Perceiving the presence of alien powers in the environment, the pages of the Ancient Secret Scripture slightly glowed, just like before, swiftly absorbing the remaining power from the traces.
Feeling the last bit of alien power in the traces gradually disappear, Anvis hung the Ancient Secret Scripture back at his waist, walked to the power-depleted trace, crouched down, and touched the bottom of the ground where the trace was.
What he felt was a strange, talc-like powder texture, as if the rock had transformed into extremely fine dust, seemingly disintegrated by an incomprehensible force.
Anvis shook his fingertips, and then the dust on the ground, as if suddenly acquiring life, gathered itself into a small sphere.
Then, the small sphere floated up, hovering beside Anvis.
This could very likely be the trace left by Evan's past visit, or possibly when he commanded his family guards to move a statue.
