One does not simply Escape when being stared at. Any thinking people will question how he is was able to use Buddhist cultivation arts which is not his original cultivation art.
On second thoughts, If you create a dense amount of after-images where you are standing, it should be possible to use those after-images as a smoke screen. As for how far you can run before that smoke screen stops is up to your ability. I mean if you can move backwards fast enough while the person staring at you, still thinks you are in the same spot you can possibly escape.
