"There you go", Val nodded, smiling. "The less energy you use, the more spells you can cast. The more spells you can cast, the more you will practice how to channel your energy, which will enable you to cast more spells more efficiently".

"I see", Adrien said. "Somehow it's harder to do this than to burst out all at once", he then chuckled.

"For you, at least", Val giggled; and Adrien couldn't help but blush a little hearing that. "...But it will become easier as you keep doing it. It is just like training for a marathon: the beginning is always the hardest part".

"I don't know, I'd say every part of doing a marathon is the hardest part!", Adrien said.

Val burst into laughter. "A fair point", he chuckled. "In my defense, I never said that any of this would be easy... However, trust me: after some training, you will begin to do this effortlessly. It will become second nature for you".

"I hope so", Adrien said, a little frown on his forehead.

"Trust me", Val smiled.
