Naruto checked the Uzumaki library fully and found out many Ninjutsu, Genjutsu, Taijutsu, Kenjutsu and also Medical Ninjutsu scrolls in the library that was collected by the Uzumaki and Senju clan since a long time. There was also the whole set of Fuinjutsu scrolls and books regarding the history of both Senju and Uzumaki clans since the warring states period. After checking everything, Naruto gathered all the scrolls and books regarding Medical ninjutsu and medical knowledge and passed it to Karin "Karin, these are medical ninjutsu scrolls and books regarding medical knowledge. Learn them well from now." Karin received the books and scrolls and nodded.
A week passed. Naruto repaired a house in the Uzumaki ruins which was in a better condition than the rest of the village and made it his home. Karin started learning medical ninjutsu and also taking care of cooking and cleaning the house. After a week, it was time. Naruto went inside the Uzumaki temple and removed the grass chunins he had captured from stasis and put the Noah mask on one of their face. Suddenly, he started shouting in pain and smoke released from his body. Then he stood as if crucified and a projection of death god appeared behind him.
Naruto held his hand in which a Kunai was placed and forced him to cut off his stomach with the Kunai. The death god also repeated his actions and let out a soul from its stomach, which flew and started floating in the temple. The ninja then fell down face first dead. Naruto then took out Minato's hairs and some of his blood he found in an old cloth in the Namikaze compound and placed it on a scroll on the ground and performed some hand signs slamming his hands on the scroll saying "Reanimation Jutsu".
The other ninja screamed and got covered in paper like material, then the paper pearled off slowly revealing Minato in his Hokage outfit. Minato opened his eyes and looked around to see an unknown place and seeing Naruto in front of him, he was shocked and asked "Where am I?" Naruto smiled and said "Welcome back father." Minato was startled and also frowned. Naruto inserted a Kunai with a paper tag in Minato's body. Minato stood up and asked "Where are we? What did you do Naruto? How did you summon me? Is it the forbidden reanimation jutsu? What happened to the village?"
Naruto just smiled and started speaking "Don't worry. Nothing happened to the village. We are in the Uzumaki ruins. And yes, I summoned you with the impure world reanimation jutsu." Minato sighed with relief hearing the village was safe and asked "Did you leave the village? Why did you summon me Naruto?" Naruto answered "I left a blood clone in the village and travelled here to remove you from the shiki fujin. I summoned you because I promised Nine tails that I will get back his other half. So I need you to seal back the other half of the nine tails which is inside you into me".
Minato thought for a while and said "Naruto, I'm sorry that I had to leave you alone in the village. Are you still planning on revenge against the village?" Naruto shook his head "No. I'll go back to the village after training here for three years. I don't want any revenge against the village. I just want to remove the old ones that are in charge of the village. I don't have any enmity with the people of the village. They are just mislead by Danzo and Hiruzen who spread the rumours that I'm a demon." Minato lowered his head saying "I'm sorry Naruto. I trusted lord third and Jiraya sensei too much and left you in their hands. I should have listened to Kushina".
Naruto just smiled "Don't worry. The past is the past. As I said to you back then, I will not destroy the village until they plan on going against me. So now, will you seal the other half of the nine tails back inside me?" Minato nodded and spoke "Fine Naruto. I'll seal it inside you." Then he did some hand signs and slammed into Naruto's stomach and orange chakra flew from his hand into Naruto. After a while, Naruto was on his knee panting. He then said "Thanks Father". Minato just smiled. "Naruto, since you have revived me and said that you want to train for three years, I'll help you train. Also I have missed a lot of your childhood. It's like me paying back for the mistake I have done."
Naruto nodded "Fine. It will be good for me to train under you for a while." Then both of them got out of the Uzumaki temple and to the house Naruto repaired. Inside the house, Minato saw the red haired girl cooking inside the kitchen, and was surprised and also sad, remembering Kushina. Then he asked "Who's that girl Naruto? I didn't know there were any survivors in the Uzumaki village". Karin who heard them speak, turned back to see a yellow haired man along with Naruto and looked at him with a questioning gaze, but didn't ask him because Naruto had told her not to ask any questions if she wants to follow him.
Seeing her gaze, Naruto introduced "Karin, this is my father, the forth Hokage of the leaf village who died long back. I revived him temporarily using a forbidden jutsu." Karin was surprised that such a jutsu exists and couldn't speak. Minato coughed and Karin came out of her stupor and introduced herself "I'm Karin Uzumaki. Nice to meet you lord Hokage". Minato nodded and said "Nice to meet you too Karin. I thought there were no survivors of the Uzumaki clan left. I'm glad to find one here". Then both of them spoke with each other while Naruto left them and went outside.
Minato learnt her story and about her mother's death. How Naruto met her and also how she followed him. He consoled her and told her about Naruto's childhood and asked her to take care of him. Karin nodded and promised him that she will change his character and make him trust others. Soon, Naruto came back after clearing the bodies inside the Uzumaki temple and all of them had lunch together. Minato was happy seeing his son again. Then Minato told that he would train both Karin as well to which she readily accepted. Thus life started in Uzumaki village.
