*BOOM!*
Just before Greg could have warned the others, the books from the sky opened, and with a blinding light several explosions broke out.
"Damn it!"
Not having a choice at all, Greg grabbed Emma and Laura on his side, and by using his darkness element, he vanished into his own shadow and appeared somewhere safe again.
"What about the others?", asked Emma a bit worriedly as she looked toward the explosions in the distance.
Naturally, she was not stupid at all, and she knew also that those books were extremely abnormal.
Each of those had the presence of top God-ranked fighters, so trying to defend against them with their current strength would have been a foolish act.
Knowing this fact also, Greg wanted to activate his darkness element again, but as he did, something terrifying happened.
