"This... I don't think there's any Element that can do this. Although there are some tricks with enough preparation, I should've sensed it." while the Guild Master was speaking, Avion drank the tea again.
However, he forgot that it was hot again which burnt his tongue, "Ouch!"
'Precious!' even during bafflement, Matteny's gaze didn't change.
After sipping few by few, Avion pushed the tea again and it was half-full. When everyone's eyes were on it, it became full again.
'A true bottomless drink!' everyone thought.
"Is that enough proof?" Avion drank again. His tone full of confidence and even some arrogance with his smug look, "Ouch!" but forgot that the tea was hot again for the second time.
'PRECIOUS!'
"I... I guess so." at this point, the Guild Master was convinced. Thinking about it, albeit seemingly improbable at first, it makes sense!
