Small upgrade system

The concept behind the story itself is good. But the mc is shown practically as machine whose only job is to eat, sleep, train and dungeon run.. and close to no human interaction.
Writing quality is average to say the least as many grammatical mistakes and wrong usage to words can be seen.
well, for story development there is nothing of a story only a sort summary of his background and what is now then he just goes around training and dungeon running with no human or world interaction...
Character design. . .   well, at least the characters that author had given importance to are well described and designed but later in story i got the feeling that the story is all about mc dungeon running with no outside interaction.
update stability..  .i don't know about this...  
World background well, it is well described but as we progress only mc's home, motel and dungeon becomes readers world because nothing is told or happens with mc in relation to that.

So in short if you want to read a novel where mc just focuses on getting stronger with nothing else in mind then go ahead.   
(well, after many chapters some world opening happens with mc but still it can be considered negligible interaction with outer world)

Hi, the author here. It's my first novel guys. I am pretty inexperienced about but I will try to become better at this. I hope you will enjoy this novel.

This is amazing, I’m absolutely loving this and it’s quickly become one of my favorites. I have zero complaints except for grammar and I don’t even really care about that. Can’t wait to see where the story goes, excited for the next chapter!

read 40s chap , i like this kind of novel, in some area its become repetitive story thats whats the slow paced novel problem is, i like the mc act like a normal people , easy to read, im bored of those arogant novel, so this one is fresh novel for me , i will read some more-

My guess is all the bad reviews are deleted, cause this is not great. It’ not a bad premise, but very definitely not small upgrades. The writing quality is grade school level, or non native English speaker level

The story has a lot of potential, it is a great idea, but unfortunately has terrible execution. The fighting is explained terribly and the author makes a lot of mistakes, he forgets what he has written already, and English is clearly not his first language
