World's Fastest Level up!

After having a good night's sleep, I lightly moved my body to inspect my condition.

"Un, not bad. My HP and MP also have almost completely recovered, so I think I can already go to the next floor."

Therefore, I decided to advance to the second floor right away. But, here, I discovered a problem.

"How do I even go to the second floor? There are still no stairs leading up…"

Right when I think about that, the sound of the system reverberated in my mind as if waiting for this timing.

『Challenge the next floor or retire. Please declare one of them if the subject has made his choice.』

Fumu. Looks like it will respond if I put it into words. Hence, I promptly declared.

"Challenge the second floor."

『The subject’s intention has been confirmed. Transference will be conducted.』

As usual, a pale white light enveloped my body. The transfer magic was activated and when I realized, I was already standing in another place.

"The heck is this place…."

The second floor was the exact opposite of the first floor’s vast grassland where I couldn’t see the edge.

Currently, I was standing in an approximately 200 meters square fully tiled area. And I couldn’t help but be surprised at the change.

"As expected this dungeon was different from normal dungeons. The change on the terrain was the same as before, something that doesn't seem to look like inside a tower…. Perhaps each floor really is in a different place"

Spontaneously, I ended up thinking about such a crazy idea in my mind–Oops, I have no leeway to keep thinking about this forever.

"What will the quest of the second floor be? I can't seem to find any monsters as far as I can see…."

The one who answered my question was of course, as usual, the sound of the system.

『The quest for the second floor is 【Mirror Knight】. Please subjugate one targeted knight.』

The sound of the system ended there.

Quest name [Mirror Knight]. The subjugation target was only one.

Although it sounded easier than the quest for the first floor, conversely, the strength of the enemy might be skyrocketed.

"It came, huh."

Then, a knight whose body wrapped in silver armor appeared as if it arrived with transfer magic. Albeit some parts were different, the knight was quite similar to the Nameless Knight.

As always, I used the [Appraisal] towards the knight.

"This is….!"

And what's written in the description made me open my eyes.

______–

【Mirror Knight】

・Recommended level to subjugate: 6604

・A knight created mirroring Amane Rin's status.

・Failed to replicate some skills.

______–

【Mirror Sword】

・A sword created mirroring the Nameless Knight Sword.

・Recommended level to use: 6000

・Attack Power +6000

・+56% to all statuses except HP and MP if the enemy's level (Recommended level to subjugate) is higher than the user.

______–

"It’s a copy of my status and the Nameless Sword?! So it was like that, it's because the system inputted my status at that time…!"

When I’ve just conquered my 10th dungeon, the sound of the system certainly has announced such things.

"Nevertheless, I never thought it would be used like this."

Even so, I have no choice but to do this.

I held the Nameless Sword and faced the Mirror Knight.

"Now, you can come at me from anywhere_-!"

I couldn’t properly finish those words. Because before I knew it, the Mirror Knight already  reached before my eyes much faster than I expected!

"Damn!"

After avoiding the blade swung by the Mirror Knight by a hairbreadth, I immediately put some distance between us.

Once again, I focused my gaze to the enemy and smiled bitterly while wiping the sweat on my forehead.

"I see, of course it moves unexpectedly…. It also has that sword after all."

I turned my sight on the Mirror Sword–the sword that copied the ability of the Nameless Sword. In other words, the exceptional rises in statuses when fighting a higher level enemy.

The level of the Mirror Knight was 6604 while my level was 6900.

_Unfortunately, the condition has met.

"Although I have considered this possibility when I saw it have the Nameless Sword, nonetheless the effect can be manifested even if possessed by a monster, huh. Really, what a difficult opponent."

The superior enemy-hunting that I was good at until now. By having an opponent that utilizes the same advantage, I once again understand the cheat-ness of the Nameless Sword.

"Does this mean the recommended level to subjugate became 10000 if the increase of the statuses were added? The difference is about 3000 levels. What an overwhelming disadvantage for me–"

Knowing that fact, I fearlessly laughed.

"–But that's why it's worth the challenge. I'll have you become my stepping stone, Mirror Knight!"

And then, the death battle has begun.
