"Tree group messages?" A sense of puzzlement flashed in Sanders' eyes; he did not understand Angel's meaning.
Instead of immediately answering, Angel took Sanders back to the Wilderness of Dreams.
The place they entered in the Wilderness of Dreams was near a towering circular bookshelf. Sanders glanced around and quickly recognized that this was the second floor of the library in Originheart City, specifically the Mathematical Pavilion.
Sanders had visited this library before and was quite familiar with its layout. The knowledge housed in the Mathematical Pavilion required a certain level of foundation, so it was usually sparsely populated. However, in Sanders' personal view, this pavilion was actually the most valuable section of the entire library.
From what Sanders knew, this pavilion was entirely created by Jon, and most of the books here were also authored by Jon.
