I tried moving forward.

　The radar in my brain didn't let me move at all, and I was still superimposed on the enemy's light spot.

　To test it out, I loaded up my tracking rounds and fired.

'Whoa!'

　After the tracking round went straight for a bit, it made a clean U-turn.
　I dodged it on the spur of the moment - and it followed me further.
　While admiring its tracking performance, I knocked down the approaching tracking rounds with my normal bullets.

　Even now, while fighting off the intermittent damage, I think about it.

　The fact that the tracking rounds are aiming at me, at least the situation where the mini-radar in my brain is visible, and me and the enemy are overlapping, seems to be a certainty.

　If that's the case, you can't attack properly.
　I tried to move towards the staircase, but I couldn't make any progress from my perceived position.

"Well, what should we do now?

　As I was walking around aimlessly, thinking about whether there was a breakthrough or not - it moved!
　I turned around and walked in the distance towards the stairs and was able to move.

'Do you want me to move back?'

　So I walked away again, but this time it didn't move.
　I wondered what that was all about earlier, and this time I was able to take a step to the left.

'......'

　Stop completely and consider the possibilities.
　I came up with a possibility and took a step back and forth and left and right.

　Then I was able to move to the right this time.
　And then left.
　I could move backward twice, and then I could move forward once.

I see.

　I think I'm starting to get it.
　A piece of paper like a piece of graphite appeared in my head.
　It could move in only one direction out of four directions (front, back, left and right).

　I tried eight directions, but I couldn't move in all four directions.

　After trying again and again, I found out that I could only move in one direction.

　I tried to move only in the direction I could move.
　The mini-radar in my brain showed me moving in a completely random way.

　It's good that I can move ...... now that I can move.

'When will I be able to go home at this rate?'

　I mumble with a smirk.
　Even at this moment, the attack is still going on, ......'s still good.
　You can get by with the Absolute Rock stone and the few recovery rounds that are still left, though they are running low.

　The problem is that we can't advance forever.

　Three steps forward, two steps back - that's not easy.
　It's like taking three steps forward and three steps back.

　What if the direction of travel is completely random.
　Even if you go on and on, you will only end up stamping your feet in the same place.

　If I had a dozen or so steps to go, I could handle it, depending on my bias (luck), but I had a few hundred steps to go from my current location to the stairs.
　It's impossible to keep going at this rate.

　There's got to be some way to move forward, even if it's unavoidable.

Oh.

　Huh, and then I remember.
　There's a way to force yourself to move forward, right?

　I'm going to take the grenade out of the grand eater's pocket and shoot it.
　I grab it.

　I wait for a while - and then I advance.

　I grabbed the bullet, and I made a small step forward.
　I kept firing at the bullet.
　I grabbed it and moved forward, inch by inch, inch by inch.

"......

　I stopped halfway through and tried to take a step forward.

　I couldn't do it, so I used an ironclad bullet to take one step forward.

　Then I stopped again and went forward - this time I went forward normally.

　Again, my brain's radar looked like a piece of graph paper.

　It was fixed that I would only advance in one direction for each square that stood up.
　If you move to a different square, the direction of forward movement is reset, regardless of how you move.

　If you can move forward, you can go forward normally, and if you can't, a bullet will grab you and carry you to the square.

　After a few hours of repeating the process, I finally reached the stairs.
　Finally, I reached the stairs.

　I continued up the stairs and proceeded to the upper floor, and the moment I was still on the level, my vision returned and I felt the monster fall.

　The exact same feeling I remembered from the first time I pushed the skeleton out of the dungeon.

　The monster that possessed me disappeared at the same time I went up the hierarchy.

　And then--.

'Ah, the mirror.'

　The mirror that the monster supposedly dropped fell in front of me.
