Ye Fen, who escaped from the underworld, used to absorb people's souls to heal his injuries and increase his power.
Not all souls can increase their power. She divides the souls that can be sucked into three categories:
The third class: the souls of ordinary people; the second class: the sweet aftertaste of good people's souls; the first class: the bitter tea-flavored souls of evil people who turn around;
It's just that she has to think of some ways and use some force to make the evil person turn around.
Now that she has learned ghost arts, she must practice them to the best of her ability, and become as powerful as those who have magical skills.
Intention: Even if we are ghosts, we are also motivated ghosts
