Starting in the World of Naruto

The sacred tree absorbs natural energy and produces fruits. Kaguya absorbs the fruits of the sacred tree to strengthen herself, but due to the filtering of the sacred tree, it is no longer the purest natural energy. Then the bloodline was passed to Hagoromo, which weakened it further. Then Hagoromo founded the ninja sect and passed the energy seeds to more people. After the energy seeds grew up, the energy weakened again. The subsequent generations of weakened energy created chakra. If the energy value of natural energy is 100 and the energy value of chakra is 20, then the energy value of magic is about 60, plus or minus 10. For example, Kaguya is 90, Hagoromo and Hamura are 80, Asura and Indra are 70, Ninja is 50, and Ninja Family Secret Technique is 30.

It's good to follow Orochimaru at this time, but if it follows the original work, when Orochimaru leaves, will the protagonist follow or stay?

Here's a suggestion, if you want to go with Orochimaru later, it's best not to get involved too much with people in Konoha!
