KABOOM
That was the last thing that rang through what had been Rock Lee's eardrums before he felt his soul slip freely from his body- discarding it like an unwanted banana peel- as the blast's fiery inferno cooked what had been his skin only moments before. His soul twisted backward into the air and started to fall up at 500 miles per hour. He flew past birds and clouds, though at much too great a speed to notice any of them. He was still in shock from the earlier explosion, and still believed he was merrily being hurled backwards by the blast's force. He was partially right. After all, there was indeed a force hurling him into cloudy oblivion.
But a force can only throw you so far, and the same was true in the after life as well. Even if physics had gone out the window. After all, no living being could travel at 500 miles per hour and come back with every cell still intact. Not that Lee was living now in any way. Which was actually a good thing, because when you're dead, you can't feel pain.
This new attribute came in handy as Konoha's Sexy Green Beast made a very un-sexy face plant into the surprisingly solid clouds at the foot of Heaven's Gate, bruising every inch of his soul's ectoplasm.
It still hurt.
