Noir, third son of a “beggar noble,” lost his job and was at a loss, but fortune struck just as he was contemplating becoming an adventurer.

Hidden Dungeons that no one knows how to enter. Legendary places full of extremely rare magical beasts, magic tools for power beyond measure and items that would be considered a rarity all over the world.
To such a dungeon the entrance was opened.

“Without telling anyone about this place I’ll secretly become the strongest.”

This world is harsh to nobles of poverty.
Without authority or honor, if I could at least acquire power――

PLEASE TRY TO READ THIS, ESPECIALLY THE 2ND ONE, we might have the same opinion..

the plot was surely interesting. Dungeon, guilds and women, especially having a harem, which is what most men wants. Just that, the MC is too much of a sissy, so uncool and so wimpy. Well personally I hate what the authors made of the MC, it kind of annoying and the MC right of the start is basically a GOD, I mean he can bestow and edit skill, and theres absolutely no limitations, if he has... more>> enough LP he could just delete every skill a monster or a person does and kill them like killing a chicken. I think it was not well thought off when written, I mean, its not like I have no common sense you know, do the author think im dumb?? I mean, the 3 skills his manster has imparted him is basically OP, I have no problems with the MC being OP since its also a nice feeling to be superior sometimes even when its just through watching or reading animes and mangas but its just that I think the author is acting like an idiot, im not saying im smart that I should just write my own novel, its just that its very annoying and I cant get it off my head, damn so annoying.

***Just for example, he easily was imparted with 3 new skills by his master who happens to be a great mage of 200 years ago, this 3 skill functions through LP or life points, and in order to get lifepoints, he just have to fulfill his desire, I mean he just have to do thinks that feels good, for example fulfilling his sexual desires and he gains LP, or eating delicacies enjoyably his LP goes up or becoming rich and spending money his LP goes up, and when hi LP goes up, he could make or bestow or remove any skills into/from any person or a monster as long as he has the necessary amount of LP, and so if it were me I'd just go and f*ck any one I could, eat anything I want, I could even steal or hunt monster as long as it makes me happy, of course as a pervert Id definitely go on debauchery that way I could amass millions or billions or even trillions of LP then ID be like a god.***** its just WOW, so WOW, definitely a WOW. Its like they purposely not include Common sense and other important etc. It this novel. Its really missing the "thought well" part. I especially hate the way MC acts, damn its so unsatisfying, and even the scence where he does thing to the women where so akward that it becomes disgusting, I get chills like, is that even how you act like a dense protagonist? I really hate how they planned the attitude and behavior of the MC, especially in the anime, in the anime, the MC portrayed a very very loser aura, then the loser MC acquires an OP skill (well he literally had an OP skill since the biginning) for the second time and even as the story progresses with him becoming powerful, he still stays with the loser attitude, bahavior and etc., well I dont know how to put it into words so I just your the "loser" word to define him. I think everyone should know that a person changes, no one stays the same from childhood to adulthood until death, a person undergoes changes be it in his attitude, behavior, appearance and figure, especially when a person acquires or gain something significant in their lives we always change for better or for worse, the changes may sometimes be small that its unnoticeable or big that its clear even in others perspective, we always change, because change is constant. Just like the MC if "SOLO LEVELING" >> atleast the author could have retained this common fact and incorporated it in his story so that there could have been some real sense in it. I mean he could have atleast made the MC cooler so that some reader will think that he becomes deserving of his powers and women. A great example would have been "SOLO LEVELING".

well at least I liked the dungeons, levels and stuff. But it was still so bad <<less

*Sigh of slight disappointment*

This story has a long way to go to meet my standards

There are way too many things this story is doing wrong.
Some light spoilers: (read if you want to know what your getting into)
- Typical cultivation premise. Nothing new on the table.
- Thick MC. Really, really thick. His head is alright, it's just around that ONE GIRL he becomes a complete Neanderthal.
- Everything suddenly going the MC's way at convenient times. If this was done more gradually it would have been... more>> less noticeable. Having the MC stumble upon a virtual gold mine (the dungeon) right when the his family is in a monetary crisis was sloppy. The rewards should have come out AFTER he completed a trial of some kind. I can only see the family being infinitely successful from here on out.
- Very forced romance. Some could say it was done in a way that is clever and 'plot stimulating', but the way it is done is just a bit too fast. And it is because of this that the MC needs to be so damn thick in the head. At least his thickness serves some purpose (not bad).
- The name of the dungeon he finds is LITTERALLY NAMED "The Hidden Dungeon Only I Can Enter". Who the hell names a dungeon that?! Obviously whoever made the dungeon failed from keeping other people out by this point!!!
-Don't even get me started on the OP as hell powers.
-The very first monster he finds is a slime that spits disease. That's fine... but its body tastes delicious (MC eats it). If it was an animal type monster, it would totally make sense... but seriously, there is no room to BS my way out of that one. You could wave your hands and say it was MAGIC disease, but get this: The slime is catalogued as 'weakest'. Magic then becomes basically impossible for it. Tada, we have a nice, big, fat, plot hole right off the top of the story. Your not impressing me author. It could have been acid it spat or something, but you went and chose disease because it is most associated with the color yellow.

Despite all these things, I don't believe it is game over for this story. One star for now, and more in the future if the author manages to plug up some of the plot hole, or at least stop making them so fast.

Translator is doing a great job. Three chapters and only one slight spelling mistake. <<less

So far the story has been really enjoyable and genuinely funny. I'm really fond of the MC, his family, and Emma... Emma for multiple reasons :P I'm not usually a fan of ecchi elements but I like the way the author uses it because none of it derails or slows down the plot. If you're anything like me then this is a nice mix of growth and enjoyable interactions... defo worth reading :)

At the start it is certainly an enjoyable fun read. However there are plot holes, the MC is thick at times, the worldbuilding is poor, but it's not intended to be serious, considering the MC can gain the strength of a dragon by going to a brothel. The LP system is literally Deus Ex Machina, and the author forgets how much he has, and is inconsistent. Honestly it's a least a fun read if you don't mind the s*upidity, but later on if you read the syosetu novels in MTL... more>> as I did, it gets extremely annoying.


The MC can buy skills with LP, or Life points which basically he gets whenever the author thinks he needs some, and is horribly inconsistent. It says he gets them for being intimate with the opposite sex, being satisfied or eating a good meal, doing perverse things or eating exotic foods. However, there is absolutely no consistency in how many points he gets. He's also extremely wasteful, never buys basic strengthen skills yet complains about getting stronger, the author says a storage skill can't do something without upgrading it, yet instead of actually upgrading it when they come to needing to a carry a dragon, they apparently don't need to upgrade. If you are reading it out of any interest in how he utilises his so called cheats, don't since he only uses it to weaken enemies, and never attempts to strengthen himself. Since I enjoy cultivation novels, with cheats and such I thought it would be interesting since he didn't seem to immediately get OP skills, however it's actually because it's a slice of life novel.


The title is completely misleading, and the strength of other people in the world is poorly explained. Even as a slice of life harem, it's cliché and not great. I'm sure some people might enjoy it, but it's certainly wasn't for me and ended as a major disappointment. It also feels like the author massively changed the tone later on due to complaints for some reason, which may be why disliked it. I genuinely feel frustration after reading it, so I don't recommend it. <<less

I think this book is good but not for those who don't have any Patience. On the start, they have obvious misgivings bit then they get better once you get to chapter 4-5. Although his skills may seem bad at first, it plays a huge advantage just like his nobility. His family can be like that only because of their low status. Anyway, this is good for those with patience.

as someone else mentioned, I think this is a novel aimed more at tweens or younger teenagers with tons of wish fulfillment and lots of super specialness for the MC. Though the MC says he wants to keep things low key and get strong in secret he begins showing off as soon as he gets back the first time. He's also incredibly thick and nieve, which is why I think (hope) the story is aimed at kids. I would have enjoyed this story at 13 even if it is a... more>> harem. As an adult reading it, I find the MC extremely frustrating and his behavior senseless and contradictory. Recommended for those younger kids or for people who love idiot MC/ isekei build for their MC (despite not transferring from another world, his behavior is almost identical to the isekei harem novel MC). Lots of contradictions and plot holes already and I'm so irritated by chapter ten that I am dropping the story. <<less

The story is kinder basic if I was being honest from shameless, secretive MC to the childhood promise. The thing that really lets me down is the fact that the MC has a creation skill actually means nothing, sure he did become stronger but still for someone​ who has a creation skill is still weak. The MC also has no understanding of danger when it comes to boasting or trust. On a whole for someone​who has been suffering as beggar noble has no concept of low-key. Really an utter disappointment

Harem virgin bait novel. The MC is very child like (no surprise its a novel for young teens/tweens) and the author is obviously pandering to the chuunibyou virgin crowd. Its a lighthearted read that really has no drama or overly mature themes besides the pubescent and sometimes incestuous and pedo like innuendos and physical contact but even they are mostly not very serious. That's not to say you cant try and find deeper meaning to what's going on just that you are not supposed to.

If you are younger give it... more>> a shot you will probably have a fun time.

If you are older and want to read it just know you will have to make some concessions with logic and reasoning. This is defiantly not for you but if you can let the weird and illogical parts slide you may enjoy it as well. Individual mileage will vary. As an older reader myself its just not interesting enough for me but that doesn't mean I think its bad. <<less

MC is beta af, waste lp for weakening each enemy instead of strengthening himself, cant sell rare items because doesn't want to standout but let entire guild know his master is olivia and he inherited OP skills.

his sister almost get roofied by phantom grass dealer and probbly going to get r*ped, but he only, literally smack the guy with wooden sword and give warning. Didnt even kill or atleast report to guards.

lot of forced plot, and after chpter 143, I dont think the story will develop. Lot of useless characters,... more>> no backgrpund stories on characters.

read-able from c1-c40, after that just a lot of donkey writing, JUST DROP this. I nvr cmmnted or leave review on this website, but because pure s*upidity of story and MC I have to warn the next readers, please save don't kill few brain cells for this ****. <<less

If I can give this novel a 4.5, I will but you can only choose whole numbers. So I rounded to the nearest whole number. It a good story to read if you want some laughs and light read. But I don’t recommended it to people who wants a story that is done right on many points. This story is just for people who wants to chill and see most of the things probably go the MC’s way. Also, this is probably the author’s first couple of tries to write... more>> a web novel series, so please don’t be too harsh on the rating. You can see it if you read a little more carefully. Just don’t be a douche and say that it is extremely lacking. Also, this will be updated as new chapter is released. Rating not actually solidified. <<less

Ok, so I'll keep it brief.

The level system is useless. You can kill level 200+ monsters while being level 30 or so.
MC is tr*sh. Got the strongest skills, but doesn't use them properly.

This is why I gave it a 1-star review (chapter 130) :

Some guys tried to r*pe his sister. They forced her to enter a bar in a alleyway and wanted to drug her.
What happened? He went to his house like nothing happened. No warning, no beheading, no nothing.

Can't believe I made it to chapter 50. Even for teenagers this is terrible. The MC is beyond dense in every way possible. This feels like it was written by a preteen. He gets the ability to edit/create skills and grant them to others. It costs LP to do so. He constantly uses his LP in the worst way imaginable instead of simply strengthening himself. Sure. Spend thousands of LP giving your opponents debuffs specific to that opponent and situation, instead of simply spending a few hundred on yourself to... more>> get some awesome skills. Makes perfect sense. The few skills he's bought so far have been fairly cheap too. An example, he could spend 1000lp to increase the range of his lightning spell to 10 meters, he needs to use lightning because it's an earth dragons weakness. Instead of zapping the sleeping dragon and running, he hides, about ten meters away, and spends 1000 lp to charge a piece of meat with lightning to use as bait. A one time use item. Almost every fight is like that. Typical Japanese beta MC. Surrounding a 16 year old with girls that wanna screw his brains out and the MC being too dense/beta to actually do it? I'd rather just not have to read the harem crap at all, it's way way too unrealistic. No matter what world/setting it is. No teenage boy is that nice/dense. <<less

A perfectly adequate story for killing time and brain cells when you have nothing better to do.

Look, not all Light Novels are going to be great works of literature. This story is *definitely* one of the ones that aren't, but for all that it's still a lighthearted, fun, unserious story. This is the kind of story that sees absolutely nothing wrong with giving the main character skills that are recharged by kissing - but at the same time doesn't take itself seriously enough to turn itself into a R-18 p*rn... more>> quest. It's s*upid, mildly perverted fun in the way that many Japanese LNs are - there's not much to elevate it from the pack, but it's not egregiously bad either. <<less

The MC is about 1 part Chad, 2 parts b*tch, and 2 parts pussy. He makes out with girls and touches them without hesitation, but he always makes sure to make it known that he's doing it because of his skills. He only made out with the FL because it's the only way he can use his skill. He only felt that girls ass to get stronger. He only kisses and hugs his sister and mother because it's Japan.

The WN is 5/10, the manga is 1/10, the anime is 3/10.

i like the level headed MC, not overly edgy.. And not to forget to humble, can do lewd things w/o overly excessive.. Coming here from manga.. And people read and give your honest opinion based on the genre because not everything had to be arifureta or mushoku tensei.. Or any gungho over the top chineese novel

unfortunately this site is filled with critics with overtly high expectations with way too much free time on their hands so don't believe all the 2-1 star reviews below. Hell go look at their other reviews and you can just see how bad they rate other novels. Anyway now that that's out of the way I'll get on with the review the story has a lot of common troupes but it's fairly interesting with likable heroines a decent MC and overall nice comedy with good slice/life moments. Of course it's... more>> not for everyone especially those who aren't very fond of troupes but in the end I suggest you give it a try and see if you'll like it yourself and don't listen to what other people have to say about it including myself you will either hate this series or like it. There's also a manga and anime adaption so try those out since they give more visuals to what's going on in the series. <<less
