Chapter 68: Email From IDR

「That’s… that should be the error range of the measurement right?」

「What are you talking about? It’s a fact that your physical strength has been enhanced!」

Aisha spoke while closing the black file with a snap.

With such insignificant increase after eating 421 magic ore… Meaning that muscle training was more effective in this situation.

「Okay, let me fix your misunderstanding, Yuuma-kun. This physical enhancement is another type of magic. In short, you can’t use it outside of the dungeon. Even the current data is unrelated with actual data when you’re inside the dungeon. The fact that we can do these simple examination can be considered as wonderful.」

「Ha~h…」

Yuuma didn’t feel delighted even the slightest after being praised like that.

「We’re going to enter the dungeon again starting tomorrow. This time, we will aim for the 50th floor!」

「50TH FLOOR!?」

Yuuma’s eyes opened wide in shock. The 50th floor was considered to be a fairly deep floor.

「Oi, that’s almost impossible feat with just Yuuma and me alone you know.」

「And it’ll be your job to achieve that! I’m expecting you to do this, Kotaro.」

Aisha left the room after she said so. Yuuma and the president heaved a deep sigh at once.

「President, are we really going to dive into the 50th floor?」

「Well, it’s the demand from the one who gives the commission after all. Legally speaking, we can’t refuse her demand. That’s why we have no choice but to do as she says.」

The president stood up from his chair and then looked down at Yuuma who was still sitting in his chair.

「Yuuma. I’ll give you CQC training starting from tomorrow to raise your physical strength too.」[ED/N: CQC stands for Close Quarter Combat]

「Eh, CQC training? Can you do that, President?」

「Of course! I’ve been training in various martial arts since a tender age. Karate, muay thai, boxing, kung fu, judo, even wrestling.」

「Awesome.」

「You want to become stronger too right?」

「Yes. Please train me!」

Then the CQC training from the president started the next day. They changed into jerseys the moment they woke up and did a light stretching.

「First, let’s start with karate-style’s straight punch.」

「Yes!」

「Open your leg until it is as wide as your shoulder and place your arms perpendicular on your flank. Let your shoulders to lose, close your armpit tightly.」

「Yes!」

Yuuma followed the president’s instruction to take a stance, he took a breath and loosened his shoulder. The president also took the same stance, and gave an example of a straight punch to Yuuma.

「1, 2, 3, 4, 5!」

The president punched forward with both fists as he started to count. It was an example of a good punching form.

「Do the same as me.」

「Understood.」

Yuuma mimicked the president, he used his waist as a fulcrum and then punched forward.

「Put more power into your waist! You have to put more focus on your waist rotation and the shifting weight on your leg!!」

「Yes!」

Yuuma, who had never experienced CQC training before, punched forward in high spirit since he knew that this training would boost his overall strength as an Explorer.

「Listen, Yuuma! I can’t carry both you and Aisha all the way until the 50th floor by myself. We need to cooperate. For that reason, I need you to be able to at least fight as the vanguard along with me.」

「Yes, I’ll do my best!」

「Anyhow, your first training menu is straight punch till you get the perfect form! Make sure your power transmitted properly from your leg to waist, from waist to arm!!」

「Yes!」

Black Dungeon, 30th Floor――

「UWOOOOOOOOOOOOOOOOOOOO!」

「UWAAAAAAAAAAAAAAAAAAAAAAAAAA!」

The president and Yuuma, both of them were running away from the rock monster that was rolling on the hill.

The outer appearance of that huge rock monster was akin to a ball. They would surely get crushed to death if they got run over by the monster.

「Ah, Yuuma! Use your 『Metallization』 and try to punch that monster!」

「Right now!? That’s going to ki–」

「You’re invulnerable to physical attack in your metallization state right? Try it first, you’ll be fine even if you fail!」

「Ah, you’re right! Okay!」

Yuuma then invoked his metallization that turned the color of his skin to metallic black. He stopped and stood in front of the rolling rock monster, trying to stop it.

「Come at me dammit!!」

Yuuma set his stance, clenched his fist, ready to unleash 『Straight Fist』.

The rolling rock then bounced up. Yuuma glared at the incoming rock monster, and unleashed a straight punch.

The sound of their colission reverbrate inside the cave. Yuuma felt a reaction but, at that point, he was already thrown back into the air.

「NAAAAAAAAAAAAAAAAH!?」

Yuuma got sent flying by the rock, tumbling on the ground, crashed against the wall behind him, and then fell like a puppet with its string cut, completely stopped moving, not even a twitch.

「YUUMAAAAAAAAAAAAAAAAAAAAAA!! Are you okay!?」

The president rushed at him, grabbed his shoulders and shook him a few times. At that moment, Yuuma’s eyes snapped open.

「HAH!? What a surprise. I thought I really died a while ago!」

Yuuma stood up again as if nothing happened.

「A-Are you alright? I mean, I almost thought that you got isekaied by that colission just now!」

「A~h, well, I’m perfectly fine. I mean, it doesn’t even cause any physical damage to me.」

Even the president ended up getting himself dumbfounded by the toughness of Yuuma’s body. Aisha, who came a bit later than the president, came and checked the condition of Yuuma’s body immediately.

And then heaved a sigh of relief after confirming that Yuuma was truly unscathed.

The exploration continued after that as if nothing happened and they reached the 32nd floor by the end of the day. They’ll continue the exploration tomorrow but Yuuma and the president felt that they couldn’t advance any further.

◇◇◇

That night, in one of the rooms in Yokohama’s business hotel.

Aisha was touching her chin as she stared at the PC before her. She read the email that she received.

She was grinning alone while sipping on her favorite canned coffee.

The email from IDR(International Dungeon Research Organization) was sent to every single researcher in the entire world. The content was about the change in the “Orpheus Slate”, and also asking for the information about newly appearing 『Black Dungeon』.

""

It was an email that she received around half a year ago. Aisha forgot about this email since she was only interested in the research about the 『Black Dungeon』, thus she was only reading this particular email around this time, half year after she received it.

But then, she recalled about this unread email again after she heard about 『Tiny Dungeon』 in the garden from Yuuma.

「The date in which he defeated those 『Coloured Slime』, and then the date of him defeating the 『Huge Slime』 that appeared last is coincided with the date of the subjugation of the duke, lord, and king.」

―― On top of that, there’s that abnormal 『Metallization』 ability. 『Liquid Metal Transformation』 which made him even more abnormal, and that aberrant amount of 『Mana Index』 which allow him to use magic on the ground… No doubt about it.

「He’s the seeker who subjugated the 【Black King】」
