Evolution

My birth didn´t go as I expected. Instead of getting born normally, I hatched from an egg.

Its been a year since I was born in the tribe as a boy named Kravas and I learned some thinks about this world.

There were no races here and evolution was currently working overtime, everyone here had physical trait that could be inherited by their descendants. This resulted in a society where these with the strongest genes get worshiped by the opposite gender.

Tribes were formed when a genetically strong being has many spouses and they have kids. In return these kids leave when they don´t want to stay under the leader anymore and make a tribe on their own.

As a result of these circumstances I was born as a bald humanoid with two pairs of arms, two pairs of eyes, two dicks, two rows of teeth and a grey, stone-like skin, I looked pretty human if you ignored all this and my size. The smallest being I have seen as of yet was around 2,3 meters and I was sure I was going to surpass that once I reach adulthood.

Now the second thing I learned about was this energy they simply call Vitality. I wasn´t sure what it did so I didn´t assimilate it into my NE when I arrived here but I am sure that it is the reason why everything here has an overwhelming sex drive.

Vitality was different from my NE because it didn´t come from the soul, in fact it didn´t even regenerate. There was only so much stored in the body from birth on and the among was determined by how strong the genetics were. That explains why everyone here is so set on passing on the best genes, even if it is instinctual.

From what I discovered till now, Vitality was gradually strengthening the cells as you grow older until you don´t have any more left. I had the feeling that there was more to it than that and no one simply has had enough Vitality to reach the new stage. In a way you could say I arrived too early as evolution hasn´t reached the point yet where live in this reality had enough Vitality in them.

I was a little worried what would happen if I added Vitality to my NE because my cells would start to be refined by not only Vitality but any other energy I have absorbed in my NE. If things didn´t go well I might have a big problem because my NE would affect every body I would possess in the future.

I was conflicted because while there was a huge risk there was also a huge gain. Should it work, I would not only easily have enough energy to reach the next stage and any stage after, since my NE can regenerate, but I would also have a body that is at least partially made of NE, making me immune to any energy I have absorbed without having to coat myself in NE.

I wasn´t going to make this decision hastily, I had time, in fact I had even more time than I did in any of my previous lives. This body isn´t the result of evolution for nothing and I was already stronger than a peak human while only being one year old and I knew that this included lifespan as well. I heard that the tribe leader, my father, is already over 200 years old and he is still considered to be in his prime.

I decided to first life the next few years normally. I had to admit, I liked this primitive but simple lifestyle a lot, it was honest, upfront and simple. The material was still too hard for the current state of evolution to properly use, so houses were made of sticks, stones and leather, you had to search for naturally shaped, sharp stones to be able to chop trees and if you liked someone you just had to defeat them in a fair fight to get the right to mate with them. All in all a world going after the motto of survival of the fittest and might is right.

I spend the next 20 year enjoying living like this and not much has changed. Some siblings left to create their own tribe and some woman joined to bear the chiefs strong children, so the size of the tribe stayed pretty much the same.

Despite enjoying my last two decades, I knew it was time for me to make the decision that would influence me for the rest of my eternal non-existence.

I was already physically stronger than 80% in the tribe and I still have 60% of the Vitality in me left but I know that this wasn´t enough to reach the next stage. I had hoped to first reach the next stage to see what it was, before making a decision but now I had to take this risk.

I left the tribe and made myself a cave inside the nearest mountain, using magic for the first time in 2 decades. I didn´t know what was going to happen if I suddenly changed the type of energy when my body has already been strengthened by another one, so better safe than sorry.

Once I made myself comfortable, I released my NE into my body. The clash between Vitality and NE lasted only for a brief moment before being swallowed by it without being able to put up much resistance.

I could feel my NE replacing the Vitality in my cells and undoing any changes that it did during the last two decades. That process was by no means painless, in fact it grew painfuller with every cell that started changing, until even my brain started being affected and I passed out from the pain.

I thought I was familiar with pain but never have I ever felt the pain of my braincells reconstructing themselves in a matter of seconds.

A/N- I spend the last few weeks thinking about how to structure the world, hope you like it and give me some tips of what I could add.
