100,000 years ago, a meteorite crashed into Earth, granting a 17-year-old caveman the power humans have craved for millenniums, immortality. Though originally a savage and cruel caveman, millenniums have let Acheron refine himself and surpass the epitome of Humanity,  basically, a god on Earth. With his power, he mastered all forms of combat, every language, all the arts, and much more. He sometimes helped create empires, sometimes built empires, sometimes destroyed empires, at times, even his own. Today, mutants with superpowers walk among the public, it is kept a secret by the governments throughout the world, and events pertaining to them are covered up but doesn't stop Acheron from interfering with their plans.

2 months ago, his oldest adopted daughter passed away, she was 96 years old. Though he cherishes all the children in his family, she was without a doubt, one of his favorites. 

"Her last wish was for me to have a normal life but what do children do in this era?" Acheron asks one of his adopted sisters. "They go to school, Lord Acheron," she says. "School? Right!... Will it be entertaining?" he asks, "It would at the very least be a new experience" she replies. "Make it happen!" he orders. " Yes! I will do it immediately, Lord Acheron" she says.
He, who was there when the first Homo Sapiens migrated out of Africa and existed way before the wheel was created, will let nothing interfere with his daughter's last wish and will slaughter anyone that stands in his way.

P.S this is not a Marvel or DC fanfic

This is bad writing, with entertaining content.

Reviewed at: Chapter 39- New Exhibit

Op MC, Harem building, secret global domination. Scarred main protag, generally an ass, but his people love the dude. What tropes can I say now, you've already read this story bro. Regardless of that fact I'd still recommend this story for consumption. It's good enough. A guilty pleasure read. 

This story won't change your life, you won't be inspired by the characters, the plot is nothing to write a Symphony about, and ultimately suspense is just not in the authors vocabulary, but despite that, there's something about the story that makes me wanna read on. There's no depth here but I'm still having a good time. There's no secret that isn't quickly brought to light or sudden mindfucks. It's pretty cut and dry, actually. But that being said, it's only that way because people love the process.

Ultimately if you suspend your disbelief and don't think too hard about any given protagonist that acts like our Main Protag, then yeah, you'll fuck around and enjoy yourself. So give it a shot.

I like the concept of this novel, the best parts have been as the author blends the MC into the history of the world, explaining how his influence affected the state of the world and how hes gotten as strong as he has. To be honest, despite being called OP, I still don't think the MC is as strong as he should be considering how long he's lived but maybe thats my overestimation on how useful extra time is, it probably plateaus after a certain amount. Anyways, if the description hadn't already warned you away that this was an OP harem story, then ill say it definitely is. Even if those things arent your cup of tea, this is still worth a read.


Not gold but decent among its peers

Reviewed at: Chapter 10 - Music Opportunity

 Neat to get another story like these. 

But if you're a seasoned reader of urban op school fantasy litrpg, you will find that this one doesn't change the mould these stories come in.

In other words it is full of cliches.

Don't expect a masterpiece or anything exeptionell  and enjoy a few laughs.


So yeah I like the story. I think it is awesome. For some reasons authors can't grasp immortal or overpowered charachters all that well but here thats not the case. I find he captivates how an 100 000 still good looking dude would act. Of course ya gotta go to school and have some awesome secret bases, ..... 


I very much liked the background story side arcs where you give more depth in his past. 

The harem is OK. To bad he couldn't stay with the first woman.


What is truly geniusly written but kinda sad is that his sperm draws lifeforce so he can't concive children. You gotta see him as a kinda perfect being so he has no need for children (blood related children cause his need for procreation is nullified.) He solves this by adopting other children and raising them. 

It would be cool to see a Blood related child of him.


Ch 33 The mc is god, the mc is love, the mc is self insert in the sense that the universt turn around the mc.

You remember a japanese story where the mc hide his power but at one point he show his power and everyone can't help to comment on how impressive he is?

This novel is this, with the mc don't hide his power.

This is unique but i know if the story don't put a chalenge to the mc i will be bored and this is not a story for everyone.


So far so good. I am very interested in the way this will progress. Seems like it will turn into a harem story which isn't bad in my mind but slightly over used. My only real complaints at the moment are occasional grammatical and wording mistakes. Not enough to make it impossible to understand, but enough to brake the flow of reading and give me pause as I take a second look to correctly understand that sentence. My score is based off my overall feel and enjoyment of the story far more that the technicality of writing. The MC feels kinda like saitama from one-punch, just not as naive or oblivious. He doesn't hide what he can do, but also doesn't throw it in your face. I would strongly recommend giving it a read. You can probably tell if you will like it or not in the first few chapters.


Great to see this story on more sites,
A bigger audiance is always great.


Story is amazing with an immortal character whose gone through life in interesting ways. He didn't start out as some god he suffered 90,000 years of loniless and torment. Before making his family and did I mention he absorbs other Mutants powers. He also ain't no simp MC he gets them girls but isn't like every Mc in harem story seducing ever woman he sees. The romance build up happens naturally and there's a good amount of detail on his past and the overall history of this parallel earth and his interaction in it over the past 100,000 years. Goes into a fair amount of detail around the world and its interactions shows a lot of emotion but still keeping it hilarious. The action scenes are incredible a lot of fighting and Mc is brutal. Has a wide cast of characters who play important roles whether it be in his past or in the present and how they defined him. Including on why he's attending a super high school occasionally rest of time he's traveling the globe. The Mc also loves trolling people  It shows he intreracted with famous historical figures and people from legends his growth as person and his desire to die but being unable. This world is full of mutant characters. If I were to describe it those Universe is like the X-Men universe and a fantasy world had a kid who then had a kid with Sci Fi Elements and had Martial Arts/Wuxia ancestry.
