Alex looked at the floating piece of the blade just next to the crack in space. It was so close that he could just reach in and pull it out.
Qi didn't seem to work there, so if he wanted to pull it out, it had to be done by hand.
However, that was not what Alex intended to do at the moment. What he wanted to do was instead push it further. So, he took the other half of the blade that was still attached to the hilt and used it to push the floating blade deeper into the crack.
For a while, nothing happened. However, at some point, the blade suddenly vanished from his sight, gone somewhere never to come back.
Alex waited but that was indeed the last time he would ever see that sword. "So it disappears if it goes any further huh?" he thought.
