The others weren't proficient in alchemy and at most had some basic knowledge of it. Thus, they wouldn't think too much about an Artisan and wouldn't know how difficult it was to reach that stage. However, all the mages of Sky City needed to master alchemy as well as magic.
Their status was directly related to the height they reached in alchemy, and it was even more important than their magical strength. Sky City had two Artisans, one of whom was only a 5th Rank Archmage, but his position in Sky City was the same as that of a Heaven Mage.
Not far from there, Jouyi sighed as he answered Raphael's question. "Sir Merlin is really an Artisan. He is the most talented person I've ever met, and he might become a Saint Alchemist after a few decades. He would be the youngest Saint Alchemist in Noscent's history."
Raphael was reverent and no longer displayed his doubts.
