Jade root soil

In Hu Immortal blessed land, Fang Yuan fills the air bubble fish lake with jade root soil. Held in the hand it is icy cold, and if squeezed tightly it turns into jade. Ordinary jade root soil forms qi veins that resemble human blood vessels and also look like the roots of ginseng, which is a reason for the name. Air bubble fish living in that environment live longer and are much more vigorous. Because of that soil, the lake is called jade root lake. ^{ch. 825}

Jade root soil is a Gu refinement material. It is not an immortal material, yet filling a large lake takes a large purchase. ^{ch. 826}
