From Sneaker Bunko, a special PV for this work has been released.

Please take a look if you have a moment.

In the 15th floor of the D-Rank Dungeon [Yūnagi Dungeon], more than ten goblin corpses were scattered, and only three remained.

I was facing those three alone.

"Ha!"

*Slash!*

The tip of my dagger sliced through the goblin's throat. Ignoring the one that fell, spraying blood, I attacked the remaining two.

"Roar!"

"Ugh!"

"Too slow!"

The two goblins attacked in coordination, but it didn't work on me. After all, I've been an adventurer for a year. I've seen this kind of attack more times than I can count!

"This is the end!"

After dodging their attacks, I finished off the two of them.

Then, a familiar system sound echoed in my head.

*Level up! Experience gained. Level increased by 1.*

"Ah, there it is. Let's check the status."

It's been five days since my last level up. I immediately opened the status screen.

----------------------------------------

Amami Rin, 19 years old, Male, Level: 95

SP: 0

HP: 785/820 MP: 120/130

Attack: 200

Defense: 160

Speed: 180

Intelligence: 110

Skills: Dungeon Teleportation LV9, Body Enhancement LV3, Basic Magic LV3

----------------------------------------

Dungeon Teleportation LV9

Condition: Can only teleport within the dungeon where the user is located

Teleport Distance: Up to 20 meters

Activation Time: 3 seconds × Distance (M)

Target Range: The user and what the user is wearing

----------------------------------------

Yeah, my level has indeed increased from 94 to 95. The stats have only increased slightly, so I don't feel a big difference.

Still, looking at my stats always makes me feel a bit depressed. It's clear how incompetent I am.

"Normally, in a game, level 95 would be pretty high. But in reality, I'm at the bottom... or maybe in the lower middle? I heard the top-ranked adventurers in the world are over level 100,000. Sigh, I don't think I can catch up at all."

Well, the dungeons first appeared 20 years ago. The top-ranked adventurers have been active since then. It might be too ambitious for me, an adventurer with only one year of experience, to try to catch up.

"Wait, didn't the Yūnagi Dungeon give a 5-level bonus for clearing it?"

When you clear a dungeon, you get a level-up bonus in addition to the rewards. For an E-Rank Dungeon, it's 1 level, and for an A-Rank Dungeon, it's 100 levels. The Yūnagi Dungeon gives a 5-level bonus.

Some might think that clearing the dungeon multiple times is more efficient for leveling up than grinding monsters inside. However, there's a big problem with that.

Once you clear a dungeon, you have to wait a week before you can challenge it again. The reason is unknown, but the information about clearing a dungeon is shared worldwide, so you can't challenge other dungeons either. For adventurers like me who earn a living inside dungeons, clearing them isn't very profitable.

"But this is an exception. If I clear it, I'll instantly reach level 100..."

You get SP to enhance your skills every 10 levels. At level 100, you get 100 SP, which is exactly what I need to upgrade my Unique Skill, Dungeon Teleportation, from level 9 to level 10. Many skills become much stronger when they reach level 10, so I want to test it out right away.

"Alright, my earnings will decrease for the next week since I can't clear the dungeon, but I have no choice. Let's go!"

I made up my mind and headed to the deepest level of the Yūnagi Dungeon, the 20th floor.

The boss of the Yūnagi Dungeon, the Dual-Tailed Beast, is a monster that uses its two tails skillfully to attack. It's a difficult enemy to handle until you get used to it. However, this is my third time facing it. I fought calmly and managed to defeat it successfully.

The rewards for clearing the Yūnagi Dungeon are worthless magic stones that can only be sold for a pittance, and the 5-level bonus I mentioned earlier.

As expected, the system sound echoed in my head right after I defeated it. You don't need to do a victory pose or anything; the rewards are given automatically. Good job!

*Level up! Dungeon clear reward. Level increased by 5.*

----------------------------------------

"Phew."

I took a deep breath. This moment might change my life as an adventurer.

"Looking back, a lot has happened in the past year."

Right after graduating high school, I got my adventurer's license and challenged the dungeon. I successfully obtained my stats by being exposed to the special magic inside the dungeon and acquired the Unique Skill, Dungeon Teleportation.

At first, many people were amazed and had high hopes for the extraordinary power of being able to teleport freely within the dungeon. However, as I used it, various flaws were revealed, and it was deemed useless and called an incompetent skill.

I was frustrated. I wanted to prove them wrong. I wanted to show that this skill's power wasn't just this much.

So, even as my peers grew rapidly, I continued to work as an adventurer, crawling on the ground if I had to.

Now, it's time to see if my efforts will pay off!

"Alright, let's do this."

I decided to allocate all my SP to Dungeon Teleportation. Would the teleportation distance increase? Or the activation time decrease? Or the target range expand? Or...

*The skill level of Dungeon Teleportation has increased to 10.*

*The conditions have changed.*

*Can only teleport within the dungeon where the user is located → Can only teleport within the dungeon the user has stepped into.*

The system sound seemed to end there.

"Can only teleport within the dungeon the user has stepped into...?"

It took a while to understand the meaning of those words. Then I realized that this wasn't the result I had hoped for.

"Of course... it wouldn't be that easy."

I had many fantasies: if the teleportation distance covered the entire dungeon, if the activation time was 0 seconds, if the target range included other adventurers. But it wasn't that simple.

Even so, I'm a bit confused. Being able to teleport to any dungeon I've stepped into... the dungeons are at least a few kilometers apart. No matter how much the teleportation distance increases from 20 meters, there won't be many opportunities to use it. It's a completely meaningless evolution.

"Ah."

I let out a deep sigh of disappointment. My year-long expectation has been betrayed. Please understand.

As I was feeling down, my body was enveloped in a faint light. It was a signal that the teleportation magic to return to the surface was activating.

"Ah, dangerous, dangerous."

I quickly collected the magic stones from the dungeon's rewards and the Dual-Tailed Beast. Then I waited for the teleportation magic to activate.

I was so depressed that I wanted to cry for three days and three nights. But I can't stay like this forever.

"The next chance for a major skill evolution is at level 20. I don't know how many years it will take, but I have to start over and keep trying."

I slapped my cheeks to regain my spirit. At the same time, the teleportation magic activated, and I returned to the surface.

At that moment, I had no idea of the true value of the Unique Skill, Dungeon Teleportation. I didn't know that the power gained from this level-up would have an incredible effect.

--- I would realize that one hour later.
