"Master Wan, this Blood Jade Rejuvenation Pill must be a high-level elixir, right? It's quite valuable; we can't afford it."
High-level elixirs are extremely precious, and each one requires an Alchemy Grandmaster to consume a significant amount of Spiritual Medicine to create, a process which is both time-consuming and laborious.
Moreover, high-level elixirs are prone to causing the furnace to explode.
Intermediate elixirs, as long as the materials are correct and the Alchemist's skill is without flaws, almost never encounter any problems.
But high-level elixirs, due to their powerful inherent medicinal properties, even an Alchemy Grandmaster cannot guarantee that every batch will be successfully produced.
A slight instability can cause the furnace to explode in minutes.
