Did the werewolf kill someone who had his own room to listen to?

1. First of all, the monitoring position in the game is in the attic, and the crystal inside is the monitoring.

2. Secondly, the crystal can be used to watch the real-time monitoring of some positions, which is the most convenient way to find suspicious players. But the werewolf killer has his own room to monitor. But watch out for someone touching the attic.

3. Then the crystal can see the intersection of the attic, the right side of the hall, the intersection of the divination room and the intersection of the energy center.

4. Finally, the information seen in the monitoring is easily distrusted by other players, because werewolves also have the right to see the crystal.
