I'm in the Uchiha Clan, and Rebelling Against Konoha Isn't Going Too Far, Is It?

[Naruto] [Doesn't fawn over original characters] [Doesn't fawn over the Hidden Leaf] [Power fantasy] [No heroine] Uchiha Zui transmigrated into Naruto as a member of a branch family of the Uchiha clan. He had planned to take his parents and leave the Hidden Leaf on the night of the clan's massacre. But he never expected his parents to become casualties of Danzo's machinations, caught between the Uchiha clan and the Hidden Leaf. At that moment, the flames of vengeance ignited in Uchiha Zui's heart. “Ding! Congratulations, Host, on awakening the Three-Tomoe Sharingan and obtaining the Get Stronger with Every Breath System...” “Every breath grants one point of Constitution. There is no limit to the Constitution this System can provide...” “Reach certain breathing and Constitution milestones to receive random rewards.” Just as Uchiha Zui was planning how to exact his revenge, the System arrived. In an instant, his idea of trading his life for Danzo's vanished without a trace. With a cheat like this, Danzo, will you make it through next month... Even if your funeral is a cause for celebration!
