Naruto + fanfic + no system + retain the original character background + writing.
Boruto is alone, carrying the Pure Eye, Wedge and all future memories.
Even his original destiny line was all laid out by him.
He knows the outcome of everything, but has almost nothing.
His power is limited, and history cannot be easily tampered with. If he is not careful, he will turn into nothingness, so Boruto chose the longest path: layout.
He stayed anonymous and walked before the birth of myth.
Watching the ninja world roll forward step by step according to the trajectory he secretly guided.
Thousands of years later, will the adult Boruto be able to defeat the God of Otsutsuki?
