It was a bright day in Konohagakure(Village Hidden in the Leaves) but, in a shanty apartment, naruto was not having a good day.
Yesterday, was 10th October, Villagers decided to have their fox hunt festival, six-year-old naruto, thrown in the bottomless valley.
{Flashback}
naruto was running from the mob that was hell-bent on killing him by any mean's necessary. He ran through a forest until he reached the dead-end and was through off cliff into a bottomless valley.
Naruto closed his eyes when he was thrown off the cliff into a bottomless raven. He has made his mind this was a dead-end for him and readied himself for death.
[Timeskip no jutsu]
At the bottom, after waking up naruto's body was in so much pain that death would be a better option than the half-dead state he was in right now.
{On Surface}
villagers enjoyed that demon, is dead at last he fall into bottomless valley nobody can survive the fall and live to tell that the tale.
{At Bottom}
Naruto was on his four limbs as he moved forward towards the cave in front of him. So his misery came to end.
Cave was an old lab of Orochimaru where he experimented on nanotech for his eternal life, but everyone who ever was injected with nanites was dead. So Orochimaru left the lab in raven before he ran away from the hidden leaf.
After some time, naruto reached the cave. He found a glue-like substance all over the floor and above him that rushed towards his body. nanites ran into his body through wounds, the whole cave that looked like a modern lab before now looked empty. Now it was made of mud and stone.
Naruto passed out in the process, After some time his wounds closed and his body started to repair at lighting speed.
[Time-Skip no jutsu]
After a Few hour's Anbu and the third found naruto's body and checked to see if he was alive, they were relieved he was breathing and healed only unconscious.
Anbu's doctor checked naruto and found he was fine. Every injury he had was healed and he was only unconscious should be awake by tomorrow morning.
Third, asked Anbu's to take naruto home and keep security tight around his apartment.
No one ever thought today was the day that changed the future of the ninja world forever.
