While Feng Xun thought of Feng Wu as one of their own, Xuan Yi didn't. On the contrary, he made no effort to hide his disdain toward Feng Wu.
Feng Wu couldn't care less about Xuan Yi's enmity now. All she could think of was the Immortal Spiritual Fruit! The fruit that was essential to her pill that could enable her to cultivate again!
Feng Wu had been smirking inwardly before this, thinking, "I wouldn't follow you around even if you invited me to!" However, she had changed her mind.
With Jun Linyuan's intelligence and capability, together with the help of his friends, there was a 90% chance that he would obtain the fruit, if not 100%.
If she walked off like this, she might miss her only chance of getting an Immortal Spiritual Fruit in her lifetime. If that happened, she would remain this mediocre Feng Wu that was picked on and looked down upon.
Would she succumb to that fate? Never!
