Two thousand years ago, human beings were chasing immortality, and gods showed the way. They met their own demon pets, fed them with their blood, and gave their hearts to the demon pets for safekeeping. The demon pets practiced and transformed into demon energy to keep the human heart and make it fresh. In this way, people could live forever.
The gods assigned Flo to take charge of humans and demon pets. Unexpectedly, a thousand years later, human beings will live forever and the world will be in chaos. The world's resources are limited, gold and silver are limited, but human beings will live forever and continue to reproduce, and contradictions will gradually emerge. Humans began to kill each other, but they did not die. They could only seal the corpses and demon pets. In order to completely eliminate the opponent, the rich man began to destroy the demon genealogy so that future generations would not be able to pet the demons, and then killed the demon pets. The demons were implicated and tortured to death in order to protect their master's heart. Finally, the goblins gathered their resentment and counterattacked the humans. For a time, the human-monster war was in chaos. In the end, the fairies could no longer defeat humans, and the fairies gradually declined and were almost extinct.
The stupid gods finally understood the chaos in the world. Put the blame on Flo and blame his poor management. Send him to hell and never see the light of day. In hell, he manages the wronged souls of humans and wandering fairies. He also decreed that no demon pet should be cultivated privately, and that he would be punished if he found one. With the development of human beings, they have gradually been forgotten. Until now, demons have become legendary things.
