Description

Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

A world where the [Demon King] was defeated by a [Hero] that came from another world. People carelessly forgot about their fear of the [Demon King] and of monsters, living in peace.

In a forgotten and run-down cave in the mountains, a new monster that should not have been born was given birth.

The monster’s name was the [Black Ooze]. It was nothing exceptional other than its black color, an ordinary slime.

However, this slime had the special characteristic of being able to take the abilities of the living things it swallowed. It preyed on an insect that had paralytic poison, as well as other animals. Following that, it attacked a human, obtaining his knowledge and [Desire].

Before long, the monster established its target as the female mage that came to explore the cave.

This world still wasn’t aware.

[A Monster Was Born]…

I think the brilliant part of this novel is that the entire story is written in 3rd person perspective. It's like you are watching a horror-p*rno movie and just see how these tent**les capture its preys, makes them climax, makes them breed and possibly break their minds. And you are just sitting here, watch them suffering and occasionally j**king off.

So yeah, it's quite interesting and novel. You probably won't finds similar experience in other R18 LN/WN so why don't give it a try if you are lacking of m**turbate materials.

Also,... more>> story is getting better since Vol.3. <<less

Honestly, the concept is very interesting, and it is somewhat well done but... It became boring. Ever since the start of v3c1 it feels like there is almost no progress. I find myself skipping multiple paragraphs for they have absolute no meaning.

However, I will keep going, as there is some development every once in a while...

Much like everyone who said it was good, I would say the same.

Only that the word of choices seems lacking, but perhaps, that wasn't the author fault. Just probably translators unable to think a better way describing the situation in "English".

I am giving it Four because of translation. In case where the translator has become better, Let's make that as Five.

80% slime tentacle r*pe and mind break, described in great detail. Mashed into the rest are decent character development (for the genre, at least), good world building (given the space it's got), some story development and the underlying possibility of a deeper plot unraveling at some point in the future.

Prety good read, it balances the gap material with the plot pretty well. Honestly though I can only see this going one of three ways: either the slime grows intelligence and stops mindlessly reproducing let’s be real not happening anytime soon. Or it kills and r*pes everything and destroys the world, or lastly the nations rise up and kill the slime whil becoming more vigilant to new threats being born

Honestly no one expected a good plot from ero novel, but after several volumes I became pretty annoyed with perfect hero who saves everyone with the power of bullsh*t every time despite this being supposedly "bad end" title.

Zing translations made the whole detail and plot of the whole story progress pretty good. Well the only thing is that it's NSFW and weirdest fetish make it all up. Might be recommended only for big readers that just reads almost anything.
