Yao Xun's body slightly straightened, and two glimmers flashed in his eyes, but in the next moment, he returned to his original lazy demeanor.
The two were less than three feet apart, and Zuo Feng clearly observed the changes in Yao Xun. After a moment of hesitation, Zuo Feng casually asked, "Elder Yao, what do you think of this black stone?"
Yao Xun remained in his lazy posture, but his eyes stayed fixed on the black stone. After a brief contemplation, he said, "In my experience, this is neither any kind of mineral nor some rare medicinal material."
If others heard Yao Xun's words, they might scoff, since earlier Li Ru had said the same thing during the introduction. However, Zuo Feng had a different opinion. After hearing Yao Xun's words, he couldn't help but take another look at the black stone.
