Klaus never expected to be handed a powerful technique like the one his father-in-law had given him.
First of all, he never expected people of Earth to have such an advanced technique that, even in his many lives, he had yet to truly find a sword aura technique as impressive as this one.
Sword cultivation was something Klaus knew he had done in his third incarnation as the Asura god.
So, while he didn't know how that life went, he had a deep-seated feeling within him that this technique in his hand was the real deal.
He could already see the potential in the skill, and as someone who valued power, he was genuinely happy to have received it.
The only question on his mind now was how any of this was possible.
Walking the sword path for as long as he had known depended on many things.
There was the concept of understanding how to use the sword without cutting oneself. That part sounded easy, but it was the foundation of every swordsman.
