Be a Behind-The-Scenes Player in Naruto

My name is Wang Yu. I never expected that I would travel through time, and into such a deceptive world. My current name is Uchiha Yu, and I was adopted by my uncle. I have a cousin named Uchiha Madara. There is also a cousin who is unhappy with me every day, but he dare not say it because he can't beat me. His name is Uchiha Senna. There is also a very cheating system called the "Behind the Scenes Player System" that instigates me to unify the world every day. It's so disharmonious to fight and kill. I just want to be a quiet player behind the scenes, and at the same time, I have a big Crystal Palace... This novel and its characters are purely fictitious.
