Maria instantly hit it off with her new team, but that's not surprising. Maria is charismatic, attractive, strong, kind, and enjoyable to be around. Even in this world where people will kill their own mothers for cultivation resources, it's hard not to like Maria.
Naturally, the guys in the group had no issues with her other than her cultivation. However, this was also a good thing after they thought about it some more. They'd be able to show off their manly and righteous side if they were to protect Maria from danger. Then who knows, Maria might start taking an interest in one of them…
The women weren't annoyed by Maria's presence either. In terms of beauty, although they might not be quite as radiant as Maria, they are still beauties in their own right. They are also stronger, have better gear, possibly higher status, and are richer than Maria. Why would they be jealous?
