Luo Ning had delved deeply into how to find jade within rough stones. Besides examining the outer surface of the stones, she could also sense the energy within them.
If there was energy in the rough stone, it definitely contained jade; if not, it was empty.
The denser the energy, the better the quality of the jade contained within.
However, Luo Ning didn't write down all the jades she was interested in but chose only one-fifth, mainly those with high energy.
The better the quality of the jade, the better it would be for carving and nurturing auspicious magic artifacts, and for setting up Arrays as well.
After all, with so many people attending the public auction, if she were to select all the jade, it would be a wasted trip for the others.
Of course, apart from the rough stones with jade, she deliberately picked some waste material to include as well.
Otherwise, a hundred percent success rate in revealing jade would be too ostentatious.
