Within the mind space, Musk was moving as though dragging himself slowly trying to obtain some new ability but he could only see the stars in the distance.
Compared to the last time he came to this place, it seemed to have changed greatly and he could even feel that the distance he had to move was too great.
He also did not even realize that the previous ability he had gotten had been improved just by default, but it probably is understandable due to its nature.
An increase in the mind state was enough to improve it, and it can also be said to be another method of improving abilities.
But it was indeed not that useful if one accomplished things in this manner as the ability seemed to lose its meaning, after all when one improved an ability to perfection they could allow the mind state to keep rising and then a breakthrough to the next state is faster this way.
