World's Fastest Level up!

One hour later, when signs of fatigue began to appear on Hana's face, we decided to end the dungeon exploring and monster subjugation for the day. However, considering the leveling-up efficiency, it would be a waste to return just like this.

Hana is a high schooler, so she could only come to the dungeons once or twice a week. This means, the influence of the intermission after capturing a dungeon is relatively small on her. Hence, I thought why don’t we go home after capturing this dungeon since we are already here.

However, [Transfer Within Dungeon] could only be used by me, and it takes almost half a day to capture this dungeon normally, which is also quite difficult on Hana's stamina.

Therefore, after thinking about it for a while, the action that I took was–

"Yosh, let's go!"

"Eeh!?"

–I princess-carried Hana and rushed to the bottom floor with all my might.

And approximately 30 minutes later, I defeated the dungeon boss in a single blow, increasing Hana’s level by 12.

"… Onii-chan?"

"Yes"

However, in return, Hana was staring at me with a pout outside the dungeon after the capture. Still, her angry face is also cute.

"Although I nodded when you said, ‘Since we're already here, shall we capture the dungeon too? There is actually a good way to do that, can I try it?', I never imagined I would be carried all of a sudden and be able to move at a high speed, you know! It was quite fun, though!"

So, it was fun after all. I'm glad.

Although she did complain to me energetically, she didn't seem to be really angry. Then, she took a deep breath and extended her hand saying, "Nn"

"Well, I'll forgive you since you did it for me. Now, let's quickly go home, Onii-chan"

"Aa"

Thus, I held Hana's hand, and we headed home together.

After having lunch at a family restaurant and sending Hana home, I went out once again.

The time is around noon. I thought it was still a little too early to rest, so I went to the dungeon again.

There were many adventurers around, wearing excellent equipment on their body. Veteran warriors. Their figure was fit to be called that way.

But that was as expected. Because this place is a B-rank dungeon with a recommended level of 10,000–[Suzuka Dungeon] after all.

In this world, due to the influence of the dungeon capture reward, the higher one's level is, the more efficient their level-up will be. But…

Even with that, it will take five to six years even for an excellent adventurer to reach level 10,000. In other words, the adventurers around here were those people who had been adventurers for a long time. It goes without saying, their aura was clearly different from those of C-rank or lower.

"I've finally come this far, huh. Yosh"

Bracing myself, I faced the Suzuka Dungeon, my first B-rank dungeon once again.

With [Transfer Within Dungeon] turning Lv 21, I could even enter a dungeon that I have never challenged before. This means, the influence of the intermission has completely disappeared for me. And then–

"Transfer Within Dungeon!"

—Like that, I challenged a B-rank dungeon for the first time.
