Writing this because I see people complaining everywhere that the protag is a "p*ssy" and want to clear that up.
The protagonist's character progression is amazing. He lived a peaceful life growing up so it would make no sense if he ran around murdering everything in his path immediately unless he's a total psycho. There is nothing unique about being a horrible person; you can just read xianxia if you want to see that and you can easily find enough to read until you're sick of it.
Instead of just being a sociopath, the protagonist is a person with a good heart who is slowly dragged into the violence of the murim. For the first part of the story, his power is enough to allow him to keep his hands relatively clean, but as he meets stronger enemies it gets harder for him and he's forced to adjust psychologically.
I don't know why tf someone even said he acts like "with great power comes great responsibility" because he does nothing of the sort. The protagonist thinks everyone has the responsibility to not be a !@#$ing serial killer regardless of power level and that's entirely reasonable. He personally helps people when he wants to, which is often, because he comes off as a genuinely nice person, but he puts his personal goals first (which are not nice at all). That is not something to write off, because the reason a lot of generic "good" protagonists are annoying is that they're actually unsympathetic hypocrites.
And no, him being a nice person does not make him "boring" because he is constantly forced by the plot to have to make decisions where he can't accomplish his goals while being "soft". The internal struggle and resulting brutality is much more interesting to watch than "hurr durr I instantly kill everything that pisses me off because I'm a reincarnated dragon bloodline asura god of destruction". The people complaining that he's not OP enough are probably in the middle of their isekai addiction phase.
As for the landscape panels: They are amazingly detailed to the point where the artist is some sort of miracle worker for being able to draw so many of them in a week. They're just plain gorgeous. The fights are cool and the humor is good. The side characters are good, too. Overall, one of my top 3 webtoons.
