Reincarnated in a Different Game World, but I Already Know the Strategy by Heart

Let me start with a few words of digression. It's amazing how this book managed to keep me almost alone for more than two months. Going back to this book, as of now, the main body is an adventure in a different world with a strategy, but it also has a game background. The goal (main line) is to strengthen oneself, find the person behind the other world, and then go home? Then there are a lot of things in the content, and the writing style is a bit rough. Overall, I wanted to watch the ending, but I didn't want to watch the middle part (it was uncomfortable to watch). Just purple~
