The chubby Shopkeeper Jiang said with a fake smile, "Mr. Wang, I inquired thoroughly before coming here. Your Wang Family has long mastered the technology of mass producing refined coal and refined iron. Now, the entire Longzuo Yan Family mines coal and produces refined coal and refined iron in their own territories. The cost of one jin of refined iron has already been reduced to two or three large coppers by you."
"The material and transportation costs of one refined iron pot combined are at most thirty to forty large coppers, yet you charge me one Qian Gold and fifty large coppers! Isn't that too dark? Are you looking down on our Jiang Family, looking down on Saint Master Jiang?"
