After he limited its coverage to only his hand, Toz found it a lot easier to control and change the structure of his consciousness, but he still didn't seem to be able to achieve what he wanted. Since he made minimal progress, Toz had a hard time maintaining his absolute focus and his thoughts wandered.
He absent-mindedly wondered if he could use his consciousness in combat. Not by having it absorb mana at the same time as he fought, but as a way to attack his enemies. After getting that idea, Toz almost wanted to try it out immediately. But there weren't any suitable targets around. If it worked as a means of attack, Toz doubted that it would work against the Adaptation Trees.
Toz also had to mind the fact that the cats were delaying their rest to let him practice his passive training, not for him to play around.
