Time Travel into Fu Ren's Biography and Rewrite It from Scratch

I was chasing Naruto Fu Renden at home and my teeth were itching with anger. What the hell did I draw? The protagonist of Shippuden was written so weakly. Isn't that outrageous? I really wanted to get into the TV and rewrite the plot from scratch. "Dingling bell, the host's will is detected, entering, 3~2~1" a mechanical sound sounded. Huh? What's this? Did I wear it? Still traveling through time in a baby? Born on the same day as Sunflower? I seem to have a system, right? What about the system? "Host, this is No. 03201. I will accompany you on the rest of the journey." Fortunately, there is a system, so I will give you a cheat. Then, the gears of fate begin to turn, and the plot will be rewritten by me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
