People start to be more open and friendly towards each other, all because of the baby Naruto found.
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.
Perhaps the baby has a connection to an old enemy. Naruto has to deal with the possibility that some of his foes might come after the baby. So he has to increase security around the baby and also figure out how to break the connection if it's a dangerous one.
He could decide to protect the baby girl himself. Naruto has a big heart. He might see the baby as someone he needs to look after, just like how he was always looking out for his friends. Maybe he starts teaching her some basic ninja skills when she grows a bit older.
Well, Naruto might take the baby wolf to his home in the village. He could raise it as his own, teaching it ninja skills when it grows up. Maybe the wolf would become his loyal companion, like how Akamaru is to Kiba.
Well, he could try to find the baby's family. Maybe he'll start by asking around in his town, using his detective skills. He might also get some help from his friends, like Scott. They could use their knowledge of the supernatural world to figure out if the baby has any special powers or if it's in danger from other supernatural beings.
Perhaps Hinata will be really confused at first. She could ask her friends for help, like Naruto. Together, they would try to figure out where the baby came from and what to do with it. Since Hinata is kind - hearted, she'll surely do her best to keep the baby safe and comfortable.
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.

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.
