What place do I get teleported to? If I’m teleported to the same place on Earth, then I just fell down several meters into a swamp and am probably going to die here.

I would teach London children the most obnoxious brain rot slang from today as a laugh.

Wouldn’t I be in like empty space?

This is very A Connecticut Yankee in King Author’s Court

I hated that book. So pretentious.

I would warn the Native Americans about the Europeans

Well, staying in the same location? I’m in the US, so… I’d probably try to get writing invented. To my knowledge, besides some of the Central American empires, there’s no evidence or even claim of there having been any kind of writing or system for making information durable. I know there’s a lot of clay here, I’m pretty sure we could bake clay tablets to store down information. There’s also tule reeds here that were already being extensively used, and those could probably be made into a kind of paper as well. As to whether the people would accept that, I have no fucking idea at all; what we know of the California tribes suggests they were always semi-nomadic, but that’s all very well into the post-contact period and much of what we know was written down by the Spanish while being the biggest bastards they possibly could to the locals. I dunno how useful record-keeping would be to a nomadic people. It’s also entirely possible the people would be like “uh, yeah, we know how to write, dummy”, and it was just lost in the multiple waves of pandemics.

I think probably something that -might- be achievable is figuring out glass. I’m mostly sure that if the native Americans had glass, we would have seen some sign of it in the archeological record by now. I’m sure some smarty pants is going to come along and tell me “you can’t just throw sand in a kiln and make glass, you need a special kind of sand blah blah blah and here’s 99 reasons why that won’t work”. Yeah, you’re probably right, but I don’t know any better, so I’d still definitely try. I also remember reading that clear glass was a thing figured out near Venice when they started adding grass ash or some shit to the sand, so I’d definitely experiment with that, too. Glass is just dead useful -and- pretty, so I’m fairly confident I’d get some acceptance that way.

I would say metal smithing, but the only metal deposits nearby that I know of are mercury and gold. You can’t make nails and tools out of mercury and gold.

Also, maybe water wheels? To my knowledge, we have no record of native Americans using water wheels for work (I.e. grinding corn or acorns into flour). I think if I managed to put a basic water wheel together, I’d be pretty popular.

I would kill everyone I meet with the plagues I carry which I’m immune to.

Double entry accounting system.

I’m an accountant by trade. The double entry system wasn’t invented until the 15th century.

I could account for any lords various assets, goods, and livestock in an efficient, reliable and accurate manner

Die because my medications haven’t been invented yet.

Or be murdered because I’m not christian

I’d use my knowledge of history, politics, psychology and science to become an influential advisor to powerful lords and help them conquer the world in exchange for living in luxury.

Die as you forgot to teleport me to where the earth was at the time.

Otherwise I guess my main knowledge that could be useful is some basic first aid. Secondary to that, a little bit of electrical stuff.

Good thing I binge isekai anime

Fly under the radar as much as possible, find a cute girl and settle down and have a lot of kids.

I know thousands of songs. Also, musical instruments like the saxaphone haven’t been invented yet.

Anyone else a fan of Nate Bargatze?
