Introducing...

Eden's transmigration was quite real. After all, he has lived this life for the past fourteen years.

In Eden's past life he was a scholar where he died at the age of twenty-one, the next thing he knew, he woke up here in three years old baby body.

According to this world history, humans originated from planet Mira. After thousands of years of advancement in technology people left Mira for other habitable planets.

The advancement in technology never stopped. No, it actually started to change rapidly. The change was so rapid that if any person from any period happens to stumble upon the same place, after five years of peaceful solitude without connection to the outside, he probably won't be able to recognize even his own family.

One star cluster after another, humans started to conquer them and settled there. Within even one cluster there were a lot of planets, stars, asteroids; But humans as they were, they wanted more.

While one group of the population was conquering a star cluster, the other population was conquering another.

When they were on the journey for advancement, they also made lots of enemies. Mutant Animals were basic.

Other intelligent existence who also happened to be on the conquering spree, were the ones that have given humans a real headache.

Even though everyone considered, chances of encountering an intelligent existence beforehand, when they forced to face them, they only had one answer for the situation

WAR.

But that wasn't all. Humans being humans, were are greedy by nature. Within one's cluster system if anyone found a planet with rare exotic minerals then the obvious answer was, "Heard you found rare exotic, sounds like you need some freedom."

Hence, the enemy of human were not just these mutants and other intelligent beings, they were human themselves too.

In the end just to make sure humanity prevails against these aliens; an association was established.

Galactic Association.

The association establishment ensured humanity's victory over aliens. On top of that, they started to lead humanity on technological advances and research regarding mutant animals and other aliens.

Starships were used to battle in space. While military forces were used everywhere except space. This still caused heavy losses in human life.

To stop this, humanity first developed combat robots, which turned out to be a total failure.

Then came the age of mechs, which wasn't a total failure but was still concluded of being impractical. They were still in use though. But when one compared, the ratio of the number of military personnel to pilots, Pilots were almost nonexistent. And mechs while it was considered as a deadly force, one couldn't deny that it was a huge target. Hence the mechs still came in use, but rarely.

Then began the era of combat suits. One of humanity's strongest tech that was able to be used by anyone. Military personnel, mercenary, contractors,... just about everyone; the only thing they needed was money to buy one.

At the same time, another group of pioneers was successful in the development and production of gene reagents.

In other simple terms there arose a competition between these two groups of the pioneer.

After centuries of advancement, the Galactic Association was again further divided into two branches.

Mechanics Association and Gene Development Association.
