Felix stood still in the cell room as he meditated, he looked half-dead on the surface but he was just in a highly entranced state, a few months had passed since he had been incarcerated and he started to get used to the life of being a jailbird, he didn't like it but what could he even do?
He did try to strike the bars every time he felt his strength improve a little and this proved to be a rather dumb thing as his organs were shaken again and again, but fortunately for him they also started to endure better as time passed, his already strong body was adapting to the shockwave retaliatory attacks but that didn't mean he started to damage the bars, he was far from it.
