Naruto: Borrow the Future, Turn the Consequences into Causes

Forty-eight years in Konoha, the Nine-Tails is in chaos. Namikaze Minato prepared to seal away all the zombies and sacrifice himself, while Uzumaki Kushina said goodbye with eyes full. Uchiha Ao was on the ruins, looking at the countless afterimages looming in the sky. That's him in the future—— He is the Spirit King who rules the three realms, he is the Pirate King who dominates the sea, he is the Hokage who became the God of Ninja, he is the Super Saiyan who has stepped into countless worlds, and he is the only true immortal in all eternity... The system told him that in countless possible futures, Cang would be invincible in the world in various ways. In order to protect our weak selves now, those in the future will lend their power to the past. As the interest on the loan, what Cang has to do is to make up for the cause and effect. Borrowing the power of Spirit King Cang, he will work hard to practice his spiritual power and learn the ghost way. Borrowing the power of the Pirate King Aang, he will go to sea to find Devil Fruit and inspire his domineering power. Borrowing the power of Saiyan Cang, he wants to find the blood of Saiyans in the vast universe. "Although I have to pay it back in the future... But I am really strong now." Cang stretched out his hand and gently touched the fateful string named "Spiritual King". That night, the black-haired baby transformed into a young man, with everything under control! "Kyuubi, this 'black coffin' is the interest collected for me in the future."
