I figured out a pattern.
I had asked Johnson about the exit of this tenth level which he didn't answer of course.
But I was never relying on the chief guard anyway.
My bets were on Jack and the ghost delivered it.
He read Johnson's mind and told me where the exit of this level ten was.
It was behind the cupboard of Johnson' cabin.
And the exit of this prison altogether was from the door behind the cupboard of the Jailor's cabin.
Therefore, the pattern I figured out was that the exit of each level was behind the cupboard of the most authoritative figure's cabins of those levels.
The chief guard of this tenth level was Johnson so his cabin had the exit.
And now, I will make sure that I reach his cabin.
But for that, I had to deal with these hundreds of guards standing in my way on the corridor.
I had to cross them to reach the other side and the only way to do that was to hurt or kill them.
However, before that…
"Where is your cabin, Johnson?" I asked.
