The Search for Somethingness: Shinobi Training System in the Narutoverse. Somethingness

[DROPPED]
What happens after you die?
Depending on the religion or doctrine, it could be a lot of things. Heaven, hell, purgatory, limbo, samsara, or absolute nothingness.
But, even taking all of this into account, very few consider reincarnating into another world.
That is what happened to me.
I died and woke up hearing two foreign heartbeats. My mother’s and my brother’s. The only people I had ever wanted to protect.
But, who knew I would be reincarnated into this chaotic world. A world where magic known as chakra runs rampant and a single person can destroy a country by making funny positions with their hands.
I reincarnated into the world of Naruto. And the only way I could protect those close to me, become the strongest and eliminate all of the dangers.
Am I becoming a monster or a saviour? Both, but none at the same time.
I am becoming a warrior. A ninja. A shinobi.
Everything with the help of a system that does nothing but teach and only grants me three single uses of a cheat every other transmigrator seems to have.
Really, how is that fair?
