Well, this is YY's work when the unscrupulous author was suffering from the second grade of illness. All the characters are YY by the author. As for the plot and other things, the author will have it whenever he gets sick~
Ahem, this is a story about modern people traveling into an unknown world.
(This world is really unknown, dear, because the author has not completely finished YY, so anything that introduces the world will not happen, and it is reasonable to happen in this world!)
Just treat it as an article to entertain yourself - the title and content seem to have nothing to do with each other (?)
