Comment by SIDRA on D Genesis: Dungeon ga Dekite 3-nen - Chapter 49

@SIDRA 1.5 month. For the basis.

@Le7emeChat  "No, bro. I can't read just one chapter and then go into seclusion for a month—I don’t want to do that. For me, a minimum of 10 chapters is considered 'basic.'

@SIDRA ok, I didn't express that correctly. To see the result of everything they talk about, it will take 1.5 month in the story (in the light novel, they are early december 2018, in the manga they (wisely) did not gave a any year), their research on all that was discuss here will be between their new-year and 3rd week of January (2019 in the light novel).
Based on the speed of publishing of the manga, it will take more than 1.5 month irl to get there, saddly.
