Cheat Majutsu de Unmei wo Nejifuseru

"Look, guys. Today is an underground labyrinth exploration internship. Be careful because internship is the first and last thing that is raw. Because the knowledge and experience gained from today's internship will divide your lives and deaths in the future."

Instructor Nakita, a strangely young instructor in charge of our class, raised his voice.

Fifty members of the civilian class were present in the corner of the building that now manages the underground labyrinth.

The underground labyrinth is built above the entrance, even in the city, with the thickest walls, in case demons can leak out, and there are always knights of rank 3 or higher.

In fact, there are demons coming to earth from underground labyrinths a few times a year, and here the resident knights are defeated.

The job is the very existence of this city, which seals up Erna so that no demons can be found on other lands.

"Bye. This is the search permit for the underground labyrinth. If you lose it, you can't go in there, so be careful. And don't let them get too exposed all over the city, because even being robbed is a routine tea thing."

Instructor Nakita hands out a permit to the students to hang themselves from their necks.

Finally. I swelled my chest in anticipation.

It is no exaggeration to say that you entered this school to get it. It usually takes a year to try to get an exploration permit.

"What if we lose it?

I'll listen just in case.

No matter how careful you are, you risk losing it if you are in a dangerous place like an underground labyrinth, or you risk being destroyed.

Sometimes there's nothing you can do to prepare for robbery if the opponent is in character.

"You can reissue it, but it's a 900,000 var levy. By the way, this price is three times the price traded on the black market. If it's cheaper than that, there 'll be stupid kids who sell it."

"Thank you."

I was strangely convinced when I heard there was a guy to sell. Especially when it's a civilian class, it especially sticks to gold.

"It's costly to make quite a bit. This is subtly magical. When you use special magic, it's easier to rescue people because you can tell from about 500 meters away. That magic is a secret, by the way, because it is abused"

I'll check the permits. I figured out how it works in thirty seconds. I see, it emits the magic of normal humans' unsensitive ultra-high wavelengths. This would be undetectable if you didn't know the species.

But I can tell. If we use this, we will have less chance of being struck unintentionally by humans.

"Yes, shall we then enter the underground labyrinth? Have you got your stuff? We all have water and portable food, don't we? If you don't, you'll die."

Everyone snorts silently. This is my first internship, but I have gained a variety of knowledge from school to this day.

"Then the greatest existential significance of this sealed city. Explore the underground labyrinth"

That's how we first stepped into the underground labyrinth.

◇

"What is it, here, underground but bright, green and absolutely weird"

"Right, that's disgusting. I thought a more underground labyrinth was such a jerk."

We stepped into the basement 1F.

Kuna and Anne shouted at each other.

There, the ceiling is about 5m high, the sun is abundant, the trees are flourishing and streams are flowing.

There are no walls, it's like in the woods.

No matter how many times I look at it, the scenery of the underground labyrinth dares me.

"The underground labyrinth grows using the Elna that produces the monsters. It seems that the landscape reflects the demons and the human mind landscape"

"What a mess"

"But it's easier than diving a cave that's even dark and dull."

Furthermore, the labyrinth changes the appearance and nature of each floor.

For example, up to basement 9F, it looks like it's in the woods, like the current hierarchy, but from basement 10F, it looks like it's in a volcano.

"Yes, I have attention to you all. There are quite a few people who don't think it is necessary to bring in water or food after seeing how it looks. Because the creek is flowing, and the nuts that look delicious are fruitful."

Instructor Nakita nodded as she looked at the students' faces.

"But you can never drink or eat anything in this. To try, you, you."

"Heh, is that me!?

A seemingly weak boy is called.

For once, you took the test here, so you must be quite capable.

"Hey, I was wondering if you could drink this water. This amount should be fine."

Instructor Nakita pours water into about a third of the glass and gives it to him.

"Drink that."

"Eh, ha, yes"

The boy drinks a glass of water.

"Yes, yes, yes, yes, yes, yes, belly"

And he spits his face bright blue, and even with his belly he suffers.

Blue phosphorescent light leaks out of the abdomen. It is evidence that it is being treated by escort.

"This is how this happens when you drink or eat what you have here. So bring your own food and water"

"It's terrible, Doctor."

Somehow, a student who has recovered from the power of shelter complains.

"Haha, I'm sorry, I can't remember until I see these sore eyes. For once, what is in the underground labyrinth is made of Elna... with the power to create demons. Once materialized, Erna is no different than a normal substance, but she has a lot of temper, and that can be poisonous except for demons. The cause of death in the underground labyrinth. They say that water and food run out more than demons, eat things from the underground labyrinth and die, so be really careful."

That would be so.

I want to dive a little to make more money.

However, there are limits to the amount of water and food that can be brought in. It is human sexuality that makes me want to procure locally.

Even if I know with my head that it's dangerous, I get my hands on it.

"But from somewhere beyond Blah Blah Rank 3, they've also become resistant, and they eat and drink flat labyrinth stuff, so that's one wall. If you go that far, you can procure locally, so efficiency jumps all at once."

I smile bitterly. We are now rank 1, so we get sick with some temper, but if the rank increases, we can get rid of it to that extent. That would also lengthen the labyrinth's stay.

... Most of all, I have [purification] magic, so that's possible from Rank 1.

In the game days, it was a hassle to bring in food, so much so that they were eating meat from purified demons.

"Set aside the miscellaneous stuff like that, I think it's time for the real thing. It's a battle against the demons that bothers you the most."

That said, instructor Nakita laughed.

With a nasty grin, I'm sure there's something about it.
