Night fell, and on the previously pristine snowy surface, bulges began to appear one after another, and then one skeleton after another crawled out from beneath the snow.
Unlike the initial skeletons, which needed time to acclimate after emerging, the skeletons now attacked their kin without hesitation as soon as they surfaced.
Thanks to the new materials, the military drones' endurance had long been sufficient for all-night filming, so those at Command Headquarters intently watched the videos the entire night.
As dawn broke, the skeletons that were furiously fighting gradually receded back into the snow, and the chaotic mess left from the battle was covered up by the light snowfall, leaving no trace behind.
