Fang Lin still remembers, within the Pill Saint Palace there is an ironclad rule: if the Palace's Pill Refiners have irreconcilable conflicts for various reasons, they can apply to the Great Elder for a life-and-death Pill Fight.
Once the life-and-death Pill Fight takes place, the victor will survive, while the loser will perish, with no room for reversal.
This ironclad rule was created so that the Pill Refiners of the Pill Saint Palace could resolve conflicts based on their own alchemy expertise, without any external interference; life or death relies entirely on one's own skills.
Of course, applying for a life-and-death Pill Fight is not so easy. The Great Elder will personally investigate the matter thoroughly before deciding whether to consent to the life-and-death Pill Fight. If the Great Elder disagrees, then the life-and-death Pill Fight cannot proceed.
