Naruto: Injury-Free Eight Gates, Shattering Susanoo With One Kick!

Transmigrating into the world of the Hokage, he becomes an utterly ordinary six-year-old orphan of the Uchiha Clan.

With less than a year left before the "Night of the Massacre," and that "oh-so-filial son" named Uchiha Itachi about to raise his butcher's blade, Uchiha Xin is utterly panicked.

Run away? Konoha's Anbu aren't pushovers. Spill the beans? Danzo's formalin jars are already thirsting for fresh specimens.

Fortunately, at this life-or-death juncture, the [Ultimate Sharingan System] awakens! All he has to do is use his Sharingan like crazy to grind proficiency and evolve without limit-from a single Tomoe to the Mangekyo, and even beyond the Rinnegan!

But as a six-year-old child, what is he supposed to do about his pitifully small Chakra reserves?

Ding! Starting draw: God-Tier Passive [Enhanced Eight Gates Formation]!
No injuries! No side effects! Keep the gates open permanently!

Most terrifying of all, every gate he opens triples his maximum Chakra!

While everyone else is still diligently practicing Hand Seals, Uchiha Xin has already embarked on a wildly unconventional path of overwhelming brute force.

Not enough Chakra? Open a gate! Not enough ocular power? Open a gate!

One year later, beneath a blood-red moon, the Night of the Massacre arrives right on schedule.

Carrying a long blade dripping with blood, Uchiha Itachi coldly pushes open the courtyard gate-only to come face-to-face with a six-year-old child with all Eight Gates open, scarlet eyes, and Chakra surging around him like a tangible tsunami.

Watching his younger cousin crush Susanoo with a single kick, Itachi sinks into profound self-doubt.

"Hey, cousin. That blade you were raising just now... who exactly were you planning to kill?"
