World's Fastest Level up!

After capturing the ninth floor, I rested by taking a short nap before making some adjustments in preparation for the tenth floor. Although I said adjustments, the only thing I did was just allocating my SP, though.

I had already raised the level of [Superhuman Strength] from Lv 7 to Lv 8, and [Gale] from Lv 7 to Lv 9 before clearing the ninth floor but right now, I still had 12,510 SP remaining from the leftovers of that time combined with the increase in the ninth floor.

Now the question was which skill should I raise the level using this SP. Then suddenly, my eyes halted in one of the skills in the skill's list.

_____–

Transfer Within Dungeon Lv 18→Lv 19 (Required SP: 4500)

_____–

"Transfer Within Dungeon, huh…"

According to the tendency so far, the required SP to raise the level of this skill from Lv 19 to Lv 20 should be 5,000 SP. Combined with the SP required to raise its level to 19, a total of 9,500 SP would be used to level this skill to Lv 20, which could be done immediately.

However, I shook my head.

"No, just because I raised it to Lv 20 does not mean the skill will evolve to be a skill that could be used in battle. Thus, let's save that kind of fun after the capture. Therefore, I'll raise these skills for the time being."

[Superhuman Strength] to Lv 9 and [Gale] to Lv 10. And with the remaining 3010 SP, I raised [Magic Power Increase] from Lv 5 to Lv 7.

With this, preparation completes.

"Now, it's time for the last floor. Let’s brace myself."

After that, I told the sound of the system of my intention to challenge the tenth floor, and soon, the transfer magic was activated.

When I opened my eyes, it was an endless wasteland that stretched out in front of me.

The skies were covered with clouds and the tingling sensation of dense magic power was piercing my skin. It was an area that even made me feel like catching a glimpse of the inside of hell.

And in the center of the area, a beast was enshrined.

The beast that stood there with the four limbs that looked as if wearing a black armor, boasted a height comparable to that of the Orc General and nearly doubled the body length. The bulging muscles and bones, as if strangled by a large rope, also ferociously asserted their existence.

A huge tail that could level the ground with a single sweep, fangs and claws that could pierce and tear through steel. And above all, despite being a monster, with a pair of strong-willed sharp yellow eyes, the beast was looking at me.

"GRUAAAAAAAAAAAAA"

Once the beast roared, multiple lightning strikes descended from the sky, burning the earth. That scene was very unrealistic.

And then, as I stared at that scene, the sound of the system reverberated in my head.

『The quest for the tenth floor is 【King of Thunder】. Please subjugate the Tenraijū.』

Hearing that, I used [Appraisal] toward the beast.

______

【Tenraijū】1

・Recommended level to subjugate: 20000

______

It was very simple yet hopeless information.

"Haa, I see. The last quest has no tricks or shortcuts, just a fully head-to-head fight, huh. Good, I'll do it."

I readied the Nameless Sword and looked at the thunder beast and brazenly stated.

"Let's do this, Nameless–This is our last battle."

In this way, the last battle in the Isolated Demon Tower where I bet everything has begun.
