Fifteen-year-old Yan Shen led an army alone for the first time and was ambushed. Three hundred fine knights were destroyed, and he escaped and fell in the snow. A nine-year-old girl dragged him into a cave and made a fire all night. She left at dawn, leaving him the old cotton-padded jacket. He didn't ask her name. She didn't say anything either. Later he found out that the village was massacred because of him. Her adoptive parents and her sister all died in the fire. The person she saved was him. --- Eight years later.
