I write an Isekai about communist revolution until an anime is made out of it

Crawling Forwards

I was all of two minutes into explaining how guns work before the blacksmith asked about gunpowder. Right. Having an actual explosive for propellant is the most important part, isn't it.

"Do you know any alchemists? Anyone who could help me to actually make gunpowder?"

With that, I was out the door, shoving my way through the crowded streets, and inside the door of some alchemist's shop a few hundred feet away from the blacksmith with that poor princess hot on my heels, scouring all the ingredients left lying in unmarked trays while the poor man at the counter tried to greet me.

"Welcome, Offworlder! what do you need? Potions? Poisons? Perhaps you'd like to blow-off the stress of -"

"I need sulfur, saltpeter, and charcoal. I want to make something revolutionary we had back home."

I couldn't actually remember the exact ratios for ideal gunpowder, but fortunately this place had a "testing room" in the back specifically for things like this. I was about half an hour into feverishly throwing different mixes of the ingredients together and lighting them with what was essentially a match on meter-long stick while the princess, the shopkeeper, and a growing crowd watched on like deer in headlights until what was apparently the "master alchemist" of the entire city shoved his way into the room.

"What are you doing?"

"Making gunpowder."

"What? (he actually said that to the princess, before turning to me) What manner of fool are you? Have you come from your 'earth' with nothing? Do you intend to seek the full course of your studies here and now?"

"Look, I don't know what kind of clown college you're running, but I was dragged here to kill a fucker, and this is how we kill fuckers on earth."

After much more bickering, I was finally left to experiment in peace. I did actually get a working ratio after another hour or so of testing, which I left with the shopkeeper along with instructions to tell his friends about my "discovery" while I returned to the street hellbent on getting the other parts of my gun built.

This general trend of me running around and introducing technology to people carried on until the sun had set, the owners of every door I tried to enter met me with a grimace, and, like a trick-or-treater out too late, I wandered the streets for a while until I stumbled into a tavern, where I scarfed down a simple dinner and rambled into the night until the patrons started giving me dirty looks, and I finally decided to take one of the rooms upstairs and go the fuck to sleep.

For her part, the princess had done an admirable job of appearing polite when she finally left to go recover for the night herself, which just left me slouched on a lone bed in a dimly lamp-lit room.

Well, wonderful job, dumbass. You actually got fucking isekai'd, and you're still the same toxic sack of shit you were yesterday. 

Great, well I guess now's as good a time as any to get to work on my social skills. At the very least I've got some legendary recognition to fall back on, though. Anyway, what was that "master alchemist" even trying to say? Probably thought I was trying to make something new instead of reinventing what earth already has, or it was just lost in translation.

So, I guess this is my life now. What in allah's name is even going on here - at a cosmic level - anyway?

Partly out of a desire to keep the existential questions and the spectre of my own personal ineptitude off my mind, partly out of force of lazy habit, and party out of simple curiosity and boredom, I spent the next solid month in Morgenheim, digging as deep as I could manage in order to (re-)invent as much as I could think of. 

To my credit, I'd say I actually got quite a lot done, including:

- a working musket

-a printing press

-a mechanical charger for my phone (which still had some useful knowledge in the images library, and in any case the calculator, camera, and mobile games are still useful. That, and there's not much of a point in selling it off, or trying to reverse-engineer what can't possibly be re-created).

-trying to make a machine-gun. It got jammed by residue from the powder, so I managed to put together some smokeless powder (which could actually be identical to modern powder or fundamentally different, for all I knew) using some substance they called "fire salts", among other things.

-actually successfully putting together an automatic firearm. I don't know why I had a diagram of the receiver of an AK-47 in my images library, but I won't question my past self.

-a working mechanical clock, during the construction of which I said "it's time time" several times. I didn't know if their language even had the appropriate homonyms, but I couldn't bring myself to care.

-introducing that "master alchemist" to the periodic table. I didn't know whether or not that even applied here, but I figured that giving out the table would be my best shot at sorting out whether it worked or not.

-a (barely) working steam engine, even though it'd definitely be a long time before anything of that massive scale could be properly utilized.

-introducing the good people of Morgenheim to such wonderful concepts as calculus, memes, mass-production, representative democracy, fiscal policy, sarcasm, cognitive-behavioral therapy, and existential dread. Ideas like that are certainly harder for people to pick up than a machine, but it's certainly good to put those thoughts out there, regardless.

-Some general knowledge of the local language, which they expectedly just called "common", and mostly picked up while the princess was taking breaks from translating my endless rambling.
