Audacious!
Outrageous!
Impossible!
If any Alchemist knew of Wei Wuyin's intentions, they would outright deny the possibility without a second thought. Utmost Purity Mist was a divine material born from the Alchemic Dao, the only natural manifestation of alchemical energies and essence with limitless assistive properties, and was used in the refinement of high-quality cauldrons to Solar Stars to uniquely-crafted radiance belts.
But the requirement for even grade one mist was insidiously difficult, and its very existence was contingent on flawless, consecutive successes. During the Spiritquake, which was caused by Wei Wuyin's experimental usage of a transcendent product to replicate his insane Soul Idol Tribulation, multiplied by four, the concoction process of the Everlore Association's alchemists' White God Cauldron was ruined due to a single impure product!
A single impure product!
