As they made their way toward the top floor of the Towering Skyscraper, Saine and the others discovered and collected quite a few Ai Youlan Butterfly Civilization technologies and materials.
Some items, even without energy or law fluctuations, were judged by Saine and the others to possess immense research value.
They truly wished they could pack up the entire Towering Skyscraper and take it away.
From another perspective, if the Wizard Civilization could win the war for this subspace and the Surrounding Starfield, these Ai Youlan Butterfly Civilization Ruins would indeed fall into their hands.
As they continued upward, Saine and the others traveled through special passageways along the edges of the skyscraper.
Geli said, "Ai Youlan Butterfly Civilization lifeforms seem to have liked keeping special escape routes in reserve."
When the physically frail Ai Youlan Butterfly Civilization lifeforms had traveled to the upper floors back then, they certainly had not taken the same laborious and thankless route as Saine and the others.
Yet these special escape routes, which possessed little technological sophistication, had now become some of the few usable paths for Saine and the others to travel through.
Besides these special escape routes, Geli, who had conducted deep research into the Ai Youlan Butterfly Civilization Ruins, had also opened up several new routes through many obscure corners of the skyscraper.
"This is a ventilation duct connecting the inside and outside of the skyscraper. The Ai Youlan Butterfly Civilization lifeforms seem to have established another purification system here, so we probably won't be able to reach the very top floor. At most, we can only make it halfway."
"It is indeed a little cramped inside, but that's nothing to us." Geli pointed at the pitch-black, deep passageway, which was less than half a cubic meter in size.
Saine did
