It was indeed surprising for Lu Chen that his Hateful Heaven Pupil Technique proved ineffective, stirring up immense astonishment within him.
However, he didn't dwell on it for too long, considering that the previous visibility beyond the Formation might have been due to the Xuan Pearl being placed over the formation's key node.

Though invisible, Little Black possessed the innate spiritual sense of a demon beast and could sense danger.
Little Black poked its head out, stared at the cave for a long while, eventually nodded, and said, "Master, I didn't sense anything off. But you did mention that this place is an Illusion Array, so I'm worried I might not be seeing things clearly."
