Stellar Well

Without a doubt, the enormous deep well at the very center of the model was the Escape Tower.

An area the Salvation Sect had yet to fully explore was completely laid out on this map. Though it was only a rough outline, it was already invaluable intelligence to them.

"Wait..." Xia Fan's eyes widened slightly. Wasn't this Escape Tower far too deep? If those interwoven layers of tracks were considered a dense canopy, then it was like an immense tree trunk, holding the entire canopy above its head! Judging by their proportions, didn't that mean the Escape Tower was at least one or two thousand kilometers deep?

What kind of concept was that?

The Moon's entire diameter was only a little over three thousand kilometers!

Though the Moon looked small, its core temperature could still reach over a thousand degrees. Coupled with immense pressure, thirty percent of its core material remained molten. Building a permanent structure here would be no easier than constructing an elevator into space.

Moreover, he noticed straight cross-sectional marks around the tower's base—on architectural drawings, those usually indicated omissions or segmented portions.

It was hard to imagine such a colossal project had been built solely for escape.

The more Xia Fan looked, the more horrified he became.

Their layout was highly three-dimensional as well. Aside from the special train they had taken, there were at least three more track levels below, and the deepest routes could reach the middle section of the Escape Tower.

Second, the Escape Tower had over a hundred floors of residential areas. If it was merely a platform for launching spacecraft, why
