Yang Xiao took out the Human Bone Staff and, following Jiushan Cangxuan's instructions, began attempting to perceive the fluctuations of spiritual power emanating from him.
"Have you sensed anything?" Jiushan Cangxuan asked.
"No, there's no spiritual power feedback from you at all, it's as if... as if you're an ordinary person." Yang Xiao replied truthfully.
"And now?" Jiushan Cangxuan asked again.
This time Yang Xiao sensed something, but it was very weak, estimated to be at the level of a Resentment Level Apostle, the kind that even alchemists would disdain to use.
But soon, Jiushan Cangxuan's spiritual power gradually increased, from the Resentment Level to the Fierce Grade, and then to the Ghost Level, and in just a dozen seconds, it stabilized steadily at the power of the Netherworld Realm, then it became vast as the sea, just feeling it through the Human Bone Staff was terrifying.
