[Naruto] Indra from the Cultivation World

Indra:

When did I become the founder of ninjutsu?

Those were spells, spells!

That stuff is spiritual power, not chakra! And it's definitely not nature chakra!

And another thing!

I'm really a useless five-element spiritual root, not some genius with five elemental powers!

Seriously, when did I become the ancestor of ninjutsu?

Honestly, only those few hand signs in this world do anything at all!?

What else am I supposed to do without them!?

For someone who finally transmigrated to a place where he knows the plot, is there anything more devastating than transmigrating to the distant ancient past!?
