The Hidden Dungeon Only I Can Enter

The Hidden Dungeon Only I Can Enter, Secretly Becoming World Strongest!」

Gogogogogo…

By saying the password, the entrance of the dungeon opens with a sound.

No matter how many times you say this password, it does not cease being embarrassing.

By the way, it’s has been a long time since I’ve been here.

I wonder if my master felt lonely all this time?

As I was a little hungry, I started thinking about hunting slimes on the first floor and eating their golden jelly.

Thinking that way, my spine stiffened when I carelessly turned the corner.

「..isn’t it too big?」

At this moment, in front of me, there is a Golden Slime.

No, wait.

Is this really a slime?

It’s too big for it to be one.

It’s so big that it can touch both, horizontally and vertically, the ceiling and the walls. Of course, much more than me!

I wonder if this monster is the Boss Golden Slime?

If so, it should spit liquid while making a cute『kyapuchiyua』 soundー

「Kyabujuuaaaa!」

「It’s not cute at all!」

While screaming, I run with all my strength.

The amount of fluid that spits is no joke at all.

*bichaaaa*, a sludge-colored liquid is spat on the floor. Luckily I was able to escape without suffering from its spit.

For now, let’s take a distance.

*Zuri, zuri, zuri, zuri*

The huge body of the enemy is approaching. The feeling of oppression it gives is amazing.

Let’s examine it for the time being.

Name: Golden Slime

Level: 138

Skill:

Corrosive liquid Union Separation

What a high level!

That said, the name still says Golden Slime. Could it be a mutant variation?

Wrong.

I think the skill 【Union】 is the key here.

Although it doesn’t matter right now, let’s fight first.

If it’s dangerous I can turn back, or I can use the transfer skill to go to the second floor.

Taking a safe distance, I shoot a stone bullet.

「Gyabujuaaa!」

It had no effect, but it made it very angry…

Its body has great elasticity, so it seems impossible to hurt it with a rock.

「How about this?」

I shoot a stone bullet with the imbued power of the white flame. Slimes tend to have a weakness against fire, so it should be more effective than before.

Bichaaーー

A rippling sound echoes in the passage as the fire stone bullet splendidly passes through it.

The rippling sound is because the monster separated its body despite having a huge body capable of covering the entire corridor.

The giant body separated into five monsters.

Now, there are five slime of the normal size in the passage. After appraising them, their levels are 24, 22, 28, 23 and 41.

If you sum them up… it gives the 138 level giant monster.

Now now, this last one monster has the skills 【Union】 and 【Separation】.

The level 41 monster has to be the leader and the one who created that enormous monster.

But even if you combine those five, it would be impossible to form that enormous monster. Is this the power of the skills?

I don’t have time to think about that right now.

Each of the five bodies are attacking separately.

「Should I give up the golden jelly…?」

Although it’s only a slime, I’m a little afraid to face the five together. Though in the end, I was able to kill them all with the fire stone bullets.

In this dungeon the more time passes, the more demons appear. I wonder if monsters like this suddenly appear?

I heard there are many places like this in common dungeons too.

Excited by this unusual situation, with my heart beating, I went to where my teacher is.

「It’s has been a long time, master」

『……』

「Master?」

As always, my master was hanging from chains.

I have told my teacher this many times. That I would find the way to remove those chains.

But every time, my master told me that it was not necessary. I wonder if it’s because they are comfortable?

「Are you sleeping?」

I felt a noisy feeling around my heart.

「It has to be a lie… Master… For you to dieー」

While I say that, I try to poke master’s belly with my fingers.

『Nyahahahahaha!』

「ーーLike I thought, you were pretending」

『Kuuuu… It’s really frustratiiiing…』

Disappointed that she was found out that it was an act, she let out a strange *Kii kii* voice.

「You really like doing mischief, isn’t that right?」

『But it’s only because Noir does not come to visit me at all! I got to the point of wondering if you had deleted Olivia from your memory~』

「I’m sorry, many things happened」

『Like what?』

「It will be long, but are you interested?」

『Yes, yes, I a~m! I’m interested in knowing things like Noir’s first kiss!』

「Rejected!」

『Stingy』

「Errr… Where should I start?」

I told her how I dispelled Maria’s curse.

And how I got 100 million ria in reward.

『Amazing, right? As expected from Olivia’s disciple』

「Everything is thanks to having received master’s power」

『It’s not quite right, I believe that it’s Noir’s power. Since I’m not the type to spend my LPs to help people』

There are many ways to replenish LP, but if there weren’t any, I might also think like that,

『Ye~ah, now that you have money, it may be time for that』

「Are you going to recommend me a skill?」

『It’s nothing to that extent… Although the efficiency is bad, what do you think about an ability to earn LP with money?』

「If there was something like that why tell me now?」

『Because you know… you were poor until moments ago』

You are quite right.

It means that she cares about me.

While being taught by my master, I tried creating that skill at once.

【Money → LP Conversion】 500 ＬＰ

Since I was saving up steadily, right now I have more than 1500 LP. I have no problem in obtaining it, the problem is the effect.

＜It’s possible to convert 100.000 ria = 1 LP＞

It’s so expensive…

10 LP = 1 million ria

100 LP = 10 million ria

1000 LP＝100 million ria

By the way, when I tried to change the conversion amount, I was asked for an exorbitant number of LP.

「Uuーーーーuuh…」

『See? It’s hard to be poor, isn’t it?』

「It’s tough even if I’m not poor, you know? But even so…」

『Right, this is something like insurance. It’s a skill that can be used if you become a millionaire』

Following her advice, I created that conversion skill.

More or less, I have 100 million in my inventory.

I gave half to my family, but in the end, as it was scary, I kept everything with me.

I will start with 100.000 ria at the moment to practice.

It seems that you must have the money in front of you or touch it, and think about it.

I hold the money tightly. I declare my intentions on my mind. Conversion.

Uwa, it’s really gone!

1025 ＬＰ → 1026 ＬＰ

Yeah, it works, no doubt.

「Where do the missing coins go?」

『I wonder where~』

「They surely go with a *clang* to the house of unfortunate children」

『Noir-kun is such a romantic~ But I like that』

「It’s better to be positive」

It’s fun to talk to master, but I think it’s time to continue capturing the dungeon.

ーーRight, that reminds me, I haven’t talked about the Black Lion on the fifth floor yet.

I wonder if my master which has abundant knowledge about monsters will know about it?

『ーI have never seen such monster, but I heard about it when I was an adventurer. There were such monsters 100 or 200 years ago』

My master is an adventurer from two hundred years ago or so, so it should be a monster of about 300 or 400 years ago.

It seems that she has no other information besides that so I went straight to the fifth floor with my skill.

I go right to the staircase on the fourth floor that connects with the fifth floor.

Suddenly, I was speechless.

『I’ve been waiting for you, human』

In front of me, was the Black Lion that I just talked about!

As usual, a tulip is blooming from its head.

I move my eyes slowly toward the stairs. I wonder if I will be able to escape if the enemy jumps towards me…?

『Can’t you hear my words? Human』

「I… I can hear, them」

『I was waiting for you to come back』

As expected, this Black Lion is skillful with the words.

I was a little surprised since the monster is able to reason, but I can’t lower my guard yet.

「Umー. You said you have been waiting for me, don’t tell me that it was since that time?」

『That’s right』

「It has been a long time, don’t tell me that you have been always in the same place?」

『Not all the time. Once every three days, there is a 15-minute break to eat and excrete.』

「Then, other than that」

『I’ve been waiting all this time for you here』

The Lion said it with a face like it was a natural thing to do.

I’m terribly scared!!

A Tulip Lion appears!
