The member of the Riders organization with a red scarf on his face passing by with a group of students following him was just a simple interlude. Whenever they passed by a particular building, the Rider member would point out to the others what the place was. He would even explain to the students behind him what people did here.
Actually, this field trip felt more like a fall tour. Or rather, it was a kind of social learning class for the college students to see what the outside world was really like.
Ren Xiaosu believed this Rider must have brought these stronghold students to look at the refugees' living conditions before bringing them here to the black market.
