- Description from Uukanshu

Set in a Pokéverse where the remnants of our civilization's Earth lie buried under the resurgent human/Pokémon societies, this epic Saga follows the protagonist through his journey to the heights of Pokemon Training and beyond, across a planet that was only saved from ecological disaster by an act of Arceus. As Humanity and Pokémon coexist in this fusion of settings, the story will explore themes of war, oppressive cults, and Shadow infusion, in a world where Pokémon healing and battles echo the anime in realistic, but not overtly graphic ways. Pokémon do not rip each other apart in Battles, though it can sometimes happen in the wild.This is a very long journey fic that's kind of a Crossover with everything. But with Pokémon. So you might see characters like Shaggy Rogers, or Izuku Midoriya, but with Pokémon teams. Pokémon legends like Red, Gary Oak, and the reigning World Champion, Ash Ketchum, are also, naturally, present in the setting. Think of this slice of the Pokéverse as one where it's all coming together.

Scholar System, Business System, Confucian Saint System, Oracle System, Bald System, Ancestor System, Myriad Realms System…This is a world overflowing with systems!In this world, everyone can awaken a system of their own!Everyone can cheat their way to the peak of life!However, Xiang Beifei was utterly confused, “Why do all you locals have system cheats while I, as a transmigrator, don’t have one?”Soon, he realized—Not having a system cheat was actually the biggest cheat of all!

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.
