Chapter skip? I feel like there is skip, it said shockwave ore thing was intro in chapter 4.2 but nothing said it and this is chapter 4? Shouldn't this be chapter 5?
The original raw was split into 4.1, 4.2, and 4.3, but they have combined all parts into one. That note is just saying that that page is the start of 4.2.
I guess the ore stuff is just an agreement from offscreen.
I kinda hoping that he isn’t just going to be hopping back And forth exclusively between Earth and the world he’s reincarnated into, it was stated that he could go to more places just plain old Earth, if it’s Technology just head into that sci-fi world that was mentioned in chapter 1, if it’s materials/food, give us a glimpse into that world with dinosaurs and pick up some exotic plants and animals that he could sell.
We don't know the exact details about his abilities. But there might be issue with language and familiarity.
MC can speak Japanese because he was Japanese, but he might not be able to speak other world languages. The only reason he could buy stuff in Japan was because he could ask to do work for the locals and get paid. If he doesn't know the other world language, he might not even know where to go to get the local money.
Also, he can't know what he didn't know. Just because there's a more advanced world, it doesn't mean he knows what can be sold, what is safe and not dangerous, etc. It will take time for him to learn all that, but it all start with the language.
