Reincarnated as Shisui Uchiha, I Attack Konoha from the Start

He transmigrates to the world of Hokage and becomes Uchiha Shisui.

Then, without warning, the Fantasy Trial System automatically binds itself to him.

"Host, choose a route here with me, and you'll receive generous rewards."

Shisui gives a cold laugh. "Hmph, you useless System. You must have some ulterior motive for binding yourself to me. My Mangekyo is more than enough to let me dominate the ninja world. Why would I need you?"
