Li Xing waved the Wind Crystal Stone in front of the absent-minded Ye Qingting until his eyes focused, then asked, "High-tier Crystal Stone, do you want to exchange it?"
The higher the tier of the Crystal Stone, the more Elemental Power it extracts, making it more valuable. In emergencies, high-tier Crystal Stones can substitute for Energy Stones to urgently replenish Elemental Power. So, high-tier Elemental Spirits are willing to exchange for high-tier Crystal Stones. But Li Xing went the opposite way; the lower the tier of Crystal Stone, the more Chaotic Power it contains, which is more useful to her.
"Exchange!" Ye Qingting quickly expressed his stance.
"I want low-tier Crystal Stones."
Ye Qingting nodded, "Okay, the size and quality of this Crystal Stone are better than the usual high-tier ones. I'll exchange it for you at a rate of one to a thousand, but you'll have to wait until I get back."
