Sunan could sense the thick energy particles contained within the book, indicating it was a magical item.
The other sphere was about the size of a fist, shining brilliantly, with countless star-like points inside, as beautiful as a starry sky.
If one concentrated on observing it, they would discover that those points were actually enchanted runes reduced by a multitude of times.
To Sunan's surprise, he could faintly sense that the energy contained within the sphere was flowing toward empty voids in a way he couldn't understand, seemingly connecting to the entire high tower.
A sense of realization arose in his heart.
This sphere might just be the energy source of this high tower, or perhaps the entire Fallen Star City!
Although he was very curious about the sphere, Sunan was more interested in checking the contents of another book at the moment.
Thinking this, he reached out toward the book, but in the next second, a low sigh suddenly echoed in his ear.
