The hidden wolf is the soul of wolves in this chessboard. As the only werewolf who knows all his teammates from the beginning, the hidden wolf needs to take on the responsibility of connecting wolves. In the dark night, the hidden wolves can choose the prophet who jumps violently, and hint at the identity of their teammates during the jumping, thus uniting the wolves. One of the simplest examples is that the hidden wolf jumps the prophet to give the wolf crow's paw golden water, so that the little wolf and the wolf crow's paw can recognize each other as teammates of the hidden wolf.
