บท 49: Sword Duel 3

<A 2-star knight has been defeated.>

<Quest {Beat the knights is advanced to the second state.>

"Huh?"

"Huh? Did you see it?"

"The sword looked like it was going to attack his shoulder. How come his neck was cut?"

Between all those sounds of surprise, I heard the system sound in my head, confirming the duel was over.

'Sword of Lightning, Trick of Light.'

It was a special type of movement that made use of the human eyes' way of perceiving things.

As you may already know, we are seeing the world around us with the reflected light coming to our eyes. 

Then, making use of that fact, if you can manipulate the lights around a person, you can make them perceive things in the way you want.

And this technique just does that, albeit I am not manipulating the lights firsthand.
