"Taiyi Tungsten Crystal? When did I mention that? What's its use?"
The young man in the blue shirt asked curiously.
"Taiyi Tungsten Crystal is a second grade Immortal Material, commonly used to refine middle grade Immortal Artifacts like the Flying Needle. Tell you what! Five hundred Immortal Yuan Stones, that's not a low price."
Ye Yunqing said with a smile.
"Six hundred. Second grade Immortal Materials are not that cheap, especially those used for refining Flying Needle-type Immortal Artifacts."
The young man in the blue shirt bargained.
"Taoist Friend Wang, this piece of Taiyi Tungsten Crystal is a bit small, five hundred and fifty Immortal Yuan Stones."
Ye Yunqing replied.
"Six hundred and seventy, can't go any lower."
The young man in the blue shirt said.
Ye Yunqing hesitated for a moment, examined the black crystal stone carefully, confirmed it was Taiyi Tungsten Crystal, then relaxed and nodded: "Deal."
