I Found Tiny Dungeon That Can Only Produce Metal Slime – Chapter 45

Chapter 45: Where’s Mana?

After that, he struggles to defeat the frogs under Tanaka’s guidance.

You slam the nickel into the frog as it jumps around. When the frog is spewing out a large amount of bodily fluids, you hit a switch, and then apply an electric current to it to finish it off.

Tanaka told him that the battery would soon run out if he left the switch on, so Yuma tried to apply the electric current to the frog the moment it was hit by the nickel.

Since I was using a long-handled ice axe, I was not exposed to the frog’s fluids as much as Tanaka who was fighting with a dagger, but I was still sticky all over by the time I got back home.

Tanaka-san… Is it like this every day?”

“Yeah, well. You’ll get used to it.”

He leaves the Blue Dungeon with Tanaka, who smiles brightly. The party broke up at Koganei Park, which was lit up by the setting sun, and Yuma went home at a leisurely pace.

For the next three days he dived into the dungeon and killed the frogs.

“That’s weird… I don’t know.

The morning of the fourth day. Maika frowns when Yuma arrives at work.

Is it still no good?

“Hmm… You’ve killed over twenty Blue Frogs, right?”

“Yeah, Tanaka-san and I worked pretty hard to take them down…”

“If that’s the case, it’s not right if their mana hasn’t gone up. One Blue Frog should raise your mana by about 0.2 to 0.3 per kill, so if you kill 20 of them your mana index should go up from 4 to 6. I think.”

The president of the company comes up behind Maika with a doubtful look on her face.

What’s wrong?

“Oh, sir. Something’s wrong. Yuma’s mana index is still at zero.

“What? It’s been three days. It’s probably gone up a little bit.”

No, not at all.

I think it’s broken. That meter must be pretty old.

Well, let’s try–

Maika pointed the tip of the measuring instrument at the president and pressed the switch. A beep sound is heard, and then she looks into the display window,


Yeah, I know.

Maika then walks over to Tanaka, who is working at his desk.

Let me take some measurements. Tanaka-san.

“What? Yeah, okay.

Point the gauge at Tanaka’s chest and press the switch. A beep sound is heard, and the index is displayed.


Yes, that’s correct.

In each case, the measuring instruments showed the correct values. The president scratches his head in annoyance.

It’s not broken.

Yuma felt uneasy when he saw the president and Maika talking about the measuring device.

“Um… Is it possible that it’s hard for me to raise my mana?

The president and Maika look at each other when they hear Yuma’s words.

“No, they say there’s a difference in how much mana you get… But it’s only a little.

“Yes! That’s not normal. I’m sure it’s fine.”

The president and Maika look puzzled. Yuma is worried that something bad might be happening to him because he keeps defeating the Metal Slime.

“Anyway, let’s just wait and see. If it doesn’t go up, we’ll figure it out then.”

The boss’s words have decided to maintain the status quo. Yuma and Tanaka head to the Blue Dungeon and hunt Blue Frog to raise their mana.

And two days later–


The president and Yuma are sitting opposite each other on the sofa at the back of the office, nodding their heads with serious expressions on their faces.

The president closed his eyes and crossed his arms.

“As expected, it’s strange that the mana hasn’t gone up after all this time.”

Is it just a matter of constitution?

The two of them were in a daze. The president seemed to be at a loss as to what to do in this unprecedented situation.

“Yeah. I’ve never heard of a constitution not raising mana, but I can’t say for sure. I’ll check it out.

“What do you mean, ‘find out’?”

“I know this guy who’s studying the effects of mana on the human body. I’ll see if I can get him to look into it.”

The president got up and made a call to somewhere with his cell phone that was on his desk.

Yuma got up and went back to his desk, scratching his head. This was unexpected.

I thought that if I defeated the stronger monsters in the dungeon, my Mana Index would steadily increase. But in reality, it doesn’t go up at all.

If I don’t get up there, I’ll never become a Seeker. I’ll lose my job.

There’s no dungeon-related company for Yuuma to work for if he gets kicked out of here.

When Yuma takes his seat with an uneasy feeling, Tanaka, who is sitting at the desk next to him, calls out to him.

“Are you okay? What happened?”

I’m supposed to find out why my mana’s not going up. I think he’s in contact with some scholar.

“Oh, that’s him.”

Tanaka lets out a chuckle in agreement.

You know about this?

“Yes, I know him well. She’s the scholar who does the search requests. A woman.”

“Oh, I see.”

He seems to be someone I know well. As I wonder what he looks like, Tanaka smiles wryly at me.

What is it?

No, Yuma. Just, just…

Tanaka beckoned to him and Yuma brought his face close to hers and listened.

That scholar is the boss’s ex-girlfriend.
