The Book of All-Knowing is known as the most powerful Golden Marvel.
It holds all the information of the cosmos, a capability not even possessed by the divine.
Many powerhouses consider the Book of All-Knowing a divine artifact, and a top-tier one at that.
However, attributing divine status to it doesn't quite fit the characteristics of the Book of All-Knowing. This notion has always been widely debated.
Regardless, the Book of All-Knowing is exceptionally powerful. Its power even goes beyond human comprehension.
In the previous era, only at the very end did the human powerhouses get hold of the Book of All-Knowing. Only then did they unravel a few crucial issues.
Unfortunately, humanity had already missed the best opportunity. Even with the Book of All-Knowing, they were powerless to retaliate.
The principle of the Book of All-Knowing is fair trade. To get answers, one must pay an equivalent price.
