Reborn in Naruto: Becoming an Immortal

The timeline is also quite messy. It must have been the first software for Senju Tobirama and it disappeared. The protagonist of the First Ninja War is really a licker. Anyone who becomes famous in the future will have to lick him a few times.

Tobirama Konoha died in fourteen years, but you, Konoha, are still alive and kicking in twenty years, and even Tsunade is only ten years old. Shippuden Konoha 49th year. Tsunade is already over fifty. The timeline is so messed up

So-so, the protagonist is still not good, hey, his strength is too weak, he is cowardly and forced to reduce his intelligence and add equipment.

It looks great. Keep up the good work!
