"Haha, how would I know? I... I was just saying, I didn't expect you to actually have one, did you?"
Tang Feng immediately laughed it off, he would never admit that he had scanned it with the system.
To be honest, when the system reminded him that Ma Qizhi had a piece of dragon jade on him, he too was startled.
He had not known about the existence of dragon stones before.
It was through the introduction of the system that he learned how rare dragon stone jade was.
So when Ma Qizhi challenged him, he tried to propose using dragon stone jade as the wager, not expecting such a big reaction from the other party.
Ma Qizhi stared at him intently, unable to discern whether he was telling the truth or lying.
He couldn't be bothered to think about these things and instead scoffed, "Heh, you want me to bet with dragon stone jade, what are you going to bet with?"
That question really stumped Tang Feng.
