World's Fastest Level up!

After excitedly talking about Wolven, I told Claire that I wanted Yoizuki to explain about joining the guild to my sister too. Naturally, Claire, who knows about her to some extent after the fight against Yanagi, was immediately convinced, and promised to tell the Guild Master about it.

After we had parted, I brought my feet to Onizuka Dungeon instead of returning home. Because the investigation on this dungeon is still insufficient, ordinary adventurers are not allowed to enter. However, I don’t know a place with a level-up efficiency higher than this place. Hence, I decided to conquer this dungeon before more people gather at this dungeon. Needless to say, not in a normal way.

“Transfer within dungeon!”

And I arrived at the 30th floor a moment after I entered the dungeon. Claire had said that a large number of monsters would appear if I stayed on this floor for more than 10 minutes, so I went directly to the boss room where the High Ogre was instead of waiting for that time to come.

When I entered through the opened door, just like before, the door automatically closed. Then, from behind the wall, a High Ogre with reddish-black skin appeared.

“GAAAAAAAAAAA!”

“Looks like it properly appeared even in my second challenge. Thank you for that.”1

Holding the Nameless, I faced the High Ogre head-on. Unlike yesterday, there is no magic stored in Greed. Thus, I had to fight against this powerful enemy using Nameless only.

However, I wasn’t worried about it, as my level has increased by 2,000 upon capturing it yesterday. Along with that, my status was greatly strengthened, and I also acquired some skills. Thus, even if no magic is stored, I still will not lose.

“…. Here I go.”

Then, the second battle between the High Ogre and me began.

＊

Dozens, or even hundreds of swords flashes blinked in the sky, and the overlapping slashes became big waves that tore through the hard skin of the High Ogre one after another.

“GAUUU!?”

“Too slow”

Although the High Ogre desperately tried to resist, by freely using Time Zero, I could easily evade its attacks. Although I still can’t let my guard down as those attacks have considerable power, there is no problem as long as I face it calmly, as my Time Zero is extremely effective against these kinds of huge monsters.

Unlike the Salamander or Griffon, whose bodies are covered with magic, the High Ogre who is good at physical offense and defense cannot use magic to begin with. Even its only ability, which is Hardening, didn’t work against my Time Zero.

As a result, approximately 1 minute since the battle began, albeit longer than the last time where I could release magic using Greed, I was able to deal more stable damage more than previously. And with the chance generated from that way, I powerfully swung the Nameless, making the silver blade cut through the High Ogre’s chest and destroying its magic stone at the same time.

『Experience acquired – Level has increased by 1213』

『Dungeon capture reward – Level has increased by 100』

『Extra boss subjugation reward – Level has increased by 200』

The reverberating sound of the system was the proof that I had won against the High Ogre, announcing I gained enormous experience points.

Then, I checked my status and saw an intense MP consumption because of using [Superhuman Strength], [Gale], and Time Zero constantly at the same time. However, it seems there was still quite some left.

“This is just the start.”

After returning to the surface by transfer magic, once again, I entered the dungeon. And from that moment, a level-up that exceeded the speed of God has begun.

It’s an extra boss, so it might be one time only.
