Saleos took a deep breath and meditated Dean's words. There is no doubt that he is the strongest, but it is also true that he can't use all his power. If he had total control over his strength he could have beaten the young Evester in seconds.
"But why a prison cell?"
Saleos asked as he sat on the ground. There were many places for him to train which have even harsher living conditions than a prison cell.
"Because in a prison cell your mana is sealed and you will only focus on making your body adapt to the amount of power you have."
Dean was sure that Saleos could be even more strong if he follows what he was saying. There is something he will also gain by the absence of Saleos, and he is sure by the moment he will come out of prison the world would have changed.
"What are you plotting Dean?"
