In the Old World, I Was the Only Ordinary Person in the Family?

Su Mi traveled to a parallel world and became an ordinary high school boy. He has a childhood sweetheart who smiles beautifully and is full of energy. He also has a good-looking, handsome and good friend who he can talk to very well. But from one day onwards, Su Mi suddenly discovered their secret... The energetic childhood sweetheart is actually a veteran horror escape world player? My handsome best friend is actually the head brother of the Immortal Cultivation Sect? Su Mi was shocked, but this was not the end yet. After his father, mother and sister came back from being away for several months, they told Su Mi that they had just returned from a trip abroad to remove spirits, and the main force in removing spirits this time was actually his sister who had just turned 14 years old. Su Mi: "You all have special skills, what about me?" Father Su: "Son, there is something I haven't told you. In fact, we picked you up from the orphanage and trained you as a son-in-law since you were a child. Isn't your status as a bride-in-law special?" Su Mi: "???"
