Naruto: Rebirth of Uchiha, Eating the Thunder Fruit at the Beginning

Is this Naruto or a pirate? The fruit doesn't cost any money at all.

The author first explains why the protagonist is only three years old after four years have passed since his birth. Let's not talk about other ways to reduce intelligence. Isn't this elementary school mathematics also considered incomprehensible?

The plot is a bit off-kilter. The most important thing is that it feels like other people have been put under a halo of intelligence reduction, which is a bit illogical. It feels like some characters have collapsed a bit.

I just read Chapter 7. Let's not talk about whether it's good or not. Is your system just a lottery wheel for drawing Devil Fruits? You've already drawn 4 of them in just a few chapters, and you can't eat two. What's the point of drawing so many fruits? Is this also called a system?

How do you make three years older in four years?
