Seeing the question, Kong Yuxin couldn't help but frown slightly.
Clearly, this was the last player from Community 8 entering the room, announcing the current status of players to everyone to help identify which order of players are allies.
Using birds as a metaphor is an internal code between Community 17 and Community 8; anyone not using this metaphor can basically be confirmed as an outsider enemy.
Because in some extreme cases, the last player entering the room might also be from a hostile community.
If it was only agreed to report room members truthfully, without setting a secret code, the hostile community might provide false information to mislead.
If the last player doesn't choose to use 'bird' as the secret code to report, Community 17's players would see him as an enemy.
This way, Kong Yuxin can also completely confirm the sequence order of her own players.
After brief consideration, Kong Yuxin chose option B.
