The reason that this whistle made her heart stir was that it had been made by Lan Qingyou and Alisa working together.

So.

With Lan Qingyou not having blown the whistle, the only person it could have come from was Alisa.

It was a method of communication the two of them had come up with during this time.

Alisa nodded
