The Supreme Immortal Cheng Ying Xingjun, who is in charge of the life, death, misfortune and blessings of mankind, is just as strict and unkind in private as at work, and has tense relations with other immortals. Dudu is very fond of the kitten demon who has just entered heaven.
After getting acquainted with Xingjun, Ajiu discovered that Xingjun's soul was not a complete human soul. For some reason, a piece of it was missing. Therefore, he was not cold and indifferent, but just lacking in emotion. Ajiu secretly made up her mind to find the missing part of Xingjun's soul. Ajiu went down to earth on the grounds of past tribulations and found the other half of Xingjun's soul. Unintentionally, she was self-defeating and caused chaos in the world. She also learned the secret that belonged to her and to Xingjun four hundred years ago.
