Andrew walked into a strange room. When he entered the room curiously, he found that the gate was missing. He was horrified to find a rune on the wall, which read: This is a magic room. When someone enters, the exit will be closed. When there are two people in the room, they must have sex before the exit of the room will be opened again. Andrew was taken aback when another unlucky guy came in. "Merlin's beard! It's you! " He couldn't help screaming.
