Silently, Li Yao focused his spiritual energy on his eyes and observed the workers in the Great Iron Plants carefully by maximizing his eyesight.
When observed from so far away, the workers who were busy working on the furnaces, the tubes, and the iron scaffolds were like black and brown ants.
Most of them had covered themselves tightly in gray capes and were wearing simple protective respirators and eyepatches. Their skin that was exposed to the air, however, had been smeared into brown and black because of the dust and the pollutants. Also, because of the protective earplugs that they were wearing, they were somewhat sluggish and inert, like a bunch of mechanical reptiles that were not fully-wound or a group of lifeless zombies.
