No matter which side's units were used, the actual perception was always about the same. Twelve meters was roughly the height of four Sergeant Major Le Zuos standing on one another's shoulders. However it was calculated, that was nowhere near a safe distance.
Judging from the present situation, that long tail, only about as thick as a little finger, was moving with remarkable activity. Even through the permafrost stratum, hard as iron and stone, it was piercing forward at two meters per second.
That was already an ordinary person's walking speed.
The Soil Layer Voyager carrying Ronan and the others was hidden in a cavity not far beneath it, one filled with Frozen Nitrogen. Half of the cavity had formed naturally, while the other half had been excavated later. It also included part of the work area.
In short, it was a place that could not withstand close scrutiny.
The Electric Spine Serpent above only needed to adjust its direction slightly, and that slender tail, stretching nearly a hundred meters, would probe into the cavity. With another twitch, it would strike the Mimetic Armor externally mounted on the Soil Layer Voyager. By then, the tail appearing above their heads would most likely not be the only one.
Even though the tail now seemed to be trending upward again, who knew where it would turn next?
