"Hoh so you travelled through the yeti infested valley to get here, no wonder you got so many crystals and materials." Ryan looked Frost up and down finding that there wasn't a single hair out of place on his handsome face, neither were there tears in his clothes. His initial reaction would be to claim bullshit. Frost was so young and alone plus he didn't give off a super threatening aura like those at B-rank or higher. Ryan was based in the Glacial mountains and worked in more than just this Beta camp, occasionally he was also stationed in the inner regions and his own strength was equivalent to D-rank, even with his current frame. To be an able merchant in such a vicious climate one needed strength, especially when starting out.
Ryan had come across more than a dozen people at B-rank and even those higher, Frost did not give him such a feeling, but he also didn't seem like the type to lie plus he had the items in his spatial ring and all of them were rather fresh.
