The Jade Stone was shrouded in a layer of Immortal Light, and the spiritual power contained within it was incomparable to even billions of Top Grade Spirit Stones.
The main point was that the quality of spiritual power contained within the two was vastly different.
It was hard to imagine such a small piece of Jade Stone containing such a vast energy.
Ye Xuan called this kind of Jade Stone Immortal Jade, and the power it contained far surpassed ordinary Spirit Stones.
Ye Xuan sat cross-legged in the center of the world, holding the Jade Stone in his right hand, carefully scrutinizing it, while also sensing the changes of the character 'Immortal' in his mind.
Whenever Ye Xuan touched the Immortal Jade, the character 'Immortal' would always emit even more immense energy, causing Ye Xuan's Emperor Soul to restore rapidly.
And when Ye Xuan distanced the Immortal Jade, the character 'Immortal' would return to normal.
