Naruto: From the Start, I Deduce Immortal Arts and Shock Konoha

[Hokage + mastering every art through deduction + unstoppable power fantasy]

Uchiha Xiao Huo transmigrates to the Hokage world and awakens the System for deducing every art.

He can deduce ninjutsu, sage arts, and everything under the sun.

Watching the people below unleash their ninjutsu,

and Madara Uchiha laugh without restraint,

Uchiha Xiao Huo asks, “Are you all playing house? Can I join in?”

He extends his right hand, which transforms into a palm that blots out the sky, seizes the moon sealing the Ten-Tails, and hurls it at everyone.

“Now that's fun.”
