thats not how the water pump works but okay. It has two 1 way valves. one on the piston and on the base. There has to be a sealed tube going from the pump down into the water. Sucking the air out of the tube will force the water to come up with eatch pump.

First you pump down and that sucks water past the first valve which closes when the down stroke is complete. Then when you life the handle the water will go through the valve on the piston and get stuck. So now when you push back down the water will come out the end. A little bit of water stays on each valve to help keep a better seal to not let air through. It would be extremely hard to create a sealed well so that you could increase the air pressure enough to rise the water how many feet rather than create a vacuum in the pipe which is a much smaller volume

Sooooo he can create anything with magic but he doesn't want to waste his time, didn't he make the first water pump in like half an hour or something?

Whoever proof-read this missed some spots. Quite a few places have the words strung together or misspelled. I feel for the MC though, I too make things out of convenience but don't really want to bother with mass production.

There's also the fact that the metal-banded bucket in the well was invented after the mechanical water pump. No one in history used a metal-banded bucket because the metal would just rust after the first day of using it. You might make a metal band in order to tighten the planks together, but you'd have to replace it with rope or something. Until galvanization technology was invented, metal in and on buckets wasn't a thing. These people are living in a post-apocalyptic society that is using technology that they have no idea how to reproduce or maintain properly.

Not even three chapters in and the hot springs trope has appeared. How utterly exciting...
Oh boy, aNothEr HoT SPriNg cHaPteR iN an IsEkAi MAnGa.
What is it with the hot spring trope always being there.
The mandatory onsen chapter appeared quite early. It's a shame that the only people we see using it are little kids and the MC. At least this mangaka is aware that these are only possible in geologically active areas, and you have to seek them out even then. Most of the time that an isekai MC makes a hot spring they just kind of plop one down wherever they feel like it.
