Because I have experienced death,
So know how precious life is.
Because I have been caught in the rain,
So I want to hold up an umbrella for others.
Wuyou and Bili are the souls of the dead. They used their abilities to create a paradise to provide a haven for people living in "darkness" and guide them out of their predicament.
Duanmujin and Li Jiaxuan supervised Wuyou and Bili to prevent them from making mistakes, and occasionally provided them with help.
Purpose: Love life
