Trash bags don't move on their own unless there's a stray cat in a large trash can or there's someone.
Yang Yi's heart tightened because there were people next to that garbage can, and there were two of them. Why would two people be standing next to the trash can? Because it was on a street corner.
Guarding the corner and then searching house by house was a standard search routine.
But how long had those two been there?
Yang Yi took a breath and then smiled at Xiao Ran, "Do you have any trash to throw away?"
Xiao Ran hadn't noticed before, but after giving Yang Yi a strange look, she whispered, "No, oh, yes."
Xiao Ran opened her small shoulder bag and pulled out a few tissues, wiped her face with them and then naturally looked towards the garbage can.
The garbage can was large, the kind that nearby residents used for their domestic waste.
Talking to Yang Yi, Xiao Ran approached the garbage can and then casually tossed the used tissues into it.
