"An extra-dimensional space expanded by five centimeters?"
A hint of undisguised disappointment crept into Reilo's murmured words.
Although the Human Academic Circle was only in the early, tentative stages of researching Curvature Space technology, and had even been forced to fight the Superhumans of the Pangula Highlands to advance its knowledge and civilization, then send Reilo to the Underground World to seek clues, in Reilo's eyes, the technology to expand an extra-dimensional space by five centimeters was hardly worth mentioning.
At first, Reilo had assumed that the Underground World's so-called victory, hidden within five centimeters of space, referred to the technology of stabilizing and embedding a five-centimeter spacetime rift.
After all, although the Human Academic Circle had yet to master the technology to expand an extra-dimensional space by a mere five centimeters, by the Academic World's standards, the Space Box developed by the Holy See of Aurora's Central Lands and the sacred relic of the Sky Palace left behind from ancient times were both already far larger than five centimeters.
So, to Reilo, this technology didn't seem particularly remarkable.
But the opposite was true.
If they could obtain the technology to stabilize and embed a five-centimeter spacetime rift, the Academic World would be capable of so much more. At the very least, it would have the basic technology needed to communicate across the entire Starveil Land.
"You seem disappointed."
The Observer had keenly noticed Reilo's mood.
"I suppose I am."
Reilo admitted it.
"Oh?"
The Observer looked surprised. "Does that mean your Human Academic Circle has already mastered more advanced extra-dimensional space expansion technology? If so, you already have basic defenses against the Superhumans' spacetime-breaching explosive power. Then did you come here to obtain the technology for embedding spacetime rifts into the real world? Unfortunately, even if the Sleeper were
