Rex sweated a little.
He was worried.
Not only because Kei Xun was a lot stronger than him—or the fact that she was not even among the strongest, but also because this whole entire situation was new for him. In the Mortal Realm, whenever two entities at the height of power met, it would always end in a fight.
Or at least, that was certain during their very first exchange.
It has always been a battle to the death for him.
So the fact that Kei Xun was doing this was unsettling, and she did it with passion, too.
"No…?" Kei Xun interrupted, taking Rex's silence as defiance instead of confusion or disbelief. "Do you still not get it? Was it because you're weakened? Not in full power—because of your little scuffle with that favored Voidal Knight? Okay, let's fix that."
Swoosh!
Overbearingly, Kei Xun channeled her life energy and shot it into Rex's body.
Upon impact, there was no pain.
Rex could feel her power spread through him instead, reaching every corner of his body.
