Bab 248: Sixth Rank

"I'm going to make your powers mine!", Rex shouted in delight.

Hearing this, Devo chuckles slowly as if he's underestimating Rex, "No humans in the past 10,000 years have managed to assimilate with me, What makes you think you're able to?"

Devo looks down on Rex while crossing his arms in front of him,

The look on his face is that of a mocking look, his lightning eyes blitz mockingly as if he's saying to Rex to back down.

But unknown to Devo, Rex is not a human.

NGIING!!

14 black dots appeared all over Rex's body as he activates his black lightning, 

The media all over Rex's body glows fiercely as it emits a horrifying amount of mana, the air started to tremble as the condensed place got filled with mana to the brim.

CRACK!

The barrier from the spikes started cracking, it can't hold the clashes between Rex and Devo.
