"...If you can't understand a demon, don't try to fight it."
Ample experience had led her to make the most appropriate choice.
If it were a creature with obvious intelligence, she might have tried to negotiate or communicate, but this visibly aberrant scene made her choose to remain invisible.
Even having lost her sense of direction, she still silently pushed forward.
With her abilities and the supplies she carried, even spending several days here would pose no problem.
"...There's something wrong with the fog."
Given her pace, even without running at full speed, after moving rapidly (invisible) for several hours, she should have reached the boundary of the city.
Thus, it was mostly the "fog" that not only interfered with her perception and sense of direction but also likely used illusions to disrupt her vision.
"As I thought, I've been here before..."
Seeing the same scenery she had cautiously recorded reappear, Hua Xueyi confirmed she probably had been tricked.
