Days and days have passed. Cairo already forgot the outside world. He was fully immersed in his training. It was literally the only thing in his mind
At first, the training was quite hard but as time goes on, it becomes easier. Cairo becomes more and more used at enduring both the gravitational and spiritual pressure while fighting the metal ball
A lot of his aspects were improved by a huge margin. The only thing that worries Cairo a bit was the time needed to conquer the 41st floor. Before he just randomly entered one of the floating islands but there are more than one of them
If the pressure on those islands are stronger, Cairo really needs to spend tons of his time into this Tower
Normally, that wouldn't be much of a problem since there are still his clones with the same level of intelligence. However, this meant that he wouldn't be able to climb the top of the Tower if that is even possible at a short time
