Yu Sheng still had many more questions in mind. He could also sense that Baili Qing was hiding some more crucial secrets—for example, how exactly the enormous "anchor" that was Boundary City kept the entire Crossroads at L-0 depth, and what the anchor's operating mechanism and construction process were. For example, exactly how would excessively rapid technological development affect the anchor's stability, and what principles were involved? And before Boundary City's "anchor" took shape, what state had the Crossroads been in...
After all, the city had not appeared out of thin air. It must have gone through a process of being established and perfected. From the details Baili Qing had let slip, the Crossroads had likely once truly gone through a chaotic period whose average depth far exceeded L-0. Could there have been human natives in the Crossroads back then? And had those natives found a way to use the "anchor" to pull their homeland up from the depths to L-0?
It sounded inconceivable, because one universally known fact was that rational races could survive long-term only in places at depth L-0. If the Crossroads had truly gone through a chaotic period at a depth beyond zero level, then it would have been impossible for large numbers of humans to survive here.
He hesitated for a moment, but decided to ask anyway.
In response to his question, however, Baili Qing merely shook her head.
"Very little of the history before Boundary City was established has been recorded. Even the history of some time after Boundary City's establishment seems extremely chaotic. It seems that we rebuilt this place from a ruin, but why it became a ruin in the first place remains a mystery. Perhaps it was just as many scholars have speculated: that period of history 'got stuck' at the
