Chu Yi nodded slightly, "Yes, could you please tell me the price of these high-grade Yuan Stones?"

The vendor raised a finger, pointing to a crystal-clear high-grade Yuan Stone, "This is the finest high-grade Yuan Stone, priced at exactly thirty ordinary Yuan Stones."

Hearing this price, Mu Qingyin couldn't help but gasp.

She knew that ordinary cultivators had to pay a huge price to gather that many ordinary Yuan Stones, let alone high-grade ones.
