Aura Of Slaughter
After nearly destroying his house, Klaus decided to buy a much bigger one. This time, he made sure some of the training rooms were far sturdier than the previous one. He didn't want it crumbling the next time he unleashed a powerful energy.
Today was one of those days. After returning from his five uncles, Klaus decided to enter seclusion to awaken his slaughter Aura.
As he entered the training room, he sealed the door and made sure his family knew not to disturb him until he came out.
He retrieved the Mad Berserker Red Tiger Core, and immediately, a bloodthirsty aura filled the room, making Klaus's blood boil.
"This is one dangerous core. I wonder how powerful the monster this came from was," Klaus muttered.
"Don't even think about it. With your current strength, it would crush you with just its aura," the senior said, his tone slightly amused, as if he'd just heard the joke of the century.
