After a long but short reunion, Minato and Kushina faded out. I went and consoled Naruto and said "Kurama, we'll release you now. Work together with Naruto and at the end of our lives, I will make sure that all you tailed beasts leave peacefully. I'll find you a place similar to the summoning realm and there you can live without any worries. As you have waited for so many years for peace, I promise you that we will achieve true peace. Just trust us and wait for a few more years".
Kurama snorted and said "Fine. I'll trust you humans for one last time." Then I said to Naruto "Lets do it." And naruto released the remaining seal. I was ejected from his mindscape due to the excessive amount of chakra released. Outside, Jiraya and Kakashi was worried and when I got out, they rushed towards me and asked "What hapoened? Is everything fine? How's Naruto?" I smiled and said "Naruto is fine. Kurama is released. Everything went as planned. No need to worry."
After a while, Naruto managed to control the sudden burst of chakra released and started glowing in orange light. And a cloak of orange chakra appeared on him just like in the anime. I looked at it and smiled giving a thumbs up to Naruto. Kakashi and Jiraya was awed looking at Naruto's transformation. I then said "Now, Naruto is the strongest ninja". Jiraya looked at me with raised brows and asked "Even stronger than you?" I said "Yes. he's stronger than me. He has an unlimited supply of chakra and also the sage mode". Jiraya nodded and smiled at Naruto. I then told Naruto to train in controlling that chakra and work with Kurama in perfect harmony.
After another three months, Naruto finished his training Kurama chakra mode and perfected his sage mode with Kurama chakra mode combination. In this month, I perfected my Susanoo and Sage mode. Now I can use one of my most favorite wood release jutsu 'Sage art Wood Release-Shinsu Senju' (True Several Thousand Hands) as well. My chalra reserves surpassed Kage level as well. The only drawback for an Uchiha was their low chakra reserves. Maybe because I had a strong soul and Senju bloodline because of the wish, My chakra level keeps increasing.
We finished our training in Mt.Myoboku and left the place. Naruto asked "Where to next?" I replied "To the land of whirlpools". Kakashi asked "Why there?" I said we are going to get the Uzumaki inheritance. Kakashi then said "I think I'll return to the village. I have nothing to do with the Uzumaki Inheritance and I know that Naruto can protect himself. I nodded and said "Fine. I'll send you back using my Kamui once we reach the eddy village." Kakashi nodded and we made our way to the land of whirlpools.
Once we reached the land of whirlpools, we made our way to the previous Uzugakure. Once there, I used Kamui and sent Kakashi to the village and started exploring the ruins with Naruto. While exploring, we found some underground rooms and entered there by using Kamui to get through seals. After some searching, we found what we were looking for. The Uzumaki temple.
I rold Naruto to stay back and took out two ninjas that I captured in the attack from my Kamui dimension that were put on stasis and still survived. Then I used my Sharingan to control one of them and put the reaper mask on him. As soon as I did that, He started shouting and the Reaper appeared behind him. I controlled him to slice his stomach and dour souls came out. I then took out the 4th Hokage's DNA sample I collected from Orochimaru's lab that I invaded to gather evidences regarding Danzo.
I placed the sample on the remaining ninja and waved some hand signs and muttered 'Impure world Reanimation jutsu'. Soon the ninja was covered in paper like substance and turned ro look like Minato. I then planted the kunai with paper tag onto his back and said "Welcome back Minato san. Nice to meet you again". Minato smiled seeing me and Naruto. He then said "So you found a way to release the souls even from the reaper. Nice to meet tou too. I see both of you are doing well. Naruto this time came running and hugged his father. I smiled seeing their reunion.
Then we both started our training under Minato about fuinjutsus and seals. It took us a lot of time to learn them. Days passed and months passed. Finally we learnt all that Minato knew about fuinjutsus. Then he started teaching us the 'Flying Thunder God'. As I already use Kamui and can sense space fluctuations, all I needed was to learn fuinjutsu to make my own seal. So I learnt it rather fast The difficult part for me was the abrupt change in scenary while using it. Naruto was training hard to create the seal, while I was training to increase my reaction speed to use it without getting dizzy. The sharingan helped a lot as well as I can see in slow motion and more clearly with it.
I also went back to the village once in a while and learnt medical jutsus from Sakura and also finally completed the yinseal and also learnt the 'Hundred healings technique'. Another six months passed like this. We were able to perfectly use the 'Flying thunder god'. Naruto was also happy that he could spend time with his father. Minato was happy that he could personally train his son. Like that we finished our training with Minato. One day, after we wone up, Naruto said "We've finished our training. Its time we went back to the village right?"
I said "Fine Naruto, Say your goodbye to your father and I'll send you back to the village". Naruto confused asked "What do you mean send me back? Are you not coming?" I replied "I have some more work to do Naruto. I'll come back soon. Naruto frowned and said "I'll also stay with you then. Lets go back together after you finish your work." I shook my head and said "No Naruto, I'll send you back first. Anyway I can come to you within seconds with Kamui and you can also do the same with the 'Flying thunder god'. So there's no issues." Naruto nodded and I sent him using my Kamui.
