At the start of the story, the MC is on his SECOND isekai adventure. He was summoned to a different world before the story began, lived as an SSS-RANK warrior/adventurer, then returned to korea with his powers sealed, and then lived a normal life. Then the story (that we are reading) starts, and he is summoned by someone he knows but isn't friends with to a different world. That person tries to use him as a sacrifice but it backfires because his soul is stronger than the summoner's due to his previous isekai experience. His previous powers are NOT unlocked, but instead he is given the role of a psuedo-apprentience dungeon master with the ability to tame monsters if certain conditions are met. His goal is to essentially conquer the labrynth so he can become its master (maybe?) by subjugating the labrynths inhabitants. But to be clear: he isn't a demon lord, the labrynth is not under his control and nothing is intrinsically friendly to him. There are monsters that are non-aggressive and seemingly neutral, but everything in the dungeon has its own free and can resist the mc's power. These monsters are not mindless npcs. As a seemingly regular human, he has to tame his way through the dungeon to win like some kind of single player game. But because he has previous isekai knowledge he has a fundemental understanding of the situation (knows monster ranks, strengths, habits, weaknesses ect) and decides to just go with the flow until he can find some humans or monsters that know dimension magic so he can go back to korea (presumably how he got back the first time). He is given a set of powers, which primarily involves taming monsters. The second part is to ask for help from humans on earth. He gets a game interface, which is a normal function of the isekai world's setting but is rarely seen. The natives consider it to be divine inspiration for special people, the average person cant see it. And the MC didn't personally see this on his first trip either, but he does see it on his second trip which is why the author explains it in such a round about way.

The second part of his powers is the ability to host an interdimensional livestream. Strangly, his streaming is limited to random people on his earth mobile phone contact list. He is allowed to send out invites that last 24 hours and if they agree to help him, they get to watch his adventure as a live stream. They can chat with him and then spend real money to send him items and stuff. Just 35$ for a loaf of bread! As a consequence of this setting, he is ALONE in the dungeon, but at the same time he has an active audience cheering him on as stream-chat and providing commentary.

its implied that the labrynth is not a normal terrestrial dungeon but rather a very special dimension that attracts and contains the multiverse's strongest entities. The highest level monsters populate the dungeon, and occasionally heroes and villians from various worlds get summoned into it by unknown mechanisms. These people are called drifters and they are free to do wahtever they want once entering the dungeon. This dungeon is seemingly the main source of all gate/rift type events in the multiverse, which means occasionally rifts will appear and the monsters will be summoned away and go on their own little side stories. Later on, the MC can deploy monsters himself to other dimensions, and there are many alternate dimenions. The author is really ambitous with his world building.

the wandering merchant sells s*x toys. s*x toys for men and women. s*x toys that strangely provide buffs, and s*x toys that can be EATEN which allows the user to grow reproductive organs. It's the first item that the merhcant introduces, and at face value it feels really weird to read. The main problem this author has, is he introduces concepts he's already planned out in his head first, then realizes the reader doesnt understand whats going on and begrudgingly explains the reasoning afterwards in a seemingly random and disconnected fashion. Why is the dungeon merchant selling edible d*ck growing s*x toys? Because the dungeon wants to grow. It uses desire to expand it's bondaries and create new monsters. It encourages the humans it steals to reproduce with themselves and with the monsters that populate it in order to create new hybrid monsters. The kind of people it snatches up to play its death game usually have some kind of weird hobby or quirk that it can exploit to achieve this, and the explorer's gifted powers are reflected by this.

The MC is an exception to this concept, because he wasn't summoned by the dungeon but rather was summoned indirectly by a dungeon explorer who then died while coincidently being the last explorer of his group which resulted in the dungeon being forced to conscript the MC. So the MC is, by all means, a 'normal' person, and not the kind of person the dungeon is suppose to appeal to.

So who is it suppose to appeal to? The first example we are introduced to is a female tamer of the previous generation: a previous female explorer who could only activate their taming powers by having physical relations with monsters. What? That's right: She had to have s*x with them, which resulted in her giving birth to monster hybrids. The first time you hear this, it feels random and nonsensical, even the MC starts to get a little creeped out. The MC is given her journal where she spells it all out. How she secretly always wanted to have s*x with non-human creatures and is having the time of her life living in the dungeon banging male-monsters. In comparison, the MC only has to touch the monster to tame it.

Another previous explorer gained powers by eating monster parts... specifically monster poop. Had the MC chosen the same skilltree, he would have only had to eat body parts which seems much more normal in comparison.

Much later in the story, it's revealed that this dungeon is essentially the creation place for a lot of monster species. It farms sentients throughout the multiverse and tricks them into helping it create new life. Eventually, new born/evolved monsters start calling the MC 'daddy' as he gains more control over the dungeon. Coincidently... he seems to only attract female viewers... and the system specifically calls them... assistants. not viewers. assistants. Assist him with what ;) The MC starts to put 2 and 2 together and realize this dungeon seems to be powered by 'desire' and uses explorers to 'grow' and starts to question his life choices... will this concept go somewhere intellegent? It's hard to say, the author seems to be riding a fine line between what is acceptable and what would be considered really niche tastes. Our MC doesn't seem keen to get involved in these kinds of shenanigans... but seemingly every other character is
