Magic heavy machinery is cool?

 
 To refine the magic black stone, we obviously need ore as a material. But this is really no problem. The magma here is already known to be used to make magic black stones.
 
 ”Uni, please.” (Wirk)
 ”Uni~♪”
 
 As if to say “leave it to me”, Uni consciously concentrates and sets his hand upon the ground.
 
 ”However, I was thinking about it the whole time, but you really have a brownie in your employ.” (Jay)
 
 Apparently, Jay’s interest in Uni seemed strong. Brownies are also said to be fairies who live as one with the ground. Dwarves are a race that is similar to that, so I guess they feel a sense of closeness.
 
 ”Uni!”
 
 Then we moved according to Uni’s guidance. He pointed to one part of the wall within the workshop. So it’s this nearby.
 
 ”What’s he saying?” (Jay)
 ”The wall area here has a lot of ore with the component for magic black stone. Is it fine to dig here?”
 
 Because the dwarves’ dwellings are dug inside caves in the mountain. Additionally, there’s flowing magma from the active volcano. It’s not strange for there to be ore that’s the material for the magic black stone. Uni did a splendid job of detecting it.
 
 ”… if that’s really true, then I guess it’s alright.” (Jay)
 ”It will be. Alrighty then, let’s begin.” (Wirk)
 
 Since I got Jay’s permission, I asked Uni and the moles to begin the digging work. Uni applied his magic to stop the mountain from collapsing.
 The excavation is done by the moles and I. Now, let’s also use heavy machinery. Since we’re excavating horizontally this time.
 
 ”Alright, here we go! Magic Tunnel Drill Giant!” (Wirk)
 ””””””””THE H**L’S THIIIIIIS!””””””””
 
 The dwarves’ surprised voices all matched together as the bracelet changed shape. Maybe they were surprised that it was a slightly larger heavy machinery.
 This magic heavy machinery is the most optimal magic heavy machinery for excavating a tunnel. It’s a cool and rugged magic heavy machinery, furnished with various drills at the ends of multiple arms. It’s been such a long time since I’ve used it, so my tension is also at max!
 Incidentally, the drill part of this heavy machinery also has an explosion construction technique applied. If I use this, the explosions can even excavate solid bedrock.
 It can also be used in a fight, but I can’t expect it to be as agile as the magic excavator. Calling it a fist fight is a weird way of phrasing it, but if we ignore avoiding attacks, then it may be used to focus solely on attacking.
 Now, this tunnel drill giant is also equipped with a conveyor belt so it can collect the excavated minerals.
 
 ”Go-!”
 
 Kobelco was extremely excited. He seems to also understand how cool this thing is.
 
 ”It’s somehow really awesome-noja.” (Bamboo Princess)
 ”So, Papa? This is Wirk’s magic!” (Eph)
 ”No, it’s not magic, it’s heavy machinery.” (Wirk)
 
 The Bamboo Princess was astonished. Then Eph spoke to Jay near her while puffing out her chest. But I corrected her a bit.
 
 ”Tsk, I guess it’s cool…” (Jay)
 ”Huh?” (?) [TL: Could be anyone…]
 ”Ooh! So you understand how cool it is!” (Wirk)
 ”Hmph!” (Jay)
 
 Although Jay was frowning, he complimented the magic tunnel drill giant. I was a little happy, but he immediately switched to a cold expression and turned away.
 
 ”That d-, doesn’t specifically mean I think it’s cool!” (Jay)
 ”Didn’t you just say it was cool!” (Eph)
 ”F-, figure of speech!” (Jay)
 
 Eph and Jay began quarrelling between each other. It’s really pointless.
 
 ”Alright, anyways, we’ll begin. Since we’re going to do this, shall we compete to see who mines the most?” (Wirk)
 
 I called out to the the moles that’ll also dig with me.
 
 ”””””Mogu mogu mo-gu~!”””””
 
 The moles enthusiastically accepted my suggestion. Because moles are also tunnel-digging experts.
 
 ”Koo~!”
 ”Kyupi~!”
 ”Umu. Kani and Keon are also cheering for you-noja!” (Bamboo Princess)
 
 Kani, who was on my shoulder, and Keon, who was being hugged by the Bamboo Princess, were shouting for us.
 Now then, I guess we’ll begin. My drill immediately spewed fire! The wall was excavated with a tremendous drilling sound.
 
 ”S-, so fast!”
 ”Isn’t that waaay fast than gnomes!”
 ”That youngster’s magic heavy machinery is a monster!”
 ”Mu, now that you mention it, I’ve heard about that before.”
 ”What? Do you know it, Rai—”
 
 The dwarves’ voices reached our ears, but the drilling excavation continued regardless.
 The moles were doing their best, but the magic heavy machinery’s excavation speed was fast. Even so, everyone did their best, and we managed to collect a considerable amount of ore in an hour.
 
 ”Mogu~”
 ”Mogyu!”
 ”Mo~gu~”
 ”Mogu mogu!”
 ”Mogu-!”
 
 Although they lost the competition, the moles instead surrounded the magic tunnel drill giant and praised it.
 The moles also certainly mined a considerable amount. They were helpful enough.
 
 ”So, Papa? Amazing, isn’t it?” (Eph)
 ”…..” (Jay)
 
 When Eph asked Jay once more, he was astonished and couldn’t get any words out.
 
 ”W-, well, even a dwarf could do that much if he felt like it.” (Jay)
 
 Then what finally came out was a monologue that seemed like a bluff. [TL: surprise, surprise, our MC has some sense]
 Well, nonetheless, the important part definitely starts now…
