Wisps for Sure
Naturally, Feifei and Krune could have left anytime they wanted. With the difference in cultivation, there wasn't really anyone who could hold them back. Still, Krune stayed there for longer so that he could talk more with the new Wisps. Feifei understood that Krune regarded it with importance. That's why she stayed there and helped him with it as well.
It wasn't before a few hours and thousands of questions later that Krune and Feifei finally left the Wisp Registration Office. They used their understanding of the Space Laws to simply teleport away. When they reappeared, they were already several kilometers away.
"Sorry, Feifei. I held us there for way longer than I should have."
Feifei tilted her head in confusion before shaking it as she replied.
"What you are talking about? Talking with that many curious wisps, especially the ones who turned females, was quite funny. I didn't mind it at all."
