There was a story about the Endunami told to children when they were young. This story was about a five-year long war between the aliens, called Endunami, and the humans. The aliens were born with internal power and declared war on the humans for resources.
The humans had to evolve to survive, making all types of experiments one after the other. After miscellaneous trial and error, they finally found a solution to put an end to all of this, supernatural abilities that surpassed the Endunami.
They made an injection, which was tested on various short-lived animals to inspect the generational inheritance. This injection could be passed down in genes, from generation to generation. The humans had to train their bodies, to survive the aliens and the injection. This injection was used in food, drinks, pills, etc.
Soon, the humans prevailed against the aliens, the aliens had too many casualties and were forced back into a different universe. They were lost in this universe for decades and eventually repopulated. In this story, however, after 150 years the Endunami attracted back with advanced technology.
