Kael did it several times through the hours, steadily increasing the essence pressure each time until Azaroth couldn't tell when he stopped and when he started increasing pressure again.
Azaroth had since gotten used to the sudden jerking of his muscles, the way his joints locked together, and how he was left twitching each time after sessions of pressure on his core.
His small body had never sweated so much, his muscles had never relaxed and turned rigid the next moment from pain like this before. Azaroth's uniform was torn with strips burned away, and his sword was no longer by his side.
His chaos core hadn't been put through pressure but oddly enough it was...changing too. Just like his normal core was getting smaller, tighter, and harder like a shrunken tiger nut.
"Anytime now." He heard Kael mutter just before Alex grunted sharply in pain as Kael began another session on him.
