Yu Sha knocked out the group that mobbed Lali's father and returned to the same place to check his condition. Seemed like he was hit in the head pretty hard. Although that was her original plan, she didn't intend to cause extreme internal injury. She just wanted to scare him and threatened him a little so he would never search for his wife and children. He had never been the father he was supposed to be, protect and love them. There was no need for him to be in their life when he contributed nothing. Seeing his condition, she lost the will to do anything further.
Yu Sha picked him up and threw him by the roadside. She went back to hide in the tree and waited. Her plan was to see if a car would come by and discovered him. Since it was late at night and the city was on the outer skirt, few cars traveled by. If no car drive by in the several minutes, she'll have to take Plan B.
