I Am a Man, but I Traveled Through Time and Became Haruno Sakura

I am a man, and I traveled through time and became Haruno Sakura. The crybaby and annoying Sakura is gone and has become a violent woman. There are a lot of regrets in Naruto and I want to change them! Sandaime, Haku, Zabuza, Jiraiya, Sarutobi Asuma, Neji... Youth, let me mess with you! This book has no system. I brought a body-training secret book with me when I traveled through time. I practiced step by step and changed together with the characters in the original book. I relied on the prophets and used everything available to save them. If they all survive, what changes will happen to the trajectory of the story? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
