Since creating two hands made it easier to interact with the mana, Toz continued pushing his consciousness to its breaking point so that it became stronger each time it recovered. It took a lot of time to improve significantly, but it didn't look like he was leaving his cell anytime soon, so it didn't matter. Toz almost wanted to stay longer in the cell since it provided such an excellent atmosphere for concentrated training.
The absolute silence, the dull walls, and the otherwise boring room ensured there was not a single distraction anywhere. However, there were five distractions that Toz didn't want to spend a minute longer without being able to reach. The cats weren't the only thing urging Toz to continue training. But they were what made him focus on breaking the restriction as soon as possible instead of only getting stronger.
