Naruto: This is how the thunder fruit is used

[Naruto + pseudo-invincibility + devil fruit ability development + single female protagonist]
Traveling through the world of Naruto, Goldfinger only had one thunder fruit, and he was unable to use chakra after eating it. How to choose? Do you choose to continue using the power system of the Otsutsuki clan? Or just throw everything away and just rely on the power of the fruit to dominate the ninja world?
Protagonist: Do you still have to choose? I’ll show off directly.
Purely develop the fruit ability, without mixing in other system powers, and one fruit can reach the bottom.
No cp removed, original single female protagonist
The introduction is weak, please move to the main text.
