I really gave it a try, but it's just not very good.

The story has him in a dungeon that you have to clear solo. That already makes it rough because there's no group to play off of, no other characters, it's just chapter after chapter of him talking to himself. It gets old pretty fast. For the story, he chose Hell difficulty so the levels are very dangerous and the traps do lots of hits and damage... but that means he levels up crazy fast in the first dozen chapters. The usual instantly OP isekai stuff, sigh.

But it's not even entertaining. I got over two dozen chapters in and there hasn't been a single fight yet. It's just him deliberately taking hits from automatic traps over and over to raise his stats and talking to himself. No other players to talk to, no monsters to fight, just one guy walking into arrow traps over and over and talking to himself.

Look, it's not terrible. But like I said, it's just not very good. There are a lot of 9/10 and 10/10 manhwa to read, why settle for a thoroughly average 5/10?
