Sun Wukong did not notice Hong Jun Daoist Ancestor and Goddess Nuwa hidden among the demon crowd; in fact, even if the two were standing in front of him, he probably wouldn't recognize them.
In his dream, Sun Wukong had once seen the appearance of Goddess Nuwa, but both she and Hong Jun Daoist Ancestor had restored their youthful appearances upon arriving in the Yuan Realm, appearing as handsome young men and beautiful young women, not at all like the immortal-style, crane-haired, child-faced Hong Jun Daoist Ancestor or the human-bodied, snake-tailed Goddess Nuwa.
Moreover, to be honest, Sun Wukong currently had no spare time to care about who was watching the battle; the assaults of the Heavenly Prince's Formless Sword Qi were becoming increasingly fierce with each strike. There was a substantial disparity in cultivation levels between him and the Heavenly Prince, making it extremely difficult for him to fend off the attacks.
