Elder Universe responded plainly, "Won't you know what ore it is by using appraisal art?"
Ni Yinghong puffed out her cheeks and expressed, "Master, would we have come to find you if appraisal art was useful?"
"It isn't?"
"Yes, we couldn't see anything with the art," Ni Yinghong answered without any hesitation.
"That's impossible. Appraisal art is an art used to communicate with nature, so everything that belongs in this world is appraisable," Elder Universe commented while he looked at the peculiar stone. It was then that his eyes had flashes of radiance.
Ou Yangming's eyes lit up as he thought, 'This elder has a wonderful method indeed—he's able to replace the Appraisal Light with his look.'
Nonetheless, the wonderful method was probably the elder's ultimate art, hence Ou Yangming could not ask for the elder's advice no matter how greedy he was.
