The Myriad Miles Library was as Cao Cuifen had described; an independent dimensional space immediately upon entering the doors. The feeling could be described as utterly seamless, almost unnoticeable, unlike other spatial relocations or entry points. When Wei Wuyin looked back after entering, the entrance reflected the outside area, and one could even see various figures walking to and fro.
If one had said this wasn't a separate dimensional space and the library was simply a typical building with a standard doorway, both inside and outside occupying a single space, Wei Wuyin could've been fooled in the beginning. However, Kratos would've immediately shattered the lie. It was raging with excitement, roaring softly with short bursts of invigorated roars. It resembled a tourist's exclamation upon experiencing something new.
