Therefore, Shi Yin could interact with Jinrong in the capacity of a craftsman and was respected by Jinrong.
Inspired by new things not belonging to this era, the original staff of the Mechanical Workshop and the craftsmen continuously brought in by Cheng Dahui were all in high spirits, devoting all their time to the manufacture of the blast furnace, apart from necessary meals and rest.
With repeated experiments and improvements, the production progress of the blast furnace was swift.
