Xu Qi 'an and Dongfang Wanrong had some interactions. Dongfang Wanrong had once sealed Li Linsu's cultivation and kept her by her side for half a year. Later, Li Linsu was rescued by Xu Qi 'an. After the great calamity descended, Dongfang Wanrong followed the instructions of the Great Sorcerer Salen Agu and went to Jingshan City to witness Xu Qi 'an severely injuring the Great Sorcerer. In the end, she and the other Sorcerers submitted to the peerless Martial God Xu Qi' an.

Xu Que and Xuanyuan Wanrong weren't together. In the novel The Strongest Anti-Trickery System, Xu Que had traveled to the Fire Nation of the Five Elements Mountain and became the recently killed Prince Consort Xu Que. He embarked on the path of revenge and didn't get together with Xuanyuan Wanrong. Although Xu Que had saved Xuanyuan Wanrong, the novel didn't describe the development of their relationship. It also didn't describe how they left the Five Elements Mountain and the Fire Nation together or how they were together. Therefore, it was impossible to determine the outcome of their relationship.
