"So, Medicine Cauldrons have Grades?"
"Of course they have Grades. Look at that red Medicine Cauldron on the display stand—that's a Third-Grade Medicine Cauldron. It can only refine Third-Grade Medicinal Herbs or lower. You can tell a Medicine Cauldron's Grade mainly by the number of vents it has underneath. A cauldron with three vents like this one is a Third-Grade Medicine Cauldron. Likewise, one with four vents is a Fourth-Grade Medicine Cauldron."
Mu Chen was taken aback. 'Only Third Grade? Then why does everyone look so frantic?' He glanced around and saw a crazed look on everyone's faces; they looked like they were one step away from rushing the stage to snatch it.
