Shadow Aura

Godslayer began without hesitation.

Alex looked at the black book with his own eyes and slowly the blackness of the book was receding when viewed through his Demon Eyes.

Godslayer was absorbing every piece of Shadow aura that was on the book without leaving any behind, unintentionally collecting even the Shadow aura that was scattered in the abyss around him.

Of course, what was scattered could not be comparable to what was in the book itself. 

Alex waited on full alert in hope that no one else arrived close by. He had been following the young man named Zhan Lushin for who knew how long, and he was afraid that he accidentally got someone else to tail him, like he did the young man.

Thankfully, no one came in the multiple hours that it took for Godslayer to collect everything inside of the black book. At some point, Alex even saw the physical textures of the book with his own eyes after lighting up a small fire.
