The Stubborn Skill-Grinder In A Time Loop by X-RHODEN-X

I won't address your opinions on the system and and the power system, because they are your opinions and you are entitled to them, I will talk about the rest.
This story is not a parody, the only 'funny' parts about the story are the narrator and the side characters' comments on the MC's stubborness, and those are kept to a minimum. There is nothing Ironic about a man dying hundreds of thousands of times, unable to form any meaningful connection with other living beings, feeling both physical and psychological pain during and after any relativly long loop, something that you would know if you read further (Blue fire Academy arc, Novarria arc, especially the latter with chapter 44)

First thing that starts to hurt my eyes are dialogue and characters.
They are indeed incredibly constant, and even that are carbon cut-outs many times over, they are not ones that you expect, to see. I honestly don't understand what you are trying to say here, that the dialogues and characters are boring?

But the problem is that the don't speak. they "Convey intension and information"
What is, the thing that allows to make the book, so absurdly fast passed.
But it also make it fully emotionless too.
I believe that you are referring to the time skip during his stay in the Guzuhar, since that's the furthest you have read. The fact that the author glossed over the months he stayed in the other continent is beacuse there really wasn't much to tell about the characters that lived there; yes the Author could have told us more about his stay, but ultimetly the only reason he went to Guzuhar was to find a way to hide his fate, the relationship he had with the continent natives was almost entirely transactional, except the affair he had with the girl he did not build any meaningful connection to write about there, he basically only trained.

World is... generic as it gets. Once again this is also your opinion, based on incomplete information, but you can think what you want.

He is stupid. That's the main point I suppose, as that even written in the synopsis.
He is extremely stubborn and not very prone to change his way of fighting, but he is not stupid.

And he is also not very determined. You may argue with me, but he is just stubbornly chase after a set goal. But he have no will other then that. Someone with less willpower than him would have broken down entirely if forced to go through what he went through, he did not remain sane after dying an uncountable amount of times just thanks to stubborness. Also you can't say that he only has willpower when chasing he is after a certain goal and not when he isn't when there was never a time in which he was aimless, yes at times the goal was foggy and not easly determinable, but it was always there.

He have very basic moral, that I have no idea where is from in him, but whatever.
His moral compass is indeed not very defined int the first twenty or so chapters, but again this is a 'you' problem as his morals and ehtics are shown when he visits the dwarf kingdom, a part of the story you did not read.

Everyone says how cool he is for dying a hundred thousand times to get resistance skills, buy really, even before that he had at least Pain resistance 20. And really, since he dies in the battle, with all the adrenalin, it is really not that bad. It has been shown in the story that his pain resistance skill means nothing if the pain exceeds the skills' limit, that will cause him to feel actual pain that he has to actively to endure with his willpower, causing the skill to level up. Why are you mentioning adrenaline in a world of Swords and Magic that clearly dosen't work on science? What is adrenaline going to do if he gets his soul damaged, or his consciousness gets attacked?

And well, it cannot be, proper criticism, but the fact that skills, blessing, just go in time with him, without any effort... Is just infuriate me further. And amount of absurd rarity skills, make it even worse. This is why I asked you if read the story properly, beacuse if you did you would know that most, if not all of his active skills and even many of is passives are the resault of heavy training and or 'enlightenment'. The system does not give free stuff, not this one at least. As for the blessings, he can't do anything about it,

PS

I could not give a flying f#ck about your hopes on me, so keep them to yourself, and the questions
how much of the story did you actually read? and "How far have you reached into "regressors tale of cultivation"?" may be worded differently but posses the same meaning, they are just referring to different novels.
