"What is going on?" Although Jiu Simeng was quite proficient in medicine, she only knew a bit about Spells, "It clearly looked like a cliff, how could it possibly...?"
Qiang Ba interrupted Jiu Simeng, speaking, "This cliff is merely an illusion, it doesn't actually exist. If we use our powers to become invisible, we can exist in the same space as the cliff, allowing us to pass through."
After hearing Qiang Ba's explanation, Jiu Simeng was still very confused, only grasping some of it. She understood that in the Otherworldly realm, illusions existed, and this particular illusion stored things in another parallel space. The object itself did not exist; it was simply a shadow refracted from the parallel space and projected into their space, making it seem as though it truly existed. However, to break this illusion, one would need to enter that parallel space themselves, and the power users used invisibility by exploiting the existence of parallel spaces.
