Many dungeons suddenly appeared all around the world.

It was the era in which both civilians and the army were exploring the dungeon as ‶Seeker″, and brought back the miraculous items with them.

On a certain day, Mitaka Yuuma [2nd Year High School Student] whose life had nothing to do with a dungeon found a hole in the corner of the garden of his house. When he tried to peek into the hole, he found a metal body trembling non-stop inside the hole.

At first, he had no idea about the hole he found but knew that the trembling metal body he found was a monster called metal slime that had become the current hottest topic in the world.

「Could it be that this hole is actually, a dungeon?」 was the conclusion that he came with thus, began the change of his daily life, coming into the dungeon hole and beating the metal slime.

I read ahead with MTL. This story has the same usual flaws as other JP fantasy novels, but with a masochistic twist...

Short version: It's a story about a selfless beta male making bad decisions and getting sh*t on for saving lives. As of chapter 171 basically NOTHING GOOD has happened to this guy.

Spoiler

Chapter 171 started human experimentation...

[collapse]

I gave it a shot, I thought it would get better once they finished the first few arcs, but it's only getting worse. Save yourself some frustration and avoid this story.

Honestly the story isn't any good the MC anyways compares himself with his friend from childhood. He's effectively Ron from the 4th Harry Potter movie before he realized that someone was trying to kill Harry only he hasn't said what he feels. The only reason it's a 2 star instead of a 1 star is that the site is convenient with a dark mode and the next chapter button is readily available.

First arc (everyday sliming) is ok. Slow progress but enjoyable. MC tried his ideas and got results.

Second arc (job hunting and beginning of dungeoning) MC just doesn't use his brain. He has no idea, no initiative, doesn't evaluate himself and stopped trying things unlike his garden dungeon days. He's just very different from the first arc and it's frustrating to read. Still, the story progress is interesting enough for me to keep reading.

I really enjoy this, though I question some of the logic used by the government and the MC's allies. The biggest hurdle for me...

Is that the MC is just a powered up human but soooo many, including other "seekers" (what this series calls hunters/adventurers) who have been powered up with literal magic dont just treat him as a monster but are incapable of seeing him as anything but a monster.

[collapse]

That said, the limits on the MC's powers are quite interesting and it's very enjoyable seeing him acquire new powers and allies. I read all the currently translated chapters and couldn't stop there and read all the Japanese chapters available.

The most frustrating thing for me is that there's not more to read yet! <<less

I think this is a good story to pass time, a bit of anticipation was presented when I read this chapter, but I think it will be fast once it hit chapter 70 or 80. It's a slow pace at the start, some premonitions were presented there.

I enjoy reading this so far.

So far I like this story. A bit of a slow start with an underachiever unsure of his place in the world. I would like the supporting characters to fill the story a little more. Other than that it’s an easy read that feels like a good buildup is coming. I’ll just wait and see.

Overall pleasant read, it is very good story in first two arcs (up to c54), but after that it starts to fall apart. After 3rd arc I started to think that author lost this idea for story and in 4rd and 5th it's obvious that MC is hella dumb and does idiotic things just for story to progress in some way.

Heavy spilter:

Biggest problem I see is that since killing deca slime (black king) he didn't colored mana (apart from black). Then in just for preparation his boss bought 350 blue mana and then after some grinding (one dive) he gained additional 150... And this was in a span on 1 year! Then just to fix MC before Red king they gave him enormous amount of blue gems...
