An alien planet called Fate, N billion light-years away, sent a group of researchers with "atavistic" characteristics to investigate the whereabouts of the first group of researchers who chose to betray more than 400 years ago, and at the same time find out why they chose to stay on Earth and reproduce with humans.
In fact, I want to use Fate Planet to depict the future Earth in my fantasy.
Since my knowledge base is too little and there is no scientific basis for it, I just want to make unrealistic yy. Don't correct the objectivity of the content. I'm afraid you won't be able to correct it even if you are bald.
Pure imagination.
