Description

Thrown overboard into a storm, he should have died.

Instead, he wakes in the abyss, reborn in a body that isn’t human.

A system pulses through his skull:

[Unit Registered: Biomass Anomaly][Insufficient Biomass to Evolve]

To survive, he must feed.

Every kill grants biomass. Every evolution reshapes him into something less human. The deeper he descends, the more the rules tighten, predators hunt by signal, ecosystems react, and the system itself begins to push back.

Growth is not free.Abundance becomes a trap.And the more he evolves, the less control he has over what he’s becoming.

From the crushing dark of the ocean to something far beyond it, he climbs—predator, weapon, participant in a system that rewards obedience and punishes resistance.

And when survival demands not just feeding, but enforcing the system on others…

What remains of him?

The sea gives. The sea takes.

From Abyss to Cosmosis a dark LitRPG evolution story featuring:

Monster evolution and non-human progression

A ruthless, system-driven world

Psychological and moral descent

Slow-burn power growth with real consequences

For readers who enjoy darker progression fantasy where power comes at a cost, and survival means becoming something else.

From Abyss to Cosmos is a stellar read - It grips you with vivid imagery and high stakes from the very beginning. I've read up to the current chapter, 27 in a day, I really couldn't put it down.
Big fan of the psychological aspect of the story, as we begin to question how much of the MC's humanity remains as he slowly climbs the sea food chain - you question the morality of his actions, which is mental because he's literally a fish.
All in all a very enjoyable story and recommended.

Is this a rewrite? I could have sworn I already read most of this and more in a different story by the same name?? Also if you are going to be using ai in any form then you need to tell the readers what exactly you are using ai for-are you using it just for spelling and grammar purposes or are you using it to generate small or significant portions of the story-or even the whole story! I refuse to engage with anything that doesn’t explicitly state what they’re using ai for because who wants to read something that the author doesn’t even care about enough to write it themselves

TLDR: Just read the title, it basically sums up my feelings and my gripe with this story...
I initially suspended my disbelief after reading other reviews mentioning the use of AI. I wanted to give the author the benefit of the doubt, but clearly, I was overly optimistic for nothing.
Style-wise, it tries to be dramatic with a sense of gravitas in the beginning, which isn’t bad per se (if done right), but here it felt very much forced. Then there are the overly clipped/short sentences. Used sparingly, that style creates momentum and mood, but this story uses it ALL THE TIME. I get the intent, the MC is being slowly dehumanized as a deep-sea creature, but it's is so repetitive it loses all value. There are ways to convey that feeling without being so literal. Honestly, the sentence structure was the first thing that tipped me off to it being AI-assisted :/
Grammar-wise, I’m not the best judge, but I didn’t spot obvious typos. However, if it was AI-assisted, it was definitely "smoothed over", but the sentence structures felt very mechanical, but again no major complain.
Story-wise, the first chapter actually hooked me. Unfortunately, what followed felt repetitive and monotone, giving far more space to the "system" than the narrative. The system completely overshadowed the action (insert repetitive system actions we don't necessarily need to understand the story and its progression) I felt like I was reading a computer/system screen rather than the MC.
Speaking of the character: can we acknowledge that the MC was a fisherman (as said in chapter 1)? YET he constantly wallows in guilt over eating for survival. I understand the inner conflict initially which was actually fine by me, but there has to be character progression at some point. The guy killed fish for a living, he should get over it, especially several chapters in. This overshadows the body horror that should have been weaved into the story imho. The character felt flat overall, which, again, maybe cause of the

I made it to like chapter 13 or 14 but it’s very obvious the amount of AI being used for this story and whip that suspicion in mine I checked with ChatGPT and it says between 85 to 95% of the story is AI written, bro please add it into the title. This isn’t cool
