Li Hongyun directed the craftsmen, mixing iron sand with limestone powder and filling the furnace layer by layer with charcoal. Once it was filled, they ignited the fire and had the craftsmen fan the flames relentlessly.
During this process, Li Hongyun discovered that these craftsmen truly were mere tools.
Whatever he arranged for the craftsmen to do, they carried out without deviation. However, for tasks Li Hongyun did not specify, they would rather stand idly by than take initiative.
For example, during the smelting process, a large amount of impurities would flow out from the bottom of the furnace.
These impurities were smelted slag that needed to be cleared regularly to prevent blockages.
Li Hongyun had quite a difficult time getting all the craftsmen organized clearly, while he himself cautiously sped up or paused the flow of time to check the state of the iron ore smelting.
The game's unlimited supply of high-quality iron sand and charcoal was already very accommodating.
