Well, another development could be Naruto pushing his limits in terms of his physical endurance. He might endure a really tough training regime that not only strengthens his body but also unlocks some hidden potential within him. Maybe he discovers a new form of Sage Mode that's even more powerful than the previous ones.
In this kind of fanfiction, one exciting plot could be Naruto mastering a new and extremely powerful jutsu. For example, he might combine different elemental chakra in a way no one has thought of before, like mixing lightning and water chakra to create a unique attack. This new jutsu could give him an edge in battles against strong foes.
Obviously, Naruto is one of the main characters as the title implies. He's the one who's constantly pushing his limits. Sakura might also be an important character, perhaps as a support to Naruto in his growth, providing medical assistance or strategic advice during his adventures.
One exciting plot development could be the discovery of a new, hidden jutsu that gives Naruto an unexpected power boost.

This new jutsu could help him in battles against extremely strong foes like Kaguya.
One possible plot development could be Naruto seeking out other Uzumaki descendants. He might want to learn more about his heritage from them.
Another development could be Naruto seeking out his real family's secrets. Maybe he discovers that there was a misunderstanding that led to his exile.

One possible plot development is that Naruto could start to explore the secrets of his clan. He might search for ancient techniques or artifacts related to his heritage.
Another aspect could be the relationship between Naruto and his sister. If she is the favored one, she might initially be oblivious to Naruto's pain. But as the story progresses, she could realize how wrong it is and try to make it up to him. This could lead to a complex family dynamic exploration in the fanfiction.
I recommend the novel " Ling Tian Sword God " to you. The cultivation realm in this novel is also based on the sword. There are a total of ten realms, including Sword Master, Great Sword Master, Sword Saint, and so on. The highest realm is the Immortal Sword God. The main character had the title of Immortal Sword God and became a Sword God. I hope you will like this novel.
In this type of fanfiction, a great plot point is Naruto's transformation. He might break the limits of his physical form, evolving into a more powerful and unique state. This could be something like a combination of his Sage Mode and Nine - Tails Chakra Mode into an all - new, never - seen - before mode. It could also include him breaking the limits of his knowledge, learning ancient and forbidden ninjutsu that gives him an edge in battles against extremely powerful opponents.
One possible plot development could be Naruto growing up in isolation, constantly feeling the sting of being abandoned. He might develop a strong sense of self - reliance and a burning desire to prove himself to his family. Maybe he starts training secretly and becomes extremely powerful on his own. Then, when his siblings finally realize their mistake, Naruto has to decide whether to forgive them or hold a grudge.
