Frost jade essence

Frost jade is only a rank five Gu material, but frost jade essence inside it is a rank six immortal material. Almost every frost jade holds essence at its center, and Fang Yuan takes the jades without first extracting it. Larger essences include thousand year frost jade essences, which are rank seven Gu materials. ^{ch. 1312}

Fang Yuan obtains a large haul of frost jade and frost jade essence from Frosty Peak and considers building a Mini Frosty Peak in Mini Southern Border. He sells frost jades and frost jade essences from that plunder, along with ice path mortal Gu, when funding dragonfish expansion. ^{ch. 1313}
