Try to be as powerful as my sister
Setting: 1. Level
It is said that every time a building is built, there are only 20 steps from the first floor to the second floor. If there is one more floor, it is the soul of the dead (person who cannot be reincarnated) who comes to this building to rest. If a stranger steps on the 21st floor, he will know the resentment of the soul and be parasitized. Only after being bound and refined can he go to reincarnation.
2. Become in love
There are two types of people in the cleansing stage
A kind of tool is used to refine the souls of wronged people (the "tool" should be something that has been worn since infancy, because it represents the "pure and good" jade is the top grade, and it can also be the purest thing)
The one that relies on "heart" is very difficult. It requires the soul to be extremely clean and free of divine punishment. Refining it with your heart is very rare. It is also easy to be parasitized by wronged spirits.
Concept: It was probably a setting that suddenly came to mind when I woke up.
