Elder Li and So Rou was also stunned after seeing the excited face of Weapon Hall Master Mu Dong. Mu Dong was a 6th level weapon refiner who was famous in the Long Imperial Dynasty. He was now impressed by the weapon refining knowledge of Feng Yun. But soon they became dumb folded when conversion Feng Yun and Mu Dong started the opposite route. Now it didn't look like Elder Mu talking to a junior disciple, but he was conversing like a fellow refiner.
Feng Yun has knowledge of the 9th level of weapon refiner, how could a sixth level refiner able to cope with it. But Feng Yun didn't reveal too much, fearing that the weapon hall master would be suspicious.
"Hahaha, Feng Yun, you are truly a prodigy refiner." Weapon Hall Master laughed loudly and said.
"Weapon Hall Master, you are overpraising me." Feng Yun said with a grin.
Two old men chatted with Feng Yun for a while, then got up and left.
