Once someone became an S-tier aptitude user, one of the measurements of power would be the size of their internal force frozen star.
The further one got in S-tier, the harder it was for one to become even stronger. The biggest reason for that was the massive gaps between the levels.
When an S-tier aptitude user had just ranked up, through practising, they would quickly realize that their one centimeter in diameter internal force starglobe would quickly become a ten centimeter in diameter internal force starglobe. At this time, ancient warriors would be S9-tier, but if they wanted to become SS-tier then they would need a one meter internal force starglobe.
With that, how wide was the gap?
Terribly big.
The moment they reach SS-tier, the requirement for reaching the next step would be easy. All they needed was to increase their internal force starglobe by ten centimeters.
