Also, this is a super whiny comments section, and most of the complaints are very silly. Like, people get so freaking triggered over a false rape accusation, but those same people will happily read a slave harem isekai and laugh heartily, cause anything's fine if you can't relate to the person getting victimized. At least in this case it's just a stupid joke, get over it.
And everyone's complaining about the author not knowing anything about camping, even people who themselves admit they don't know anything about camping. As someone who's gone camping, everything the MC does in this chapter is perfectly valid.
And then people make fun of the MC for not drinking his own piss in the middle of the Sahara desert. Newsflash, this is a manga with a realistic tone, depicting what could plausibly be a normal person enjoying a normal hobby. He's not supposed to be Bear Grylls. That kind of survival expedition may make for good TV, but it's not something you do for fun by yourself.
