They might leave because they want to start a new life away from the chaos and politics of the village. Naruto and Sasuke could head to a remote island. There, they build a small settlement and start training the local kids in ninjutsu. They also use this time to reflect on their past and heal from all the traumas they've been through.
In this kind of fanfiction, one possibility is that they go on a journey to discover new jutsu together. They might leave the Hidden Leaf Village to find a place where they can train without the constraints of the village rules. Maybe they encounter new and powerful enemies that force them to rely on each other more than ever, strengthening their bond.

They could end up in some ancient ruins where secrets about the Uchiha are hidden. Along the way, they have to face challenges like lack of supplies and hostile ninjas who don't want them to uncover those secrets.
