yes

There seems to be a problem here. The Main Character, Jintao, lived on our Earth where he read 'Reincarnator' and then reincarnated on an alternate Earth of 'Reincarnator'. That's about it for the reincarnation. And if people don't know these two worlds, then it isn't really my problem. I don't know why the MC should have been in the Reverend Insanity world when it's a fanfic of 'Reincarnator'...

There might a mission for being the last survivor, but the way Fairies operate, they wouldn't reward it to someone in a situation where he simply survived by hiding around. I will explore how the missions work in the future (at least my interpretation). And, given the advantage of the first day due to the Gangnam station, the MC would grow at a much faster rate to easily crush everyone in his tutorial zone anyway, if he wanted to kill them; it's inevitable even if he didn't have any traits or plot armor.

Jintao's goal is complete supremacy, so he would naturally do what's the most beneficial to him. Tutorial stuff is a small matter, but afterwards all the good stuff comes up almost only due to Hansoo's actions, so following him for a time is a given to ultimately kill him and take his stuff once he loses usefulness, since he's simply a dangerous competition with similar ambitions of becoming a Demon King. Jintao going his own way would only cause him to lag behind and miss opportunities, so it isn't feasible, unless the story took place during Hansoo's first visit in the Otherworld. But in that situation Jintao would just stumble about through the zones (after crushing the tutorial), since the colorodez zones are in too much mess to conquer without future cheats and there's too little time for him to grow before the Abyss.

Not at all. A very logical and natural thought for someone with his ambitions and mindset

It is that in this chaotic situation with goblins pouring in from one direction and a weak target nearby, killing her and taking away her dagger is the best move. Since there's a decent chance that the rune might be an Agility or Perception rune that'd increase his survival chances and potential benefits.

Well, Hansoo is like a machine, constantly hunting and constantly rushing forward with no sleep, like a juggernaut. It's really cool and I enjoyed reading it. The world building there is good too. It's just that the translation makes it hard to read and there are also other problems with it. And then around chapter 300 the novel takes an 180 turn in the story (Imo ruining it) and the translation quality drops even more; it's to the point that I instantly dropped it the first time I read it. But early on it's an amazing read. Most of the negative reviews are due to the translation and the twist in the story. But even if it's about reading it until the half-way point, I would still recommend people to read it. It's like with RI, unfinished, but it doesn't matter.

I'll use your comments to try to make things clearer then.

There are many tense situations where everyone's life is on the line and he needs people to cooperate with him, so these kind of reputation is necessary for him.

Ah, maybe you are a bit biased after reading only the pieces here, but Hansoo is actually a really great antihero MC. He's forbidden from killing humans, but he would still use pawns to secretly kill troublesome people in his stead and he would kill them if they are bound to die anyway and no one would find out about it. He's probably the best antihero there is, in the first half of the novel. But yeah, the original novel has certain parts to it that makes it kind of trash, even though I like it for other reasons, so I'd try to correct the flaws in my fanfic. The way Hansoo is forced to act sometimes is also a bit annoying, even though it's always logical.

Yeah, but the Otherworld is only a single part of that world. Humans are competitors there, but after that they would be sent to the Abyss, where the humanity would face against various higher races like the Demons and Dragons. Because of this kind of internal fighting over the years in the Otherworld the humanity basically went extinct and couldn't put up a good fight, and that's why the MC tries to change things with him as the center.

It sounds quite wasteful and stupid in the moment, but it isn't that Hansoo isn't willing to kill humans, but he forces himself to do things like this for his long-term goals. He has a grand plan of uniting the entire human race and looking long-term it works out well for him, since later there would be many rumors of him never killing humans and people trust him thanks to this. Also, he has the confidence to become strong while doing this, so it doesn't hinder him.

There are 200 goblins in total. No matter how you look at it, rushing in to face them first doesn't sound like a safe idea unless one fought against them before. The MC waits for the pressure to lessen first, and he also knows the way to get stronger afterwards, so he doesn't need to desperately fight for every point if there are risks involved.

The first point gives a large boost, but then Perception has progressively harsher diminishing returns. The MC will explore things like this over time. One reason is because normally humans have no Perception stat, so the first one gained gives a large difference.

A bit of a spoiler: At the start the MC has short hair, since he was momentarily in the army, but later he would grow it out like on the cover due to a skill. His tatooes migh also be a result of a skill.

Yes, I'll upload a new chapter soon, as I'm rewriting it right now. It's only that since I want to make things good, I'm still drawing a draft and writing ahead.

I removed it because I am not sure how the story will develop in the future and because it is not harem focused.

There will probably be some. Stop asking, man.
