After My Biological Daughter Was Bullied by the Adopted Daughter I Had Been Sponsoring for Two Years, I Went on a Killing Spree

I was away on a business trip abroad for a year when I suddenly received a selfie from my daughter. "Daddy, Nini misses you." I thought she was upset because she missed me, and I was about to reply and comfort her when a scratch on her collar caught my attention. Zooming in on the photo, I realized that not only did she have a scratch on her neck, but she also had dark marks on her arms.
