The machines worked like real monsters in front of Arthur's eyes. They kept digging the dirt and exposing the depth of Earth non-stop.
With time, the ore layer started to come clear to their eyes. The Gruben ore run deeply in thick veins from the mountain to the depth of the ground.
"So it's like what Sara said," Arthur muttered while watching Agnus directing workers to expose more of the ore without scratching its surface.
He didn't want to lose anything if possible. So he tried to find the edges of these veins to extract ores from them with the least losses.
"It's starting!" After around an hour, they finally found the edge of the veins. It wasn't them who discovered it, but the distant workers digging the Earth to lay down the foundations of the city.
"The veins are so thick to even reach there! That's awesome!" Arthur flew there and examined the veins exposed. He felt great happiness while assessing the grand scale of this hidden mine.
