Near the end of the third day in Silent Prison,
Kardama became completely adapted to mana and aura. He can now freely control them at his will.He can also detect them using his soul sense.
With that, the only type of energy left was elemental energy. However, mastering elemental energy remained a challenge. Unlike mana and aura, each element had its own energy signature, making it necessary for Kardama to study and understand them individually to gain control.
But he doesn't have those resources available here in this silent prison. So today, he did something else.
The prison is like the inside of a box. It doesn't have a door or window.
