@ocdmn not really.. artstyle will change subtly as more chapters came out, but i didnt notice any drastic changes from last chapters other than the atmosphere from the environment

There was a 1 page notice on the Chinese Manhua site from where we get chinese raw, that We are lacking manpower so can't post chapter today. So probably they took in new artist to draw but with same art style, things might be a bit different with different artist.
Someone told me that the author of this story gets bored and rushes the ending leaving a lot of lose ends unexplained. Pretty sure you never find out what he gave the nether lord because it was forgotten before the ending but I really hope I have heard wrong and the author didn't give up.
