For those people who only want to read action, I wouldn't suggest skipping the chapters about business but rather waiting a month or two and then binge-reading all of them.
If the author just substituted a time skip for all these early chapters and simply said "Well, it took about a decade, but now the MC is the richest man in the world and he owns all the dungeons in the world..." then people would complain that it was "too easy" or that the MC had too much power handed to him for the sake of plot. These chapters are important because they detail the process of building wealth so that it doesn't feel like an asspull and also proves that the MC was able to gain all this due to his own planning and foresight. Someone bad with money wouldn't have been able to do what he did regardless of whether they knew the future.
I prefer it this way. Isn't it always better for the protagonist of post-apocalyptic worlds to be competent? Otherwise, how do they even deserve to be the protagonist?
By the way, I noticed several times in the translation (Especially chapter 19) where the sentence structure is messed up. I think this is because of the syntax difference between Korean and English, since I have seen the same mistake where the translation is too literal in other novels and manhwa. It's not a huge problem but often the characters' dialogue looks weird because they might greet each other with a question or ask a question where there should not be a question.
Phrases like "Are you here?" are actually supposed to be "You're here!" and things like "Can I work at a different company?" are supposed to be "I can work at a different company!"
