One possible plot development could be that Naruto gains new powers under Zeltrech's guidance. Zeltrech might teach Naruto unique magic or combat skills that are different from the ninja arts he's used to. For example, Naruto could learn to manipulate magical energy in ways that enhance his already formidable strength.
Another plot development could be that with Sarutobi as his adoptive father, Naruto has access to different mentors. Sarutobi could call in favors from other great ninjas to train Naruto.

Maybe he gets trained by Kakashi earlier, or even has the chance to learn from some of the retired or older ninjas who usually keep to themselves.
The plot might involve Naruto being trained by both Kurenai and Asuma to become a more well - rounded ninja. Kurenai could focus on his stealth and genjutsu skills. Naruto, who has mainly focused on his ninjutsu and taijutsu, would benefit greatly from this. As for the relationship with the village, with Kurenai and Asuma as his adoptive parents, Naruto might gain more respect from some of the villagers who previously looked down on him. This could also lead to changes in how he interacts with his peers, like Sakura and Sasuke.
Naruto might become more reserved. Growing up under Zeltrech, he could be exposed to a more sophisticated and perhaps less rowdy environment compared to Konoha. So instead of his usual loud and brash self, he could develop a more calm and calculated side.
Well, in this fanfic, Naruto could start to heal from his past neglect. Tsunade might introduce him to different aspects of the ninja world that he was previously unaware of.

In terms of his growth as a ninja, Tsunade could also help him master some of the more advanced medical ninjutsu. This would not only make him a more versatile shinobi but also give him a new skill set to rely on in combat. And of course, their relationship could also face challenges, like when Tsunade has to make difficult decisions regarding the village that might put Naruto in a tough position.

His relationship with Sasuke could also be affected. Maybe they would become rivals in a more positive way, with Naruto having a stronger sense of family and purpose because of Hiruzen's influence.
