Outside Marsel City, a massive mining unit descended from the sky, quickly deploying mining robots and refining equipment on this frozen land.
After numerous upgrades, the mining robots now resemble spiders; their mechanical arms are agile and powerful, wielding constantly rotating excavating heads that emit piercing roaring sounds.
These robots are stripping away layers of ice and permafrost from the surface of the mine, revealing the deeply buried ore beds beneath.
Then, they began their destructive excavation, with gigantic drills penetrating the rock layers, tearing the ore from the earth.
The ore wasn't transported directly but sent to the refining equipment nearby for preliminary smelting instead.
The refining equipment resembles a small factory, with its internal high-temperature furnace heating the ore, separating out impurities, and finally making crude metal ingots.
