Well, Naruto's ability to learn quickly as a ninja would help him in farming. He'd be able to pick up on new farming techniques fast. Also, his observational skills, which he honed during his ninja training, would allow him to notice any signs of disease or problems in his crops early on. And his teamwork skills could be applied when he has to work with other farmers in the village, for example, during harvest time.
Naruto's chakra control, which he has developed over years of training, would be crucial. He could use his chakra to heal any wounds the dragons might get. His knowledge of elemental jutsu could also play a role. For instance, if the dragons were cold, he could use his fire - style jutsu to warm them up. His combat skills would come in handy when training the dragons to defend themselves. He could spar with them in a way that helps them learn how to use their own natural abilities effectively in a fight.
His dexterity as a ninja would make him very good at handling fabrics and sewing. He could use his quick hands to stitch together complex designs in no time. Also, his ability to concentrate, which he has developed during his ninja training, would allow him to focus on the small details of the clothes, like embroidery or adding small accessories.
His chakra control would be a huge advantage. He could use it to precisely manipulate the heat of the forge, ensuring the perfect temperature for the metal. Also, his speed and reflexes, honed as a ninja, would allow him to work quickly and accurately when shaping the metal.
Naruto's ninja skills would have to adapt in several ways. His tracking skills, which he learned as a ninja, could be used to find lost demigods or track down powerful monsters. His ability to sense danger, which was related to his chakra sensing in the Naruto world, could be translated into a new form of danger - sensing in the Percy Jackson world. He could also use his ninja - style parkour skills to traverse the different terrains in the Greek mythology - based world, like climbing the sides of Mount Olympus or running across the rooftops of ancient Greek cities. And his skills in using ninja tools could be combined with the use of demigod weapons, creating a whole new combat style.
His speed could translate into quickly gathering and processing evidence. Naruto was always quick on his feet during battles, and in the legal world, this could mean he can outpace his opponents in terms of getting the necessary paperwork and facts. For example, he can be the first to interview key witnesses.
His ninja skills would be more focused on stealth. Vampires are known for their ability to move quietly and undetected. So Naruto would likely incorporate that into his fighting style. He might also have enhanced speed, which would make his attacks faster and more unpredictable.
Well, Kakashi has a lot of unique jutsu. He could share some of his knowledge about them with Naruto. For example, he might teach Naruto some of his lightning - style jutsu in a simplified form. Also, Kakashi is good at stealth, so he could train Naruto in that area, which would be very useful for Naruto in both combat and espionage - like missions.
His taijutsu might be more refined. Rin, having trained with Kakashi and Obito, could pass on some unique close - combat techniques. Naruto might also have a better understanding of chakra control from an earlier age. Since Rin was good at medical ninjutsu, Naruto could potentially combine that with his own chakra - based attacks in creative ways.
His speed could be used in sports. For example, he'd be great at track and field events. His ability to sense danger could help him in security - related campus jobs.
Naruto could use his shadow clone jutsu to multitask in the kitchen. One clone could be chopping vegetables, another boiling the broth, and he himself could be preparing the noodles. His speed and agility from being a ninja would also help him serve customers quickly.
