Instead of frowning, his figure remained unmoving.
He just didn't get affected by the illusions at all, as such he finished waiting for a change. In the end, his sight bypassed the illusions, and could see a figure seemingly suspended in the sky.
In his line of sight though, the woman's situation was far from just being suspended in the air, as she couldn't move. Her eyes however seemed to remind him of something, as one was purple while the other grey.
Clearly this was the same as him using the Black and White Lotus Technique. But he couldn't be sure if this was the natural state of her eyes, after all he had attained through a cultivation technique of the soul.
The eye color of his could change when he wasn't using the technique, and the situation might be different for the woman. It was just that he lacked any interest in finding out if this was the truth.
