One possible plot could be that Naruto is tied to the log as a form of punishment by the villagers who still don't trust him. He then has to endure their taunts and jeers while secretly using the time to practice his chakra control or come up with new jutsu ideas in his mind.
Perhaps some of the more conservative and anti - Uzumaki elders in the village. They might still hold grudges against the Uzumaki clan and see Naruto as a potential threat. So they tie him to the log as a way to show their power and authority over him.
Well, it could be that Naruto is in a really tough situation. Maybe he's lost his chakra or his friends are in great danger. The holy log might be some sort of ancient and powerful object in this fanfic. He prays to it, hoping for some sort of power or guidance. It might also be that the log has a spirit or some connection to an old ninja legend that Naruto believes can help him turn the situation around.
Maybe Naruto is left behind in training because the instructor misjudges his abilities. As a result, Naruto starts training with a retired ninja who teaches him some old - fashioned but effective techniques. This gives him an edge when he finally rejoins his group.
Well, perhaps Rias, for some reason, abandons Naruto in a dangerous situation where he is left to die. Maybe there's a conflict of interests or a misunderstanding between them. It could be that Rias has to make a tough choice that unfortunately leaves Naruto in a life - threatening state.
Well, it might be about Naruto growing up without Kushina's presence. Maybe he has to face challenges alone and discovers things about his mother in the process.
A plot could be Naruto being tied up by a powerful new enemy who has a personal vendetta against him. This enemy might be from a clan that Naruto unknowingly wronged in the past. In the fanfiction, Naruto's friends would then have to race against time to find and rescue him. Or perhaps Naruto is tied up in a magically - enhanced trap set by a dark sorcerer who wants to use Naruto's chakra for their own evil purposes. His friends would need to figure out how to break the spell and free him.
Perhaps in this fanfiction, Naruto's family leaves him because they fear his godlike abilities. Naruto then has to prove that he can use his powers for good. He could start by helping the villagers who once shunned him. This would lead to a series of events where he gradually gains the respect and understanding of those around him, despite his family's absence.
In this fanfiction, Naruto may find himself in a situation where he's being hounded by people for various reasons - some for help, some for his power. He simply wants to be left alone to live a normal life. So he might start to avoid the village and the people in it, seeking refuge in a secluded place. There, he could explore his own thoughts and feelings more deeply, perhaps even learning new skills or abilities on his own, away from the watchful eyes of his friends and the village.
In this fanfiction, it could be that Naruto's left - eye loss is part of a curse placed on him by an ancient evil. This curse not only takes his eye but also starts to drain his chakra. Naruto then has to search for the origin of the curse to break it. Along the way, he meets some new characters who either help or hinder him. His relationship with Sasuke could also be affected as Sasuke might see Naruto as weakened and try to protect him in his own way, which Naruto would initially resist as he doesn't want to be seen as a liability.
Maybe Naruto is betrayed by someone within the village who sets him up to look like he's dead. Left for dead, he's found by a hermit who teaches him new and powerful jutsu. With his new skills, he plans to return to the village to expose the traitor and prove his worth once again.
