Naruto: After defecting, Naruto and Sasuke killed people indiscriminately

After experiencing the massive invasion of the Otsutsuki, the two who survived, Uzumaki Naruto and Uchiha Sasuke, began a wandering life in the universe.
Perhaps it was not their fate, the two were accidentally sucked into the white vortex, and just when they were ready to die, the scene in front of them changed, and it was the Ultimate Valley that they were most familiar with.
The two unexpectedly discovered that they were reborn, and the timeline was when they first fought in the Valley of the End, and they could change many things.
In addition, they found that their power was almost preserved, and they also mastered many scientific research results in the future. These scientific research results are enough to greatly improve the overall strength of the ninja world.
They knew that their next move was almost crazy and would not be understood by anyone, and they did not want to implicate Konoha, so they decisively chose to defect from Konoha and go to find Orochimaru, and once again started this life of wandering!
