Naruto: You Call That Sage Mode?

(Rebirth + Invincible + Slice of Life + Fixing Tragedies + Multi-Perspective)

With spiritual energy depleted, Earth's last Xiuxian practitioner is reborn.

To think he was reborn as the "strongest" Hokage, Hiruzen Sarutobi? Then he is truly going to become the strongest Hokage!

Chakra consumes potential? He directly disperses his chakra and starts cultivating anew!

A hundred-day foundation establishment, Golden Core, Nascent Soul, ascending to immortality and becoming an ancestral patriarch!

"Naruto, watch closely, this is the true Sage Mode!"

--

First Hokage: "This kid Sarutobi is simply too strong."

Orochimaru: "I must consider whether this is the only chance in my life to become the Hokage!"

Kaguya Otsutsuki: The Otsutsuki bloodline is completely vulnerable in front of Hiruzen Sarutobi...

Great Toad Sage: He is the true immortal!

Slaughtering from Naruto to One Piece, traversing through the myriad worlds!

I, Hiruzen Sarutobi, shall undoubtedly be the strongest in this world!
