How do hermits who are stained with blood speak?

Hermit suggests telling other players their identity as soon as possible, so that most of the wrong information obtained by players in the just camp can be explained, such as the wrong information of chefs, mind readers or investigators. At the same time, other characters who can get more information, such as fortune tellers and crow watchers, can also skip hermits. However, other players may still want to execute the hermit directly after learning the identity of the hermit. Or, a hermit may not reveal his identity until the last day. If the hermit can know which players are strangers, or who are wrongly registered, he can convince the players in the just camp that he is actually a stranger. However, because the justice camp often directly executes hermits, it has no advantage for the whole camp, so it is helpful to win by surviving in a necessary way.
