Not your typical dungeon

Reviewed at: Chapter 62

Prime Directive: Make anti-mana

A different take on a dungeon tale. Our MC is a core who is able to have minions leave the dungeon, he is miles ahead technology-wise when compared to the surrounding kingdoms. But woefully incompetent with people skills.


Let the hilarity begin!

Adsterhappy always makes me happy :D

-The style is fantastic, and while it represents a machine and co. well, it could use more litRPG elements to represent the litRPG tag. After all, the beggining represents that but it can also just be a normal system interface, as there is no menu. Though the upgrade paths fix more of this problem, and if the recently included system pays off well it might become a five star.

-The story is how you think they would react, but at the same time throwing in suprises here and there. There are always advancements that keep you entertained and yet there is enough tension because sometimes you aren't always supporting the MC due to ruthless actions. A fantastic balance!

-Grammer problems- 0% detected. Cleanse: Unnecessary

-The characters always have building to them. While Custodian might not have a fast developing character, those around him develope quickly. The enemies, when you see their point of view, actually seem like people. Sometimes you cringe a little when you see the people you kinda liked fall. Adds emotion to a (currently) quite emotionless MC

Overall everything is great, and if the Foreman thing gets developed further (currently i'm at chapter 35) then a five stars for style too!

excellent dungeon story

I have read many of the dungeon novels on Royal Road and this is one of the best ones in my opinion. It is the only sci-fi-ish dungeon novel I have truely enjoyed.

Ch 49

Read all of this in one sitting 

I am biased towards dungeon novels but I didn't see anything annoying 

I hope the author keeps writing 

Update ch 70

I still enjoy this story

Amazing character development, story flows well.

This might just be my new favourite story on here. It is an incredibly unique take on the concept of a dungeon core novel.

The story flows well and doesn't get stale. I find the style to be very nice to read.

There are a few errors in the grammar. There aren't many and they don't take away from they story, but they are noticeable. Think about a plural instead of a singular, or an extra 'the' in a sentence, nothing as egregious as there/their/they're or similar errors.

If I could give a 6 for characters I would. The author manages to very naturally develop the drones that the MC starts with by showing instead of telling how they change. The drones also feel like different people instead of different clichés.

All in all I definitely would definitely recommend this novel to anyone.

Maybe cause I was sick

I was not really feeling all that good when I started reading the story and even when I felt better the story just feels so lacking. I only made it to Chapter 11.

The story in my eyes has some serious fundemental flaws. Super computer AI that has feelings but dosen't but does; you think that this would be a highly powerful 'go-getter' from the onset, but it is like getting a child's Leapfrog when looking for a state of the art mega server.

The Dungeon Core thinks and acts like a normal person, if you wanna take it a step up or down you could say it is a person with a mild form of OCD.

They story does however pick up after the 7th chapter; or so it did for me, but at that point the dungeon story I was looking for had aleady burnt the bridge.

They story up to that point is not really bad persay, it is just not what was advertised - the story as of ch.11 is about the life and times of semi sentient worker drones that learn to take care of a fubling 'sentient' calculator, and that is actually a decent story. if you are looking for it.

I like the idea of a the author about the mc and his ilk and how they interact with each other, a detailed story on how they got their names, details on the daily operations the mc is doing for his/her one goal, whilst keeping us reader in the dark on how they came to be or who made them, and what their agenda is. This novel is both fresh and entertaining Great job!!

incredibly fascinating and marvelous

So good you'll look up synonyms for amazing to put in your review

It might be because this type of fiction is right up my alleyway but I absolutely adore this story. I wait with baited breath for each new chapter, jampacked with action and intrigue.  The characters are well developed and the world grows and is revealed in a pleasing and organic way.  Try a few chapters, you won't regret it.

It's so good I coudn't stop reading for 10 hours

If you like logical inhuman powerful protagonist, this is the jam for you. It's a masterful introspection into a semi-alien mind, with good plots showing up everywhere. And the pacing... HNNNNG the pacing feels GOOD. Good job author.

First of all my English is not native so will have errors. Finally I found a novel which I liked was the "exterminator Dungeon" to everyone who still has doubts about starting this novel, you can trust me. They will not regret, because every chapter at least for me will make you read until the current arrives so good that she is!
