like, its about this dude, and he learns that he can level up. sadly, its not that simple. it follows the logic of a non human reincarnation story. basicly, if he kills a human, he levels up.

it begins by him killing his grilfriend for whatever reason. that is when he notices the floating screen, telling him that he leveled up to Lv 10.

it then tells him that evolution will commence.

he is confused, scared and sad as all hell, but even in a situation such as that, he falls asleep.

when he wakes up, he notices that his nail hav grow by about five cm and have become sharp. even if he were to try to cut them, he finds it impossible.

on his head two bumps have appeared on either side of his forehead.

his spine seems to have grown, and his butt hurts. 

he is a pretty competitive person, and he loves video games and mangas. due to this, he comes to the conclution that this is actually a matrix like world, where he is the player. all other people are npc, and therefore ok to kill.

but he knows the cops can catch him at any time, so he hides his girlfriends body.

If you encounter this narrative on Amazon, note that it's taken without the author's consent. Report it.

he then goes on to kill another person, only to be dissapointed as he didnt even gain a single level.

he then calls over his sister, and kills her. to his great joy, he gains 9 levels.

he kills a few more, and finally he reaches level 10. an announcment tell him that he will evolve.

when he wakes up, he has grown a tail and blood red horns are petruding from his forehead. his claws have grown longer, and he no longer needs a knife. when he tests the strengh of his skin, he finds it to be able to survive a direct stab.

he concludes that the more emotionally attched he is to someone, the more exp. 

he kills his family, but it isent enugh.

he travels out to the country, and demolishes an entire village.

the cops come, but he has already escaped.

he evolves yet again. 

this time, he can see arms forming under the skin of his back. the tail has gotten a sharp barb, and has turned a pitched black colour.

the horns have become sharp as needles, and are many decimeters long.

his teeth has grown sharp, and his eyewhites have turned black. his pupils have become a scarlet colour.

he finds that not even a gun can go through his defences.

he decides to destroy the city. 

as the city lies destroyed, he tastes human flesh.

it gives him more strengh, so he decides to eat the corpses.

he evolves yet again.

his entire body has become pitch black and large wings petrude from his back.

he has grown another pair of horns, and his fangs are as sharp as his claws. 

he goes on a rampage, killing all in sight.

finally all is dead. 

only he remains on this deserted planet.

no longer is he a dude.

he is a demon.

only now does he realize this.

he breaks down, tears flowing endlessly in a stream.

the end.

fuck, that was wierd...
