To cultivators this is a top-grade supplementary tool and pill refinement material.
To the demon clan, they would risk their very souls to acquire the Glacial Quintessence created from Myriad Year Glacial Jade. It is a fantastical item capable of protecting them against ascension tribulation. There are an innumerable number of high-grade demon beasts in this world, but there are only a sparse few that are able to survive their ascension tribulation, allowing them to take human form. As lightning is a weakness to the majority of demon beasts, the lightning from ascension tribulation results in a near death sentence. But if evolving demon beasts were to first take a drop of Glacial Quintessence, their bodies will become greatly resistant against lightning for a time, allowing them to better resist the tribulation.
