*starts charging up the chakra in the fingertips on both of his hands*
He decides to to the technique with both of his hands, because he wants it to be stronger. When he thinks that he has enough chakra for this technique to be successfuly performed, he stops. Now, he feels every single part of the chakra in every single finger tip. He raises his hands with having the figers separated, high up in the air. Already while the fingers are still up in the air, he slowly starts releaseing the chakra fomr it and the he swings down with his hands. As he's doing that, he releases all of the chakraand severely uses shape manipulation and makes a single, small looking and thin wind stream coming out from every finger. As he swings, he tosses the wind streams towards the sensei's clone. While the treams are travelling, first he controls the ones that come from one hand to form into a bigger strem, same for both hands. And then, he controls the two streams and they form into a one big wind blade. He has a blade ready, when the streams get approximetly five meters away from him. At the peak, he claps with his hands, causing the blade to spread into an enormous hurricane going towards the clone. The hurricane simply destroys the clone and cuts it up in pieces. When I think better, it doesn't cuts it in pieces, because one touch with the wind hurricane, makes the clone dissapear.
