I've read the prologue and the 1st chapter, the art looks promising, the story is simple tho but it's less corny than other dungeon themed manhwas. Reincarnation of Suicidal Battle God is still much superior dungeon manhwa story-wise, but the art is similarly good.
Don't fall for "Return of Disaster-Class Hero" tho. The art is good since the studio is the same that made Solo Leveling...but it's a trap. It's just filled with Edgelord tryhard MC who face no challenge at all in his fights and plot...and side characters who worship that MC. Lolol
