Climbing the Tower with Time-Stop Ability

The moment I passed through the door, what spread before me was a staircase.

There’s still more?

I scrambled up the stairs at full speed.

The overflowing lava came gurgling up the staircase behind me.

I was faster.

I climbed without any danger of the lava catching up and burning me alive.

As I ran, I noticed the staircase was tracing a wide spiral.

Only then did I realize I was inside an enormously tall tower.

I kept climbing.
