There is a mistake in the anime or manga. Because Nagato bodies don't feel pain. This was shown when the body was in genjutsu. So it's funny that during physical ninjutsu attacks they scream in pain. In any case, there are a lot of mistakes and a lot of stupid solutions that the author of the manga came up with. Which somewhat spoiled this work. And Boruto has already literally killed this shinobi world. Nevertheless, I love the Naruto manga, but I would prefer a different series than Boruto. As they say life!
