--Hikaru, let's stop a bit here."
I let Hikaru who's breathing roughly to rest, take out an accelerated magic gun and annihilate [Shadow Sentries] and some mixed level 50 [Shadow Knights] with [Holy Bullets].
The bullets hit the wall and got repelled while leaving sound like when you drop waterdrops at hot oil.
....Stopping holy bullets huh, that's quite a sturdy wall.
Still, on top of the increasing enemy level, their spawn rhythm has increased too.
We're just wasting time if this keeps on.
Arisa and the others are not injured for the time being, but on top of not knowing the other party's objective, there's no guarantee that they will keep being safe.
Wonder if I can make a short cut somehow?
I took out a small white knife from Storage and cut the wall with it.
--Yup, looks like it'll go well.
"■■■■■■■■ ■■ ■ ■■■....."
Next, I point a wand made of [True Silver] that has good magic accuracy diagonally toward the wall and begin to chant the forbidden spell of destruction magic [Banishing Perforation].
"Ichirou-nii, the wall here can't be broken you know. The child who came with me in the past said that it had 『Non-Destructive Element』."
I lift the corner of my mouth to reply Hikaru.
We'll see the result soon.
The forbidden spell consumes magic power that equals the Meteor Shower's.
I can't afford the chance of Arisa and the others getting injured so the target's direction is the opposite of them.
"....■■■■■■■■■ Banishing Perforation."
A collapsing phenomenon from the concept of [Destruction] that can't be comprehended by the science I know is slowly destroying the wall.
Judging from the preface of the spell code, it seems to be a spell that recreates the power of dragon fang that [Penetrates all].
--Still, the control of the magic is difficult.
If I lose focus, the power of [Destruction] might even erase me as the user.
I maintain the wand that feels like it'll fly off with my physical strength, enduring until the spell ends.
The wall in front of me has been erased, and many walls beyond it are also bored through.
In the end, it seem to even reach the sky.
"Uwah, you've really destroyed the wall."
Hikaru muttered in astonishment.
I drink a magic potion and calm my rough breath.
This was a test to see whether the wall could be broken with magic, but I used a white knife made from the remain of the black dragon's fang to test whether it could be broken itself.
"Now then, time for the real thing."
I use [Banishing Perforation] once again in order to create a shortcut in the maze-like corridors.
Unfortunately I couldn't pierce through the target location.
Judging from the sensation, it seems the area surrounding the [Master Room] is protected by an Anti Magic type of barrier.
"Let's go."
"Un, let's!"
Together with Hikaru, I jumped into the hole created by the [Banishing Perforation].
