Chapter 153: Attrition Warfare

After dozens of seconds of feeling like levitating, that feeling of floating suddenly ended, and the hard ground peculiar to a dungeon appeared before us. Yes, we're thrown there.

"Hop"

I immediately adjusted my position in the air and landed. When I look at the surroundings, the other adventurers were also able to land safely. However, those who don't have status had fallen on their stomachs and backs. Still, since they didn't seem to be injured, I am relieved.

When I was thinking about that, Rei came to my side.

"Rin, is this, perchance"

"Aa, this is without a doubt a dungeon outbreak"

"But it's strange. There is no way a dungeon could emerge on the ex-site of another dungeon. Even if there is, it should be at least a year after the collapse of the said dungeon."

It was exactly as Rei said. Moreover, that's not the only strange point. As the research about dungeons progressed year by year, even if we couldn't prevent the outbreak of the dungeon itself, it became possible to make it happen in a place with few people and buildings. For that reason, in the last few years, there have been no incidents about people getting involved in a dungeon outbreak.

Despite that, now, we're involved in a dungeon outbreak. This continuously irregular situation gives me a headache.

"Although I don't know why we're involved in this, as we're inside a dungeon, monsters will be attacking us at any time. Thus, you should change into your equipment."

"Understood"

Hearing my words, Rei nodded. We, who had been hanging out until a while ago, are now wearing everyday clothes as a matter of course. But, as long as we have our equipment stored in [Item Box], we could change into it in an instant, so we are going to make use of that function.

I usually use it when I go in and out of the dungeon but I never thought that I would have to use it after entering a dungeon like this.

While we're changing our equipment, Yagami-san and his party have already changed into their equipment. Then, I turned my gaze to Yui and Hana who were nearby.

"Do you have Item Box, Yui?"

"Yes, I acquired it a while ago!"

"Then, I'm relieved for the time being. But, if I remember it well, I think Hana hasn't acquired it yet."

"If it's a coat that I used to use, Hana should be able to use it too. I will lend it."

"Thank you very much, Rei-senpai!"

Right after that, the body of the three of us, excluding Hana were enveloped in a faint light. As a result, now, I was wearing a black coat with a red line. Rei was wearing a white combat uniform with a blue line, while Yui was wearing a white and pink robe. By the way, Hana also wore the coat she received from Rei.

Now, we've finished doing something that we should have done at the very least. And regarding how we should move from here, I would like to discuss it with Yagami-san. So, with that in mind, I headed toward Yagami-san who was a little away from me. But, at the next moment.

"Rin-senpai, look out!"

Yui's scream echoed in the area. Promptly after that, something black jumped up from the shadow of my feet, and a sharp jet-black knife flew straight to my throat but

"You are in the way."

I swung Greed with my left hand and cut it in half in a flash. With just that, the mysterious monster was killed. And from what I felt when I cut it, I think it was around level 20,000, which showed that this dungeon was at least A-rank or higher.

"Eh? Eh? Just now, what on earth"

Looking at that scene, Yui displayed an expression that said she didn't know what just happened in front of her. Well, it is something that couldnt be helped as Yui didn't know about my true abilities. But now, I don't have time to explain.

"Hana, Rei. Help Yui for the time being"

"Un!"

"Alright."

I asked the two to explain to her so that she would not be confused. Then, after using [Enemy Detection] to check whether there is another monster in the room we are currently in or not, I headed to Yagami-san's party, which had strange expressions on their faces.

"Amane, huh. This surely has become troublesome. Do you know how strong the monster that attacked you just now is?"

"I think it's around level 20,000"

"It is at least A-rank or higher, huh Which means, bringing the others to the surface just like this doesn't seem realistic"

Then, me and Yagami-san directed our eyes to a certain direction. There stood 60 ordinary people who happened to be in the park and near it who got involved in this incident with us.

"What?! What on earth just happened!"

"Isn't that obvious! We're swallowed by a dungeon!"

"You mean monsters will be attacking us?! We will die here?!"

The sudden course of events made everyone there lose their cool and began panicking. Well, even us, who were always diving into the dungeon, were confused, so it would be unavoidable for them to feel confused.

" Looks like we have to calm them down first"

"It appears to be so."

"Although the fact that we're in a predicament doesn't change, at least the presence of us and Amane here could be called a saving grace. This means, there is still a slight chance that everyone could survive."

" Our presence here is a saving grace?"

"? What's wrong?"

"No, nothing"

While shaking my head, the words that he said made me feel uncomfortable. At the same time, I remembered the murderous intent that I felt before we're involved in the dungeon outbreak Is it really a coincidence that we are here?

I indeed harbored some doubts, but there is no way to confirm it. Thus, for the time being, we decided to calm them down by letting them know that the members of Yoizuki, which is a famous guild, were here with them. Then,

", this is?!"

"A horde of monsters?!"

The sound of marching echoed throughout the area, which was strangely similar to the monster parade that we experienced in Onizuka Dungeon.

There are two passages connected to the room we are in right now. And we could perceive signs of numerous monsters coming from both of them.

"I guess we should do something about the hordes of monsters first."

"Indeed. Yagami-san, please handle the other passage,"

"Don't tell me, you are planning to stop the other one by yourself?! There are at least 300 monsters you know?!"

In response to his words, I nodded. To be frank, in terms of level and experience, I am not confident I can cooperate well with them. That is why, it would be easier to deal with all the enemies alone.

Summoning Flashsword in my right hand and Greed in my left, I assumed a dual-wielding stance. Rather than using Nameless, this method is easier to fight lower-level enemies. And looking at this, Yagami-san seemed to have made up his mind and nodded.

"Understood. I will leave the other to you. Do call for help when it's getting dangerous."

"I know."

After such an exchange, we started an attrition warfare against a large number of monsters.
