The Fixed Star Compass merely classified it as a second-grade top-tier earthly spiritual artefact.
But with so many features in one, Liou Yuan felt its value had already surpassed its rank, not to mention a Foundation Establishment Cultivator.
Even a Golden Core Cultivator would find it hard to resist such an earthly spiritual artefact.

It could even be used as the sect's treasured possession.
"No wonder Purifying Dark Demon could ascend to Foundation Establishment Realm on the first layer of Erosion Land; it must have depended on this Profound Yin Cold Marrow Stone."
"The world is truly marvelous; who would have thought such an earthly spiritual artefact would be born in this godforsaken Erosion Land."
Liou Yuan sighed with emotion.
One can imagine the rarity of the Profound Yin Cold Marrow Stone, yet its existence also posed a risk to Liou Yuan.
