Naruto's Invincible Ring

My name is Wang Jian. I never expected that I would travel through time, and into such a miserable world. My current name is Uchiha Takeru, and I was adopted by my uncle. I have a cousin who has a gentle and watery expression on his face every day, named Uchiha Itachi. 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 Sasuke. There is also a very deceptive system called the "Divine Ring System" that tempts me to unify the world every day, and yet always threatens me to stay away from it for the rest of my life. It's so disharmonious to fight and kill. I just want to be a quiet and handsome man and have a big harem... This novel and its characters are purely fictitious.
