Walking with a heavy load tells the story of my mother being infected into a zombie after a car accident. Dad woke up and got out of the car and was desperate. Suddenly, he heard crying. After seeing the children, he regained his confidence in life. He picked up the child and found himself infected. In order to keep the child alive, he decided to carry him on his back. In order to prevent himself from eating the child, he took out the internal organs from the deceased and hung them on his chest with a wooden stick. In order to keep the child quiet, he took out the balloon from the passing house and put it on his back, but the child couldn't get it. In this way, after he completely turned into a zombie, he looked at the internal organs hanging on the stick in front of him. The child played with the balloon quietly until he was found and killed by a sniper rifle. People looked at it and left. When he was about to leave, he heard crying, only to find an uninfected child, and then found the child's name on his father's arm. Super touching, although only a few minutes, but everywhere reflected that blood is thicker than water (carry forward)
