You could say a top-grade Profound Stone was equivalent to a single Eighth Grade Profound Qi Pill.
A treasure of this caliber would be no cheaper than a Tier Nine wonder of heaven and earth. If one were to appear, even a Tier Nine Martial Emperor would covet it.
What a pity!
At the same time, everyone secretly felt it was a shame.
There were far too few top-grade Profound Stones in Mu Jin's Restriction Array—just a single one. If dozens or even hundreds had appeared at once, it would have been enough to help Mu Jin break through to the Tier Eight Third Layer, perhaps even reaching the Tier Eight Triple Peak and advancing toward the level of a Nine Heavens Martial Emperor.
Of course, top-grade Profound Stones were inherently rare. For even one to appear was already an unexpected event.
