take out the tailed beast with their mountain buster jutsu , bring naruto to sage mode level fuse him with pa and ma for a power up, take the rinnegan from sasuke,bring orochimaru back. make suigetsu create the new seven mist ninjas as he is mastering the swords like his brother mangetsu,naruto becomes hokage and sasuke replaces mifune as the leader of the samurai as an organisation that keep the 5 nation in balance and maintain peace(united nations type) truth about the uzumaki clan and have the survivors come out of hiding and start rebuilding their nation,truth about juugo clan , where are they..visit the snake sage place and the katsuyu place,,,the 5 nation leaders(damyo) start to feel like their losing their power over the nations..small villages and nations starting to separete themself from the bigger nations in order to control their own resources and economy...an new enemy with unkown origin and secret agenda starts attacking the 5 nations simultaneously ..lack of trust between nations and most of all ...we should forget all about madara, hagoromo and mostly kaguya like this shit never happen ...it would be better to introduce the new generation
