The Only Aura User In Magic World

Whoa! They make it look so easy to kill fifty people!

Celestine sunk most of them to the ground, and Veronica took care of the rest who managed to dodge.

There's only one man left. I don't know why but it seems like he's being spared.

Then the two looked at the window where Kayla is. Seeing Kayla shook her head, Veronica killed the man.

I guess Kayla needed to try something, but she doesn't think that the man they spared is good enough for it. That's why she shook her head and tell the two to kill him.

All of the bad guys aiming for the girl have died. Except for the one watching them from afar.

He watched the event unfold in shock. Never in his wildest dream that whatever they are planning to be destroyed in a matter of seconds. Leaving none of the thugs alive.
