The team investigates the ancestral hall and sees a tablet, Yu Cai Zhe, mysteriously fall to the ground. They encounter a blind, homeless boy being beaten by a guard. They help the boy, who is a victim of human trafficking but can’t be sold because of his weak body, so he is instead forced to steal for money and survival. Another team gives them a clue that Yu Cai Zhe’s memorial tablet is, in fact, Ms. Yu’s son. (Source: frankly at MyDramaList)
