She has a very serious and stern personality. It has been stated that she has dedicated her entire life to the martial arts and is uninterested in matters such as love and romance. She develops a soft spot for Xiao Yan after their first encounter, looking after him as a older sister would look after a younger brother.
Xiao Yan met Yun Yun at Magical Beast Mountain, where she was fighting with the Purple Crystal Winged Lion King to get the purple crystal. She was defeated by the Winged Lion King.Xiao Yan found her unconscious near his cave and took care of her. Yun Yun offered to introduce Xiao Yan to Gu He, but he refused. She then saw that his Qi Method was a low-tier one and thought that she would help him out with it.
She left the cave to take a bath thus drawing wild beasts to it. Xiao Yan lured them away but received heavy injuries. Yun Yun took care of him during this time even though she was not accustomed to it. When making food for Xiao Yan, she accidentally added the aphrodisiac he had made previously. This made them uncontrollably lustful as Yun Yun could not control her Qi because of the Winged Lion's Seal. However with Yao Lao's help, Xiao Yan managed to avoid it.
Later with Xiao Yan's help, she obtained the Purple Crystal that left his Qi unstable because he had swallowed the Purple Amethyst Essence. She helped him stabilize his Qi and left him with a Qi Method, Dou Technique and her Sea Core Vest.
