The newly resurrected Heavenly Emperor appeared just as she did in Slow-Witted Song and Cheng Lin's memories. After her resurrection, her goal was to rebuild the ancient Heavenly City and discover her own path.
However, lately, the actions of the Celestial Thearch had taken a peculiar turn. She seemed to possess a vast knowledge and was no longer willing to adhere to the Heavenly Dao. She desired freedom.
Consequently, Slow-Witted Song decided to accompany Fairy Cheng Lin on a journey to find the Celestial Thearch and engage in a conversation with her.
The reason for bringing Fairy Cheng Lin along was Slow-Witted Song's concern that he might be at a disadvantage during this conversation and that there was a risk of violence. By having Cheng Lin accompany him, they could potentially overpower the Celestial Thearch if physical persuasion became necessary.
