Inside the Wahuang Heaven, Goddess Nvywa learned about Zhenyuanzi and thought about the person who had listened to the teachings inside the Zixiao Palace at the same time as her.
She had originally wanted to send someone to congratulate him. However, thinking about how the Demon Tribe, had had something to do with what happened to Hongyun, she could only give up.
At any rate, Zhenyuanzi establishing the Earth Immortal's Residence didn't have anything to do with the Demon Tribe. It wouldn't matter if she didn't go.
As for Two Sages of the West, their preaching was hindered by Zhenyuanzi's Way of Earth Immortal. Even Zhunti, as someone who really loved to exploit everything to his advantage,
didn't have any interest in going, even if the situation ought to be very lively. Besides, none of the other Sages had gone. If he went by himself, it would indeed be a bit
embarrassing. Thus, he simply sent his disciple to go and congratulate him as a formality.
