Indeed, Ye Xiao himself was not fully confident about this matter.
At least, he had not been confident before, and his previous plan was not what it is now, which was to directly threaten the immortal sects into handing over their possessions.
But, during his moment of epiphany in the courtyard, the Rebirth Ring intervened in Ye Xiao's enlightenment, and it endowed him with benefits more than a hundred times that of his initial epiphany.
This was what prompted Ye Xiao to have such thoughts now.
Such a state of epiphany was only likely to be induced by one of the top ten sacred medicines, the Dream Dust, for cultivators.
Yet, the Rebirth Ring could steadily affect the gains of Ye Xiao's epiphany.
Just this point alone was enough for Ye Xiao to ascertain that the capabilities of the Rebirth Ring were far beyond what he currently understood.
This included the Mountains and Rivers Awl held by Zhuge Xiang.
