Arisa, it's about time."
"OK."
The sand giant that Mia manipulates crumbles after losing all its health.
There, I use [Labyrinth] magic to buy us some time. It can only keep it for 30 seconds at most, but it's enough isn't it.
I can smell honey drifting from Mia who's drinking an MP recovery potion beside me. It's honey taste for this child huh. Everyone's asked to change the potion according to their preference eh.
This time, the sand snake that's been created from the crumbled sand constricts the Thunder Squid.
"Lulu, start the preparation."
"Un, okay."
I prompts Lulu who has supported everyone with magic to start the preparation.
I also restrict the Thunder Squid's movement with space magic.
However, my aim isn't the Thunder Squid. It would resist if I directly aim on it wouldn't it.
I aim at the sand snake constricting the Thunder Squid. Stopping the sand snake indirectly restricts the Thunder Squid.
I take the MP recovery potion from the pouch and gulp it in one sitting. Bitter.
Its health should be under 30% if Lulu's accelerated bullet hit. Before it enters the Rage (Stampede) state, I will use the big magic [Space Annihilation (Disintegration)] while using all my unique skills and end it in one go.
Lulu sets up the smoothbore gun she has taken from her pouch.
I nodded to Lulu who asked with her eyes and gave her the GO sign.
"Finished aiming. Secure."
『Yes my lady, Dimension Pile stand by』
Support sounds from the smoothbore guns answers Lulu's order.
The invisible dimensional stake secures the heavy smoothbore gun in the air.
"Spread out the virtual barrel."
『OK, Virtual Barrel spread』
20 meter-long force gun barrel is expanded in front of the smoothbore gun.
Kuh, I'm burning up!
"Acceleration magic circle, limiter release."
『Aye aye ma'am, battery full charge』
The magic cylinders attached on the smoothbore gun are being filled with magic power in order to create magic circles.
Huh? It's usually enough with one, but aren't all the cylinders including the spare one used this time?
『Acceleration Over Drive』
Red magic circles are being deployed alongside the virtual barrel--wait, why so many!
Huh? Weren't there supposed to be only three magic circles?
Aren't there 100 of it coming out?
"Preparation complete! Arisa?"
Lulu who had finished the preparation asked for the timing. Of course it's a GO.
I order her to shoot while pointing at the Thunder Squid.
"Shoot!"
『Ignition!』
Lulu pulls the trigger with her small finger, and then the shell is fired.
BOMBOOM, Lulu's smoothbore gun is shot while leaving blue trails and earsplitting explosive sound.
Eh? It's a substance bullet right?
Why is it like laser?
Uwaah, there's a huge hole opened on the Thunder Squid's body with just that one attack.
The part around the big hole is gouged inward, you can see behind the Thunder Squid through it. Finally, the Thunder Squid is shredded into slices by the hardened sand snake.
Geh, isn't the labyrinth floor hollowed in straight line until the end wall!
Right then, I heard the voice of our carefree master.
"Mach 20 really is amazing isn't it."
Mach? By 20 that means exceeding the speed of sound by 20 times?!
Restrain yourself a bit more hey!
But I'm too shocked, I can only let out stupid words like au au from my mouth.
"No well, I heard that railgun was 20 mach, so that smoothbore gun is the result of me trying out whether it can be materialized with magic you see."
That explains why there's no rifling.
"Arisa~"
"Let's do the victory pose!"
Eh? It's over with just now?
Lies? My turn is.
I haven't used that unique skill yet.
My hands are pulled by Pochi and Tama toward the center of the hall where the treasure chest appears, and then we take the commemoration photograph in victory poses. We took the second one with our masters together.
Thus, we obtained the Mithril Plate.
