Some things just happen to coincide, I recall when I first arrived in Lingyu City, Rocky and Berg had mentioned Karina, but at that time I felt that it wasn't certain when I would see Karina again, so we didn't delve into conversation. Unexpectedly, just a few days had passed when they met again.
Although Rocky still didn't understand Karina very well, from the bits and pieces Berg let slip, he could tell that Karina, despite also being the City Lord of a small Sky City, was considerably stronger than the average City Lord, undoubtedly a formidable figure.
For such a person, given there was no conflict between them, Rocky naturally wanted to make acquaintance, so when he received Berg's invitation he didn't even return to the City Lord's Mansion but went directly to Lingyu City, of course, a large part of the reason he didn't return to the City Lord's Mansion was that he didn't want to see Orton, that old man was just too difficult to deal with.
