Perhaps it has to do with his strong willpower. Naruto has always been known for his determination. In this fanfiction, his mental strength could have manifested in a physical way, blocking out pain. Another possibility is that there was some interference with his chakra system that disrupted the normal pain receptors. This could be caused by a strange chakra - based artifact or a new type of training he underwent.
One reason could be some sort of special jutsu or power - up. Maybe he got a new form or ability that suppresses pain. For example, it could be related to his Sage Mode or something new entirely.
It might be due to a curse or a blessing from an ancient being. There could be a hidden entity in the Naruto universe that decided to give Naruto this unique trait. Or perhaps it's a side - effect of a powerful experiment or a forbidden technique that he was exposed to. This would add a whole new layer of mystery to the fanfiction.
