My Girlfriend's Whole Family Is Ghost, I Saw My Parents Pretending to Be Ghost Kings

Xu Ming had been dating his girlfriend for three months, but her parents wanted to see him. I thought it was just a normal meeting with the parents, but my girlfriend revealed her cards: Her whole family is full of ghosts, and her parents only want the son-in-law of the ghost king! In order to help Xu Ming pass the test, the ghost girlfriend made some unreliable suggestions: Pretend to be the Ghost King and get away with it! At this time, Xu Ming happened to activate the Demon God System. His girlfriend thought he was an ordinary person, but in fact he had quietly become a demon at the top of the food chain. On the first day I met my parents, my father-in-law and mother-in-law were all frightened and fell to their knees... This novel and its characters are purely fictitious.
