Legend of the Paladin
"No problem. Just leave it here." Medicine Master agreed, "Do you have time? Help me try out the new formula of body tempering liquid that was improved yesterday. Besides, I have to teach you how to use a cultivator's 'pill furnace'. Your two-piece kit of a hot pot and an induction cooker makes my liver ache." Such a nice guy, he'll teach the mc how to properly concoct pills :D Can't keep on using a f*cking induction cooker for real pills, after all.
So now I'm guessing that Altar Master is Thanos? Since he collected the element stones-so the brown element stone is mind stone, reality stone(red), space stone(blue), time stone(green) and the soul stone(gold)? Welp, "Thanos" just needs the power stone(purpur)<=(don't mind me) to wipe out the universe. Buckle Up!!!
