Gu Jin didn't answer right away. She stood very still, her eyes scanning everything around them, the trees, the rocks, even the air itself. Her mind was sharp, and she started noticing tiny things that didn't match.
"Look," she pointed, "that tree over there has no shadow. But everything else does."
Mimi squinted. "Huh? You're right!"
Gu Jin walked over to it. "It's a fake. Just part of the illusion. This place is trying to trick us into walking the wrong way."
She touched the tree. Her fingers went straight through it, like it was made of smoke.
"That proves it," Gu Jin said. "Some of the things around us are fake, just like that ghost earlier."
Mimi looked nervous. "But if the trees and rocks are fake, how do we know where to go?"
Gu Jin took a deep breath and closed her eyes. She didn't rely on what she could see, because that was being fooled. Instead, she focused on what she could feel.
