"If I wanted, I could turn everyone in the Four Continents into gals in my eyes, and by then I..."
...
Zhang Ze remembered that he didn't finish bragging at that time, because Li hit him with a stick and knocked him off the mountain.
Thinking about it now, it wasn't because Zhang Ze missed his master or the gals.
It was because he suddenly realized that the magical ability of these black stones to alter cognition seemed somewhat similar to the methods of a Void Refining Cultivator...
The black stones were just the medium, the real effect was brought by the dust crystals extracted from the black stones by Lily and the others.
These dust crystals, after receiving the desires and thoughts of the first observer, would solidify them and change how the surrounding people perceive them according to this idea.
Although it only altered perception, it couldn't really turn stones into pants-less figures like his master could. (If Li wanted, he truly could.)
