Solution: I think it's in lines of something.
But it's very complicated. You need to complete the steps in exactly that order.
- Yell out loudly against the neck. It won't work, but you'll take your anger out of calculations.
- Make a makeshift time machine - probably a 99.999999% Light Speed spaceship, and have it travel two years. If by some chance Earth is new Venus or that everyone you know is long gone...
- Create big enough black hole. It's a warranty of multiverse travel. You only need to resist the intense gravity, though.
- By some chance you could land in the past. Ask Aztec shaman to help you.
- When he does want to sacrifice you, flee, go into another black hole into brighter future, and hope the nanomachines, son trope will kick in.
P: Out of focus, really.
