After leaving the Fire Phoenix Immortal Inheritance's True Ring, Davis, Evelynn, Isabella, and Mira entered the Nine-Treasured Immortal Ordeal Palace. Eldia was also with him, having entered his soul sea.
To her, the phoenix souls were not that effective since she wasn't off the fire attribute. If anyone would have a snack at it, then they guessed that it must be Starcy or the others who trained in fire-attribute to obtain better results.
As for the immortal crystals, she could smell that there was even more of a better treat inches away from the life ring on Davis that was leaking heavenly undulations that were only sensitive to her.
As for Nadia, she stayed to get some treats from Shirley, obviously targeting the Low-Level Immortal Crystal Vein Fragments that would allow her to continue to grow faster.
