"I used to live in the town next door. When the extreme heat arrived, my parents brought me to this base. They said that there were mountains and water here, so it'd be cooler here than in the town. After that came the extreme cold, and the temperature plummeted. Two days later, we could hear the howls of wolves when we slept at night. Last week, we went to bed early. In the middle of the night, a wolf's howl suddenly sounded from outside, and it sounded very close to us. We wanted to escape from here, but it was dark and cold outside, and there were wolves running around. In order to protect me, my parents were bitten to death by the wolves..."
After saying this, the boy's eyes were already filled with tears.
Du Yue was quiet for a moment before she asked him in a low voice, "How many people were killed by the wolves that night?"
