"Once a sister, always a sister!"
Qi Yuan still very much values ethical and moral principles.
The moment he spotted Ruan Yixi, he decided she was his wife.
That's why he always refers to her as his wife.
Given that the Ice Queen is much older than him, he of course needs to address her accordingly.
"I'm still young and beautiful, yet you people keep making me sound old!" the Ice Queen exclaimed through gritted teeth.
At first, when she was at the pinnacle of cultivation, she never put on airs in the group. Neither did she act inferior in front of Qi Yuan.
"Our Ice Queen is as beautiful as a gazelle in her prime!" the Rogue Immortal flattered just in time.
Now the Rogue Immortal has resigned himself to his fate. His own talent isn't up to scratch and his buddy, the Origin Emperor, who used to huddle with him for warmth in the group, has become a top dog. He is left as the only real newbie in the group.
