After Lucy finished his report, he took a quick nap before disappearing again. Although he had found the most likely suspects, he hadn't uncovered their plan or discovered any information that would be useful in stopping them.
Now that Lucy had found a clue, it would at least be a little easier to unravel the rest of the mysterious conspiracy. Toz was only worried that Lucy would become too eager and take unnecessary risks and put himself in danger. And while there might not be much Toz can do to prevent that, he can prepare himself in case something untoward happens by becoming stronger.
So after Lucy left the tent again, Toz began training.
The last time he trained, he had pushed his lightning mana to the limit of the fifth level. The way he had gone about doing it had also injured his mana pool a little since it was a recklessly stupid method. But now that he had recovered, Toz was more than ready to bring his lightning mana to the sixth level.
