"Cauldron explosion?"
Hall Master Feng and the others could not help but clench their fists.
Cauldron explosion is the most fearsome event an apothecary can encounter during pill forging. It is usually due to an apothecary failing to control the energy contained by the medicinal herbs, causing the process to turn violent and uncontrollable.
The moment an explosion happens, the medicinal herbs within, as well as the entire cauldron, will be ruined. The apothecary might also get injured by the impact of the explosion.
The higher the grade of a pill, the more violent the energy contained within, and the higher its tendency to explode during the pill forging process.
