(Invincible protagonist + Hokage + no System)
The last surviving child of the Uzumaki clan, adopted by Hashirama Senju himself, and the top disciple of the Second Hokage Tobirama Senju. Tsunade's closest uncle, the elder brother Jiraiya respects above all others, and the nightmare Orochimaru has never dared to provoke. After 32 years in seclusion, he returns to Konoha to find that everything has changed. He kills Danzo, brings the Akatsuki to heel, ends the ninja wars, and ultimately watches Naruto and the ninja world begin a new life.
(New book underway. Please show it your support.)
Most of the plots in the book are quite reasonable, and the self-created settings are also consistent with the world view. The only drawback is that the writing is not very delicate. Overall, it is quite good.
I suggest you describe the protagonist group a little more. Overall, it's pretty good.
The author's imagination is quite big, and there is a hint of reasonableness in the novelty. Be sure to stick to it until it is completed.
