Naruto: The Mastermind System

My name is Lu Xuan, and I never expected to be transported into another world—and such a ridiculous one at that. Now I'm called Uchiha Xuan, adopted by my uncle, with a cousin who wears a smug look every day named Uchiha Madara. There's also a younger cousin who glares at me constantly but doesn't dare say anything because he can't beat me—Uchiha Izuna. And there's this absurd system called the "Mastermind System" that keeps urging me to conquer the world, threatening to erase me if I don't. Fighting and killing are so disharmonious. I just want to quietly be a behind-the-scenes boss and maybe build a nice harem on the side.
