Money!

The strong amber light wasn't something the old man had expected, as he was pretty sure what such a strong light signified. The light seemed to contain a mysterious warmth, as it covered the entirety of the small shop. The old man's eyes were practically shining at this point, he had never seen such a splendid mana crystal before! He gave Ark a peculiar look, "Can I take a closer look at it?"

Ark didn't really answer, he just nodded, and handed the mana crystal over. Even though he knew it was worth a lot of money, he wasn't afraid that the old man was going to try and steal it from him, he was confident in his strength. Unless the opponent had an overwhelming level advantage, he wasn't really scared. Naturally, he didn't believe that he was unparalleled amongst his level, he wasn't that arrogant after all. He had no idea how vast this world truly was, but he knew that it was certainly way bigger than earth, and there was always someone better out there.
