When I came to, I had reincarnated along with the base fortress from my sci-fi game. What’s more, I was in the form of the female avatar I used in the game. All around me was an endless ocean, with no iron, no fuel, no energy, nothing at all! No matter how advanced sci-fi technology is, without resources, nothing can be made. Despite this, the natives use some sort of incomprehensible technology called magic, and there’s not a trace of science to be found.

There's just, as always, one small catch—he needs to prevent the end of the world first.But as Adom will soon discover, changing history might demand sacrifices even greater than watching it burn...
