According to the division of the alchemists in the glazed avarice Empire, a ninth-grade Alchemist would be considered qualified if he could refine a mid-grade pill in three cauldrons.
For an eighth-realm Alchemist, he could produce one high-grade pill after three attempts.
The requirement for a seventh-grade Alchemist was to open the furnace ten times and be able to stably produce at least one high-grade pill in each furnace.
For a sixth-grade Alchemist, the requirement was to open the furnace ten times and produce a Supreme-grade pill.
As for a fifth-grade Alchemist, he could produce ten Supreme-grade pills after ten times of opening the furnace!
As for the fourth-grade Alchemist ...
Not only did it require alchemy skills, but it also required the alchemist's own cultivation.
Otherwise, not to mention a grade eight Spirit Fire, even a grade seven Spirit Fire would not be able to refine some medicinal materials that had aged for a long time!
