Liu Rufeng had no choice but to get straight to the point. "All right, you're about to die. What do you want me to do?"
"Promise me something."
"Tell me."
Zhang Qingshan lowered his voice. "I have a younger sister..."
Liu Rufeng was taken aback. "I didn't know you had a younger sister."
"That's not surprising. I haven't seen her in ten years. She was only ten when I left home." Zhang Qingshan gave a bitter smile. "But she's still my sister. Even if I die, the gang leader won't spare her. I know she's with him now. I need you to promise me: protect her, even if it costs you your life."
