...but let me offer the alternative viewpoint. As mentioned, this isn't a cultivation story, it's a misunderstanding story. And it's a very rare story that manages to hold my attention with this premise, because it relies on the main character being a total moron with no awareness, as well as having an audience (in story i mean, not us, the readers) ALSO being morons who don't understand.

So like here, he thinks he gets transferred to a cultivation world, evidenced by the fact that it's totally different than his prior post-apocalyptic world, as well as seeing 2 'cultivators' face off within moments of him arriving.

And yet somehow, they were actors filming a wuxia series, and he SOMEHOW missed the fact it was staged. Leaving alone the staged nature of the choreography, what about the cameras? The cast? the post-production special effects? You expect me to believe that not only was all SFX used with real explosives, the cameras were also either so small they were invisible, or literal miles off and yet still captured the action perfectly?

So yes, the MC thought he was in a cultivation land, and then somehow manages to comprehend ACTUAL cultivation from a crackpot fake monk con artist. Then he goes down into the 'lower world' and somehow gets entangled with twitch streamers who fake being cultivators, concocts an actual pill and such, and the charade continues on.

Needless to say, the entire premise was a complete waste of time for me. The absolute sheer suspension of disbelief required for ANY part of this is obscene. I can enjoy a comedy as much as the next guy, but the very premise of this story requires everyone involved to be morons. The absurdity of him finding actual cultivation I actually ignore, because that's very common in comedy. (Take Eminence in Shadow for example, the fact that all his chuuni predictions turn out to be real, as well as his ability to punch harder than a nuke, and so on). It's the fact that the INITIAL premise is flat out untenable is what ruins it. After all, the MC came from a fight-for-your-life post apocalypse, rooted in a scientific society. Yet somehow he loses all rationality. It just completely rubbed me the wrong way.

I actually enjoyed the first few chapters as he was figuring out cultivation and was about to descend the mountain, because I was expecting a fish-out-of-water where the rest of the world thinks its fake, but he knows about the secret society of cultivators, shown to him by accident! ...then it comes out it was a film set, and suddenly the fact he MISSED the cameras and crap ruined it all. Honestly if he had seen a movie of them and thought they were Historical Records or something (like Galaxy Quest, someone taking fictional broadcasts and treating them as true history) that would've been one thing. But nope, he somehow saw a film set and missed the cameras/support staff/SFX/retakes/other things.

...just ruined. To be fair, it's not exactly bad per se, just absolutely not what I was expecting, and the initial misunderstanding requires impossible suspension of disbelief.

Read till chapter 20s

So basically, let me repeat a note from the publisher that is present in one of the chapters.
This manhwa is an original work. Yes there exists a novel with the same name and a similar start but both stories take a much different turn afterwards and i think the manhwa does it much better.

the summary does a decent job at explaining the core twist of this manhwa. Which will get revealed once you read it but if you really want me to say it then-
no, this is not a cultivation manga, at all.
this is a comedy series about a misunderstanding the MC has that he thought things that are normal aren't actually normal, and the misunderstanding is hard to resolve because he's rightly very cautious cause he thinks one wrong move will get him killed, thus better safe than sorry.

It can get a bit repetitive and obnoxious tho so we'll have to see how it progresses.
once again, this goes in a much different direction than the 'supposed' novel, in which the MC doesnt really have this misunderstanding.

Anyways i'll rate it like a 8.5 of 10
really good and entertaining comedy but it depends on how it progresses
