If there's jade inside, the jade and the stone are separate, and the sound of tapping the stone is hollow.
But because the jade in this kind of stone is very small, the difference in the sound from the stone is very subtle, and only people with excellent hearing can discern it.
According to the records in "Bian He's Jade Collection," only a person like Yang Chen, with extraordinary qualities, can learn this skill. Ordinary people simply can't manage it.
The second stone that Yang Chen selected needed to be tapped to confirm whether there was green inside.
"Thump, thump, thump..."
Yang Chen gently tapped different spots on the surface of the stone, carefully distinguishing the differences in sound.
After tapping around in a circle, Yang Chen placed the stone into the basket.
Xiaojing quickly asked, "Brother Yang, you're an expert, huh? You look quite professional."
Yang Chen chuckled and said, "I'm just taking a wild guess. Can I go upstairs now?"
