The essence of the Spiritual Artifact was a black sphere about the size of a palm.
At first glance, it seemed quite unremarkable.
And within it, there seemed to be no energy fluctuations whatsoever.
Yet Luo Changfeng was very clear in his heart.
This was merely the case when the "black sphere" was not activated.
If he were to activate this "black sphere" before his eyes—
The energy it would unleash would at least rival the full force strike of a cultivator at the Mortal Transcendence Perfection realm.
Moreover, this was only a rough estimate made by Luo Changfeng.
As for the true power of this thing, just how immense it was—
Even Luo Changfeng himself was not sure.
After all, he had never tested it.
So it was hard to say.
"Regardless, with this thing in my possession, my arsenal of trump cards has once again expanded significantly."
"It's just that I don't know, what is the success rate of this thing?"
