Underage marriage? No problem. Sending minors on life-threatening missions? Just fine! Making minors take on roles only adults should? Is there a problem? But underage drinking? Nu-uh! Not possible! Big no no!
It's always the same with isekai. I wish these authors would just stop dancing around the alcohol thing so much. The MCs already do tons of things only adults should be doing, what's so different about drinking some alcohol?

Especially since medieval type societies normally had alcohol for all ages at low strength instead of water... Though magic would definitely make the need less, probably they didn't have the same worries we do about driving or the like. ...Magic could also probably cure drunkenness, so probably not as big an issue anyway.

That would be understandable. But I'm all these isekai it's always "I can't drink, I'm still a minor!"
Like bitch, in this world you're considered an adult at 15, you've been fighting life am death battles against monsters for years, you received you're own title as a baron with all the responsibilities that come with it, and there are already 2 girls lined up to marry you. You're not a minor in this world, drink the damn alcohol!"

I'm not sure (because I'm not from Japan) but I imagine it has to do with censorship and ratings.
In manga that is supposed to be violent with lots of fighting, there is rarely any gore. Also, there may be suggestive behaviors and appearances but not much (or any) sex.
I know that the behaviors of minors can have an effect on the rating of media where I live.

The start was a clear rip-off of solo leveling, and the pacing of the first few chapters was horrible. But right now it seems to diverge from solo leveling, even if a little. I must admit it gives me hope that this manga can become it's own thing, not a copy, but just similar to solo leveling. (which is a really common thing in manga anyway.)

Here I thought the manga would be really interesting for a moment. Actually going for the kill when your opponent is cheating like no tomorrow and is trying to end you after already losing? Heck yea I'm in!
But nope, instead it's another cliché manga about a super op MC that has to hide his powers while trying to live a normal school life, unless of course there's a "Sorry sensei, I must go all out just this once!" moment. That last part is speculation, but I'm like 90% sure there will be such moments in the story...

Right now it's a short chapter of them going into the dungeon, and then like what, 2 full chapters of sex? Got back from the dungeon? Sex. Making dinner? Sex. Taking a bath? Sex. Going to bed? Sex. If the dungeon wasn't so dangerous he'd be having sex in there as well most likely.
I really don't mind sex scenes and harem, if it's done at least decently. But now it's just becoming excessive. Like the mangaka is writing out his own big breasted dog eared waifu fantasies or something.

We each have different levels of ecchi tolerance I guess, I think you're referring to the "ecchi" mangas with barely any actual ecchi which give harem genre stories a bad rap by being extremely dry, and having a penchant of never truly ending properly. ( i.e. the MC getting all the heroines pregnant)
I like ecchi manga that are actually ecchi in substance rather than just in name.
Like this one... sadly I can't think of any mangas to recommend to you off of my head, to compensate for you dropping this one. Hope you find something that's more your speed.

Oh don't worry. I'm currently subscribed to around 270 manga, most of which are some form of isekai/reincarnation/wuxia/etc. I have plenty to read. It's just that I liked the start of this one, and am kinda sad that it went the full on ecchi route, as it's indeed too much for me.
Will still keep reading for another 2~3 chapters, but if it keeps going like this yea, I'll drop it.

Seems like there's finally a wuxia manhua like this that actually lets the MC have his revenge! Lin Feng is going back to his roots, so he better pay them all back for what they have done.
Too many of these manga set a "goal of revenge" early on, but then drag on and on and on and on, and even in 200 chapters still don't get to the revenge part.

So this graduation test is dangerous enough that you could get killed. And it was apparently normal that in the past groups would at least have some "casualties". A graduation test from school where it's normal that at least some students die. Yet they're acting like there's nothing wrong with that. They just gloss over the fact that a school lets students die every graduation test, and accept it.
My question is, what the fuck? Tests are supposed to be simulations to see if you're ready for actual mortal danger. How the fuck is everyone just okay with this?
The story feels a bit rushed, and is cliché at this point. Since there are at least like 4~5 others with this kind of story. But I'll give it a shot, maybe it'll be good.
