The other four players did not have Su Yu's ability to fly high and observe the entire map; they could only fumble their way through the forest.
Fortunately, the public chat channel was open, so they could probe other players through the channel.
Sandwich Sugar: "Boss Ke? Is that really you, Boss Ke? I'm a fan of yours!"
But Su Yu was busy surveying the entire map at that moment and did not respond to him.

Denial of Clothes: "Well, looks like Boss Ke is pretty aloof... Let's get down to business. I'll disclose my role first. My card is 'Loyalist'."
System prompt: "Player [Denial of Clothes] has revealed his role. His role card is confirmed as 'Loyalist'."
Denial of Clothes didn't do this without careful consideration.
By revealing his role, he could quickly join forces with his lord to fight others, so they could distinguish friends from foes instead of being in the "dark forest" with everyone turning against each other.
