With thousands of years of accumulation of civilization, humans have gradually climbed to the top of the food chain and become the rulers of this blue planet.
But this is just human beings' wishful thinking. As early as hundreds or even thousands of years ago, a kind of monster was born in the world - the mind demon.
They come from the abyss, enter and exit the human world at any time, eat humans and suck souls, and treat humans as domestic animals. In order to better capture humans, the abyss will erase any human memory of the abyss.
At the core of the abyss, there lives the most powerful mind demon in the entire abyss - "evil". It formulates the rules of the abyss and the world, and nothing can defy it.
