I read a novel recently that was really good, however, I forgot to put it in my reading list and now I do not remember the title.. It was about the female protagonist that had a small white dog (?) that can seek out rare treasures and see through ores?? Also one of the chapters was about fishing out rare fishes that are hard to get, however the female lead had her spring water from her ring space to attract them to her. And so she one the bet between the male leads friends.
