Only the dungeon part is barely acceptable. Everything else is terrible and plot goes wherever it wants. The protagonist also makes illogical descisions on multiple occasions...
The first 20 chapters are really good, especially the mc's golden finger, but 20-90 are almost completely filler.. no progress whatsoever. 2 stars
update (-1 star): chapter 108 still a spirit grandamaster but he has started sparring with dugubo. bro is gonna be invincible when he gets third spirit ring. dissapointing :(
The idea is very good but the story progresses so rapidly. He got 3 spirit rings in 15 chapters. His ability also get overpowered very quickly. Overall a wish fulfilment novel
