Chapter 391: Chapter 391: The Cloak

"As soon as the shine of the crystal ball becomes dim, stop touching it and keep it back in the pockets," the scientist exclaimed.

'That's true. The decay helps me steal life energy, sometimes even working on attacks. When I'm out of energy, I can absorb from these. It's certainly useful.' Lucifer thought, glancing at the crystal balls in his hand. 

'But how did this guy know that my decay can steal energy?' A frown also engulfed his face. 

"What do you mean absorb the energy? How can I do it?" Lucifer asked, acting ignorant. 

"You don't have to hide it. I'm not the only one that managed to guess it." the white-haired man smiled. "In any case, it's just how your power works. It's not the limitation of your decay. So there's no reason to keep it hidden either."
