Great chapter!
The original sons got reincarnated in every era. I guess, back then it was Madara and Hashi. Now it's Naruto and probably Sasuke.
One thing! What did the sage mean when he said the younger brother gained the same power as the older? Did he also gain sharingan? Since we saw that they were using Susano's to fight each other.
And WTF happened to the sage's brother?
What will he entrust Naruto with? New way of thinking? New power?
And from what place did his mother came? Did she look that "demonic" after eating the fruit, or before?
Maybe the sage's brother become an Uzumaki?!
