And in the gorge, gigantic Spider Mechas, modified from the Spider Main Battle Mechas into engineering machines, were deeply drilling and anchoring themselves into the rocky terrain with their long spider legs. They were excavating the earth, and when encountering massive rocks, they would strike continuously with their spider legs and shatter them with the installed heavy-duty drills and hammers.
In the middle part of the Spider Mecha, where machine guns used to be mounted, hydraulic mechanical arms had been installed instead.
Two huge buckets scooped up large swathes of soil and rocks into the massive bin on their backs, and then these materials were conveyed to the surface via a gigantic conveyor belt.
To handle the tremendous volume of transport, even the conveyor belt had been modified so that tons of soil and rocks could be easily transported from the gorge to the ground dozens of meters above, to be then carried away by various excavators and trucks.
