This manhua is pure wish fulfillment. As if the author is writing out his own fantasies or something. The main character is OP right from the start (compared to anyone else in the world he's in), everyone doubts him at first but then he quickly beats them and quickly start praising him as a great master. The women pretty much all need saving. Whole organizations are handed over to him without effort just because he's so OP. You name it. A Mary Sue character if I've ever seen one.
I personally don't mind it. It's not my favourite manga by FAR, but I'll keep reading it for now. Just...don't expect anything deep or original.

Isekai manga tend to leave an impact with good characters or an interesting story or setting. But manhuas like this one don't have any of that. Character is a mary sue. Story is bog standard "arrogant opponent shows up, gets beaten up easily, improve cultivation a bit/a lot, move on to the next arrogant opponent" stuff. Setting is just the modern world but with eastern mysticism thrown in. So it basically has none of the qualities that an impactful manga/manhua should have.
Some do though. Slime datta ken, Overlord, Tales of demons, Kage no Jitsuryokusha, Everlasting sword of god, some revenge isekai, etc.

It's kinda unrealistic how almost every guy that comes into the scene is an asshole, and even the police are more like bad guys than good guys... It's like this is an alternate dimension where being an asshole is normal. >.>
But I guess I'll just have to get used to that as the manga is pretty funny.

Not to this degree... I mean, apparently it's normal for men in this world to constantly harass, extort, or even sexually assault women. While at the same time women walk the streets like there isn't a constant danger of this happening.
I get that there's plenty of assholes in real life. But in this manga it feels like they increased the amount of assholes 10x.

Well for me, the asshole attitude you're talking about on this story is practically fit a real life scenario.
To be honest people are an asshole if you just know how to observe you'll realize the true mindset of a person(in real life) based on their action and words they spout out. I'd say few people(in real life) aren't an asshole once you stop thinking about what attitude or appearance you should do to please those people and start being frank at them( well, in a way that you won't belittle someone if they didn't do anything that hurts you and people you love).
I'm proud having a few friends and distant with my relatives that only knew how to act nice in front of you but talk dirty when you aren't with them.

Once again a manga where the MC gets forced into a marriage because he did something benign that is for some stupid reason considered a marriage proposal in the fantasy world. Ugh... I had hoped this manga would be different, seeing how it started out with him defeating a dragon without others (like the girls) being present.
I'm starting to really dislike how like 90% of these isekai manga end up in a semi-harem or full-blown harem like 10 chapters in. Why can't we have more where the MC is just a badass in his new world, without several or more girls/women clinging to him and bossing him around?
The manga is still interesting enough to keep reading of course, but it certainly dropped a point or two for me with this. -.-

Grain deliberately provoked the team while barely remaining within the rules, just so he could claim to "defend himself" and slaughter them. All just because they looked at him angrily and didn't like him treating his familiars like trash. The female mage didn't do anything to stop any of it. Yet now, when Grain lost and is about to die she decides to step in and wants his life spared? They both deserve to die for this! Grain for being the one doing it and the female mage for allowing it to happen!
I'll be so fucking pissed if Grain's kept alive after what he's done...

Maybe it's because he doesn't think it's real yet, but right now he's kinda abusive towards his tames. ^^;; I wonder if that'll change. For now I guess I'll follow this one. Though I hope the MC doesn't turn out to be one of those that "just goes with the flow" not having any real personality of his own... I really don't like protagonists like that. =/

1: The earl arrived immediately when he was betrayed. Just...how? Why is he there himself? It makes no sense.
2: The knight that tailed the mc clearly had no problems getting in there. Why didn't the earl just send out his own knights to find the book? They would have had a far easier time.
3: The earl FORCED the mc to do a quest way above his level. No player would actually deal with that. Also why didn't the earl just hire someone of higher level?
4: Level -1? Seriously? No RPG would do such a thing. Ever.
This game inside this manga is just so unrealistic. I feel like no player would want to play it when you get screwed over so easily in it. And there's just a lot of stupid premises the story relies on to even start so far. I don't know if this is worth reading or not as so far the story is pretty aggravating to me. Raises far too many "why?!" questions already.

Most of your points can be answered with it simply being part of the game mechanics. I mean NPCs can be teleported whenever and wherever a trigger is performed. There are many instances in games where really they could have done it themselves but still mysteriously require players to do quests, so I can't say it's not "unrealistic" in games. Maybe the earl didn't know of the hidden cave the MC discovered? And maybe they couldn't risk their own soldiers, even if high-leveled, for some reason? I mean, using players to do your bidding is certainly a better alternative since they're "immortal".
Plus while there are level-restricted quests, there are also high-level quests that allows lower level players to participate, though usually they put warnings like recommended levels and such.
The final point, however, is indeed unique. So far, I haven't come across any manga/comics that featured a negative level (I think), but I wouldn't really call it illogical. Perhaps there are hidden game mechanics that only skilled players are meant to find. C'mon, you see it all the time in games -- cheats, easter eggs, or a totally secret element.
Plus, the fact that it's already raising questions may not really be a negative thing, at least for me anyways. It's meant to be answered later in the story since the story is still being set up, so I still recommend to continue reading (๑•ㅂ•)و✧

Anyone else think this story seems like it's a sequel? The prince has such vast knowledge of the outside world, he's also stronger than the previously strongest person on the continent. So where did he get that knowledge from? And how did he get this strong? By just being talented? I doubt that would even be possible. Especially the knowledge of the outside world.
Feels like a ton of important stuff happened before the start of this manga, yet we've seen nothing of it for some reason.
Though I already suspected that he was a reincarnated person, they kept it so vague for so long. Glad to actually get some confirmation in the last chapter.
The thing I'm wondering about though, is why the manga started without any form of history on him. It's like there was prequel before this manga, yet it doesn't exist. >.>
ikr, it's certainly a breath of fresh air from all the other reincarnation stories.
It's certainly different. Not entirely sure if I like it. Though maybe the author just thought "Everyone knows how a manga like this starts by now. Might as well not start with a bunch of chapters about his previous life and how he grows up, and go right to the part of the story I actually want to tell." or something like that. :P
i actually rather enjoyed the non-confirmation from before. it left more room for mystery about the MC which just isnt that common in manga and anime today.
i prefer when the MC has some mystery to them that even we the audience dont know yet because we can gradually uncover more as the story progresses. it's pretty refreshing.
