I also can't say that I've read a huge amount, but the other current reviews only read to chapter 12, and I'm on 29 (and this is probably where I'm going to stop reading it, too).
This story isn't terrible, but it's also not good. It doesn't feel like its own story; it's more generic and a bit of a cash grab by the author.
Translation: near perfect, I have no complaints. I think I only noticed one editing mistake, and the actual quality of the translation is quite good.
World-building: Ok, but not incredible.
Character-building: Not far enough in the story to give a definite answer, but it doesn't feel like the MC is going to get much growth, and side characters feel generic and unimportant.
Story:
The story so far doesn't really feel well defined and doesn't currently show any intention in doing so, in my opinion. The MC has no real motive for growing stronger, not even a basic reason like survival. He's just living his life in a city, hanging out in his master's old temple. Power progression is extremely vague. More concerning is that there appears to be no real struggle, at least for now. If it had better defined characters, I wouldn't mind the lack of direction, but the story just doesn't feel like it's going anywhere.
The MC hasn't done anything to catch my interest. He is effectively being handed everything by a mediocre work ethic and a merit system (which sounds like it might not be just him who has it based on how they described it, but I dont really know because it wasn't described well). He has effectively gained like dozens of years of martial arts cultivation in what seems to be a matter of days. It's one of those novels where it's like "it's said that practitioners of this skill will take 20 years to master this" -> "Oh cool, I did it!"
Personal Gripe:
Also, in the first 10 to 15 chapters, with how much the author describes the appearance of the innkeeper, it feels like he was writing this story with one hand, if you catch my drift.
