Master Artemis was shocked once again when he set his eyes on the Heaven Grade Cauldron that Karsha had taken out. He was the leader of the Alchemy Guild in all of Sunlight City, yet even he didn't own a Heaven-Grade pill furnace.
Karsha, noticing the old alchemist's reaction, smiled; he could tell the old man truly was knowledgeable. The fact that he could identify the grade of the furnace meant a lot.
Unlike weapons, which can easily be identified, cauldrons are much more complex. They can't be appraised just by sight; they must be tested to determine their grade. Seeing Master Artemis recognize the furnace's grade so quickly made Karsha understand one thing: the Master was indeed knowledgeable.
'It was only a pity he wasn't able to tame the Heaven Grade pill flame,' Karsha sighed inwardly.
