I Found Tiny Dungeon That Can Only Produce Metal Slime - CH 12

Chapter 12: Blue Dungeon

After arriving in his room again, Yuuma threw away the bag containing the measuring tool at the edge of the room.

He sat on the chair of his study desk and hung his head low.

「DAMMIT ALL! I SPENT 19800 YEN FOR NOTHING!」

Though Yuuma was really pissed off right now, he had no idea how to vent his anger.

Though the shopkeeper of the electronic store had told him that his mana index wouldn’t rise no matter how many slimes he defeated, the monster that he defeated wasn’t your average slime. It was the rare, metal slime.

「LIKE HELL MY MANA INDEX IS ZERO AFTER I BEAT BUNCH LOADS OF THEM!」

But, he couldn’t use the 『Magic Ore』 unless he know his mana index. Yuuma then tried again to search how to measure the mana index with 0.1 accuracy.

「U~hm, a precise measuring instrument can go up to 100k yen huh? Even the second-hand one is 70k yen… truly out of my reach.」

If he swallowed the 『Magic Ore』 without knowing his mana index, there was a chance that it wouldn’t disintegrate and come out with fe*es. Yuuma took an even closer look at the magic ore in his hand.

「It’s really big. My a*ss definitely going to be screwed if this magic ore isn’t disintegrated in my body…」

Yuuma shuddered upon imagining that kind of situation. The reason being no one wanted the iron ball with a diameter of around two centimetres coming out from their a*ssh*ole. Yuuma continued to look for another way to measure his mana index.

Thereupon, he stumbled upon a certain article.

「There’s a measuring instrument in the dungeon?」

He read that particular page on the homepage of dungeon management in Tokyo.

『Blue Dungeon』 which is located in Musashino city was a popular spot whose shallow layer was safe enough even for children. It said on the homepage that everyone could measure their mana index for free as long as they paid the entrance fee.

「THEY’VE SOMETHING LIKE THAT!? AND MANA MEASURING TOOL WITH HIGH PRECISION ON TOP OF THAT… THIS IS IT!」

Though Yuuma’s family house is located in Tokyo, it is on the outskirts which is far away from the centre. He would arrive in Musashino city in ten minutes by train.

Yuuma leapt out of his room again, taking only his wallet with him.

◇◇◇

Yuuma who came out from the train in Musashino ward station then left looking around restlessly after he left the station.

「Over there huh?」

After walking while following the GPS of his smartphone for a while, he finally saw a white, dome-shaped building. Yuuma quickened his pace.

That was the facility built around a small park, it was 3000 square meters in size.

Though the building felt like the downsized version of Tokyo dome, it was covered by a bulky wall on four sides to prevent any intruders.

Yuuma registered at the front desk and went through the automatic door.

Since today was Sunday, the facility was more crowded than on weekdays. Yuuma called out to the female receptionist.

「Excuse me. I want to enter the dungeon.」

「Is this the first time you’re visiting this place?」

A beauty in her twenties asked so with a gentle smile on her face.

「Yes, this is my first time. I hear that I’ve to pay, right?」

「Yes, there’s an entry fee. A normal citizen can enter up to the third floor, which floor you’re going to enter?」

It seems there’s a different fee depending on the floor. Well, the 1st floor should be enough for now.

「First floor, please.」

「Okay. The entry fee for the first floor is 1000 yen. Ah, we also provided a student discount if you are one, do you bring your student id?」

Yuuma rummaged through his wallet and took out his student id card, thus he only needed to pay 800 yen after the discount.

「This is the entry proof. Please go ahead, the entrance of the dungeon is right at the end of the passage.」

「Uhm, I want to measure my mana index too…」

「Mana measurement room is on the right. You’ll know once you enter the passage.」

「Ah, thanks.」

A while after he went into the passage, he saw a billboard with bold 『Mana Index Measurement Room』 written on there. Though some people were lining up to use it, the number wasn’t that much.

Yuuma received his number and decided to wait in the sofa provided along the corridor.

After waiting nervously for around ten minutes.

「Number 286, Please enter the room.」

「Y-Yes!」

Yuuma walked into the mana measurement room with his entry number in one hand.
