This isnt the most important thing of the chapter but im still not satisfied with those explanations about the chidori shield. Seems that people want to believe things so bad that they even invent their own (completely amazing) theories.

First of all, when was chidori transformed into lightning? I mean yeah kakashi was said to cut through ligthning but what the hell has that to do with chakra transforming into electricity?. Chidori was nothing but a lot of chakra in one part of the body. You release that chakra in a burst (with something called body activation, still thinking about this) to get the destructive power.

Now appears that that chakra burst is released through all the body (im not even going to say how much chakra this thing could burn, or the strain to the body, if chidori in one hand was painful and give lots of strain imagine that in all the body). It should be just chakra so yeah it can throw you back but electrifing? what the hell has electricity on a sword to do with it being able of cutting kunais like butter? Chidori transformed into electricity and if its used on a sword it becomes laser? The laws of physcis are quite f.ked in naruto world, at this rate even existence could disappear in a spacetime vortex (kakashi blinked ).

The only thing with sense I have read about it is that it could be another technique that got the chidori name because its similar to it but it has nothing to do with it... then why call it chidori??.
