The Demon Hall's ordinary experts probably lacked such strength.
Only those Hall Masters who were invincible beneath heaven possessed such ability.
After gaining a little understanding of this formation, Huang Xiao continued searching for clues to the place of seclusion.
This time, he did not fixate on the sights before his eyes.
The trees he saw might very well not be trees at all. In reality, they might be rocks, or even people walking through Supreme Demon Peak.
It was only because of the formation that what he saw of them became a tree or a blade of grass. Anything was possible.
Even if the two of them bumped into each other, neither would feel that they had encountered the other.
They would merely feel that they had bumped into a tree or a rock, or even that there was nothing there at all.
Just as before, when he stood before the wild boar, it had not noticed him at all. Even when he touched it, it showed no reaction.
Yet when he struck, he could still kill the boar.
In other words, if he could thoroughly comprehend this formation, see people outside it while remaining within it himself, could he kill without leaving a trace?
If things truly worked as he imagined, then whoever he wanted to kill would be like that wild boar, unable to discover him or even notice when he touched them.
And he could kill them with ease.
If this formation could work on a single person, letting me see others while they couldn't see me, wouldn't I be able to kill anyone I wanted? Huang Xiao marveled inwardly.
But these were only thoughts. The formation here had probably cost untold resources to establish. Normally, such a formation could only be fixed in one location.
