Should Wild Men Pick It Up?

They say you shouldn't pick up wild men on the roadside, but Shen An didn't believe in evil and not only picked it up, but also secretly kept it for 6 months. Six months later, the man ran away and the family was gone. Alone and helpless, she went to Beijing with clues and evidence to find the truth. The village was slaughtered, and the tokens left vaguely pointed to the wild man.
