Already explained this in detail. Not going to go into this again. Furthermore, it only takes a bit of common sense to look at the scenes: Deva is thinking (it isn't even a reactionary moment), Narutos' attack, get hit and thud to the ground and then disappear. Now in order for that to work, everything should be at least, somewhere in-between super-sonic and hyper-sonic speed to far exceed the small part of 1 second where FRS crossed?
Can someone really thud to the ground from a standing position faster than hyper-sonic speed - and I am not even counting the lag when the clones disappeared? Can someone form a thought - properly strung sentence - and then count at the same time, when even reactionary impulses (pulling a hand from a stove) only travel at 100 - 107 m/s? Thought speed is a lot slower (20 - 30 m/s) by comparison.
You must be joking. It is clear as day that this happened no where near 1 second. When I say 3, I am actually being generous.
