World's Fastest Level up!

『The last boss has been subdued』

『Experience acquired – Level increased by 233』

『Last boss subjugation reward – Level increased by 150』

The system's sound reverberated in my mind as usual.

It seems the number of experience I acquired was quite large because I subdued the level 4000 Orc General. It means, added with the level-up I got from the subjugation reward, my level has increased by nearly 400 levels.

Well, although it was a level that I could obtain by repeatedly capturing the dungeon for a day, the fact that it was something to be thankful for didn't change.

However, truthfully, it wasn't a situation where I could honestly be happy with.

First of all, I shifted my eyes to the other adventurer who was in this place with me, Kurosaki Rei, the only survivor from the King of Unique, who with moistened eyes, looked at me with a quiet smile.

"Rin…thank you, for saving me."

"Aa…"

The reason she couldn't be that happy even when her life was just saved, likely was because everyone but her was slaughtered by the Orc General. Presently the four of them were tragically lying around the boss room.

After that, I had heard the whole story briefly from Rei and it was roughly just as I expected. The only difference was that they died in a bewildered state in front of a powerful enemy at the end.

"I see… so it was like that…"

To be honest, besides the fact I didn't like them from the start, I also think the act of challenging the last boss by themselves without awaiting reinforcements was something unforgivable. Even so…I could never say that I'm glad they died even if my mouth tore apart.

"Please tell me about Rin next. How did Rin come here even though the door of the boss room was closed?"

"Mmmm, that was…"

After Rei had finished her story, the topic immediately turned on me.

When I was troubled about how I should explain, shocking words came out of Rei's mouth.

"–It's thanks to Transfer Within Dungeon, right?"

"–! You know about it, huh…"

I was pretty surprised because I didn't think she already found out about that. However, Rei has said that she had heard about me from Kazami before. So, I think it was natural that she arrived at that answer as long as she knew the words [Transfer Within Dungeon]. That's what I thought, but it seems my shock didn't end there.

"Another question. Can you enter the dungeon even in the re-challenge intermission if you use Transfer Within Dungeon?"

"….I can't."

"I see, so, you can."

"Didn't I just say I can't?!"

I spontaneously retorted with a loud voice. However, Rei just smiled lightly.

"Don't worry, I won't spread it around. I know Rin would definitely have a hard time if people knew that Rin could get stronger in a short period of time after all."

Yep, I don't think it is possible to deceive her anymore. Thus, I decided to give in.

"Thanks for your concern. I am thankful if you would do that but…"

"I will never betray the person who saved my life."

"Alright, I will believe you."

"Un!"

Now that it has become like this, I have no choice but to believe that Rei will not tell anyone. Well, I somehow understood that she wasn't the type who breaks her promises after all.

Now that one problem has been solved, let's proceed to the next topic.

"However, the real problem will be after this. The transfer magic that will return us to the surface will be activated soon and yet, how should we explain about how we defeated the last boss…"

"Can Rin get out of the boss room by using your skill and return to the surface from there?"

I shook my head.

"No, it's not like that. When the last boss has been subdued, every adventurer who was inside the dungeon will be returned to the surface at the same time, whether they're inside or outside the boss room as the dungeon disappeared. That's why, even though I will definitely be able to hide the fact that I went inside the boss room, we will need to explain how Rei was able to subdue a powerful enemy that killed Kazami and the others…"

"Certainly it will be impossible to explain that… Then, how about this?"

Subsequently, Rei proposed a method to solve this problem.
