Naruto: Strongest Minato

(This book has no system, slow to start, and only has a female protagonist. Let's see how Minato becomes the strongest in the ninja world step by step!)

"Hokage-sama, Hokage-sama, may I ask how you became so strong?"

Minato thought for a moment and said, "It all started when I fell off a cliff when I was five years old. I was climbing to train, but I ran out of energy and fell off a cliff, and that's when I learned some magical skills."

"Ah? It's that simple?"

"Of course not, this is just the beginning of my legendary life!"
