If the book contains powerful jutsu techniques, Naruto's combat abilities will improve. He might learn new ways to use his chakra or combine his existing jutsus in unexpected ways.
If the weapon is a chakra - enhancing tool, it will boost Naruto's existing jutsu. For example, his Rasengan could become more powerful, being able to break through stronger defenses.
It can also make him more empathetic. If he learns about the hardships his ancestors faced, he might better understand the struggles of others. Let's say his heritage reveals that his clan was persecuted. He would then be more likely to stand up for those who are being mistreated in the present. He would grow from a brash, somewhat naive ninja into a more well - rounded and wiser one.
His life would become a lot busier. Taking care of a baby is no easy feat. He'd have to balance his ninja duties with looking after the baby. For example, he might have to cut short his training sessions or decline some missions at first.
His power level would likely increase significantly. If he wished for enhanced ninja abilities, he could become even stronger than he already is. This would make him an even more formidable opponent in battles.
His confidence would probably soar. Knowing he has his parents, who are likely strong ninjas, supporting him would make him feel more secure. He might become a bit less reckless as he now has people who care about him deeply and he wouldn't want to worry them.
Well, it would be a huge shock for Naruto. In the original, he had no idea about his family. If they were alive, Naruto might not be so eager to gain recognition from the village. His family could teach him things he didn't learn from the academy or from Jiraiya. And his family might have secrets or powers that could help him in battles. Maybe his father could teach him some advanced space - time jutsu. It would also add a new layer of family drama to the story, like dealing with family expectations and reuniting with long - lost relatives.
It would change the combat dynamics a great deal. Guns are much more powerful in terms of long - range attacks compared to traditional ninja weapons. This would mean that strategies for battles, both in the village and against enemies, would need to be rethought. For instance, the importance of cover and stealth would increase significantly.
If Naruto finds a buried book, it could speed up his training. For instance, if the book contains advanced chakra control techniques, he can quickly master them and become stronger.
If the scrolls contain difficult knowledge or a great responsibility, Naruto might become more serious. He would have to grow and adapt to handle whatever new situation the scrolls present. For example, if there are dangerous jutsu in the scrolls, he has to be more cautious and mature in his decisions regarding their use.
It will likely make him more confident. With this new power, he'll be able to take on tougher challenges and succeed. This success will boost his self - esteem.
