Dungeon Refrigerator 70

Test

There Is A Dungeon At The Bottom Of The Sea!?

Recap from the previous story. Three beautiful college students stepped on me, and I was panting when the sharp-tongued, otaku high school girl Shark intruded. I licked her feet as she entered.

"So, Shark. Is this about a dungeon?"

During the day, Shark seemed oddly interested in my strength. 

And in the current situation, dungeons were the only places where strength mattered.

"Uh, yeah..."

"Hmm... So, did you find a hidden dungeon that nobody knows about yet?"

"Huh!?"

When I asked that, Shark widened her eyes in surprise. Haha, as I thought. Quite an easy deduction, my dear Akechi.

"I see. So, you wanted to borrow my strength to investigate an undiscovered dungeon. Well, don't worry, I'll accompany you for that. Besides, I also train these girls to fight in dungeons. They'll keep such secrets for us."

"That's right... If someone were a well-behaved good kid, I could trust them with secrets too. (Glance)"

"Uh, ugh..."

Unlike during the day, Shark, dressed in a black top bra that looked like a swimsuit, topped with a khaki knitted net, was flustered by the flowery-eyed Nina-san in a yukata.

(Hehehe, what do you think, Shark? That's the charm of an adult woman, the art of enticement. It's a learning experience, my friend.)

But still, an undiscovered secret dungeon?

Hmm, it's similar to the Refrigerator Dungeon I have. 

I'm quite intrigued by this. If my Refrigerator Dungeon were to get lost somehow, having another secret dungeon might come in handy.

"So, where is this dungeon located? Since it's somewhere inconspicuous, is it in the mountains?"

"No... it's in the sea..."

"Whaat!?"

Everyone present gets taken aback by Shark's words.

"What the...!? I found it while diving and playing around the rocks, right? I saw this pitch-black thing swaying like an entrance to a dungeon deep in the rocky area. I think that's what it is..."

Oh, I was surprised. 

A dungeon underwater, who would have thought? 

It means people won't find it easily.

"So... If it's still an undiscovered secret dungeon, it's all mine, right? But I'm not strong enough to battle dungeon monsters, so I thought of asking Jung for help..."

"I see, so that's why it's me."

"But couldn't someone else, even another adult do this? You don't necessarily need a mentor, right?"

Serai-san still seemed to have an issue with Shark and expressed a negative opinion.

"No, if I told my parents or someone, they would object... Besides, among the people I know, Jung seemed to be the strongest and most reliable. Ah..."

Unnoticed, the 3 college girls were looking at Shark with grinning expressions, and she noticed, blushing and looking down.

"True... A strong and reliable man. There's no one better than Coach here, after all♪"

"Yes, Coach is incredibly strong. He can defeat goblins barehanded!"

"Hehehe... Your attitude might be bad, but I'll acknowledge that you realized how amazing your mentor is!"

(Sip. Ah, the tea is delicious. But why are Nina-san and the others acting so proud because of my strength...?)

"(Slap)! My level is 7, you know! And these two are level 6. Impressive, right?"

While pounding her right fist onto her left hand, Serai-san wears a yukata and tries to assert dominance over Shark, her junior. 

I wonder if she'd say something like "That'll be 530,000 yen.". 

But stop it. Seriously, how childish.

"You're a woman, but you're amazing! I want to be strong too! But I don't like bugs, and I'm not that strong..."

But what the heck, Shark is easily get swayed by it.

"That's okay...I didn't have any strength either, but after Coach taught me, I became three times stronger..."

(Oh? Have Ruu and Nina-san also started treating Shark as a senior?)

"All right! Let's go explore the secret dungeon now!"

"Yeah!!"

(Hey, wait! Once again, the capricious Serai-san made a sudden turn!)

.....

[(Sounds of rustling, clinking, rattling)]

"It's opened. Everyone, come inside."

"We're coming in~."

"Wow, it's so dark..."

((Sounds of rustling, clattering)] 

"If we turn on the lights, we'll stand out. Let's manage with flashlights."

"Hmm... Still, it's surprising. A dungeon right near the beach we visited during the day."

We drove to the sea and entered Shark's beach house, where she lives. Drunk driving? No, I only had a toast at the beginning. After that, I accompanied Ruu, so I didn't drink.

"Well, yeah. Since I found it while playing on the rocks during breaks from helping at my place."

"Oh, now that you mention it, that's right. Well, let's change quickly and head into the sea♪"

"Umm... I'll double-check, but is everyone okay with this?"

As I closed the sliding door behind me, I asked Ruu and the others again. Based on Shark's story, they wanted to investigate at night since it would attract less attention. But there was no need for Ruu and the others to accompany us to the dungeon, especially since they didn't have the proper equipment.

"It's fine! If Coach is going, then I'm going too! (Stick out tongue)."

"Come on. It's underwater. Plus, you'd be entering a dungeon in swimsuits, you know?"

"But even so, it's fine as long as I'm with Coach!"

Ruu seemed unusually eager, but I worried about her getting hurt.

"Well, if you overexert yourself like you usually do with Coach, your levels have gone up, so you can at least run away if things get dangerous, right?"

"That's right, master! They say you should let cute girls go on journeys!"

No, exploring dungeons isn't a journey. It's more like an adventure.

"Anyway, if it gets dangerous, we'll retreat immediately. We decided that earlier, right, Jung? Here, everyone, take one of these."

(Rattling)

Shark returned from the back with a long wooden stick placed on the table in the room.

"What's this?"

"A stick for watermelon splitting. It's pretty sturdy, and better than using our bare hands, right?"

"Oh, I see. Then I'll take it♪ (Grip, grip)."

"Hmm... Well, I guess there's no choice but to go now..."

"Yeah, that's right. Let's change on the other side of that partition. Coach, don't you dare peek!"

Ruu, Nina-san, and Serai-san disappeared behind the partition with their belongings.

"Yeah, I know. And I need to change too. (Thud)"

Yes, the Boston bag I brought from home. The bottom of it has a double layer. It only contains clothes for changing. But I'm pretending to take clothes out of the Boston bag while using my skill [Space] to retrieve my Bug King Suit from the dimension pocket.

First, I undress and put on the black bikini. When I wear the Bug King Suit, I fill it with slime to make it adhere to my skin. 

That's why I always wear a black bikini underneath, as the slime fills the interior suit and fits smoothly.

(Yeah... Start with the left arm as usual...)

(Shff... Plop... Squelch... Squelch...)

After fitting my arm through properly, I let the magic flow and made the suit adhere to my skin. Then, I fill the interior with slime from my skill to allow smooth movement.

(Squish... Gulp... Ahh...)

Suddenly, I felt a gaze and turned my head. Ruu was peeping at me from behind the partition. Startled, I tried to hide, but she had caught me. I wonder why she found it so mysterious.

(At times like this, instant transformation! Jupeen! If only I could transform in a snap...)

(Shff... Snap... Squelch... Squelch...)

Anyway, I put on each piece, making sure they fit snugly with magic and filling the interior with slime.

(Oops, I need to remove the gas mask filter set in the Insect King mask. If water gets in, it'll clog up. I won't be able to breathe.)

(Scuffle... Gulp... Ahh... Gurgle... Gurgle... Sploosh!)

*(Transformation! Acidman! Jupeekin! It takes about three minutes to transform.)

"Hmm...? Oh my! What the...? You had that outfit all along? Ugh... that scared the life out of me..."

Seeing me in the dim light, Nina-san screamed in a voice that resembled a scream.

"Huh? Oh, you're right, master, it's not good to wear that at night. If the police see you, they'll shoot without hesitation!"

"Hey, have you changed already? Gyaahh!!"

"Hey! Wait...! Shark, it's me, Jung! Don't throw the knife!"

"Look... I didn't mean to..."

"Wha...? Jung!? Seriously! Don't mess with me! I thought you were a monster or something!!"

"No! This is the full outfit I wear when I dive into dungeons!"

"Haa...! Haa...! I thought my heart was going to leap out of my mouth..."

"...I'm sorry. But, you've got quite an outfit on, too."

Shark had disappeared for a while and returned in a pitch-black diver's outfit, complete with an oxygen tank on her back.

"Oh, because we're diving into the night sea. You can't do it without a tank, right?"

Truly a nerd. Well, I don't need to explain anything to her; she won't make any clumsy moves in the dungeon.

"Good choice. But if someone starts drowning, I'm counting on you to help."

"But before that... thanks to Jung, I felt like my heart was going to stop... (Glaring)"

"Uh, sorry..."

And so, after preparing ourselves, we stealthily headed into the night sea while being cautious of prying eyes.
