Europeans would show up and my Native American homies would be armed with cartridge rifles, six shooters and a crank rotary machine gun.

I would try for better, but I think there just wouldn’t be the time for fine tooling more advanced fire arms would require. Even getting all that going before I croak is going to take a lot of ambition.

Also assuming they don’t think I am some evil spirit that they quickly kill when I demand industrial metal facilities be constructed.

Oh, they would probably also have penicillin before the white man, so that would be a major advantage.
