Demon Slave Marries Same Person

World view setting: Dual identity conflict: Qingci, a modern female student, traveled through time and became Kirigiri Qingci, a cold priest of the church. Her lively inner personality is in sharp contrast with her original personality. She must carefully maintain her personality to avoid being discovered by the church. Rules of Magic Society: Magicians and church forces are in opposition, but in fact the top leaders of both parties know certain secret cooperation rules. There is a delicate balance between the Holy Sword user and the Demon King.
