"What's going on here?" Dreams may be well-versed in medicine, but she only knew a little about these spell actions and chuckled, "It's clearly a cliff, how can it..."
Qiang Ba interrupted Dreams, saying, "This cliff is just an illusion; it doesn't truly exist. If we use our abilities to hide our forms, we can exist in the same space as this cliff, and then we can pass through."
Dreams listened to Qiang Ba's explanation and was still very puzzled, understanding only some of it. She learned that in the Otherworldly realm, illusions existed to conceal things into a parallel space. Those things did not actually exist; they were mere shadows refracted from the parallel space into their own. What looked like a real presence in their space was just the effect of that refraction. To dispel the illusion, one needed to enter that parallel space, and a power user's invisibility was a use of that parallel space's existence.
