Fang Zhou was not interested in watching Gu Caiwei deal with her enemies and directly lifted off from his original spot, heading towards the Dragon Elephant Sect.
Aya didn't follow him since she had accumulated quite a bit of energy through massive food consumption, which could only be used for daily body maintenance and didn't really help restore her combat strength.
The gourd Fang Zhou carried already contained backups of Elder Yan Fu's purified Soul Fire, which Aya could take to restore some of her combat power.
For now, dealing with the Dragon Elephant Sect didn't require her appearance.
According to Gu Caiwei, the Dragon Elephant Sect was in charge of trade and intelligence, and it didn't have any particularly powerful experts within. The sect master was a high-level member of the True Mother God Sect, serving in a part-time role and wasn't usually present in the sect, with only a few Innate elders stationed for guard.
