After a briefing at the school on the first day, they were gathered in an auditorium-like building to hold the entrance ceremony. I don't usually meet 2nd and 3rd graders.

Second and third graders have slightly different uniforms. It seems that the uniform design is slightly changed every year.

The school has many large buildings, several auditoriums and open spaces, and is quite large. I rarely meet at the cafeteria, so I wonder if there are multiple cafeterias.

The hero and the president, but have not met since then. The King of Spirits said a lot about it, but I don't know what it is at this time.

If there is a harvest in the appraisal ceremony, the hero was in normal mode. And there was almost no Hellmode in this world. If you enter Hell mode, you will be in a world where you can get all Es even if you have the ability value S. Elves who have lived for 1000 years say they have never known. Moreover, the current president has not changed since the school was established. You may be able to say that you have seen hundreds of thousands of test takers, but you have hardly ever seen them.

Allen goes to the school, so he will tell you if there is anything.

The classes at the academy are general education for one year, but there is a class called Demon Beast Research. What I'm telling me now is the ecology and activities of goblins and oaks. I think it is a unique class in a different world. The instructor eagerly teaches how to defeat, weaknesses, and points to note.

In the afternoon, what you do with your talent is different, but there is no lesson for Allen's talented summoner. When I talked to my teacher, it was said that there should be no exams, so I should take classes appropriately. Apparently it was good to do some research in the library and it was quite appropriate. I am taking classes such as swords and magic. For now, I'm going to take classes.

The school has four days and is closed for two days. Two of the six days a week are closed, so it feels like it isn't very packed.

On the morning of the holiday after the school life on the 4th, Allen and his group are in front of the dungeon.

The challenge today is C-class dungeon. E-rank adventurers, Allen and others, can only enter C-class dungeons.

The dungeon, which looks a bit far away, seems to be a large building. The reason why we look a little further away is that there is a queue. In front of you is a long line that seems to be an adventurer in armor. It seems to be crowded in the morning.

(Is it about 3 stories? I heard that the C class dungeon is about 4 to 6 stories, but the building is quite low. It is halfway to go up, is it a dungeon of dive?)

As Clenna gladly looked through the window of the mage boat to see the school city, Allen was checking how the dungeon existed. I don't think there is a building with 10 or 20 floors, so I think it's a dungeon dive underground.

"Dungeon!"

"Oh, dungeon!"

As they line up, Klena talks to Allen while exhilarating. Allen answers with a smile.

"Why are you so happy?"

"..."

Tsukkomi enters from Cecil. Dogola is still on the sidelines.

After a while, the turn came.

"Is it like a student? Do you have an adventurer's card?"

All four show their adventurer identities as told by the person in charge of the dungeon. The equipment looks good, but he is told not to overdo it.

This time it cost 200 gold coins for the three people. Mythril's ax and great sword are 100 gold coins. And Cecil, an ancient tree wand and three armor. Gold coins are decreasing. Right now, there are about 200 gold coins remaining.

Clena seems to like a pretty big sword.

"This is my first dungeon. Should I get into this?"

"Oh, yes. It's my first time. Then I often ask questions. Look, go to Room 205."

"Yes, I see."

(Question? Room 205? I was told something like an apartment. Did you think you came to a dungeon but did you come to an apartment?)

Allen asked a lot of questions in the Adventurer's Guild about difficulty, available items, and more. I thought that if I gathered the equipment and knew the strength of the monster to some extent, I would manage to do the rest, but I noticed that there were many things I did not know yet.

There are also several sets of adventure parties carrying trolleys. It seems to be able to climb to the upper level in the form of a slope. Other than weapons and armor, I only bring things that fit into storage skills. There are lots of storages, such as light magic tools, food, and camping sets.

There were several large doors on the first floor, but there are also many rooms on the second floor, and doors are lined up along the passage at equal intervals.

Open the large door labeled Room 205. It is likely that large adventurers and bogies will be available if they are reasonable.

Opening the door of the room, the first thing that jumped into my eyes was a Rubik's cube floating in the air. A large cube, one meter or so on a side, floats in the air. It flashes in red, blue, yellow and various colors, and is ticking like a Rubik's cube.

"Please close the door once you enter."

"""Talked!"""

Everyone was surprised to hear the Rubik's Cube floating in the air. Close the door as told and gather in front of the cube floating in the center of the room.

"Please show your adventurer ID"

Despite the surprised Allen, they keep talking like a mechanical sound, a crunchy conversation like an old anime robot talks. In some places the conversation breaks, but it doesn't seem that people are talking.

For the time being, they don't progress even if they're surprised, so they show their adventurer's identities to this elusive one.

"Allen, E, Clena, E, Cecil, Eg, Dogola, E? 』

"That's right"

"Welcome to Class C dungeon. I manage this dungeon, dungeon integrated operation management system C205]

(Well, how does the dungeon management system look visually? I don't know how to do it, but it's elaborate.)

"I'm sorry, this room seems to be a dead end, can I go to the dungeon from here?"

"exactly. I will guide you to a dungeon on another dimension "

"Another dimension? Isn't the mackerel different?"

(It looks like an instance dungeon.

Allen's online game had a dungeon created at each party, often called an instance dungeon. Listening to the explanation, it is a style similar to that dungeon.

A mackerel is a server. The reason I was told that the dimensions were different was that when Allen was playing games in the previous life, servers often differed depending on where in the game. It is common for servers to be different in cities, fields, dungeons, etc. to reduce the server load due to congestion.

Recall that all instance dungeons were separate servers with isolated spaces.

"Are you a mackerel? Sorry, I did not understand '

"No, I understand another dimension. I want to go to the dungeon so I want to skip it."

"OK. In addition, it is the first dungeon when I check the record of the adventurer's card. May I explain dungeons? 』

(Huh? Is there still an explanation? Do you have friends and ask them?)

Allen liked to learn as she did rather than get a firm explanation. If you don't know what to do, check it online. However, this time there are friends and I want to reduce my danger.

Continue conversation with C205 seriously.

"Please explain"

Clena is excitedly watching the conversation between Allen and C205. Cecile looks at why he can talk with ease.

"The dimensions that are skipped are different depending on the adventure party and the room in which the room is located. No other adventurers will come, so no help will come, so please be prepared! ''

"Ooooooooooo! It's a perfect separate mackerel!"

"What, what! From a while ago!"

"Don't you know Cecil! I'm saying that the mackerel is different!"

(It's not unlimited summons!)

"Allen has gone wrong. I feel like he was from the beginning ..."

Cecil is stunned by Allen's reaction.

Then, just in case, ask questions about how to return, trap, how to go to another level, conditions of dungeon capture etc.

If the dungeon boss is a C-class dungeon, a C-rank monster seems to appear. Monsters other than the boss are E-rank and D-rank monsters.

I've heard the story, so I'll jump straight to the first class of the C-class dungeon.

"So please do your best"

In that case, the field of view changes from room 205. The room remains the same size, with C205 floating nearby but open front. The road is ready.

Allen looks around.

"Is it in the dungeon?"

"It looks like that."

Dogora answers Clena's question.

"Okay, it looks like one level in the dungeon.

Everyone nodded, and Allen and others went into the dungeon.
