I can't. Killing in Heaven Space is a brain-burning reasoning puzzle game. The game is similar to werewolf killing. Here, players will enter outer space with players who have already matched online and launch a spiritual confrontation. According to the official strategy of the query game, the only use of the night watchman is to put a black hole in the warehouse and then put a black hole farther away. Spies can't jump into the night watchman's black hole. A spy needs to beat everyone to win.
