"Exchanging items, I wonder what you would like to exchange? I also happen to have some items in hand that could be used for an exchange," Han Li stroked his chin and said.
"The materials and medicinal pills this senior wishes to exchange are all right here. Although they may not be as rare as what the senior had just collected, they are also hard to find in the world, otherwise this Lightning Spirit Crystal would have been exchanged long ago. This is an excellent material for refining thunder attribute magic artifacts." The middle-aged cultivator was not surprised by Han Li's words and reminded him before handing over a jade slip that had already been prepared.
Han Li took the jade slip into his hand and examined it with his divine sense, noncommittally.
