"Hmm… Let me think about this while watching your elements in play," William didn't rush and tell her any of the techniques he knew. As a start, he didn't know if human techniques were suitable with monsters or not. Besides, he felt like she was playing with him.
"How come you don't know any technique? How come you used your powers back then?" This point puzzled him. Even when he asked while putting into his mind she was toying with him most probably, he never expected to get to know a secret about monsters.
"We don't perform techniques, we just use the elements purely and out of our imagination," she said lightly, as if she was saying something normal and common like walking, sleeping, and eating.
Yet William couldn't help but get his eyes slightly widened and his eyebrows raised. "You can't be serious, right?" He looked at her again, assessing if she was telling the truth or fooling around.
