Ye Chen was interested when he saw the bustling crowd and the constantly hawking merchants. When he passed by a blacksmith shop, he casually chose a dagger and thought that it was not bad. When they said that they wanted ten crystals, Ye Chen was stunned for a moment but he quickly understood.
It was just that he had just come out of the Small World inside. How could he not have seen any crystals before? However, he had quite a number of medicinal herbs and materials with him. He could exchange them or buy them.
Looking at the white crystal that was given to him when he was buying things, Ye Chen understood that the crystal was like the currency on Earth. Hence, if he wanted to survive here, he had to get the crystal first. Otherwise, he could not stay here.
