Future Queen of Darkness

In the future world, when the rich can live forever and the poor can only be destroyed by humanity, another kind of power suddenly awakens in the poor. With supernatural powers, the poor and the rich can deal with each other. But the rich still live in a luxurious world, while the poor can only exchange their lives for survival capital from a place called the "Devil's Arena". Some people want to overthrow the rich man's paradise in exchange for their own lives. And Mo Yu, who was supposed to be the princess of the Mo family, was kidnapped on her eighteenth birthday, the day she could start to inherit the family. When she woke up, she had appeared in the devil's arena. No one in the Mo family, or even in the world of rich people, could remember the existence of Mo Yu. She finally had to completely belong to the darkness.
