Defending

Ning looked at the man's two daggers that were about 15 centimeters long and glinted yellow in the firelight.

They were so sharp and smooth that Ning could nearly see the reflection of everything around him. 

Suddenly, the daggers started moving. They no longer looked so sharp or smooth and instead looked overly fuzzy. 

'Is it moving?' Ning thought. That was what it seemed like. Like a fly's wing moving up and down, the dagger seemed to be moving up and down very rapidly. The assassin was making it vibrate.

'You can do that too, huh?' Ning thought in surprise. He really loved it when he saw the ingenuity of people in using their Aether. 

Suddenly, the assassin moved like a hunter in the night. Ning couldn't even react when he flew past him. By the time Ning realized what had happened, he felt a bit of coldness in places he shouldn't. 

He looked down and saw that his left arm had fallen off his shoulder.
