"At first glance, it really does look a bit like human bone marrow..."
Zhang Yao's expression subtly changed.
The Thousand Year Jade Marrow is found deep within some large and medium-sized Spirit Jade Ore Veins, and can also be extracted from accompanying ores in some Spirit Gold Ore Veins.
This small cluster is a standard unit, more than enough to construct the 'Celestial Profound Bright Jade Array'.
"Let's begin."
Zhang Yao took a deep breath, removed his shirt, sat cross-legged in the Quiet Chamber, calmed his mind, and regulated his breath.
Moments later:
"Crack!"
Zhang Yao, having finished regulating his breath, crushed the piece of transparent glass with one hand.
As the glass shattered, the Thousand Year Jade Marrow sealed within instantly fell into Zhang Yao's hand, enveloped by his magical power.
In an instant: the spell activated, magical power surged, and the Thousand Year Jade Marrow in Zhang Yao's hand roiled violently like boiling water.
