With a sense of resignation, Chen Yu heaved a sigh. He didn't want to participate in this kind of gathering, but he couldn't stop it; he had no choice but to turn around and leave the venue.
"Mr. Chen, please wait!"
Fox suddenly shouted and, holding two gemstones, hurriedly approached Chen Yu.
"Mr. Chen, you are an expert in gemstone appraisal. I have two gemstones here, one is real and one is fake. Can you tell any differences?"
Chen Yu lifted his finger, pointing to the one on the left.
"Actually, synthetic gemstones still have many flaws. If Mr. Fox plans to put such gemstones into the market in large quantities, I'm afraid there will be problems."
Fox didn't care about that. He just chuckled twice and returned to the podium.
