Flying among the sky-touching trees and undulating mountain ranges, the fighter aircraft plunged down after crossing several ten-thousand-meter peaks, passing through an invisible barrier and instantly becoming enveloped in brilliant light.
Below, the valley was brightly lit, and amidst the thunderous vibrations, more than a dozen machines resembling crusher machines, several tens of meters in size, operated continuously, breaking apart rocks and carving through mountains.
In front of the massive rotating gears of those crusher machines, hard rocks were continually shattered, almost leveling an entire mountain range to the ground amid billowing smoke and dust.
Meanwhile, in the nearby mineral processing factory, many staff were busy separating the rich energy crystals from the ore and collecting them.
