To be able to obtain such detailed information from Ann had already exceeded his expectations.
There was a lot of content recorded, even the dragon race inherited memory was not as detailed as this. Garen planned to bring back more goodies the next time he goes over.
Heavens, the Main Plane, and the Abyss.
The names of the three places flashed into his mind. This was the most fundamental core of this universe.
It was unknown how big exactly was the Main Substance Plane, it was like a gigantic sphere. He recalled the scene he saw when he just arrived, everything on the plane was yellow-brown. It was unclear what those cotton wool-like objects were, just that they were attached to the surface of the Main Substance Plane.
"Too bad this book's not about the plane's geography…" He shook his head and closed the book completely.
