"Don't mention it", Valerion said, smiling. "I can only imagine how draining this must have been for you".

"Yeah -- I would have never thought it would be so exhausting. I mean -- I expected that it would be tiring, but" - he paused to search for the right words - "but not... not in this particular way. I don't know if I can explain it -- I'm sure you know, though".

"Don't worry. I'm sure that right now you must feel as if you've moved a mountain, but, with more practice, this will happen less and less".

"So is it like building stamina?".

"In a very broad sense", Valerion said, tilting his head slightly. "It has actually more to do with how you will be able to channel your energy more effectively, so less will go to waste".

"Oh, I see", Adrien smiled with excitement. "I can't wait to get there".

Valerion burst into laughter - that gentle, pleasant laugh of his. "Hey, now -- you have yet to finish celebrating your first success, and you're already setting new goals for yourself!".
