Naruto: Sign-In for the Eternal Mangekyō Sharingan from the Start

[System + Invincible + Pure wish fulfillment + Fast-paced + No female lead + the Myriad Worlds]

Jiang Nan transmigrates into the Uchiha Clan just as the Uchiha coup is about to begin. The situation is dangerously tense, and Uchiha Itachi has already been summoned by the Third Hokage. Jiang Nan starts to panic. Who could survive a start like this?

Ding! Host, don't panic! The sign-in System has arrived!

Sign in with the Uchiha Clan from the start!

Eternal Mangekyō Sharingan! The left eye controls space, the right eye controls time!

“You want to kill me? Ask my time rewind first.” Facing the assembled warriors, Jiang Nan remains calm and suppresses them all by himself.

When confronted by Mifune, who kneels and begs for mercy, Jiang Nan listens to his barrage of moral blackmail, then gives a cold laugh. “Every person's life is in my hands. I kill whoever I want.”

“You had your chance to surrender, but you didn't. Now you're going to lecture me about benevolence and morality?”

Jiang Nan's gaze is cold, his eyes like a secluded spring beneath the moon, seeing straight through human nature.

[The protagonist treats human life as nothing, but he isn't cold-hearted. He simply stops at nothing to achieve his goals.]
