Those shadows were nothing else but sand holes.
Although Huo Sining didn't understand much, it was clear that those densely packed sand holes weren't just on the surface; they had already penetrated through the outer layer into the inner flesh of the jade.
No one could estimate how far those sand holes had spread. If the entire piece of jadeite was riddled with sand holes, then even if a Glass-Type Imperial Green was cut from this rough, it would be worthless.
However, such a large rough, if the sand holes only penetrated, say, three-quarters of it, a rough weighing over a hundred jin could yield more than ten kilograms of jadeite, which was a significant temptation for gamblers.
Huo Sining had seen gambling on cracks and sand holes online, and the rough she had purchased that Zhou Zhen had deemed worthless was a bet on black moss. Although her method was somewhat cheating, it was akin to a clever workaround.
