"The material from "Ka Chang" is generally good, little brother, although the piece in your hand isn't big, its appearance seems promising. If luck is on your side, you might end up with a sizable chunk of nice jadeite."
While Lin Yi was communicating with the system in his mind, Zhuang Yan next to him suddenly handed over a small flashlight and started explaining to Lin Yi.
Once he finished speaking, Lin Yi also started laughing:
"Haha, material from "Ka Chang" is usually pretty good. The outer skin is delicate, smooth with a pale green hue, often humorously likened to frog skin. Under the flashlight, it usually shows up well, often turning out to be 'glutinous' or 'icy' jadeite.
Looking at this piece, it should produce a 'glutinous' jadeite, but the size might not be very big, I estimate around 15%-20%."
Mimicking the actions of others around him, he pretended to scan the rough stone with the flashlight and then shared the system's assessment in his mind.
