because they don't seem to see their magical results.

Around, even the sea of magma has frozen as well as the magma dragons that have been attacking us.

"It's a tremendous magic of power, but the magic is activated until the magic runs out because it's too powerful to control. Besides, it can only be activated for a short period of time even if it has a magic power of more than 5,000, so in the future, think about the situation and use it."

"... Yes"

Iris nodded at how he reflected.

That's as far down as the rapids go.

The boat was also unable to move because it was freezing because it was within the range of Absolute Zero's effects. It will be dissolved by the ambient heat in a while, but not in such a situation that it can move quickly.

"I'm not going to be able to explore any more, and I'm going home for today"

"Right."

Three people stand up who were also sitting while the Magma Dragon attacked them.

I'm not nervous because I can afford to intercept demons and magmas when I get on them, but I was nervous and enjoyed being on a boat that someone was operating. Now let's get you on a boat that Melissa drives.

I was turning bright red when I saw the face of Illis in front of me trying to get home to the mansion.

Magma's enthusiasm is still there, so I thought it might be because of it, but it wasn't.

Looks like he's turning his face bright red in the light because I'm holding him.

"Oh, I'm sorry!

Iris leaves me in a hurry.

These reactions were not seen by Sylvia and the others, so they are fresh.

"What do you want to do? Should we react like that?

"I don't think you can, though."

"It would be counterproductive if we did it"

My three daughters are saying something.

I would like you to stop because I am wary and restless that it is a trap to have a herbivorous reaction from a carnivorous woman right now.

"Look, we're going home"

When I returned to the mansion, I slept well on my own that day.
