Over the next few hours, Reilo stayed in the secret laboratory at Windsor Business Academy, patiently telling the four of them what he had seen after entering Curvature Space and sharing his ideas about the future development of spatial technology by scholars.
"The Space-Time Channels we can open now are far too tiny—or, to put it more accurately, the Space-Time Channels we can maintain at this stage are far too small. Until we learn how to open larger-scale Space-Time Force channels and keep them stable, the only thing we can send through such a minute channel is information encoded with a little Mental Power."
Reilo's words resonated deeply with the other four.
The Space-Time Channel, with a diameter of 0.001 centimeters, hadn't been opened by Windsor. She had extracted it from the pitch-black, ten-thousand-year-old ice at the bottom of the Death Abyss, following the experimental notes in the Frost Sorcerer's journal.
If they looked past appearances and examined the essence of how these Micro Space-Time Channels had formed and persisted, then analyzed the matter in depth—
The ten-thousand-year-old ice in the Death Abyss had appeared during a prehistoric ice age, before the ancient era of Starveil Land. An unknown civilization passing through the region had launched a cataclysmic extermination strike against the native civilization that then ruled Starveil Land, plunging the land into the Ice Age.
When Reilo had first ventured into the Death Abyss, he had also stumbled upon the frozen wreckage of a flying vessel.
The reason the Frost Sorcerer had survived for so long was not only that he had never left the Death Abyss and had lived in a half-hibernating state, encased in ice, but also that he had been affected by the unknown civilization's ice-box disaster weapon below.
It seemed, then, that the unknown civilization
