It was an SSS-level difficulty mission for advanced games!
One could imagine how difficult the mission was, and high-difficulty missions meant high-level rewards!
Therefore, it was hard to tell whether the hidden effect of the curse was positive or negative.
In short, the curse effect did not reduce the value of the book. Instead, it made it even more popular!
However, most of the players in the Black Castle majored in psychic studies, so their learning ability in spatial science was limited. Furthermore, in recent years, the Black Castle's team had focused on Hila's main storyline mission, so they temporarily kept this book on spatial science.
In fact, many forces knew that the Black Castle possessed a spatial notebook, and many people had their own ideas about this book.
What a coincidence!
Fang Heng only needed an advanced skill book for spatial science?
It made people suspicious.
