Of course, it wasn't possible to wash all the rough stones with water, so Huo Sining exchanged a glance with Bai Yishan, silently communicating for a moment before quickly establishing their division of labor.
Recently, Bai Yishan had been intensively studying knowledge about stone gambling with Su Jinyuan, and at least she knew how to judge the source and type of jade by the appearance of the rough stone's skin.
Since all these rough stones were waste, they decided to pick out the ones from the old mine that were most likely to contain jadeite.
Thus, Bai Yishan was responsible for the preliminary selection, sending the rough stones she picked to Huo Sining, who would then appraise them using the Water-Repelling Pearl.
The recycling station had an innumerable number of rough stones; Huo Si's method of selecting them might have seemed foolish, but to find overlooked treasures, Huo Sining had no choice but to proceed this way.
