He might find that the jutsu scrolls are not as straightforward as they seem. There could be some sort of hidden message or a requirement to unlock the full potential of the jutsus. For example, the scrolls could be protected by a chakra - based lock that only Naruto's unique chakra can break after he has passed certain trials. And once he does unlock them, the new jutsus could change the way he fights completely.
Well, it could lead to him uncovering secrets about his family. Since he is an Uzumaki himself, these scrolls might have information about his parents or ancestors that he never knew before. This could give him a deeper understanding of his heritage and place in the ninja world.
He might start training with it. Naruto is always eager to improve his skills, and a new sword could be a great addition to his combat abilities.
Naruto could find a book that tells the story of a great hero who was just like him, full of energy and a desire to protect. This could inspire him to new heights. He might also accidentally trigger a trap or a hidden mechanism in the library while exploring, leading to an adventure filled with challenges and puzzles to solve.
Well, he might put on the suit and suddenly feel a new sense of confidence. Maybe he uses it to infiltrate an enemy hideout. He could pretend to be a rich merchant or something, and use his ninja skills along with this new disguise to gather intel.
It's possible that the tomb contains the remains of a powerful shinobi from the past. Naruto could learn about their history and the secrets of their power. For example, if it was an Uzumaki ancestor, he might find out more about his own clan's abilities. This could lead to him unlocking new forms of his chakra or even new ways to use the Nine - Tails' power.
Well, he could use the armor to enhance his combat abilities. Maybe it has some special powers like increased speed or strength. He might also discover a connection between the armor and an ancient ninja clan, which could lead to new adventures and unlocking more of his potential.
He could start training with it immediately. Naruto is known for his eagerness to learn new techniques. With the zanbato, he might develop a new fighting style that combines his existing ninjutsu with the power of the large sword.
The baby could turn out to have some sort of special chakra. Naruto, being curious and always wanting to help, tries to find out more about it. He might seek help from Kakashi or other experienced ninjas.
In a fanfiction scenario where Naruto finds a lightsaber, he could potentially incorporate it into his fighting style. He's always been creative in combat. He might use his ninja skills like speed and agility along with the lightsaber's unique capabilities. For example, he could use his shadow clone jutsu and have his clones all wield the lightsaber in different ways to confuse his enemies.
Another possibility is that the robot is from a future where ninjas no longer exist. It could be sent back in time for some reason, and Naruto is the key to its mission. The robot might need Naruto's help to change something in the past to ensure a better future. Naruto, being the hero he is, would likely take on this challenge without hesitation, leading to a whole series of exciting adventures.
