I think you mean novel.
Here it is https://deroxzone.com/serie/the-artist-who-paints-dungeon
200+ free chapters and 200+ chapters that have to be paid for if you want to read them early (or just wait until the release dates for them) so 400+ chapters in total

Honestly, the manhwa does a good job conveying the emotions from the novel however it’s way to fast paced compared to the novel. The manhwa didn’t skip some important details but more small moments like the creation of the blue birds and honey, and the closeness between the MC and white hair guy.
There was a scene I was hoping I would see where the white hair guy thought MC was upset be I he didn’t come out in days but he was just drawing the blue birds.
The novel is more cozy and it goes into a lot of detail about MC and his life in the painting, but it seems like the manhwa might just be action or adventure ish since most of the cozy scenes are being taken off.
Not hating tho! I like both! But it just a tad bit disappointing ┗( T﹏T )┛
